I just received the leds from the GB. Immediately, I powered one up with 2 x 2016, the same cells used in those keychain led lights. Few observations...
1) There's not much to see; the light is weak; it doesn't fluoresce things much at all.
2) I've been told that 360nm should fluoresce the US $100 bill well. Uh uh. Can't see Jack sh*t. For a moment, I thought I got a phony bill. Fortunately, I have a small UV fluorescent lamp. Using that I can see the red stripe. Pheww...
3) A donut hole in the beam? I've never seen a 5mm led with a donut hole until I got these.
4) Compared to other UV lights I have, the 360nm led does not fluoresce things nearly as good. In fact, most things that lit up like a Christmas tree using my other UV lights, would not react to this 360nm led at all.
Obviously, these are only my observations. I'm in no way trying say anything negative about GB. chimo did us all a favor, and I'm thankful for that. Now, about these leds, I'm not sure if I want to waste a good X5 and put these leds in it?
If anyone has seen positive results from using these leds, please let me know how.
Thx,
