I realized that I edited my post very late, and should have put this additional info in a separate post. Sorry.
EDIT:
BTW: In terms of other hi-quality multi-fuel options: If one wanted to trade 14500 requirement for 16340, there's another great choice which can use 16340, CR123A, or AA (although it will only internally charge the provided custom 16340). No rotary though - it's targeted to meet the professional tactical backup segment requirements (much as the Streamlight we're discussing). It's the ASP Sentinel e3. Another ASP light lives in my pocket full-time, and I can vouch for their quality - so far.
