Complicating the answer to that question is that flashlight battery
powered lights gradually become dimmer with use. So as a general
rule-of-thumb I halve the mfgrs' ratings to get an approximation of
/useful/ battery life. It's easy to be fooled -- the lights may appear
bright at first when turned on, and then they'll dim with continued use.

Use rechargeables (NiMH). Not only will you save money over time
and stop creating unnecessary toxic waste, your lights will not dim as
they do with disposables. The discharge curve (volts/time) with
rechargeables is a lot flatter.

I think that's a very good suggestion.

If going the rechargeable route it could also be
tactical to seek out front and rear lights that
use the same sized cells.

Mountain Equipment Co-op will take spent cells
off customers' hands, for ecology respecting
disposal. Perhaps there are other sources that
do the same.


cheers,
