Which battery to use?

**DONOTDELETE** · Sep 17, 2002

I have a ARC LS that is my EDC. I currently use it with the 2 AA pack with alkaline batteries. Cost aside, if I wanted the most light for the longest time, which batteries should I use?
The 2AA seems pretty bright, but what would you guys say about the 123? Comparable run times/brightness? Any input appreciated. Thanks!

There has been much testing on bright/longest for the Arc-LS. The #1 for bright is the 2AA Lithium. Not to bad on long also.

Please take a look at this graph:

...run with the prototype, but pretty valid for recent production lights as far as I can tell (still don`t have a "first" LS to test, though I was promised one ages ago), to help you make your choices.

Ignore the 2AA Duracell alkaline results, I think I had a couple duff cells that gave distorted results, but didn`t/don`t have the time or money to run more of them with new sets. Batteries are expensive here.

The rest of it is accurate.

As sunspot mentioned 2AA Lithiums are 'the best'.
Look here run times , from a previous topic.

Why not take (or better make ) rechargeable 123's? Look here for more information.
