After some time swapping out 3.7v Li Io cells to A123s have very pleasing results. A123's flatter discharge has several advantages.

need some way to measure lumen of 64630 and 56580 since both look equally bright and white, and of course the NTC brings vbulb down on 64630.
May have to get a lumen meter.
