+1 on the SureFire G2 LED
I played around with the G2-LED with lanyard kit this weekend camping. It was awesome. My son was using my G2-Xenon which gave out the first night. The G2-LED was used heavily setting camp in the dark Friday night, plus loaned to someone to look for a lost ring, and other other various nighttime uses. It's still very bright and gives a fairly white light.
The lanyard was useful to hang the light around my neck. I could shorten it some to leave my hands free to do things like tie knots, pound stakes, etc. It was nice not having to search pockets to find the light or worry about losing it in the tall grass.
It's a very bright, rock solid light. One power usage graph on CandlePower Forums shows the G2-LED starting at 80 lumens, dropping to about 65 lumens after 20 minutes, holding at 65 lumens to about 4 hours or so, and then dropping to around 15-20 lumens for the rest of the 12 hours of burn time.
It's pricey at $65 MSRP, but I've seen at least one online vendor selling them for $55.
Cheers,
