I have a G2 with Led, a 6P in my surefire 870 forend with led as well and a L1 lumimax 2 levels of intensities, 10 lumen for reading maps and such and 65 for lighting things up, I know it hurts, except for the G2's, unless you get the Led, but still affordable, but they are tough and the prefocused beam does give a 360 degree, spot free illumination. My day to day is a Streamlight stinger with an LED conversion, and it is great, big though, but rechargeable, with the LED, charge on Sunday, good til next Sunday. I keep the L1 in my other pocket, for backup and low level use, had it now, 29 months, and have replaced the batteries once. I have a lot of flashlights, of the high end kind, Surefire never fails to satisfy, although I have had really good luck with others, Insight technology for 1, and multiple streamlights.
By the way, my current streamlight stinger has a Terra lux LED conversion, a 40 buck upgrade, but it really waked a good flashlight up even more. Went from 65 Lumen to 120 + longer battery life.
