based on that infor I guess Im leaning towards lights that can take AA or AAA Sanyo eneloop (NIMH LSD) batteries. Which lights will give me around 150-200 lumens, waterproof (again enough for rain), have run times over 3 hours?

I am curious about the 18650 Lithium-ion lights. Is this a quality setup for around ~50 bucks? that meet my requirements? Will I have to worry about over charging or having the lithium batteries explode?

f you decide to go 18650, make sure you get protected cells for safety. I use these:

What is the advantage of the 18650 over just getting the LSD Nimh eneloop?
