I've been using the SX25L2 for a year or so, it's pretty hard to fault it. It's been dropped, got wet, thrown around in the car and haven't had a problem. Love the UI and the charging port and it's plenty bright with a good range for this type of work.
So, I know I'm a bit late to this game here. But, as a recommendation from someone whose been for a perfect duty light for a couple of years, your may want to check out the Eagletac GX25L2.
Rechargeable, can use 18650s or CR123s if you're need to hot swap, momentary only electronic switch that also does constant on. I have never mixed it up under stress either. Easily accessed strobe, just wish your didn't have to hold the button down. Long runtime for the output. Solid throw (2 football fields to identifying a person). Good flood as well. Stream light Stinger size and shape.
I've found that 1000 lumens at 20k to 25k lux is just about perfect for a duty light. It's intense enough to reach a good distance and it still floods enough to search close areas.
So, any light with output around there will be a solid choice I think. The Eagletac just seemed the best of all the features to me. Though, sometimes I wish I'd gotten the SX25L2 just for the extra punch and runtime.
