I've had no luck with rechargeables.
I finally dropped some extra $$ on a good one a few years back.
LightForce is the company. The model is the Marine Light 240 Blitz.
Corded, lightweight, tough, impact resistant, super bright. Was about $125 when I bought it if memory serves.

I agree that it's usually better to run without a bright light at night. But of course there are times when you need one.
