@xcandrew -- for what it's worth, I get great burn time out of 18650s. I'm about to run through the night (~13 hours of dark), and can imagine that I won't have to switch to my backup battery pack. (Though I'd be a fool not to have a spare battery...)
And regarding other comments about color temp/cri, I initially wanted something a little warmer, but am now perfectly happy with the 4500K. The color rendering might not be the highest spec possible, but it's perfectly adequate. ymmv.
