If you don't mind the size of a 2x 18650 lithium ion light, I'd get the Fenix TK35UE, 2000 lumen model. Just lots of lumens with a bit of throw too. You will have to take the batteries out to charge separately though. This is the light of all the ones I have that I'd use when at Lake Powell at night going through the cutoff in shallow water looking for obstacles.
