I have used many different types of flashlights in my work as an industrial electrician. (often work in dark places and sometimes at night) I have to carry a flashlight. Same as the rest on my crew. I and the crew have used everything over the years..Maglite..Streamlight and about every fancy "tactical cop" light made.
Last year, our employer bought the whole crew some Inova rechargeables.

Everybody loves these. They put out like 300 lumens. Plenty bright with different brightness levels (even has a strobe mode) Mine has taken a beating in the last year. Other than the size, the main thing I like about it is recharging. The charger, BTW, works off either 110VAC or 12VDC. I use it a lot and only charge it once a week (usually only takes about an hour)
Replacement batteries are like $20. The nice thing is that in a situation where AC power might be down is that these can charge in the car or any 12VDC source.
