Best believe I'm here acquiring information for one of the characters in my head. He is a handy man and I need him to know his stuff. 😅️ Thanks. I couldn't move on with my love story because I needed them to have conversation that revolved around the handy man's knowledge. Now I've learnt a little something too.😅️
Awesome! My sister is an author and it's fun to hear about the research she does for her characters as well.
Your lecturing is very informative.. Thank you..
Its hard to convince some older people to make the change to LeD they still love their old 100w Halogens
Leds are not good for health ok
Get up to speed
😂😂
Probably the best video I found on this topic explaining every part in enough detail to reach at good conclusion with good examples and really good way of presenting.. @CircuitBread good job!
Thank you, that means a lot!
@@CircuitBread it's fantastic! I did not know about the Blu-ray wavelength association. Every day you learn something new is a good day
He's a really good host! Entertaining to watch, informative, very in-depth sounds like it was written by an engineer (i.e: really really good). the video did feel a little too long though, I had to speed it up by 1.5x XD so maybe pick up the pace without losing information if that's possible! Great video
Edit: Also the video editing is great love the infographics
Edit2: oh and maybe you could go more into the hard science like I appreciated how you started off by saying how the incandescent light is basically tungsten on fire but you didn't give the same treat to the other lights like how fluorescent is caused by charged particles crashing into the gas causing emission of light due to the energy levels n stuff
Thanks again for the feedback - it's this kind of stuff that really helps us continually improve with our content!
Yeah, pacing is something that we're always trying to get right and it's tricky because some of our content is very dense and technical an maybe warrants a little slower delivery, while other videos like this one are a little lighter and it's better if we keep them humming along at a good pace. We're curious what you think about the pacing of some of our other videos. In general, we think we've sped things up a bit over time, but it's hard to know if it feels that way to viewers.
Great video, but high pressure sodium bulbs will always be my favorite. They light up an entire room, are efficient, and emit this nice orangish white light. I wasn't aware that it was illegal to manufacture mercury vapor ballasts in the U.S, but you could use a HPS or metal halide ballast to power one if necessary. I'd also like to add that mercury vapor and low pressure sodium especially last basically forever. I've seen low pressure sodium lamps under bridges or near observatories last for something like 15 years, and there are a bunch in my city that have been running basically as long as I can remember. Although, one con about HID lamps that you mentioned is actually worse than you described, and that's the cost. When I first got into HID lamps, I spent something like $50 dollars on a ballast for my HPS bulb and on a 4kv pulse rated socket. There's a lot of hidden costs there if you don't already have a ballast that supports the lamp type. Another thing I want to mention is that tube fluorescents actually have better on/off durability than most CFLs. The flickering thing actually causes a lot less stress on the electrodes than instant start ballasts which basically just shoot a high voltage charge through the bulb to start it. It's less annoying which is why most CFLs are built like that, but it does reduce the lifespan. Anyway, great video.
Great organization of information - I'm appreciating these everyday things a lot more as a mat sci student
Very informative and great comparison!
Thank you for such a great breakdown! Also, your voice is so calming!
Nice video. Thank you for sharing your knowledge.
Awesome Explanation - - - LEDs are the FUTURE of Lighting, and you explained WHY !!!
You are so clear and present extremely well. Would have liked you add one more classification in your chart- using indoors and outdoors. Outdoors I mean specifically to frigid temperatures (below 10 C). Thanks again
Great idea, thanks for the friendly feedback! I'd have to look into it more because I know CFLs do very poorly in the cold and some LEDs also aren't great, but I'm not as familiar with the other technologies and their performance in the cold.
Most of the energy that goes into incandescent lamps is emitted as infrared light, not heat. Besides infrared heating, this also makes them excellent infrared camera illuminators.
There is no UV blocking coating on the metal halide lamp. The outer envelope is made of borosilicate glass, which is opaque to the nastier short wavelengths that the quartz discharge tube lets out. In terms of color rendering, some quartz metal halide lamps have good halide mixes and thus good color rendering. Ceramic metal halide lamps also have very good color rendering; the warm white Philips MasterColor lamps I use are on par with incandescent.
Efficiency is only one of many design criteria, not the _only_ design criterion.
Incandescent are good for human health also because of infrared light. They perfectly imitate the sunlight. LED light is dead light, cheaper LED bulbs can even damage your eyes and are migraine trigger.
I like these explanation videos on everyday things we use...thanks for posting!
Thanks and good to know!
Hello CircuitBread!
Thank you for the video. I believe it would be better wheather to replace a test stand or lamp behind the stand, cause it interferes to see the color of test lamp light. Red, yellow, green estimation it's great, but I like numbers as well, e.g. work hours and energy consumption could be added (but it would break the style, I understand). Anyway, you have made a good job! Thank you!
Thank you, Yaroslav! Yeah, the backlit lamp was an oversight, we should have put the lamp on the left side or something else. We'll blame Josh for the color estimation - he was worried there was too much variation even within each technology to quantify easily and that it was better to use colors to just give rough comparisons of the technologies. We appreciate the feedback - have a good one!
Low-pressure sodium lamps are actually the most energy-efficient type of lighting available. They are even more efficient than LED lights, but they are not as versatile or practical for many applications, since they only produce a yellow monochromatic light and are not capable of producing different colors or brightness levels.
Movie studios used low pressure sodium (SOX) lamps to do special effects. The light they produce is essentially monochromatic, so it lets you do interesting film tricks. These lights have a color rendering of 0 so if something is lit by them it might as well be black and white.
The bulb that you have appears to be metal halide, due to the white paint on the ends of the arc tubes. I have never seen a mercury vapor bulb with painted arc tubes. These have a color rendering of 65 in most cases. One can get Ceramic Metal Halide bulbs that can have color rendering of up to 95 which is better than most consumer leds.
True mercury vapor bulbs have terrible color rendering (15-20), but are hard to come by. Most MV lamps found in the wild have “delux” coating that makes them operate more like fluorescent lamps. The color of these is much better (40-60) and can be challenging to distinguish from some metal Halides.
Thank you for the video :):)
Thanks for the extra detail, this stuff is really fascinating!
@@CircuitBread sure! Thank you for the video :):)
That white paint is probably zirconium dioxide or aluminum oxide which serves as a heat reflector to keep the electrodes hot enough to have good electron emission. The Russians often use chromium dioxide for this purpose (these lamps are very distinctive due to the bright green reflectors). The only time you see these reflectors on mercury lamps is in the small 40W, 50W and 75W sizes, both to improve warmup time and to improve electron emission in the higher operating pressure of the discharge tube of 15 atmospheres or more. In these mercury lamps, the heat reflectors are usually platinum paint.
Keep in mind that the tones that are more blue-white in color are not good for your eyes. The more softer yellow tones are noted to be better on the eyes. I guess the bluer tones are tough on the retina. There hasn’t been much in the way of studies on the heath effects from LED light bulbs. I think this is a must, especially since the government is pushing all LED replacement light bulbs, and you can’t find any regular incandescent light bulbs at the stores. Lot’s of talk on energy savings, but how do these LED bulbs affect your vision and health?
i've recently ''studied'' this topic and found that LEDs are not good for the health. now I've changed all my lighting in the living and bedroom back to regular old light bulbs.
its just the real thing and not some imitation of light. we're all getting fooled because of greed. always follow the money - especially if something gets replaced with only one option.
@@violet_world9385 LEDs are indeed bad for your health. They affect your circadian rhythm and are harsher on your eyes than incandescent.
@@John-bs5ugis it the color of the light or another aspect of their performance? Becuase I use 3000k yellow leds for light and they definitely feel better on my eyes than the old leds i had
@@Tipman2OOO The main problem with LEDs is that it's a completely different type of light source than incandescent. LEDs produce directional, but non-uniform light, and it's actually classified as a type of laser. They flicker rapidly and that can cause some people to get headaches or migraines. You also don't get a full spectrum of light with an LED like you do with incandescent bulbs, which aren't directional and give uniform lighting. Color temperature is a way to measure the color of a light source, but even yellower/warmer LEDs contain blue light that affect your circadian rhythm.
@@John-bs5ug really no way? Interesting I'll definitely have to read up more on that subject!
Glad to have seen this video. This answers my questions and give me idea what to buy and not.
Leds are more efficient, but incandescent lights have no flicker and very pleasant warm light. Led flicker so fast which your eyes cant detect but your brain detects it and makes u have headache like myself. Sodiumpressure and mercury vapour lights may have bad colour rendering but they are mire reliable then led for street lighting, many must have noticed newly replaced led street lights turn on and off for no reason on streetlight posts that may be unsafe for drivers. Led is not a fairytale yet like this guy describes it, it still has a long way of development to go
If I could go back and change one thing on this video, I'd put more emphasis on the underlying technology than on the current applications. I still wholeheartedly think LED technology is fantastic, but the last few years have seen some terrible applications. Cost cutting in the driver technology to be more economically competitive with other lights has yielded too many products that are, to be put it kindly, subpar.
Leds not healthy. Check it out
Give off blue light not good
@@christinachristina8271 You can get leds that are yellow with much less blue light
@@portman8909 oh very good
Merry Christmas ❄️
thanks man , helped your video too much , i was confused to buy lamp or LED for my new house ,. big like for you
Loved the way you talk and explain..
Great video. I loved every minute of it.
i thought this was a million sub channel, fantastic work man! instant sub
Been using CFL. Going to check out some LED's. Thanks.
Like anything, they definitely have their imperfections, but personally, I'd take LEDs over CFLs in a heartbeat. Especially now that they're basically the same price.
Thanks a lot very very helpful.
Don’t be afraid to edit, maybe cut down/out a few parts or film parts again. 👌
Ha! Yeah, we're always learning and (hopefully!) improving in all aspects of these videos.
Thank you... very informative. Can we benefit in any way of the electronics in the damaged LED 💡 bulbs ?
If the parts aren't damaged, then they can be scavenged. There are probably some very useful applications for them in other projects.
Hello, why don't you use lamps with a gu10 socket? Could you explain the difference and which one do you consider more convenient?
In the US, GU10 sockets are very uncommon. I'm not certain why. In my house, I only have one fixture with a GU10 socket and frankly, the bulbs I got for it barely fit in and required me to make some modifications to the fixture to do so. I think it's just kind of a de facto standard to use the E26 base. 🤷♂️
🤬 First saw GU10 was about 15 years ago when someone thought that was the best idea for saving time for bulk installation. LED is second stupid extremely slow idea continue in test phase to replace a basic simple light bulb .
I was bouncing ideas off a friend on the theory you could make an incandescent bulb that beats LEDs using some kind of transparent insulation. It was good until I realised you wouldn't be able to switch them off instantly... The insulation would stop the filament from cooling down meaning it would glow until the energy in the filament could escape. The filament was induction heated so it had no physical connection that would conduct heat to the outside of the bulb.
It was either using transparent insulation or an internal reflector to turn the the light into a single point Lazer focused on a coated lense that would reflect the infrared light and stop it from escaping in the beam. The biggest issue that most materials that could make this possible melt at 1,200-1,400°c and a lightbulb needs to heat the element upto 1,400-2,000°c (anything inside the bulb would reach an equilibrium as the heat can't escape). You can make red light at around 750°c but the light emitted would be pretty dull.
I love incandescent and halogen incandescent lighting. CFL is okay but LED sucks as far as I'm concerned
Lights that don't stay on long or get turned on and off a lot, led or incandescent. Ones that will remain on for many hours and if the bulb base will be down like a table lamp, cfl works great. I have more than each type than I really need.
This is a fantastic video.
Great video brother!!
Hi, thanks for putting out these videos, I'm learning a lot. My questions are, you say that LED bulbs have electronics inside them? What does the electronics do? If they only are a DC power supply, is it possible to have one power supply per (say) 10 bulbs? Is this already done? And finally, which brand of LED bulbs have the best, longest lasting electronics for LED bulbs?
Hey Jim! The electronics take the wall AC power and convert it to whatever the LEDs need (a lower voltage DC signal). And while it is a DC power supply, it's attached to that single bulb. However, that's exactly how LED strings or strips work. One power supply that drives a lot of LEDs - though they're not bulbs. As to which brand is best, I haven't done the research, unfortunately, so I don't have any recommendations.
LEDs have rectifiers (turns AC to DC) and current regulators (controlled by a resistor) inside the base.
Electroboom and BigClive have videos on their channels deconstructing LED bulbs and circuits.
Excellent video
What led bulbs would I get to replace a 60 watt E 26 ?
An E26 base is very common, at least here in the USA. You could find a replacement at any hardware, electrical, or lighting store. They're rated with their incandescent wattage equivalent, so it will be easy to find a replacement. I've moved out into the country and our power is a lot less clean than it was in the city, I've noticed some bad flicker that only occurs with my LED bulbs (not LED strips or LED can lights) which I think is because the capacitors are undersized in the bulbs (due to size constraints). Hopefully you don't have that problem as well.
The halogen bulb has to be so small so that the glass will get hot enough for the halogen cycle.
Also xenon for example is a rather expensive gas so a smaller envelope needs less of it.
Halogen bulbs can reach over 30lm/w with IR reflecting glass, a properly manufactured filament and being filled with xenon gas.
It will last longer than a normal incandescent.
At 35lm/w they're equal at how long they last.
Problem with these?
They're expensive but they work that's why 12v halogen fixtures exist as these work best on dc and high current makes a filament more efficient.
For those who wanted efficiency those mostly bought cfl anyways.
What about the fact that led has flicker that is picked up the brain and could lead to seizures or elevated neurological activity and their color spectrum is not as full as incandescent bulbs which is bad for your eyes and skin? Not like I hate LED, but are they better for commercial purpose than domestic use.
I guess you can say that extremely warm environments ore about the only application that greatly shortens the life of led bulbs.
That's true, that's one reason they still use incandescent bulbs in ovens and clothes dryers.
I saw articles that LED Bulb emits Blue light which can be damaging to our eyes. What is your comment and how can we protect ourselves from the blue light from LED Bulbs?
It’s bad if you’re looking at it, like your phone. But the damage isn’t as bad as it seems. Even blue filters on your phone doesn’t really stop emitting it. Just don’t look it, and you’ll be fine. Don’t over think it.
Use red led in that case.
Just try to find an LED that doesn't emit blue light. That might be hard if you want white light, but you could easily find an LED that emits more of a yellow light.
Don’t buy a white light then?
@@123four... they all do... It's just masked by reds and yellows... Blue light is the nature of LED technology.
Hi there
Scientists from the U.S. and Europe warn that LED lights could be doing more harm than good: A 2012 Spanish study found that LED radiation can cause irreversible damage to the retina. ... The report also noted that blue light blocking glasses and filters may not protect against these and other harmful effects.
Make sure you understand the details.
What is technically easy may have consequences related to long term health.
Suggest you revisit the video and explain the technicalities.
Red led is just sitting there in the corner like "am i a joke to you?".
In 2021 CFL are more expensive than LEDs :D
Isn't that insane how things have flip flopped? Incandescents are even more expensive now when I check at Home Depot or Lowes. They've just gotten more expensive as the quantity used has dropped, I suppose. They're basically just specialty bulbs now.
So glad I found you. I was trying to figure out what bulbs to replace. Wish you had said how to find a good quality LED though, or which brand was best.
I wish I knew, honestly. But it's also not as simple as "the best". There are non-dimmable that are very inexpensive with very long lives, but are non-dimmable. Some are dimmable but the prices range all over the place and the quality of the dimming is different. Some have interesting little features like automatic color warming when dimming or are "smart" in other ways. I have not, in the slightest, started to go through all the tests. It would be fascinating to find someone who has, though! Or do it myself, eventually, I guess.
I've had good luck with feit electric LEDs, GE, Sylvania/Osram hell even the great value ones from Walmart have lasted me.
You are a genius, nice video, you remind me of Tony Northampton
Every one talks about the light color and savings of leds but no one seems to talk about the actual wavelength of the actual light itself. What I mean is leds produce a ßtraight light wave that's on the ultra violet side similar to a laser beam leds like florescent cast sharp shadows leds can be harsh on the eyes and some people claim nausea were as incandecents produce a soft fuzzy light wave that is warm and gentle on the eyes wich we are used to much like the sun a warm glow on the infrared side I'll deal with the heat is a nice bonus in the cold of winter
Halogen bulbs aren't hotter than incandescent bulbs AT ALL. They consume 2/3 for the same amount of light, and the double glass is just for cutting costs, as putting a G9 halogen bulb into an E27 incandescent is much cheaper cuz you need less gas for filling the small G9 than the big E27, E14, GU10, GU5.3, GU4 etc.
Touching a halogen bulb doesn't make it catch fire, the oil in your fingers makes them overheat and die prematurely
That’s why they tell you to use gloves when installing car headlights.
They aren't and don't tell me they last longer than incandescent light bulbs. LEDs burn out all the time, it's really frustrating when they are supposed to last years. I've had LED bulbs burn out days after first using them.
LEDs also have a strobe like, even the ones rated for dimmer switches.
Some LEDs get really hot. Turn on the light on your phone and try touching it after a minute, it burns.
I tolerate LEDs because they use less power, but that's pretty much the only way they are better.
there are these new LED bulbs that look like they have filaments in them. very cool
ok, is it possible to get the bulbs without the power-converting electronics? and then, can I reasonably wire a DC bus in the house, for those bulbs? You mention LED "strings" as being powered by a single power supply; have you heard of this being done either commercially, or by a hobbyist/experimenter? By the way, I recently heard that the Phillips brand has electronics that last a reasonably long period of time, in some cases lasting a number of years.
Honestly, I don't think they manufacture standard sized LED bulbs (too high of a chance of putting it into a normal socket and destroying it). You can get 12V vehicle bulbs and things like that. But, if you're going to wire a DC bus, you'll still want it to be fairly high voltage (unless it's a small house, though the LED loads should still be minimal). LED strings being powered by a single power supply is *extremely* common now - commercially, residentially, and with hobbyists. I have a few in my house - I even have a Philips brand string that can be controlled by an app. Frankly, I don't like app controlled devices but I wanted greater control for this particular string. In general, though, Philips products are considerably more expensive than a more straightforward string of non-variable color and you're locked into their ecosystem. Amazon is your friend in this case (though definitely not the only resource) and you will see a plethora of options at different lengths, colors, voltages, etc.
@@CircuitBread
that does make sense... that said, a bulb that had a different base (that wouldn't screw into a 120v ac socket) might be a way to allow the use of one WELL built and designed power supply (dc, for those bulbs) to power a bunch of these bulbs, in say a set of apts, and these bulbs would NOT contain any electronics, because the incoming power would be what they want. Do you think such an arrangement would save energy? -Jim (by the way, I'm also trying to hang out on your discord presence)
constant current LED drivers and their power electronics are typically 90-98% efficient these days with >95 power factor when converting electricity to DC from AC. Your house is set up for AC unless you're designing an off-grid home. The electronics aren't the problem, it's the quality of LEDs that are. Most LEDs being sold sit at 40-110 lumens / watt efficacy when up to 240 Lm/W is available.
12V LED strips are even worse. They use 3 low Lumen/watt LEDs plus a resistor that burns 30% of the DC power as heat for cheap easy regulation. If you're doing it for reliability, it's probably fine though. Not so much if you're trying to light your home efficiently.
Why we don't use single 9watt led in replacement of 1watt 10 leds? In 9watt bulb
Ah, good question. My guess would be cost, convenience, and power dissipation. Making curved LEDs is more expensive, I imagine, so they'd rather put a few flat ones in a circle. And then they can buy those individual LEDs off the shelf, further driving down development and manufacturing costs. Finally, if the LEDs are spread apart within the bulb, the power dissipation is easier than trying to figure out the power dissipation for a single, curved LED. There are probably other reasons but that's what I think.
My experience with LED home indoor lights is terrible. Color rendering is poor and I can actually see the flickering when my eyes are moving. Different brands makes very different quality. Not easy to find quality. Wasted a lot on trying. Skin tones when looking in the mirror in the bathroom is very noticeable bad, missing the red end of the spectrum. But I don’t think people are aware of it really. Until you actually see the difference. My favorite type is halogen. But I am slowly finding LED I can live with. Any tips for finding the absolute best quality LED for E27 standards?
No house has LED bulbs only. The oven counts as the incandescent bulb in the house. And most microwaves also have incandescent lighting. And some fridges do as well. Especially older models. Also they are banning incandescent and A19 halogens in 2023.
True, there's also the light bulb in the dryer that's incandescent. Incandescent does better in really hot areas and, when it's not used much, their lower efficiency doesn't matter as much.
Reminds me of my father-in-law who needed to replace lightbulbs in elevator pits (I think?). These lightbulbs are on for about 5 minutes, twice a year. At that point, is the higher manufacturing cost of LEDs worth the greater efficiency? I'd say no, but the incandescents are getting more and more difficult to find.
When he picked it up again i thought, "Has he forgotten what hes doing"? lol
Greetings from Twin Falls!
Hi neighbor!
Amazing
Yes but there is a downside to 120 volt LED bulbs. The shitty switching power supplies send copious amounts of garbage back into the AC line. This can have a number of adverse effects... one of the worse being it makes expensive high quality audio gear (powered from the same circuit) sound lworse adding grain, fuzz and nasties into the signal path. I own some rather nice sound reproduction equipment and I can certainly hear the effects of switching power supplies in the same AC line so... whenever I listen to my music I turn them off.
Yeah, in retrospect, I wish I had emphasized the difference between LED technology and the power supplies that power them. I think LED technology is great but I've been getting more and more frustrated with the low quality power supplies that are integrated into bulbs and cause problems like this and are often the point of failure.
I have some LED bulbs and the base of the bulb gets very hot. why?
That's where the electronics are that drive the LEDs, and where a lot of the losses (what generates the heat) occur. This is one reason why LEDs are better when oriented with the bulb down - with the bulb up, the heat from the electronics can slowly cook the LEDs and significantly reduce their lifespan. Unfortunately, it seems like manufacturers have been prioritizing cost over quality and so while I still maintain LEDs are the best *technology* available, I'm not as excited about the actual LED bulbs being produced anymore. They are still extremely efficient, though, in comparison to other technologies.
That is the heatsink area. Usually a thin metal base that asorbs the heat to radiate away from the bulb. Cfl bulbs are the opposite, the heat is drawn away from the base thru the actual bulb shaped tube. That's why cfl bulbs lady longer with the base down like in a table lamp.
Last longer,dang autocorrect making me misspell.
Great video there's a few strange individuals in the comments but it's the internet they exist everywhere.
😂 We are all strange in our own ways...
Um.. Yeah... "LEDs are better" because someone paid you to say that...
😂 I assure you, absolutely no one paid me to say that. Heck, I wish that were true.
There are definitely downsides to LEDs and like the comment from Infinion, I think manufacturers have not been fully utilizing the benefits of the technology due to short-sighted economic reasons. But I fully stand by the idea that LED technology (though not necessarily always its implementation) is the clear winner in MOST lighting applications.
NOT ACCORDING TO ATLEAST 10 OTHER HEALTH CHANNELS !!! LEDS DESTROY YOUR RETINAS OVER TIME!!!

Yeah, that was the general idea of what the colors represent. They could also be interpreted comparatively - yellow isn't as good as green but is better than red.
@@CircuitBread ohh 👍🏻 thanks
I don’t like led bulbs so I only use incandescent and CFL, but mostly incandescent.
I strongly prefer well-manufactured LED bulbs over incandescent but the quality of bulbs being produced recently has been very disappointing. I still use LED for energy efficiency and because they're safer from a heat creation point of view but I feel like I've been forced out of the honeymoon phase with LEDs due to the overwhelming poor quality I've dealt with. I will say, though, while I struggle to find decent bulbs, flush-mount or LED can light inserts still seem to be very good - a mixture of them being much more expensive and having more space to put higher quality driving electronics in there is my guess why.
Main reason why I prefer incandescent is because I feel it gives more realistic light. I don’t like LEDs mainly because the light doesn’t feel natural and can be too bright at times.
Does led give of any heat?
Yes, they are not 100% efficient, so LED bulbs will still create heat. However, compared to an incandescent bulb or halogen bulb, it will be significantly less. Similar to a CFL, generally.
@@CircuitBread ok thx for reply👍
Halogens burn out after 3 months It seems incandescent can last a long time but bad for energy compact florcessent lights are pretty good last 2-3 years problem is mercury spill
Led is perfect last 20 years
Yeah, I don't like the fragility and mercury of CFLs. LEDs can last 20 years but again, their initial failure rate is strangely high, but once you get past the first few months, then they should last for a few decades.
that big bulb is actually metal halide!! But it does still has mercury in it!! So do high pressure sodium bulbs.
Great video but you are overrating the toxicity of CFLs/Fluorescents.
yes they do contain mercury but its such a low amount that it is only a problem when they are stacked up in landfills.
While LEDs dont contain mercury they cannot be recycled like CFLs or FTubes can.
Good feedback, thank you! While I still prefer LEDs, I love the reminders that reality is often more nuanced than we'd like.
Compared to other technologies, this is great, but there's a giant elephant in the room that has been sitting around while we've been comparing our humanity's lighting progress to incandescent bulbs. For the past 10 years, the LED bulb efficiency available to homeowners has been stagnant thanks to industry planned obsolescence and cost. LEDs are TODAY being sold at efficacies only between 40 - 110 lumens/watt while we have access to affordable 150 Lm/W 90 CRI LEDs and 200-240 Lm/W 70 and 80 CRI LEDs under 20 cents per chip.
I'm saying this because when I do contract manufacturing designing light engines for clients, I have sourced LED chips that are 2-3x more efficient than off the shelf or even commercial specialty store ordered LED bulbs with no particular difficulty or large cost at all. Just look up Samsung's LM281B+, you can get that 200 Lm/W 80 CRI LED for less than 5 US cents a piece.
It's easier to manage the heat and the lifespan when LEDs get more efficient, but the only customers taking advantage of truly modern LEDs are those buying LEDs for high bay or agricultural lighting and that really needs to change.
I agree 100% - thank you for sharing your perspective!
Your chart needs to be updated with red for LED next to cost and yellow for lifespan. I have yet to be convinced LEDs are that much better. I have actually had regular bulbs last longer than most LEDs that I’ve owned. Just not really impressed. And I do not buy the cheapest ones either, which none are really that cheap to me. Changed most all of our lights and I saw really no difference in our electric bill.

The life expectancy of nowadays Lamp seems like a scam..
😕 Just because it says 25.000 hours Life Span, doesnt mean it will be long lasting like that..
The manufacturer just making it cheaper and better in shorter life span, so you buy it again next year.. 🤣
It definitely seems that way! Fun fact, though, LED bulbs are meant to last a long time, it's their drivers that are usually expensive. If one gets an LED with a cheap driver, the conversion of AC power (from our electrical panel) into DC power (the electricity LEDs need), is very inefficient. This heats up the driver, and makes the light die more quickly. Interesting stuff!
very little mercury in CFL
I find that LEDs are good enough. They are priced relatively affordably and so far mine have been lasting. The incandescents I was using before that were really poor quality with some unacceptably burning out in just two weeks. I seem to recall old-school incandescents lasting much longer than that decades ago, but it is what it is.
LEDs are not better. They are better in some ways and worse in others. Cheap and hateful might be a fair summary.
Haha! I do dislike the fact that some LEDs are becoming cheap, and I do also dislike the fact that the LED portion is usually good but the electronics are the weak link. Even since we posted this video I've had a more moderated view of LEDs but I'd still maintain that (barring niche applications) they're overall the best option in the lighting world. I'm not sure where "hateful" comes from, though.
@@CircuitBread 'Hateful' is the view of many people I know and many all over the world who are saying so online. Nothing against LEDS, but the choice of bright blue-rich lighting is unjustifiable and indefensible. The idea seems to be to kill the human spirit. If in doubt check out our playlist.
LEDs are better, but not for our eyes. Not going to convince you, we just have to wait a couple of years or more to see the difference. After that, traditional light sources (wolfram) will be a luxury and available only for the rich.
😮
Can not as I have seen compare LED next a 50 year old 60A19 incandescent dimming the LED will not dim equally it’s continuing in test phase .
I hate the CRI of led bulbs. Wish they would make the exactly like the incandescent ones. Leds also produce dirty electricity. People can be sensitive to the radiation.
I agree that LEDs bulbs look nothing like incandescent or halogens. They are too harsh, make everything look strange, and are known to affect your circadian rhythm. Plus, LEDs can give some people migraines. The Biden Dept of Energy has banned halogens and incandescent bulbs, though, and will even soon ban CFLs, so you won't have a choice anymore.
LED's are not better, period. Firstly, even when they say they're full spectrum, they're not. They never truly provide a pure form of light, there's always some wavelength deficiencies, causing color shifts. Secondly, the flickering aspect that makes LED's efficient, is terrible for human eyes, because it is a strobe light, even if you can't necessarily perceive it, you brain does. They literally cause headaches and eye strain. LED's are just bad tech forced on us. It's hard to notice or know it's even the cause of feeling bad, but once you realize it is and go back to normal bulbs, you realize that LED's just aren't a good technology.
I feel like they're making LEDs worse and worse, honestly. The full spectrum issue is debatable depending on usage and what your standards are. To me, in my personal usage, it's not a problem, though it could be for photographers or other people who are more sensitive to it. The flickering shouldn't happen, even at an imperceptible level, in a fully lit LED. However, I recently bought about 25 LED bulbs (name brand, expensive ones) and, even without any dimming, about 10 of them (of 25!) perceptibly flicker on occasion. I've been wondering recently if we need to do a response/rebuttal/update to our own video. Where I think we would disagree is that I think the fundamental technology is still good, but that implementation is lacking.
@@CircuitBread I always notice the flicker, not necessarily directly from the bulb or looking at the room, but if I wave my hand across my face, I can see the strobe effect in the movement. That's what causes eye strain without realizing it, because it actually fatigues your eyes. When you move a hand across your face quickly, it should be a blur. Instead it's easier to see detail as it moves, which sounds like a positive, but it's fatiguing.
Since our eyes saccade constantly, even when we're just staring at something not moving, the flickering still causes fatigue, because for some portion of your eye saccades, you get only a partial or no image at all for the saccade to work with, without realizing it. I'm sure you remember the old Jurassic Park concept that a T-Rex can't see anything if it doesn't move....and that is actually how our eyes work at the photo receptor level.
If we didn't saccade, a still image would be kind of the same as seeing no image, or more like the flash of an image, kind of like when you look at something bright and close your eyes and you can still kind of see a residual outline image of what it was. We see by changes, and saccades provide that. They slightly adjust the position of our eyes so that the image we're viewing, even when sitting still, hits a different photo receptor, which is what allows us to actually perceive things. That's what those still image illusions you see online, exploit to create their effects.
Our eyes have been said to be able to perceive as much as 2,000hz. Of course, that doesn't mean anything less than that will be agonizing for our eyes, or even directly noticeable. LED's are tricky like that, because you just don't realize they're a problem until you do. Even people who think they're fine and not bothered by it, just don't realize it because it's soo subtle. But once you go back to normal lighting, you do notice the difference was greater than you realized. That's part of the trick. You can go from Incandescent to LED and not notice a huge difference, but go back to Incandescent from LED, and it's a noticeable difference.
I think they're making a lot of things worse these days too though, LED's included. You can see widely varying wattages and weights. I've had bulbs that were the same wattage, but one much more heavy, indicating either better cooling or beefier components, or maybe even heavier due to using less refined components. I've also seen very lightweight bulbs that have twice the lumens at the same wattage or even lower wattage. What that tells me is they're pushing the hardware too much, which will cause faster failure rates and bad performance. So far, not a single LED bulb I've used, has ever lasted the claimed bulb life. And I've used quite a few, even splurged on more expensive ones, and even taken considerations of if I'm using them in a place where they are more likely to overheat or not.
I still use LED's, but only in light sources I intend to use briefly, like a closet, or for outdoor lights. Reading and living room and kitchen and office lights, I use Incandescent. LED's are especially worse for office lights, because a computer screen and LED bulbs can have competing color temperatures and refresh rates, which only magnifies the problem.
@@peoplez129 Where are you getting your incandescents?
Candles?
Man... I wish I had included candles in the comparison... opportunity lost.
What
leds are not healthy. Didnt you know
very nitch 👍
Compact fluorescent bulbs never gave me any problems. Just like incandescent, they're hard to find. Most are LED now. That created some problems. You need clean, no spike or brownout, electricity to run these as most are dimmable. A refrigerator cuts on, heater kicks in, a washing machine is running. All these things affect it. Gives me headaches. Only the non-dimmable garage door opener type work well for me. Of course not good on a dimmer as you would use your now standard LED. I would rate the compact fluorescent yellow. I've had quite a few crack for no known reason.
Don’t LED age you faster!
I think the author of this video meant to write LEDs and not LED's. But hey, nowadays even Brits do that.
That would be correct! images.app.goo.gl/szudV6ii8zZZVHqS8
My only disagreement with that image is the statement about being good at math...

Reading. ??
Bro you gotta edit out the speaking slipups
not enough light,even in home depot they dont know about lighting.
Mercury vapor?? As in Hg? Ew...
No they are not illegal in eu
LED's are the best!
Led is the worst light on the planet.
Read, The invisible rainbow by Arthur Firstenburg.
LED light bulbs has 95% more energy efficient, 100,000 hours lifespan, highest light quality, easiest to use, no mercury, best on-off durability, and greatest physical durability, but the initial cost is moderate.
Excellent video! Your points were well demonstrated and articulated.
However, let's not forget the negative health implications of LED bulbs such as damaging your body, specifically degenerating eye health.
Also, red light is necessary for promoting a healthy circadian rhythm.
These light bulbs are dangerous beyond belief and I believe if everyone knew this, we'd be stopping this nonsense of making incandescent (the best) illegal.
Led can come in red
@@8h8_illustrates yes! That's slightly better but LED bulbs also have a high flicker rate which is unhealthy. It can trigger migraines and worsen eye conditions.
And as for it being "better for the environment"... Is it really with the big hunk of plastic at the base of every bulb?
@@MeganGarzaWellness is metal mining better? Thats what the alternative mounting requires.
@@8h8_illustrates there's not much of a solution I can think of. I would like to have these answers but unfortunately I don't.
Most things that humans have done since the industrial revolution has been damaging to the earth. We're on a collision course with the downfall. When will it happen? Idk but it will one day due to the lack concern of consequences for our actions.
They aren't
