This is a very bright light. It has what I'm looking for;cheap batteries, brightness, tailcap switch, and price. However, it doesn't seem as robust as the Metalgear 1-watt(which I've dropped 30 feet, dunked in sludge, thrown across the room...with only scratches to show for it.) It could also use a momentary-on switch. I'll re-review it after a couple weeks of work and a few callouts on the ambulance. Hope it holds up.
