Dims horribly when Fujitsu LSD (same as eneloop) reaches 1.2v. 1.2v for NiMH is nowhere near empty and should not be dropping to whats basically a moonlight level.
If you buy this light, stick to lithium. If I'm stick pocket rocket batteries in my pants I'd rather just use something bigger.
EDIT: to clarify, it even dims like this on low. what a load of crap. I got more full power runtime on low from the stock alkaline than a nimh.
