Newbie here, gosh am I glad to have found out that I am not alone with my "problem", i.e. flashlights! What's her name has been claiming for years that I have a "thing" about flashlights, hinting about abnormal. Presently I only have a handful of Maglite's, some small plastic 2cell AA junk, a Xenon from Cabella's, and a couple of Fenix TK-10's. Just ordered a TK-35 but let's not count that yet. What I NEED is a good UV or blacklight type light for scorpion detection. With summer approaching it's just a matter of weeks before they'll be out at night. And advise would be more than welcome. Not ready to build something just yet.
