Since seeing the Emoli (as well as AW's great protected cells) in 18650 size, the only light body that you can use these on a practical basis is FiveMega's rare Elephant.
I think having a form factor tube that would hold 3 wide would be easier to hold onto, and if done in modular lengths like Leef's 28650 for larger Emoli/A123, or FiveMega's 60 & 120mm addon Elephant sections....would give a lot of possibilities in voltage setups...with battery combos of 3s1p, 3s2p, to 6s combinations using dummy plugs, etc.
I like the idea of having a universal threading to fit Maglite heads, which inlcudes all of the 3" reflectors also.
