A little patience and you can do that yourself.
1. Open up the head( not easy, but not imposible to do)
2. Grab yourself a MCR20-S reflector available at the Shop
3. Get a SEOUL emitter, Photonfanatic provides those...Go nowhere else.
4. (optional) Grab a UCL lens from flashlightlens.com (22.8mm)
5. Desolder old emmiter, and install new one
6. Intall reflector
7. Put everithing back togheter.
8. Done!! Change callsign form KL1 to KS1-R!!:thumbsup:
Thats basically how I did mine, opening up the reflector is a complicated task, thats why most people leave this to Pros like Milky... I used strap wrenches and the bottom part came out effortlesly, but the heatsink part I had to torch it a bit to soften up the locktite. The rest was soldering. here are some links to threads involving this mod.
