Holy fuck thank you

Thx

not at all what i was looking for

Thanks man

Thanks mate.

The fluorescent black light gives a black light effect it is the go to one

Ye

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?

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)

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 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.

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.

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.

Kedda kedda it’s not actually black, it’s ultra violet. Very deep blue

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.

Most bulbs give black light when turned off. This effect best can be seen in dark room.

I know that i must do what's right

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.

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.

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

Absolutely and it will indeed glow a beautiful neon yellow as it should do.

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.

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.

Xirexter You can typically buy them at any hardware store that sells lightbulbs.

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

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".

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

Ebay and Amazon both sell them commonly

BIG R'S

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.

No. Not these.

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.
