Here’s a new thing I discovered for yall: Gloworm LEDs (no affiliation) makes really compact, extremely bright headlights for various sports that comes with a remote control module. The remote can switch on/off and cycle through various dim/bright modes on the fly.
This is their XSV light with 3400 lumens (true rating) + interchangable optics. Lights up far as I can see.
The light comes with gopro style base mount or bicycle handlebar mount. I 3d printed a quick release baseplate mounted base with a LM2596HV module down to 8.4v for the light.
Heatsink is for the step down buck chip. Light has been on the board for a bit now and it’s been solid so far. Not as integrated of a solution as a integrated controller but can be moved between boards easily or used for other things.
