your batteries (no indication if they've got IC current
limiting). Maybe OK if you're in a hurry, but I can get 145 lumens with IC current
limiting for $4 each + shipping
(& they don't weigh anything).
Not sure on lumens, had them shining onto teak
side boards, really pretty light, good enough to read in.
As for voltage range I tested for several minutes at 2V intervals up to 20V and they got hot but did not burn out (may have done if I'd left it there). Reducing back to 14V they cooled off again. There was no variation in the output lighting.
I also liked the low profile body with built in swivel.
