Energizer has been producing some decent stuff in addition to their usual junk drawer hardware. I've been carrying their "high tech keychain light". It's a 12/6/beacon lumen keychain light with (2) 2016 batteries and a 2/4/4 hour run time. I'm guessing it's regulated because of the short run time. No idea of the material, but I'd have to guess zinc/copper allow (Zamak 2?)
