Hi, I often find myself on a dark beach with 3 different flashlights.
A 365nm nichia a xp-l hi and a green led keychain for retaining nightvision.
My ideal flashlight has 3 emitters nichia 365nm,xp-l hi & a unknown RGB emitter.
3 emitters that i can switch between that start dimmed down and increase brightness by clicking or holding the button down.
Memory, it should be able to remember last brighness setting for each emitter and in case of the rbg emitter also remember color setting.
All of that in a floody host, Convoy s2+ or something bigger maybe, suggestions?
Im a complete newbie, what do you think is it possible to build?
Hope i posted in the right place, thankful for any input.
I think it will be difficult to have all three in one light because you will want a filter on the UV emitter but not on the others. If you stick with an optimized UV light then you could have a second multicolored light.
Some of your calcite should fluoresce. Get a Convoy UV light and check them out. There are quite a few threads on BLF about UV lights if you want more. There was an old thread here posted by someone I thought was from Finland who was looking for amber on the beach using a UV flashlight. He wanted a light to help avoid stepping on the seals.
You mean red led? Also, you might find a very dim white light is better for night vision, from what I’ve read, most red led lights “for night vision” are too bright- if you can see the colour of the LED, then it’s too bright.
I’ve a dedicated UV S2 with visible light filter, highly recommend this set up if you’re serious about mineral/etc hunting- you’ll find the nuisance blue/white light from unfiltered UV is actually quite bright.
Edit to add: when building your light, don’t forget that optics typically block UV, so you’ll need to go for a reflector.
