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.
I’ve taken this light for walks through the paths in the ravine and the cyan is actually a quite pleasant tint for green spaces. It also clearly illuminates for a an easy visual.
