charging phosphorescent luminous paint with a flashlight

Now it makes more sense to me. Shorter wavelength = more energy. I have seen a $5 UV light at Fleet Farm and an $8 one. The $5 one had a longer wavelength listed. Based on the higher energy = stronger charge assertion, either one should outperform regular LED lights when it comes to charging phosphorescent pigments. The reason that sun is the most effective of all methods is that there probably isn't a flashlight out there that produces strictly UV-C waves, at least not yet?. :D

Hmmm. Now I wonder about the effectiveness of K-Mart's once legendary Blue Light Special.

PS btw, there may be a UV-C laser out there? bu ha ha ha *evil laugh*

just be careful with the UV lights, just because you can't see it doesn't mean its not frying your eyes. I worked with some guys that did UV puppet theater, they would have to learn the routines through rote muscle memory, as they needed to wear a full hood to protect their eyes. Partly due to an exposure time factor, and using high output lights. Add that to the fact that "dim" lights don't trigger your irises so you are getting a fuller hit than you would outside.

Thank you for the warning. (although I think you meant pupils—not irises...right?) I knew that looking at them directly was bad. I had not thought about how the pupils not closing down made things worse. On the plus side of the pupils not closing... If you shine your bright white flashlight onto a watch face to charge it, you will also ruin your night vision (which also makes it difficult to see your freshly charged watch lume.)

I have a watch with a black pvd case, and another in shiny stainless steel. I noticed that when I charged the shiny watch, that I was reflecting the UV into my eyes. From not on, I'm only going to use it on the PVD watch. I may try not looking even with the black watch.
 
I just tried it... It's very easy to cup either watch in my palm and hit it with the light without looking.

(Yes. That's right— I've quoted myself.)

I just had to look. The house was not nearly as bad as I'd feared. We won't have to move! That's the good part. The bad is that my wife thinks I should sit down to pee. :)
 
I flash my 500 lumen light on my watch and it glows almost as well as if the sun charged it.

I dip the ends of all my knife lanyards in GITD paint, no reason though, just had a lot of paint left over. I think it was v10 paint which was rated very high. I paid about 15 an ounce.
