Had an interesting discovery recently, when I found that a rechargeable NiMH N-cell (presumably 1.2v) would not power an older-style 3-LED UV Baltic, which runs just fine on a 1.5v alkaline.
This surprised me, since the lower voltage NiMH cell works just fine with all of my other Baltic/Shasta/ShastaX Peaks (including both power LED and 5mm LED versions in white).
Is there something different in the circuit for the ultraviolet version? Perhaps the boost driver requires higher input voltage, though the difference between the 1.2v and 1.5v seems relatively small. The output is not simply reduced, it completely will not light on the other cell, BTW.
Just wondering if this is a quirk, expected behavior, or some problem with the circuit ???
