Somewhere on this forum I have seen a single cell (CR-something) that will replace the 3 AAA battery pack used in the Serfas HL-2 headlight. Suppose to last longer, maybe more power? The light is 1/2 watt LED. I want something better than just 3 alkaline batteries. Also maybe rechargeable. Suggestions?
