I think candlepowerforums people seem to really like the 2L. Note it's a batch of really nice compromises, rather than something like a Surefire.
The 2L is lightweight, inexpensive, tough. Very useful beam compromises for a utility light: 3-4 hours runtime, maybe 30ish lumens (??), beam a bit splotchy but very useable, dive-quality water resistance, twist-head switch.
I really like the 2L, since they're inexpensive enough to buy a few and leave them around the house or car, runtime is long enough that you can afford to feed it, brightness is excellent.
