This light is the "A" version, which does not come with the GoPro mount. When I ordered, I hoped it would come with that tab, but it did not. Apparently, there is a "B" version that comes with the GoPro mount. Pros: The light is small and light weight. It is not glued together so it can be modded. The driver is a strange shape and appears to be glued in place. Threads are good and water seals appear good (have not tested). Cons: Thermal path in this light is poor. There are 2 MCPCBs glued together to make the LED sit at the right height relative to the reflector and enclosure. Also, there is not a thermal shelf, only a small ridge to conduct heat from the MCPCB to the body of the light.

quality of the light itself seems to be good but the mounting holes for the holder are slightly off. Barrel connector is not the common (5.5mm x 2.5mm) it´s a smaller one. Voltage is 4.2V
