Cheap Incandescent Headlamp Conversion
Harbor Freight sells these cheap incandescent headlamps for like $3.00. For what they cost they are not half bad. Still, I’d prefer an LED over the incandescent bulb.
I had one of these Harbor Freight headlamps (HFHL) and a broken1 LED flashlight. The flashlight used a 1 watt LED mounted to an aluminium PCB. The flashlight’s driver still worked too so I used it and the LED to convert the HFHL.
I removed some of the guts (plastic bits) from the HFHL to make room for the new LED, heatsink and driver.
I initially tried it without any sort of heatsink bu, it had “heat management issues.”
After adding the heatsink the temperature stayed reasonable but I drilled some holes in the top of the case so heat could escape.
Works pretty well.
