Thank you 2HOW, a very good side by side comparison. I also own the streamlight, stinger xt and the ultra stinger that stay in chargers afixed to the headboard of my bed, always charging and always ready.
A question to USSA-1, and I had not really thought about this until, the surefire led's came out, a friend of mine got a surefire weapon light that fits on the picatinny rail and it is an led, in the home with a really bright light, you get what I call bounceback, or anyone in photography might say reflection, the reflection from the walls illuminates Me as well as others, Me and mine being my 1st concern, The Led version gave a nice white light that did not blind me, but illuminated the area very well, with surefires focused beam, but the 120 lumen + lamps illuminate me and also in some circumstances, take away my vision.
My L1 digital, with a 10 lumen setting is great for reading a map in the car, where anything brighter, not only lights me up for outsiders, but blinds me when reflected off the paper.
Although I own probably a thousand bucks worth of illumination, and think, they are mostly overpriced, I bought them anyway, as the good ones do the job, and what is job worth???
This is a great thread, keep the input coming in.
