Battery options vs. runtime graphs

Which battery/driver option do you prefer?

  • Able to use 2xCR123a, 2xRCR123a, and 1x18650 with curves like the first link.

So I'm perplexed by the decision by Tiablo to make the A9 light engine the way they did. It appeared to me that many people, myself included, were very happy with the length and shape of the A8 discharge curve on an 18650 even given the limitation to non-rechargable 123a cells. The new A9 can take 2xRCR123a, but the 18650 curve is somewhat uninspiring because of the sacrifices required to widen the voltage range. Thinking about it from a user perspective, if you could get the same current to the emitter with 1x18650 and 2xRCR123a, wouldn't you want to use 1x18650? The runtimes would be incomparable...

It's the same thing with the LP MRV, really. The ONLY reason I can see NOT to make it more 1x18650-friendly is if you're planning an expansion body tube, so you can run 2x18650. But for a light like the LP M1 Tactical, wouldn't it make sense to use a setup like on the Tiablo A8 which runs perfectly flat on 18650? It would still have a long runtime on high because the current to the emitter would be less. In the newly released ones they claim 180 lumens, I'm assuming with a Q2 because that's what I've seen Ricky mention, so that's what...~750mA? Quite a bit less than the ~980mA that the A8 emitter sees.

So... I hope the manufacturers are paying attention... what would YOU prefer to see?
