UV: illuminating scorpions in the desert, security strips in currency, checking hotel rooms for unknown stains, etc.
IR: experimenting with night/low light mode on camera, night vision devices
Red, green: preserve night vision while out at night, (hunting feral hogs at night is legal here)
Blue: Because it was available
FYI, my grandkids have learned that if we shine the red, green, and blue onto the white ceiling in the house the colors blend in interesting ways. Overlapping the three beams yields white light in the center and all the shades of the rainbow around the edges. Science lesson.
DQG Hobi Plus 365nm UV - kept on personal keychain for checkin stuff.
Thrunite ti 365nm UV - kept for charging glow stuff.
Olight S10 400nm UV - used for uv glues.
DQG Fairy XP-E red - hardly used but attached to a cold steel micro recon kept in kitchen for opening food packs.
Nitecore TIP with red tail LED - on fridge.
Nitecore tube with red XR-C - keep it stuck to the fridge, used for smoking by the kitchen window at night.
I have an old keychain light. This was a small plastic light that ran on a few hearing-aid batteries. It has a titanium sleeve around the body. Emitter is a red 10mm LED. Had this one since before white LEDs came out.
I’ve got an oddball C8 sized host that I was able to wedge a ~40mm optic in at the proper depth to make a fixed-focus green xp-e2 thrower for spotlighting game at night.
Also have a couple of UV lights, one with a 365nm emitter and uv-pass filter. The second is a funky reflector-triple with some cheap 390nm emitters.
Also have a couple of old color XR-E P60 dropins that haven’t been used in a long time.
I want to get a 3535 cyan emitter and build a light just for kicks, and maybe try for blood tracking.
I have the UV Convoy S2+ for finding scorpions and anything else UV related, plus an old Maglite 3 AA with the red Maglite lens in it because the local nature preserve occasionally does night walks and they require a red light flashlight.
