Kilo-Lumen bike headlight

Step 7 Control Panel, wiring, etc.

The control panel is made from another piece of that 62.5 mil sheet, and has holes in it for a power LED, a brightness control pot, and a cheapo barrel type DC input connector. This is held onto the heat spreader with standoffs and the whole thing slides into the housing and is held in place on the sides by the 8 4-40 screws.

Wiring of this is simple. If you've gotten to this step you will have the regulator board which comes with hookup instructions. To use an external pot, there are also links to threads on CandlePower Forums about that...

As a word of caution, even to the most experienced builders, CHECK YOUR POLARITY and then double check it. This is how I blew out my first driver board. Don't be a dummy like me!
