If you don't need a floodlight and want to go lightweight, I'd recommend Black Diamond Ion as primary. Many people think they're not bright enough to be useful, but the problem isn't the light, it's the batteries. The included battery and Black Diamond replacement batteries are terrible, in my experience. Put a compatible lithium camera battery in it, and it's like night and day. For backup, a Photon, left in demo mode to ensure that it never gets drained by accidental activation.
