it may seem petty, but my issue is that i need another charger. if i could get a new milwaukee charger that did these also, i would be fine investing in them. but i can't, which i why i never invested in the M4. . . . . .
if i need a second charger, i'll just keep the LED 2 C cell mag lite i have, with the box of amazon batteries . . . . .
Check out the fenix, coast, stream light, nitecore, etc. If you like your maglite LED, you'll not like it after using a fenix, etc. The better fenix, streamlight, etc. are so much better than mag's.
My fenix is a UC35, it has a removable 18650 but also has a mini usb built in, so you can charge it with a regular droid charger like a cell phone I think it's close to 1000 lumens. strobe, etc. The black diamond has a built in batter but charges with a phone charger and also acts as a back up battery to charge a cell phone if needed
I don't have any interest in the mil lights because I already have an array. Even the headlamps (the Mil ones like pretty good), I have a few black diamond ones that are some of the best headlamps out there. I use headlamps a decent amount doing something in an attic, basement or just walking. Light is always where you are looking, both hands are free.
