KL1 work with a 3x123 mclux body?

[shannow]

I know the bezel will fit but can it withstand 9volts?

yep

KL1 is a buck (step down) and boost (step up) type of light. /ubbthreads/images/graemlins/smile.gif
You will get more runtime but same brightness out of it.
but from the data that i gather so far, it is most efficient to use the KL1 with 1 123 cell (or 2 AA batt)

I have a KL1 on a McLux 3X123 for use as one of my long runtime lights. It works great.

I've had my KL1 running on 3-123 cells with a UBH-II for quite a few months now. No problems running 9V here.

Really? I thought buck was more efficient than boost in general.

Yeah, IIRC, the runtime goes from 1.5 hrs on one cell, to 4 hrs. on two, to 7 hours on three. Running on one cell is the least efficient-it sure fits in your pocket better, though!
