I used to see ultra small pocket flashlights using black LEDs in mail order magazines all the time. I was wondering if there is a place that sells black LEDs separately. It's the best colr I've yet seen, yes, even cooler than blue.

they're probably UV LEDs, don't stare at them too long!

long wave UV is safe but short wave will blind ya,kinda like staring into the sun without the white out

btw-shortwave is the wavelength that causes sunburn

Seems to me like something you don't want to mess with period.

If your desperate to get one, try scavenging a keychain fake money checker, ive seen them in the dollar store for about a buck or so....

What was the colour of the light, since you saw it...?

I think it was a purplish blue. My friend had one on a keychain.

So you risk messing up your vision and living the remainder of your life with vision imparement or even blindness? The same arguement you made could be made for listening to music too loud. Yet everyone here says "don't listen at 100db!!!!" You could go deaf, then what? Life is short, but don't be stupid.

Would not surprise me!

Anyone who is partial to leds ought to check out Lumileds,
Luxeon Star range, they are awesome semiconductors.
