Here is a fast and easy conversion:
Get the Princeton Tec Matrix headlamp, remove whichever lamp module is in there. Trim the corners on the Luxeon Star with wire cutters (just a little bit), round them out with a file. Use one of the screw mount holes on the LS to slide over the keyway in the headlamp. You can solder wires directly to the terminals at the bottom of the lamp module area.
I put in a magnetic switch, and wired a 15K resistor across it. Has the always on mode, barely glowing for years (well, at least a year hopefully). Slipped a 'rare earth' magnet between the clear plastic head and its rubber cover, the magnet has approx. the shape of a watch battery. It is held very securely in place by friction. When you rotate the head, it has a range of 'on' and 'off' for each rotation. Very solid switch action, the head is so smooth and quiet that you can hear the magnetic switch click on and off.
Nice thing about the whole project is it is reversible, you can recover both the LS and the headlamp if you want. Also you get a professional result, still waterproof and a nice bright beam.
I have not done any runtime tests on it though. Just had fun making it.
