Thanks for the input guys!
But I have to ask:
I like the DealExtreme SSC P7 900 lumen and have a friend who dives with it and loves it. I'm not so keen on the rechargeable battery because, well, I have WAY too many proprietary rechargeables.
Batteries for my 2 different cameras, batteries for my camping LED, and now batteries for my diving light. That's 4 different chargers I have to carry around with me and to keep track of. That's 4 different chargers I could potentially misplace. If I misplaced the charger for the SSC P7 the dive would be over.
On the other hand, I will never misplace the charger for my AAs/AAAs.
Unforunately, the AAA lights recommended do not have High, Medium and Low modes. Are there any with these modes?
BTW, wouldn't this be awesome - a magnetic switch dive light that uses AAs/AAAs, has low, medium, high, and strobe modes, has a focusable beam, and is at least 200 lumens?
