That thread which I made a post on is very interesting. AT least to me…
Maybe you guys could speculate on it too. It could be useful.
Interesting concept I think. So how then do you account for the variation in cell capacity? That will completely vary from cell brand to brand. Even the same exact brand of cell will have differing capacities from unit to unit, batch to batch.
For me, Lumens per watt efficiency is a more useful way to evaluate each light. (Lumens OTF divided by tailcap power consumed). The variables still remain: OTF Lumens will drop with temperature, and voltage sag. Wattage consumed will drop (with Vin drop), unless its a theoretically perfect boost regulated circuit.
While interesting it makes it so manufactures could have a high lh rating by driving a XM-L with low currents. I think a runtime graph is much more useful.
