Im looking for a light a little smaller than my 18650 d25lc2 that I currently use daily. I'd prefer to run rechargeable li-ions than primaries. What recommendations do you have that allow the light to run regulated and still have multiple modes using the li-ions? Would like to keep the price at 60 bucks or under and of course maximize output levels and runtimes
Would look at both the rcr123 and 14500 form factors.
