Testing out my GXB172 50W Single-Cell Boost Driver (set at a conservative 4.2A ~6.3V output), driving a Nichia 144 E1000 5700K CRI9050 LED. I'm pretty sure this is the most powerful single-cell boost driver (17mm diameter) anywhere on earth today ^_^.

Please excuse the poor white-balance and the camera's auto-gain adjustment, and the high-pitched sound which seems to be coming from the background air conditioning or something else.

This is a very quick video to demonstrate preliminary and basic firmware capabilities. The GXB172 is a home-made 50W single-cell programmable constant current boost LED driver designed for 6V and 12V LED emitters at very high power levels. Tested up to ~7.25V 6.5A output with ~15.6A input.
