Simon,
Is there any plan to use the XHP70.2 in the Convoy L21A (which as you know is another light that uses one 21700 cell)? The L21A has a larger head so I assume a larger reflector, but it appears to only be available with the SST40 or XHP35 HI.
Also, can your standard 4-mode (0.1–3–30–100) driver be mated with the XHP70.2 — in either the M21C or L21A? If so, could we still expect about a 4000 lumen output at 100% (like the current driver in this review)?
Why would the XHP70.2 emitter be any less desirable in the L21A than the M21C (that does have it)? I am under the impression that the XHP70.2 has the potential for about twice the lumen output than the SST40. All that said, I could be completely misguided here.
I believe the L21A is powered by just one 21700 cell and can even run on one 18650. The L6 — which costs almost twice as much (as a L21A) — requires two 26650 cells. IMO those differences are quite substantial.
Today I disassembled the M21C and got some measurements of the reflector + glass that a fellow member requested via PM.
Keep in mind that I don't have a set of calipers, so I used a regular ruler to get the dimensions (so there's a margin for error).
Reflector's base diameter: 26mm
Reflector's top diameter: 45mm
Reflector's height: 39mm
Glass thickness: 2mm
Glass diameter: 50mm
And here's some photos of the glass and reflector:
Simon, please start making modes with 1/2-second mode memory. I am so sick of having to wait 3 seconds for mode memory to set. Even 1 second is too long. Also, consider making a control ring mode selector. That would fix this problem.
