So, I bought another light, this time from Kaidomain, a direct competitor to dealextreme, and it's a thrower. This
2-Mode HAIII Long Throw R2 Flashight has a large, smooth reflector, and throws noticeably further and tighter than, say my Solarforce L2, as a result.
It's significantly larger than the L2, however, in every dimension.
(images stolen from kaidomain) It's a cheapie, of course, at US$33, so you can't expect wonders, but it seems pretty decent - double o-rings, and scratch-resistant HAIII anodizing (unusual for a cheapie).
Runs on one 18650 battery, and has two modes. The low mode is still quite bright, really. I presume the light is unregulated, at its price point, so I expect it to dim as the battery voltage drops. I used it on and off the other night, and didn't notice any great change.
So, well, it's not quite in the league of the huge-headed JetBeam Raptor I, but it throws better than the other LEDs I've had. So far, it's good for the money, and it feels more tough and manly than most of the lights I have. Time will tell how many times I can drop it off things before it breaks
