Hot or just cool? Ultraviolet LED's!!!

sweet! i think this is kind of expensive but this is the first ive seen or heard of these. As far as the "uv ray" paranoia, the amount of radiation emitted from this wee led will make you listen to pink floyd more and shop for UV reactive items, but your microwave or annual visit to the dentist office is exponentially more harmful.
 
just my curious nature but whats the application for one of these? cover your body with them and try to replicate the sun?
 


<< Great...... just what I always wanted...... lights you can't see......... >>



hahaha... i was thinking the exact same thing 🙂
 
Thanks, I was actually looking for these. If you know where I can get purple or violet leds, let me know. Thanks.

ULTRAVIOLET LED
T1-3/4 (5mm) LEDs. Transparent case. 400nM peak emission, 35nM spectrum1/2 width. 80mcd intensity min. Max forward current 20mA continuous, 5VDC Max reverse Voltage. 3.6VDC Forward voltage drop. Produces light in the near UV (super purple) & upper UV-A range. Causes fluorescence in dyes, inks, threads etc. Used in money, safety papers, leak inspection etc. 1" leads. WT: .001
 
don't we rub goop and goo all over our bodies in the summer just to avoid UV rays?


and Winter Spring & Autumn here in Southern AZ....they should just put it in the water.🙂

LOL agreed man, Im in AZ too and my truck is already toasting in the afternoons when I come out to hop into it 🙁

I sooooooooooooooo dont wanna go thru summer again
 
hmm...a light you can't see....

[sales man voice]I'll sell y'all some broken light bulbs, which I like to call "Ultra-Violet", for 1/2 the price that guy sells it for![/sales man voice]
 
If you are using it around a anodized aluminum computer case be careful. You will either have to give your case a light mineral oil wipedown, or risk your anodization decaying, which it does readily under UV.
 
The rest of their LED selection does seem a bit expensive. Electronic Goldmine has really bright LED's at good prices. Don't think they have UV LED's though.



Isn't this the same light emitted as a black light? If so, that's pretty cool.

Yes.
 
Correct me if I'm wrong but doesn't glow in the dark (non-tritium based) stuff glow really bright when bathed in uv light?
If so you could make like a panel or cube out of glow in the dark stuff and put uv led's behind it...
 
From here:

<< UV LED >>




<< This is one LED that you should NEVER, EVER look at directly with your eyes. This is because the invisible ultraviolet radiation is harmful to them, and can cause corneal fogging that mimics cataracts; and can cause even more severe damage to your eye's lens with only slightly prolonged exposure. >>

Hmm... maybe this is not so hot deal?
 
just so you know:


<< UV-A has wavelengths from 320-400nm (nanometers), UV-B from 280-320nm, and UV-C below 280nm >>


so this is emitting longer wavelength (and hence lower energy) UV rays. the wavelength 254nm is particularly bad because this is the optimal wavelength to product TT dna dimerization. not to say that this is totally safe, but it could be worse.
 
This is a hot deal for all you ATOT lifers considering you probably don't get too much sunlight from day to day...

...now if only they sold I.V.s...
