i use 90w bulb in my mag with aw switch, and 2,5in throwmaster head, i always used 4x26650 cells, but after reading this i added 88mm extension, and 1 more 26650 cell, a lot better now with 5 cells, too bad the light and the head is gray, but extension is black, may be in a future i'll find gray D extension. with ext. and throwmaster head, 4d mag now is almost as long as 6d mag.
...time to pull my M*g 458 (my brightest and #1 torch - and probably will stay that way) out of the closet after a couple of years - got into collecting rocks and crystals for that time (#1 hobby) but now i'm done and have started reminiscing my 'flashlights'. have the same one as pictured but purple color with standard mag head. same batteries and holder, etc. (thanks FiveMega!!) I like using the Osram 64440 IRC bulb instead since it's still pretty bright but draws a lot less power - less amps through the standard Mag switch. (plus cool looking bubble shaped bulb) - alright i'm back and my neighbors better be ware
