12:29 is what you looking for
Holy fuck thank you
Thx
not at all what i was looking for
Thanks man
Thanks mate.
broo I used to watch this when I was young. I didn’t understand what was going on and was just interested in light bulbs. The nostalgia hits me 😢
The fluorescent is by far the best with the closest 365nm range for UV glow and very little visible (UVB) spill light.
The LED UV bulb is no where near as good as the fluorescent and the incandescents are so bad and hot that I don't even know why they make them any more.
Kinda surprised you don't have a mercury vapor blacklight in this vid...
where does mercury vapor fall in to this category? also Parrot175, have you dabbled with Actinic. I'm sure many aquarium enthusiasts would like to know! (me included)
You can get BLB mercury lamps with a woods glass outer envelope that make one of (if not) the best blacklight effects. they're available both in self ballasted and externally ballasted variants ranging from 100 to 1000 watts depending on what you want to use them for.
The Mercury BLB lamps are used in concerts and some theater performances. They can't fit in a normal 120v socket though.
@@TheNiteNinja19 Any lamp will fit in any socket if you're brave enough ;)
Jokes aside, you can use conventional E26/27 and GES sockets with mercury lamps. I have and continue to do so for my 50, 80, 125 and 250w mercs. What you really need to be cognizant of is that you have adequate control gear to limit the incoming current. BLB mercs will run on standard mercury gear as their internal structure is identical to standard clear and coated lamps, so a basic reactance choke or leak transformer used for the specific wattage you have will do the job perfectly.
Stop. Are you saying a black light MV bulb wctually exists?
Those LED lamps use a dirty little trick. They operate near the edge of the spectrum between visible and UV-A and are technically on the Visible Spectrum at 405nm, but they are close enough to UV-A to provide the effects. There are LEDs that are deeper into the UV spectrum (still UV-A), but they also have a visible side effect in the blue range, thus requiring Wood's glass where the visible imposters at 405nm look more like a BL-B lamp. Oh and any CRT will glow under UV-A and 405nm light. I have a 405nm laser (the same wavelength used by Blu-Ray) and it is pretty cool to play around with.

Thanks man, you saved me some time and money. The florescent bulb seems to be the go to.
The fluorescent black light gives a black light effect it is the go to one
7:52 Let's go ahEaD
Ye
Why didn't you show what your bedsheets look like under UV light, aye?

The incandescant versions are hot enough to melt solder. I had a couple of those back in the late '70s.
Probaply because the black glass absorbs visible light and a lot of it turns into heat.
@@alfepalfe That absolutely has to be the reason why. I had incandescent black lights around when I was a kid back in the '70's, and I learned not to touch them, even after they've only been on for a half a minute.
@@t41flyer due to them running hotter than usual for the same wattage of an ordinary incandescent, the lifespan is severely reduced (around 500 to 700 hours)

fluorescent tubes are the best at being black lights especially if they have no phosphor so it's just emitting the UV light from the mercury vapor
I had that tiny 5" B/W TV back in 1985. I remember getting it for my 12th birthday present from my grandmother. It cost a whole $49.99. And holy cow! I really had low expectations for the LED filament bulb. My same thought as yours is destroyed. I used to think fluorescent lights were the best at producing black light. I have a Sylvania 15" fluorescent tube I got back in 1988 in a yard sale for 10¢ that was made in what I believe was the 50's with the very retro triangular S Sylvania logo. It still works and I still have it to this day.
405 nm lasers (operating just outside the UV spectrum) produce fluorescence with violet visible light. The Philips bulb would be producing violet light of around this wavelength (in addition to UVA), and this may account for its greater effectiveness relative to the Gemini bulb that has most of its violet visible light filtered out by the Woods glass
Thanks for making this video
U saved my Halloween 🎃
The incandescent versions get hot as soon as you turn them on.
You all prolly dont give a damn but does anybody know a way to log back into an Instagram account?
I stupidly lost my password. I would appreciate any tricks you can offer me!
@Rocky Matthias instablaster ;)
@Andrew Emerson i really appreciate your reply. I got to the site on google and Im in the hacking process atm.
I see it takes quite some time so I will reply here later when my account password hopefully is recovered.
@Andrew Emerson It worked and I finally got access to my account again. I am so happy!
Thank you so much, you saved my account!
@Rocky Matthias no problem =)
I have the CFL blacklight version, but it is spiraled.
Works great, use it at Halloween and the kids like it.

I believe the incandecent and florecent ones get so hot because the black glass absorbs a lot of the non uv light and heats it up.
4:00
It's not glowing because the small amount of UV that a tungsten coil will give out when glowing hot is not anywhere near far into the UV spectrum to activate the phosphorescent materials used for the safety strips. That UV is enough to make really easy targets work, markers, clothes, phosphors.. not the stuff on banknotes though.
They also have mercury vapor black lights.
Also the incandescent UV bulbs have their filaments run hotter than ordinary bulbs of the same wattage to result in higher UV output. I'd go for the CFL for the top option and LED the second option for black light usage
Fluorescent is the best - Minimal visible light for the most UV.
LED would be the best if they used a woods glass envelope.
woow that is amazing
black light is really the best and very cool lamp
Incandescent has next to no UV output. Surprised they sold them specifically for this purpuse.
i noticed the fluorescent makes your finger nails glow, but not the LED .
Exactly what I was looking for, great upload
4:48 "and a towel does the job just fine"
Meanwhile, the towel is burning on the side. Lol
WOW!! Love me some black lights! This content definitely helps me with my next videos! Thank you!
Nice demo, though your lighting bar is not so good. Switch between two live open sockets - wonderful for poking your finger in whilst searching for the switch!
For the longest time my dad had a black light in his bedside lamp. It was a perfect night light if I ever had to go sleep in there and it wasn’t very bright.
My best friend as a kid had an alarm clock/nightligjt that was a neon tweety bird and Slvester the cat and had a black light bulb in the unit. It was awesome.
Oh so you've being racist now cause you said it wasn't good enough.
Ordered 2 of the L E D thanks for the video saved me time an money.
The brightest one emits a lot of blue light onto my IPS-LCD smartphone 🤣💀
LED UV flood light with the chip looking diode board in the middle is what I've had the best results with. It was a 30 watt, so it was really good lol 395 nanometer wavelength
Can you link the products please
I was looking for black light, not purple or violet
Most bulbs give black light when turned off. This effect best can be seen in dark room.
Excellent. I loved this and it's very clear and helpful. Subbed.
👍💖
I have 4 black lights 2 fluoresce tube 48 inches and 1 24 inches and 2 led they both do a good job of glowing
Thank you for the video. Sure would have liked to see that pen glow.
i want to use one of these to light up my room. would it hurt my eyes ? i only sit on the dark anyway
Voice crack at 7:51 lol it takes balls to upload a video with your voice crack. I’ll give you props for that.
Some plastics and clothing will fluoresce in blue when exposed to UV
Even some paper will glow!
And anything that contains white wash and fluorescent compounds.
I want to see how the black lamp works
Why did you mention the pen
Have you tried uranium glass?
I had a few cheap no-name filament LED bulbs that were made with Wood's glass. Found them at a bin shop for $1 each, so I figured "why not" and snapped them up. Powering them up at home I noticed right away they gave off a very poor amount of UV compared to the "clear" blacklight filament LEDs that I have that are similar to your Feit Electric bulb.
I ended up breaking the glass of one of them and powering it up (taking safety precautions, of course) and sure enough my suspicions were confirmed: the filaments were actually made of 𝒃𝒍𝒖𝒆 LEDs. The manufacturer cheated! They took regular blue LED filaments and put them inside a Wood's glass bulb. The light coming out was purple but the UV was almost nonexistent. Reminded me of an incandescent blacklight.
I think fluorescent blacklights are still the best if you want a lot of UV with as little visible light as possible.
Even mercury vapor blacklights emit not insignificant amounts of visible purple light, with a crazy amount of UV as well still.
Thanks, that was a really good video !
You are definitely sounding like SHELDON :D
Thank u for the useful info. One question if i may ask. Did u measure the intensity of the florescent bulb? Thanks again
I don't get it what is the point of the coating or whatever in the fluorescent version if the excited mercury produces UV anyways
It's like blocking the sun with your hand to look at the corona during a solar eclipse. LOL
It's not coating, it's a type of glass to cut out visible light.
Any opinions on those cheap 40watt Chinese florescent bulbs on ebay that look similar to your florescent bulb in video
It'll have the same effect as in the video. You won't light up a christmas tree, but it'll do a small desk area.
Wow this is actually beautiful I was curious what a black lightbulb will look like and here it is
Thanks so much for the violence
Kedda kedda it’s not actually black, it’s ultra violet. Very deep blue
How much UVB is produced by the fluorescent lights?
Not much as they're made from ordinary glass which blocks most of the UVB rays.
So black light fluorescent lights will produce a limited amount of UVA and regular fluorescent tubes will convert UV rays to visible light and not produce much else.
two fans in one good size room 3 bulbs each which is the best
CFL if you want a lot of UV and not too much visible light.
LED otherwise.
Don't forget to wear ski goggles, tanning goggles or any other goggles designed to block UVA as you'll get eyestrain otherwise.
Ask me how I know.
I need one of these because im building a pinocchio daring journey bedroom. Like the Disneyland ride. That ride is made up of black lights completely! I need one of these
You sound like Ross from Friends
thanks for the video and I just got an led blacklight flashlight and love it it's so fun
Thanks. 100% helpful.
Is long exposure to these lights safe?
No, it can cause eye damage but as far as I know pretty much no skin damage, not even a tan as the UV output is still limited to a degree.
Can you try this test on vaseline (uranium) glassware?
Absolutely and it will indeed glow a beautiful neon yellow as it should do.
The LEDs were referred to as filaments, but I thought filaments are what makes an incandescent bulb. What is correct?
The incandescent bulb is the one with the true filament. When he talks about the LEDs as having filaments, he's referring to the fact that the the LED chips are setup in thin strands inside the bulb that resemble multiple filaments inside the bulb (unlike the true incandescent, multiple LED "filaments", as they call them, are needed to spread the light out adequately as LEDs emit light unidirectionally). The term "LED filament" has become quite common in lighting but those are not actual filaments as they're just thin strips of LEDs made to look like incandescent filaments
That CFL produces fantastic Light
Can they do UV damage to your skin?
The bulbs in the video are unlikely to do any damage to the skin, however I wouldn't say so of a 400W mercury vapor blacklight bulb or of an array of multiple 18W or 36W fluorescent blacklight tubes either.
These are also incredibly dangerous to the eyes and will cause severe eyestrain in seconds of direct exposure as well as photophobia the next day, however no sand in the eyes or welder's flash as they only emit UVA and not a single ounce of UVC unlike welding arcs and germicidal tubes.
For the bulbs shown in the video, let's start with the incandescents first:
The only damage they will cause to the skin is a burn if you touch them while they are hot.
Just like a halogen bulb for example.
(UPDATE: Looking at them especially at close range can cause mild eyestrain from the UV or IR emissions even if they are low).
Now to the LED bulb, probably unlikely to cause any skin damage whatsoever.
The CFL on the other hand might cause a slight tan at most IF you hold it very close to your skin for an entire day, and by very close I mean something like .4 inches away from your skin if not even closer.
Be aware however that the CFL and LED bulbs shown in the video can and will cause eyestrain and photophobia later on if you look directly at them for too long without eye protection.
The incandescents on the other hand -might- WILL also cause a slight eyestrain if you have sensitive eyes, -however because of their really low UV output power compared to the LED and CFL this might not be an issue to most people.-
Definitely an issue too.
Thank you very helpful
The demonstration would have been more informative if the use of fluorescent paints or glitters were employed.
What's the wattage on that compact fluorescent bulb? I'm trying to "light up" a 22x22 garage and trying to determine how strong of a bulb(s) I need. Those are somewhat hard to find, everyone stocks more of the spiral fluorescents... Are they being phased out? Any reliable sites u know that stock these straight black CFLs? Thanks!!!
Walmart sells 21in fluorescent fixture and black light tubes altogether for $11 dollars each, buying 2 would work well for what you are looking for but I would use 4 one in the center top of each wall
Which is best for kill virus and bacterial?
None of these actually, if you want to kill viruses and bacteria, you need a lamp that produces UV-C rays (Black light being UV-A instead and it doesn't kill anything).
They look like regular fluorescent tubes and also exist in the CFL format except they're always clear instead of white for regular fluorescent tubes or CFLs or black/deep purple for black light bulbs and tubes.
BTW they're also known as "germicidal lamps" but definitely not "black light".
Be careful though as despite the fact they produce a beautiful exotic blue light, UV-C rays are quire harmful to the skin and eyes.
You really want to be outside the room and have the door closed when operating a UV-C lamps as it'll otherwise cause sunburns and a really painful eye condition called "arc eyes" or "welder's flash".
Soooo…. It’s hard to see inside the bulb because of the darkness of the glass…. I’m not often a complete shit on youtube - but that information was a REVELATION! So much info, so few words… o.O.
why didnt you put the links to the lights in the description?
What do you mean ,”bigger venues that need more UV light”?
How do they compare to the LG fluorescent tubes & Nichia flashlight?
And I don’t know what the mercury vapor version is.
i have a 70's gemini in my garage somewhere, heats up like crazy
Can you stil buy (do they still make) incondecent and cfl blacklight bulbs?
They most be very rare compact bulbs you don't get them where Iive amazing and cool video!
I know that i must do what's right
365 nm has no blue...those are the best
Why would you talk about your cool pen that you don't have with you to show?
Thank man ,good
سلام عليكم
Parrot, where did you buy that black light CFL bulb?
Xirexter You can typically buy them at any hardware store that sells lightbulbs.
Xirexter squawk
Who else is researching how to make a black light saber😂
Did you find anything?
Gonzalo Fernández u know the foam in the saber you just have to make it black since there’s tiny holes in it light will pass through but it will still look black h need a white Huber crystal thoe so it looks good
A few days ago an incandescent blacklight burned a hole in my shirt
Where did you get the florescent from
where i can get this led filament type bulb?
Wallmart carrys em
Nothing beats the BIG Japanese , EYE™ 400 Watt mercury ( high pressure ) lamps , with the E40 Edison screw base , however you MUST use the correct ballast choke ( which weighs 3 Kg ! ) ...however the CFL type is BY FAR the best for domestic use ( and possibly the only remaining use for this outdated technology ? ).. ( tried - n - tested ) ................ DAVE™ .............
What’s filament.
So my question is would the tube light or the led light work better to cure uv resin
I would definitely use the tube light if I had UV resin to cure as it needs UV but near-UV will also make fluorescent things glow and the LED light does still produce less UV than the tube light, along with more violet visible light.
So in the end even if it manages to make things glow, it still would be less effective at curing UV resin.
Neither. You need smaller wavelengths for UV curing resin.
I don’t think you would recommend to anybody to get the led black light bulb
Amazing
Thats cool those bulbs are 75w
Mooi Voor in de Radio-Studio.
Where can you buy the lumaseries?
Hi, can I get a link to where you buy the ultraviolet Florence bulb? Please.
Ebay and Amazon both sell them commonly
Starter pack for dying light
The fluorescent bulb gives the true uv effect that you are looking for, the other light bulbs are garbage 🗑 and the one you like is just giving more white light and is not a true black light ..
Indeed
Hey can u tell me what exactly the left one is? I want buy it but cant find
BIG R'S
They get very hot because they're running at a high wattages.
If your going to do a video like this, have a dark room.
Bro. It's very interesting, but kinda funny how you bashed the crap out of that philips bulb, noted it for its imitation and not having woodsglass and being cheaper, and then boom! Said it may be woodglass because it made stuff glow. LOL I just thought that was funny.
Is it bad to look into these
You can look at it, but I wouldn't go within a foot and keeping staring at it.
If I use for germs killer do they work?
No. Not these.
For time that works best
What is wood’s glass?
It's specially treated glass that looks black or dark purple and normally blocks almost all visible light whilst allowing UV and IR rays through.
the point is to make things glow without having visible light interfering.
Insect killer tubes on the other end do emit the same wavelength of UV but since visible light doesn't matter in this case, they're made from ordinary glass and so you can see they blue light they produce when going to the butcher's for example.
