Anyone do anything cool with a UV LED -- Lightsaber build?

Just curious.

Burn out retinas from the wave length. They are UV...most used for curing photopolymers in polyjet 3D printers. If you want to learn more about the dangers high-bandwidth blue light can do to your eyes there are plenty of medical journal articles about it. Check the wavelength of the LEDs before you purchase, and cross reference with the wavelength of a fluorescent black light as I assume that is what you are getting at. I have a royal blue saber that does have a slight blacklight effect to it.

I think I had in mind something similar to a black light.

Sabers have been built with the "safer" UV LEDs. The results are less than impressive. Very dim, poor diffusion. It does not turn your room into a rave club.

If you want to light up something fluorescent, try the blue (or royal blue) with the Photon blades.

my son had a hey dad moment "what if you built a halo sword?!"

The first idea I had was something UV "safe" that would light up some metallic edge painted with a color that would flouresce.. I thought it was highly likely that someone might have tried it.

I would not use metal, too heavy and dangerous. Nth light flexograph printed led sandwiched between frosted or phosphorescent coated polycarbonate cut to shape would be better and obviously has been done. I have an nth light development kit in my office. Amazing little things, but power hungry as could be. There are also electroluminescent inks that have been used on some limited addition Budwieser and Bud Lite packaging and bottles that I have designed in the last couple of years. The ink tech is improving and price is coming down, not bright but will give a glow.

Dang! That's cool. exactly, but looks better the way you have done it!

Thanks for all the input!
