Well, just because I'm me, I have to recommend the MaxaBeam /ubbthreads/images/graemlins/wink.gif It has 3 powerfunctions, spot to flood, is weather resistant, and throws like a cannon. But, it's $1800 /ubbthreads/images/graemlins/grin.gif ...........................But, I just said that because I'm obsessed with that light.
In reality, I would recommend the SureFire L4. I5t's small, tough as darts, and has enough light to light up an entire camp site. And, if you need it to be rechargeable, you can get rechargeable batts for it (Pila 168s). AND, you can make it have 2 output levels by buying the daul stage sawitch for it that McGizmo makes so you get better battery life and less of a blinding light when you don't want it. All in allk it's a great light with a very high satisfaction rating on CPF.
