I assume the Alpha has low voltage protection, so no need to use protected cells?
Thanks!
BTW: As a very experienced professional,
in my opinion, I can think of no other word to describe what you're experiencing, as described later in this thread, than the highly technical term: FLAKY. Not a term I like to use, especially when describing a flashlight.
I know nothing about this light or its ancestors, but I'm not sure why you're assuming that it has "low voltage protection". I might have assumed that too, since I gather this is an update to a previous model to (among other things) incorporate support for the common lithium ion chemistry (16340) cells, so one would hope that would include a 'low-voltage
indication'. However, have you looked at the 'run-time' graph on the web site product page? What I see is a 'low voltage indication' feature, which is even notated on the graph, for the blue line - CR123A. What I see on the orange line ('16340') is a vertical drop at the end. If true, this is odd, and the opposite of what I'd have expected. I think they're recommending a 'high-drain IMR' 16340, but most (if not all) of the ones I have don't incorporate a 'low voltage' cutoff circuit, which makes it all the more odd. So far I haven't seen the recommended cell on their site, although I guess they do sell a 16340 for their G-EDC-RCR, but I'm not sure what its characteristics are.
Let me know if I'm missing something here, as I was contemplating possibly ordering one of these, but am slowly talking myself out of it.
Edit: Maybe that vertical drop at the end of the orange line is in fact the 'low-voltage' indication I mention, only the
indication is 'darkness', which is not ever my preferred indication. I prefer something like an 'off-on' blink or the like, such as one apparently gets with the CR123A, but maybe 'darkness' just 'is what it is'.
