A project log for Darkstar Mk.II

High power custom caving headlamp you can rely on. Small, not that heavy, water and bomb proof.

After the body was assembled, I could finally test the heat dissipation. On full power body goes to 60 degrees Celsius in few minutes. But full power is ridiculously high, nice for huge domes or for photography, but it makes no sense to use it very often.

The aluminium star heatsinks are not perfect, I guess I'll replace them with LEDs mounted directly on piece of cooper to reduce the temperature of LED itself.

(ignore the date on the image, the thermal camera battery died and the time was restarted)
