After a slim AA to tape under the barrel of a 410 shotgun for humane dispatch of animals at night. The fenix e12 at 130 lumens and 1900cd and good battery life would be perfect but comes on at low. Anyone who knows of any simple lights or 2013-2014 era lights( when lights were still sane enough to be used for duty/work purposes. aka turn on and off) that's comes on at high and isn't trying to get 300 lumens from a AA, please let me know. Sorry for the rant lol, but its so frustrating having to pore through 500 web pages of the latest disco marketing to find worklights these days.
