Wrong band of UV. The band of UV coming from the lights we use in the computers doesn't do damage to your eyes and such.

will uv give you a tan? yea probably.. itll also put little scars in the back of your retinas and cause the lense in your eye to yellow

sooooo.... who still wants to run blacklights????



the yellowing process actually happens no matter what as you age. and the yellowing is a protective process to prevent scaring.

uv also has negative effects on your mood....

If you look hard enough, you'll find where they get it from (some theater prop maker) where they sell it for $28 for a full pint. (but then, why would you need a full pint when only a few drops will do?)

I can't speak for caseetc, but I can assure you that's not where D-Tek get's theirs. I don't believe that caseetc does either. The theater props place sells paint which uses pigmented particles. It's more like glowbottles rather than dye-lite. Dye-lite is a dye, not a pigment.

The blue dye at dtek DOES glow well. The clear/blue is fine. It's the darker blue dye at caseetc that doesn't glow well. Also, there IS blue dyelite brand as well. It's actually the same clear/blue color you can find at D-Tek and caseetc.

Also, I have heard that Tygon tubing DOES block UV light, as does, apparently, the UV stabilized Lexan on some waterblocks. It glows, just not well.

Of all the colors, the green DOES glow the brightest though.

blacklights are uv-a

uv-b and uv-c are alot worse for you, but any type of uv can still cause cancer.

uv-a IS good for you, but NOT alot.
UV-A penetrates deepest into your skin because it is the narrowest of the UV rays.

"UV.A, from 315- 380 nm, which is the closest to blue light in the visible spectrum. They cause the skin to tan and help the skin produce vitamin D. They are also implicated in some types of cancer and other skin disorders. "

my previous statements about retinal scarring and lense yellowing are something that naturally happens as you age, it is NOT good for you, but is just one of those things that happens and the doctors tell you you should try to minimize your exposure to.

hell... us geeks sit inside so much, a little uv-a is probably needed =)
but ive seen several pics of people's desk areas with big blacklights sittin around them. THAT is not good =)


if your super worried about UV-A, simply install the light where you can't actually see the bulb.

flourescent lighting also gives off this radiation, blacklights just try to block the visible spectrum (hold a flourescent light up to your dyelite filled water and it will glow, unless you have a weird tube)

Thanks Avatar28, I corrected my earlier message.


I'll look into this whole UV thing and report here, at a later date. I'll try to include definitions of UV-a/b/c and how they relate to the actual wavelength (in nm, nanometers), and what different sources of blacklight project.

I was really hoping to use UV LEDs, but they're just not powerfull enough. It seems that it would be far, far easier to use a cold cathode blacklight, or one of those handheld thingies wired up to the PSU.

I just wish I knew more about all this!
