Seems like a good bet? I reckon I could find a way to fix this to the bars. Built one of these from scratch over two years ago- but I keep 8 batteries under the seatpost - and it is a faff to wire up. Any thoughts on these?
Seems an interesting light, but my experience of single 18650 battery torches, is that their a bugger to keep stable on the bars. So something with 4 times as many batteries fitted would be interesting to secure and aim (or keep aimed) in the right direction IMO.
Personnally I'd stick with a battery pack version. [url= http://dx.com/p/nitefire-nfc-32-3-x-cree-xm-l-t6-2400lm-4-mode-white-bicycle-light-black-4-x-18650-205636 ]Random 3x XM-L light[/url]
