- Why are LEDs so much more efficient than incandescent light bulbs? Do LEDs have disadvantages?
These are some of the questions I answer in this video about light bulbs. I also test the claimed wattage and find some anomalies...

4:30, it's amazing you mention this. When I was a kid my parents switched to Flourescent Lighting over Incandescent, when we tried to eat dinner I had to excuse myself because the food looked so unappetizing after the hue change. Everyone made a big deal out of me excusing myself and was talking about me like it was weird and I was being rediculous, good to see I had a legitimate point.
I have never liked fluorescent lights since I was a little kid but I have to tell you I also hate the LEDs they make me feel sick and they make everything look flat and weird almost like a Twilight Zone when I'm outside and they're coming off of buildings and street lights..... I am proud to say I only have incandescent in my home .
@@gardensofthegods your power bill must be insane
Incandescent light is better than led and florescent lights health-wise.
The early flourescent lights were limited in their watts and their color index. In the newer ones you can get much higher light output and much better color. You can even get daylight bulbs now.
The Sun is the best lamp.
I am very happy now. Thank you all :) Lots of comments and likes already even though this video is about something as trivial as light bulbs. But interesting science is hiding in just about everything...
I will read all of your comments now and try to answer questions.

Maybe add sodium light bulbs aswell
Sure, but I prefer the cosiness of warm white when I'm eating :)
High kelvin seems too clinical and cold for my taste and home. Like visting the dentist... Thanks for the input.
But it's also worth mentioning, that the light emitters have different spectroscopy image:

Could you publish your comparison chart?
Thank you so much. I've been looking for a vid such as this for quite some time now. As it's now evident, if you want true colors, you'll have to buy a LED that has a much lower lifetime expectancy than the ~80 lamps. From 15.000 down to 2000, just as long as regular oldschool bulbs.
Fumas12 Thanks for watching! Let's see how the market develops in the coming years. At the moment it's difficult/impossible to find LEDs for household lighting with very high CRI...
I love those antique LED bulbs so much, that aesthetic.
Diet idea: Replace the bulb in the fridge with an LED with
Ruben Kelevra Why?
@@nicholaslandolina just to make sure to watch the video before you start to ask questions.
Replace it with a street light
@@nicholaslandolina it will make the food look less appealing.
*laughs in >95 CRI*
In winter the incandescent bulbs have an efficiency of 100%. The heat is more than welcome then.
True, except that electric heat is more expensive than natural gas. If you heat your house with electricity, than it makes no difference which type of bulbs you use in the winter.
That's why CFL and LED lights don't make sense in Canada. They are only helpful for 2 months or 1 week when room temperature hits 30 °C.
louis tournas They are helpful more than 2 months. It's not just when the air conditioner is on that they help. They will reduce your power bill in all months where the furnace isn't being used. Unless you live on Elsmere Island :-)
My3dviews Furnace? Not many people have one of those diesel burning furnaces. We use electric heaters. Big businesses and shopping locations probably use natural gas.
Hydroelectric power!
louis tournas Where I live, we mostly have natural gas furnaces. www.lennox.com/products/heating-cooling/furnaces/ml180
dont worry, those outdated bulbs will survive production a long time here in the third world!
thats what i was going to say about, second and third world countries are still using and will be using them for a long long time.
That's just how everything goes. We're shutting down coal power plants, because they aren't environmental friendly enough, but we ship all the machinery to third world countries so they can run a coal power plant for many years. A recent one that shut down near me had all the machinery shipped to Nigeria.
But the strange thing is that LED-bulbs are almost as cheap as incandescent bulbs on eBay nowadays, and you'll save a lot of money on power by using LED over incandescent.
+PROTOCOL Some of those cheap ebay LED bulbs don't last long enough for the cost. Cheap junk isn't always low cost. I had a couple LED bulbs that didn't make it to their first hour.
+My3dviews Most of our house is using cheap frosted/matte warm white LEDs from eBay, and they've lasted for about 4 years now. Tried several types until I found one that has a incandescent-like color that doesn't flicker. Can't remember the price on them, but I believe I paid $2 each.
Thank you for posting an accurate and informative video that covers so many aspects..LED lamps are fast becoming available in a variety of colour temperatures, but a full SED curve will always make them slightly different from conventional lamps. You may not have fully realized that prepared food is dyed to look appetizing. No doubt as LEDs become more common place the food manufacturers will start to use different dyes.
Something else to consider is that medications have dyes in them that look a different color under fluorescent, incandescent, and LED bulbs and it has caused me a little confusion thinking I was given the wrong prescription when I got home looking at my prescription under my new LED bulbs. I was expecting a yellow coloration to the tablets and when I got home they were all white so I thought they had given me the wrong dosage but then at the drugstore it was all back to the right color.
🤪
thank you. I was totally ignorant about CRI. this gave me good idea about purchasing LED lights
My incandescent bulbs cost me nothing to operate. I ran an extension cord from my neighbors house.
You can only run 22 60-watt bulbs before you begin to fry the extention cord though, keep that in mind 😂
Viewers- if you're ever buying LED bulbs for in your home, be sure to buy "warm" white and not "cold" white. Cold gives that fake looking effect like Brainiac showed with the meat. I enjoy mine.
Ikeas ones are also quite warm, but may cost a bit more
Cold white looks terrible in most applications, short of headlights, and interior cabinet or case lighting. It strains the eyes and makes you look like a vampire.
***** 'White light', that is either on the side of cool, or on the side of warm. Natural white is actually very slightly on the side of warm, like sunlight. I am not talking about that yellow orange light like old incandescent bulbs :) Although, that lighting will compliment your complexion.
Philips Hue LED bulbs costs a lot, but they're the best I've seen with a high CRI index and adjustable color temperature.
I slightly disagree :) I'm sitting in a room lit with 4200k CFL's and I really enjoy it: They seem "cold" compared to incandescent or even regular CFL's and slightly warm but close to sunlight with a small shift towards pink during daylight. I have 5500k "photo" type 85W CFL's in my garage and I also like the color there.
Very, very informative, thank you
+Sword depends on the source , if you use a cheap led it will look like crap , but if you buy a good high quality one you will take your words back .
I've worked in the sustainability & energy efficiency sector. I get many questions from clients & people asking if they should swap their halogen or filament bulbs for LEDs or CFLs. The answer is... it depends on how often & how long you use the light.
If its a light that you use often, say >3 hours a day, then the cost-benefit justifies it. It will pay off in a less than a year or two. But if it's a light in the laundry room, storage room, or a vacant room that you only use once or twice a week for less than 15 minutes... then it's better to leave it be & only replace it when it goes. I have an old filament bulb in my laundry room that's been there before the phaseout (filament bulbs were replaced with halogen technology) in 2008.
we went LED through out, in the low uses rooms more cause daylight leds are so bright and pure a white and we can use higher output bubs than was safe when they were incandescent
I changed my CFLs just beacause of the annoying warming up time, specially if you are just going to be there for 5 minutes but I still have an incandescent one in the staircase that the previous owner left and I wonder how many 100 year old bulbs are we going to have in the future.
I just found out how bad LEDs are for our health. The ban was a terrible idea.
When I built The House of Steel almost 20 years ago, I installed mostly halogens in the high use areas and incandescents in the low use areas. LEDs were far too expensive at that time. The high voltage halogens aren't particularly long-lived, though the low voltage/low wattage ones are still going strong. I replaced three of the 50W sealed downlights with the highest output LEDs available about three years ago. The LEDs were quite dim (and therefore dangerous; they light my kitchen bench) and the first failed after three months so I returned to using sealed halogens. The incandescents lasted longer than 10 years and were definitely the cheapest option.
The short lifespan of the LEDs makes them the most expensive by far. Also the highest energy consumption when you realise that their cost is a function of how much embodied energy they represent. The high voltage 200W linear halogens have a lifespan of ~3-12 months. The sealed dichroics about 12 months. All of the supposedly energy-saving bulbs cost me more than the old incandescent bulbs did. CFLs are lasting quite well in the low use areas, but the ones in my home office only last about the same as halogens, 6-12 months. Also the 12 volt devices consume transformers. They rarely last longer than 2 years.
2 years later: I would advise traditional incandescent bulbs for your nightstand or reading light, also for kitchen. LED lighting is not good for your eyes.

Thank you for this video. It was interesting to learn about the different bulb type, ratings and especially the color output.
Wow, first video I saw on your channel and I already subbed! Very informative and thorough. I can say that while this video was educational, it was also not a yawn-fest and was very much a joy to watch. Thank you for your content, you're an excellent cameraman and commentator, I look forward to seeing more of your channel.
Great you have mentioned issues with LEDs! The interesting aspect would be to analyze LED impact on human eyesight...
It depends on what wavelengths you're sensitive to. I have no problem with cool white LEDs or CLFs, but I've got family members for whom cool white is a migraine trigger, so I try to make sure all the lights are warm white. A particular pet peeve of mine is when I see LED lights (especially Christmas lights) that are only half-wave rectified (by nature of being a diode), which subsequently give off a 60Hz flicker. You can stick a bunch of LEDs in series and use the collective resistance in place of a dropper, but you're only using half the wave while blocking reverse current on the other half (they burn out quicker that way too). That's another migraine trigger for some people. Full wave rectified, with a smoothing capacitor, is far easier on the eyes.
I thought you were in a biohazard ppe lmao not a clean suit at the first glance
@thegrandfinale2 Bright visible light doesn't make you go blind. High intensify UV light does. Such as, staring at the sun, or a welding arc without a visor. But staring at a tablet isn't going to do anything to your eyes.
@thegrandfinale2 The old computer nerds who were looking at all those green and amber CRTs 30+ years ago haven't gone blind yet.
@thegrandfinale2 No, but they did have considerable eye strain. It's no different than sitting in a dark room with a desk lamp. You're not getting any more luminous by using a tablet instead of a desk lamp.
Very interesting video about light bulbs! I have moved into my own apartment a year ago and needed to replace a bunch of lights and I got LED's with the most "daylight" feel. I also bought a "Bug repelling" light bulb and it says the exact same thing on the back. lol

Great video! As a typical mono-linguistic American, the quick lesson in proper pronunciation of Rullepølse was my favorite part. I needed that, thank you.
The incandescent bulb may not be dead yet as MIT found a way to greatly improve their efficiency with nanophotonics.
These also may be more environmentally friendly to manufacture than CFLs and LEDs.
For christ sake just google it. You can't expect citation for all comments.
Yep I heard the same thing and I just googled it is true.
Ah, the internet. I know it was posted a year ago. But if you'd asked nicely if this person could provide a link, that would have been a decent way to go about it. Just saying "citation or its a lie" makes you look like a royal asshole and nobody will want to provide anything for you. Seeing this comment is like the internet version of stepping in dog shit.
I'm still waiting for this :( @ge @phillips??
Well all I use is incandescent because I never liked fluorescent , I never liked the compact ones either and I absolutely abhor the LED which make me feel ill .
A factor a lot of people miss is that in cold climates, the "wasted" heat energy isn't really waste. In fact, if you heat via resistive electric (which a TON of people do) virtually ALL the "wasted" energy is put to use exactly as efficiently as the furnace or baseboards.
The mitigating factors are when it's warm enough that you don't need heat, in fact you pay double the penalty if it's hot enough and you have AC running (lightbulb uses 100W to make light +99 watts of heat, ac probably uses 60+ watt's to remove that heat from the house)
overall though, in many climate's LED's aren't that much better in the long run (we heat 8-9 month's of the year where i live). not to mention how much more waste goes into the landfill (sure led's say they'll last 25 years....which mean's noone you've heard of has ever had to replace a led bulb yea?) Glass and metal are recyclable, or at least they are inert and won't harm the environment. I'm not so sure the same could be said of the plastics and electrical components that go into led's. Sometime's I feel we've forgotten many aspects of pollution with all talk being focused on AGW
Was about to write something similar. Here in the northern Europe winters are long and dark, time you need to use lights the most. Any savings from lighting during those times is directly moved to heating cost. Only savings you get are during the summers which are very short and bright so you barely use any lights anyway but still the same laws hit us and banned incandescent bulbs.
Even if you were living in optimal conditions and got proper savings from leds it's still a piss in a ocean when compared to other polluting things. If you want to save the earth then there are loads of better things to do than go after incandescent bulbs.
And Denmark itself is in a cold region... Their summers average 60 outside. So yeah.
You forgot to mention the cumulative of mercury vapor to produce these incandescent bulbs in the factories and landfills.
interesting comment, a brief look into it though. It seems that the mercury incandescent bulbs contribute is based solely on the fact they use more energy, and fossil fuel powered electrical plants emit mercury.
so..not really. We were talking of incandescent bulb use in climate's where it's cold more of the year then it's warm. Since cfl\led isn't really much more efficient when your heating you home via electricity 3\4 of the year, the "extra" mercury put out by powerplants is a moot point.
Ben Le
Also, what's the deal about mercury vapor? Another greenhouse gas?
Great video mate, very thorough and informative.
There! So now I know a little more about lightbulbs than I did before. It was a pleasure to watch and to listen to this video.
I appreciate the explanation when it comes to the "flickering" of cheaper LEDs...
I had bought some night-lights at the Dollar Store that have each have a Blue LED in them.
They look fine to the naked eye, but when I look at them through the view-finder of the camera on my phone,
they flicker like a strobe light.
_Always_ wondered why until now!
In the life of that piggy 2016-2016

El esta bien, en el video le preguntaron estas ¿Estas bien? Y el se movió.
Amazing comparison. Thanks for uploading!
i learn more from this man in 11 minutes than a whole year of my schools science curriculum
Ironically, one type of bulb that managed to skirt around these issues so far is "Rough Surface", basically a more sturdier version of incandescent bulbs as they are mostly used in places that may be prone to shock or other rough situations. I picked up some from Dollar Tree a while back (under the Sunbeam name), yet they don't last as long as I hoped, a few burned out within a few days.
6 year so far on my LEDs.
3:51 love this tiny bit of humor! Kudos mate, thx! Ofc I did thumbs up it :)
Halogens became popular in the US in the late 1990s, about when my husband and I got our first apartment. We got a halogen lamp for very cheap, and we were excited to see what energy savings we would get since we were paying for our own electricity. One thing we noticed is that the halogen bulb got very very hot! So hot that it was burning the floating dust in the air and we could see smoke coming off of it, sometimes. One day it knocked over and caught fire! It was a good thing that we were home when it happened. Ever since then I won't use halogen. I am all about saving money but the incandescents will always be my favorite :). Thank you for this amazing video!
Yeah, the person the remodeled my house put in halogen under cabinet lights. OUCH OUCH OUCH, you burn your hand trying to turn them off. I replace them with some 96+ CRI LED light that use less then 1/10th the energy and I can leave them on all day and night, which I did one to test, and it never got hot. They have a LOT more lumens too. It the expensive GE lights. I got some Hyperkions for the spot lights over the cooking area / island since I want high CRI and safe for over a cooking area.
Nice work man, we have a lot to learn from your videos.
6:55 the NorthStar Antique Clear bulb has a very nice Lumen/Watt rating
Although the LEDs are very efficient and I use them to light the house, I have to say that I like the incandescent lights better. Interesting thing is that most black fabrics have a slight red tint to them, but under incandescent lighting they look dark red rather than black. Under LED lighting the red color is almost not there, and normal reds look faded. Under incandescent lighting I can easily tell certain black fabrics apart by how red they are. Black plastics just stay black though without any care what lighting they are under. I've got some form of light over-sensitivity. I just thought it is weird and wanted to know if anyone else noticed any of this.
Brainiac75, we’ll done. Great original work, clear video, good voice clarity, nice background music. And convincing presentation of relevant facts. I’ve spent countless hours in Home Depot staring at all these lamps, looking it all up in Wikipedia back home. You’ve clarified all my unanswered questions and given even more thought provoking information. Keep up the good work!

Excellent information! Useful stuff to show my family... I was an Electronics Engineer repairing PC, Laptops, etc., and trying to explain to my family what the differing bulb lights actually used was a nightmare for them, but not this clip! Great.
this is a good, clear video. thanks man!
Hey Brainiac75 - We are not seeing voltage and I suspect that your source was not a perfect 230V - This may be the reason why all incandescent lights were showing less power than advertised and under higher drain (400W) difference was even bigger due to higher voltage drop. LED lights with built-in power supplies (not a capacitor dropper ones that flicker) are voltage independent, they will often run from 100V or below up to their "popping" voltage drawing exactly the same power :) They even run on DC.
To show how important is voltage drop lets take my 3 kW kettle that I use: It only draws around 2 kW as I'm on the very end of power line and I receive around 220V which drops to 190-195V measured on a socket in the kitchen when I turn on my kettle. That's 2/3 of rated power :)
Was about to say the same thing :)
Thanks for the input. That actually could be the case in my house too. The wattmeter probably isn't extremely accurate either - but the readings for the bulbs should still be relative comparable.
If the voltage is 220VAC the the frequency is 50Hz and that doesn't help with flicker. 117VAC and 60Hz is better because the peak voltage is lower and frequency 17% higher.
Voltage drop, BS!
I remember when my house has a heat bulb in the bathroom for when you got out of the shower, it was so nice as warm😊
excellent report
I like the little humor thrown in every now and then
👌👌👌
Funny thing is you can sell indescant bulps if you sell them as heating unit, not light source ;) Funny how EU regulation goes sometimes... Theres engineer in Germany that does this...
Hehe, yes. Predicting the imagination and creativity of millions of people is tricky ;)
As a heater they are decently efficient.
I was working on a house recently that was completely outfitted by LED bulbs that were on sale in town. I was feeling nauseous and I couldn't figure it out, I had to walk outside to overcome it, it was painful being inside with the lights on! This completely explains why! My eyes were straining terribly under the cheap LED light, now I know what to look for and recommend if anyone is considering replacing their incandescent or fluorescent bulbs with LED.
Actually we switched over the LEDs and hated it, so our house is full of incandescent and fluorescent bulbs again
Very interesting video, thank you!
Brainiac! I definitely enjoy your videos and I always have, thank you for making such great videos.
Maybe I am imagining this, but I literally cannot see well with LED or Flourescent lights. It's bright, but I can't see. It's the strangest experience. I so miss incandescent lightbulbs.
What is the lumen rating of the LED/flouro lights you're using? That's actually what's important. I notice many websites & videos that explain about switching to LED/flouro fail to mention this. The result is many folks end up getting LED/flouro lights that produce a lower light intensity than the filament bulbs they want to replace.
For instance, if you want to swap a 60W incandescent, get an LED or CFL that produces 800-1000 lumens.
It could also be the color temp.
LED AND FLUORESCENT lights do strobe. Most people don’t notice it but some do. I have read that they can cause seizures in epileptics! If they can do that they could affect some people’s vision.
Eclectic Monstrosity It is not your imagination, I can't see with them either and I refuse to buy them . I am considering getting kerosene lamps . I know the lighting from it won't be as good as I am used to but at least I won't be paying for absolute crap and it will be one less thing using electricity.
@@royrice8597 That exact reason is why I am an EDC flashlight snob. The cheap torches at the chain store may seem bright, but between the blue/purple/green hue, low CRI, and pulsing light you might as well be colorblind when using them.
I really want one of those 40W LEDs now... I don't care how impractical it is, I want one.
Hehe, I also just had to buy it when I found it. Big size still counts :D
Brainiac75 I know right :)
get some youll save a lot of power in the long run.
Nigel Russell Compared to what exactly?
A 40W incandescent vs a 40W LED is still 40W of power...
The only reason I wanted the 40W LED specifically is for large room/outdoor lighting.
a 40watt incadecent bulb will not out put as much light as a 40w led bulb. as much of the power is converted to heat.
Thank you for illuminating us on light bulbs.
Bryce and I enjoyed this video! We learned a lot!

What a fantastic video, you have gained a subscriber, thank you and greetings from Mexico!
Mexico! That's awesome - welcome aboard and greetings back from Denmark :) Are incandescents banned in Mexico or do you still have the freedom of choosing yourself?
Hi there! Well, here in Mexico most incandescent has been removed from the metropolis, you may still find them in province but never in a supermarket, legally they are yet to be banned. Interestingly enough, you can still find a lot of incandescent with opaque|frosted bulbs, but people dont really buy them anymore and usually prefer halogen ones since LEDs here are about 20x as expensive as a regular and they save important amounts of energy. The industry is slow to change, mostly due cost of products.
Richard Frank Interesting. I wouldn't buy LEDs either if they were 20x as expensive as halogens... In Denmark there's no real difference between the price of incandescent decoration bulbs and similar LEDs. But I am aware that we overpay heavily for the incandescent decoration bulbs :)
I actually went to the local market to take a few pictures on the lightbulbs commonly found here for you to see, probably as common as it gets on any shelf in the world:

The incandescent decoration bulbs can only be purchased on stores focused only in lightning/decór, and yes, in here they cost as much as a LED indeed, so people either buy halogen or the spiral saving ones, unfortunately, the market of spiral energy-saver bulbs was overflooded with really bad quality products from china, some give as low as 500 hours before failing, in fact the government had to exert temporary bans on these until G&E and Osram (along third parties) could switch production lines locally or import, its kind of easy to tell which one is a knock off or a good one, starting with price, we REALLY dislike chinese produce since for years they have been sending really really REALLY bad products here, some have even been found to contain lead or foreign objects or having its circuits (LEDs) melt and cause a fire. (this is not even only related to tis industry, foods and many other items have been found with issues, specially batteries and ballasts bursting into flames suddenly (explody mcexplodface), when the Safety commission found out they blew a gasket and shut down any lightbulbs's import of any kind from china for almost 2 years (this was 3 years ago). As a result, the prices skyrocketed which delayed the transition greatly, as of now its been normalized but the issue still persist.
Fortunately, national production quality have been improving to international levels since the turn of the millennium and nationals are found to be competitive with US brands, but people are waiting for prices to drop, specially in the automotive industry which im quite interested, as Halogen's are being displaced by Xenon and LEDs in a massive take over.
Richard Frank Thanks for sharing. Now I know a little more about the daily life in Mexico :)
Not surprised that you also have trouble with very cheap Chinese import... The bulbs look very common. Only thing I noticed as special is the 127 volts. That's not common.
Fantastic thanks for the vid I have notced yellowing on most things in my house after installing LED lights, I did not know about the Colour Rating Index (CRI) and how this effects your surrounding, thanks so much I will keep this in mind when I buy future bulbs.
Thankyou, it was enjoyable and educative!
Incandescent is still available as heat lamps and automotive use. Halogen bulbs are incandescent with a sensitivity to oils touching the bulb. Still used in some construction lights, but slowly changing to LED. Kitchen circle lights are better as a plug & play LED version. Those are hard to bypass the ballast.
Yeah, only issue is that everywhere is getting rid of fluorescent lights which is dumb. Our house is still full of incandescent bulbs lol
Why are they sensitive to oils?
Super fedt indhold Braniac! Keep it up :)
Tak - much more to come :D
Jeg er enig med Jensen. Videoens emne er efter min mening vigtigt og relevant, og noget de fleste vil have stor gavn af at lære mere om.
Alt for mange køber desværre bare de samme pærer de altid har købt, uden at tænke over energiforbrug eller levetid.
Levetiden har jeg oplevet som et godt argument, når jeg har forsøgt at overbevise folk om at købe mere energieffektiv belysning. "Jamen de pærer er jo fem gange dyrere", har jeg mange gange hørt. Men når jeg så forklarer at de holder 10-30 gange længere og derfor i længden er meget billigere, bliver dem jeg taler med ofte overbevist, og begynder alvorligt at kigge på mere energieffektive pærer. For hvis en pære koster 5 gange så meget men holder 30 gange længere, er dens pris - uanset energiforbrug - kun 1/6 i forhold til levetiden.
Det sidste kom du desværre ikke så meget ind på i videoen her. Men det var måske værd at tage op i en fremtidig video? Folk elsker jo, hvis de kan spare penge.
I find this video to be quite informative and well presented It is worth the time watching it
Excellent video!
Thanks! Now I know what all those cryptic symbols on bulb packages mean so I can now make an informed decision when I buy my bulbs, especially the colour rating index- since as an old person I like the "incandescent look" of warmer light it's more comforting to me :) I'm going to subscribe :)

Hehe, you're welcome = 'Velbekomme' in Danish :D
Brainiac75 [Google translate] tak. :)
...is that correct? :)
Victor Tran Yes! 'Tak' is Danish for thank you.
Brainiac75 Yay! :D
did you ever think about making a comparision of differenta type of LEDs?
Very nice!
Loved this video, Thank You..
I personally like halogen bulbs for my workshop. They produce a nice white color and are very bright.
They are NOT white, they are very warm "yelloish". But if you like those best, its up to you.
It's hard to find LED's in the 7000k - 8000k range, except for some auto interiour bulb replacements on ebay. I like that color rendition best. It's white to slightly blue. And looks really good for my Aquariums.
I'll go with those any day instead of LEDs which I hate and I can't stand the compact discs either.... in my home I only use
incanndescent.... I don't care if it cost me more .
My incandescent amber light bulbs that are low wattage and my hot pink low-wattage light bulbs or what I have on in my home in the evening and it has a nice soft glow.... I bought hot pink LED and also Amber LED and they were horrible flat cold weird electronic light that does not have any warmth or beauty
@@gardensofthegods There are a lot of really good LEDs outside, but they are not cheap at all.
But there is nothing wrong with halogen either. Nice that everyone can choose what he wants. At least until the lower wattage are also gone
@@PM-wt3ye some of us can tell the difference between the LEDs they... are electronic.... some people those of us who have had brain damage in the past and other neurological problems can't seem to be able to deal with them . Wow I thought I was fine and then the onslaught from the LEDs out there has created a lot of problems.... as I said I am not the only one complaining about it . A couple months ago I found a website where people in Europe are trying to get them banned .
04:30 Which one looks the most delicious? The word "delicious" has no place in a sentence describing that sliced culinary atrocity, regardless of the lighting.
I learned a thing!!! I learned a LOT of things!!! You got another subscriber, too. Thank you.
Great video! Very interesting.
Another interesting point to mention, LED lights come with some negative health effects as compared to the older alternatives. Look it up!
1:41 Actually, I was told it was a mix of Tungsten and Osmium - which is how the OSRAM company (a product of which is seen at 9:20) got its name - OSmium and WolfRAM. They had a factory in my hometown until a few years ago, really liked them, even named a bridge of our inner-city railroad after them.
I could see osmium being useful. It's melting point might be a bit lower (3400K instead of 3695K) but it's also a worse conductor (by about 42%), meaning it should help getting the resistance of the wire up, making heating it up easier.
very thorough
love this. especially love when you try to teach us to pronounce whatever that food is
0 dislikes yet, love seeing that
Rullepölse.. sounds funnny :D
Sausage
always wondered what ''CRI'' meant, tk u for clearing that up.
it is to my belief that the reason the incandescent bulb is still around is because of its high output to keeping the food more stable and fresh .
awsome vlog !!
Wholesome lightbulb video in my recommendations
Great video! FYI though, the CRI video test with the meat was likely confounded by white balance differences - to be a fair test, the three would need to be white balanced to their respective sources individually, ideally using a quality white balance reference card (that’s the problem with low CRI lights, even when properly white balances, differences in colt reproduction exist because of holes in the emitted spectrum)
I changed most of the bulb in my house to LED, and ever since I started to feel more tired.
Probably more work than you have done in a while.
I found a website last year and you're up where they are trying to outlaw those horrible LED lights because of how bad they are for people and personally I absolutely hate them and only have and canndescent in my home
@@valerierodger7700 Well, it really depends on which LED light you buy. Incandescent lights usually have a color temperature of 2700K, which doesn't excite your sleep hormones too much. Most LED lights are way above 3000K, but lower options are avaiable.
@@Minecraftminer3000 Yea better off getting warmer colors
I like this video very much!
How can you not press the like button with such a lovely person asking so nicely :)
Certain LED’s also cause wireless interference. I was unable to listen to the FM radio with the lights on (4 LED lights made by FEIT electric) as soon as the lights were turned off, radio signal was great. I didn’t test further, but I highly doubt they only cause interference on the 87.9-107.9 MHZ range, which in itself isn’t good, for electronics or your health.
Also the bulbs ran really hot (about 70° C / 160° F), although they are rated for only 21.5 watts.
It's non ionizing radiation, so it really can't damage your cells at a molecular level. The 4G data being transmitted is more potent than any LED circuit driver. Plus the driver only consists of a full bridge rectifier, transformer, capacitor, and voltage regulator
@@danieldyman7196 That doesn't mean it's ok to transmit a lot of noise at those frequencies. Though a
bulbs conforming to all the specifications really shouldn't do that and I think most of them don't. Also a 100MHz is a very high frequency that I don't think any switching converter uses.
Yes, and that interference also makes them unsuitable for many garage door openers. I had to tell several neighbours about this, when their openers suddenly started acting in seemingly unpredictable fashion.
Anyone else remember back in the day melting stuff on lightbulbs?
Think I'm a little blind now lol
Hahaha when I was a kid, I thought it would be cool to make my room all crazy looking by putting bits of coloured cellophane around my light fixture. It looked really awesome. For a couple of minutes. Then yeah... The melting thing happened.
Yes. When I was a kid, I put Crayons on the bulbs.
@@gordselectronicshobby3853 me too!
Great video! You just earned a new subscriber.
Thank you for taking the time to make this video, it was very informative. (3200 lumens in the living room... I laughed a lot... XD)
I remember stocking up on incandescents when they banned them.cause they were cheap. bought out a stores supply. still using em today
John Johnson as did I 😁💡
They were super cheap here as well, so I bought literally hundreds for very cheap. I decided to upgrade to LED anyway (which I think was worth it) and sold off the incandescent ones for over market price because at that point they weren't in store anymore lol
I still use them and you can still buy them but those of us who bought them early saved money
wow with this video i've learned more than in my chemistry class
I think you're very funny but I love how well you explain everything. Being funny makes it so easy to understand. Anyway, inconsistent OR LED . . . WHO CARES? Both are better than the candles we had to use not too long ago!
good work
for filming to flicker on the led you could have recorded slomo.I recorded a led bulb in slomo at 240fps with a iphone6+ and it shows the flicker.
Those old bulbs didn't use a capacitor or a full bridge rectifier. Modern LED's don't have flicker
@@danieldyman7196 Lots of them still do have flicker. I had to buy LEDs specifically sold with a flicker-free design when taking product images. The other LED bulbs sold all had flicker and cause banding in images or videos.
Here in Germany, halogen bulbs habe been banned from production a few days ago. This means that only the leftover bulbs are allowed to be sold, and if they are sold out, halogen bulbs are gone.
Cool video, thank you.
Interesting video.
I think you should still allow people to use their bulb of choice, some things can't beat the look of a incandescent bulb. Also LEDs sometimes suffer in colder climates along with CFL in that they take longer to get to full brightness.
Exactly. I hate when stupid governments dictate what lightbulbs folks should use.
@@Ignisan_66 "Yeah man, governments and their laws, they limit our freedom for no reason! I want my own ambulance strobe lights for example, but they dont let me for some reason. And what if I want a different color for traffic lights? I think they all should be green, it is a beautiful color. Also I hate cops, we should remove them entirely. They are the embodiment of the oppression after all!"
I've been using LED lights in my house for almost 2 years, all I can say my eyes are tired... headaches....
Yup...i'm switching back to Neons, im not going to sacrifice my health for cheaper electric bills......
Eko Heriyanto you mean those little compact flouresent lights full of Mercury, that if it gets broke inside you should call hazmat to come clean house because the Mercury vapor spreads throughout the house.
are you using cool LED lights? if so you might want to consider getting the warm vareity
Get the LED Warm white ones... they look Cozy
What about Greta Thunberg's needs? Fuck your eyes, those babies belong to her
@Blind Freddy Leds are flickering, and also blue spectrum light, almost no red light, it doesnt matter what color light you have, warm or cold. I was pioneer in led lights, now Im using classic bulb in my bedroom and workrooms, its a lot healthier, its alot more easy to concentrate and do tiny works under classic bulb
Damn, you killed the pig 5:50, just like in *_1987 PREDATOR_* 😂😂😂
good comparison
