I just thought we should revisit this.
Eneloop AA is rated for 2Ah and 1.2V and 2.4Wh for 2100 recharges ultimately producing upwards of 5040Wh of energy.
Highest capacity 14500 with roughly the same amp rating at roughly the same cost per unit is...
Vapcell H10 which is rated for 1Ah and 3.6V and 3.6Wh for 500 recharges ultimately producing upwards of 1800Wh of enegy.
The original SC5w top brightness maxed out on H1 at 500Lm on Eneloop, the SC5w Mk II at 550Lm, the SC5c Mk II at 475Lm.
The SC52w L2 top brightness maxed out on H1 at 500Lm on 14500, at 220Lm on NiMH.
No one has yet been able to produce, accurately or otherwise, exactly what the top brightness lumen output of a SC53w on H1 is on an unsupported and warranty-voiding 14500, though its H1 top lumen output on Eneloop is 330Lm.
Since 220Lm is 44% of 500Lm, can we extrapolate that 330Lm is at least 44% of its unknown top lumen output on 14500? If so, that figure is 750Lm! For SC53w owners running 14500, does that seem remotely correct?!
Or should we extrapolate that since there is 110Lm of extra lumens between generations of SC52 and SC53 on Eneloop, the SC53w on 14500 has an H1 maximum amount of lumens 110Lm greater than the SC52w's 500Lm, which is 610Lm?
Which sounds more reasonable, that the SC53w on 14500 produces 750Lm or 610Lm on H1? In the former, the SC5w Mk II will produce 73% of the lumens, and in the latter case will produce 90% of the lumens, but either way the SC53w on 14500 should not remotely appear twice as bright as the SC5w Mk II, nor should it appear twice as bright as SC53w on Eneloop, though it certainly should appear brighter.
