I have had incan Petzl Myo headlamp for 3 years and now it was finally time to upgrade it to SSC P4 u-bin led. Here you can see the Myo before modding:
First I disconnected the wires coming to the light unit and removed the reflector:
Then I removed the plastic incan bulb socket...
...and dissamblied the socket so that I could remove all metal contacts:
How to heatsink the led, the light is made of plastic? Answer below: I built a copper heat tower and aluminium heatsink:
Here you can see the hole I made to the headlamp case and socket for the heat tower:
Below is the led and heat tower installed:
That's what the heatsink looks like. It runs quite warm but it stays touchable even after 15 min run which is good becuse you don't want to keep boiling aluminium on your forehead skin!
Front view with the reflector installed:
Below is the general view a the finished mod. You can also see the switch I installed and the DB500 converter wrapped with blue tape:
Below is a beamshot. The beam is not perfect but it is decent for outdoor activities. The original focusing ability is still there. In this photo the beam is fully focused...
...and here it is fully unfocused:
Runtime is some 7-9 hours.
Thanks for looking!
