Update on my Streamlight...
I've liked this light so much, that I just bought a second one off ebay for inside my house. Going to use the 2nd charger mount I already have (AC) and mount it near the back patio door for easy access.
I've bought quite a few powerful lights over the years from places like DealExtreme, but this one has been my favourite so far....probably a combination of the build quality and the fact its never dead or needs charging cause it just sits in the charger and trickle charges all the time.
It's been beat on, dropped, hung out in my engine bay for a week (oops), rolled through oil, nearly lost out wheeling, and been on more jeep rescue missions than I can count. Never had any issue. it always turns on. And if I use it for a long time and drain the battery before I can charge it, it has the smarts to lower the intensity dramatically rather than just flick off. At super low power mode it'll last all night. Reliability is something you want with a flashlight.
