One light that I have had good luck with is the Niterider MINEWT X2 Dual.
It throws out a nice beam and since it is on two seperate lights, you can adjust one to be close and the farther out. It give you some flexibility.

The only drawback is that the batteries will only last a little under two hours at high intensity (3 and half hours at low intensity).

I have had mine for about 7 months now and I am very happy with it.

I hope this helps.
