To be honest I'm not a true flashaholic,so not real up on conversions ect. Can follow a schematic with decent instructions on automotive type wiring so might be able to figure it out??? Realy all I want is a good fairly powerfull true UV flashlight that uses standard batteries. Would prefer smaller size too for portability and weight. LED seems the way to go as far as instant on and run time. I paint windows and have just recently started incorporating uv responsive elements in some applications. Need to be able to spot check areas being worked on without moving lights or objects back and forth in the process. Would also be handy for assessing pigments and materials. Have a small collection of M*G lights and just love the 2AA and had the same problem with rechargeable batteries, these stuck in the casing too, almost didn't come out. Any way, this is what I'm trying to find, or something along those lines.
