Re: Nuwa? QIII 3 watt lights
there is the "normal" one (1 battery) and the "big" one (2 batteries), the latter with a two-stage button (low-high-off) (or is that 3 stage ?? <img src="/images/graemlins/grin.gif" alt="" />).
Got them from Amondotech (indirectly .... shhhh don't say it ...)

The smaller one is just the right size for a (or is it "an" ?) M-1 style pouch.
