Aye, I got one and plan to use it to replace my night riding MTB light. Fantastic bit of kit. Gonna get a black one tomorrow.
Have you found a supplier of the Battery that fits the case ? 18650 - seems to be the correct one.
So does mine but from Web research they seem to be actually designed for a single battery that fits the container .
Google this - 18650 battery - and you will see what I mine. Although I'm wary as they seem to have funny on/off problems.
good unit but its a generic cree p4 and can be had at dx for £5 delivered
