Wich battery will have the best output and runtime? A 2700 mAh NiMH battery or a Lithium battery such as Energizer E2?

I'm looking at a particular light wich gives its data using the NiMH but i will be using Lithiums, so I want to know what to expect.

Make sure the light can use Lithium. It may not if it only mentions NiMH

The ZL AA headlamp will run fine on nimh or lithium. Lithium should last about 2x as long, and work better in very cold weather. The lithium cell also weighs about half as much if a 15 gram difference matters. I usually use nimh (Eneloop) in mine because of rechargeability but would bring a few lithium cells if I were going someplace very cold or if I couldn't recharge conveniently. NiMH still runs the light for a good long time in normal circumstances.
