I think this is probably a good bet.

Amazon.com : Bright Eyes Rechargeable Bike Headlight - NEW SQUARE MODEL With New 6400mAh Battery - POWERFUL 1200 Lumens - FREE TAILLIGHT AND DIFFUSER LENS Included, Limited Time - WATERPROOF - No Tools required - LIFETIME WARRANTY : Sports & Outdoors

I just bought one of their batteries, they seem well sealed (I haven't had time to do a run-down test with it yet). They include the diffuser lens that I love.

A friend just got one for Christmas. It's OK. There is a hot spot in the middle and the spill is not as bright. He's only used it once. I got to play with it. The next thing is to try the diffuser. I think it's worth the money.
