Here's my latest mod. It's just a simple emitter swap but it had fantastic results. I was hesitant to rip the Ra apart because it had such a perfect beam, but I am happy to say that with XM-L the beam is just as nice as it was before.
There was nothing too tricky—a heat gun loosened the threadlocker on the reflector, and I used a dremel to remove the GDP locating studs and to shape the XML star to fit. I used a thin copper star which put the XML at almost exactly the right height, although I did need to put some thin high-temp electrical tape on the underside of the reflector to prevent damage to the XML.
I measured my results in a 2 meter integrating sphere. Unfortunately I didn't have the foresight to verify the Ra's stock 140 lumen output. Putting XML in brings that 140 up to 260 lumens on boost! Boost steps down to a high level of 174 lumens. I was so shocked at this incredible output increase that I took the measurement three times, but I do believe it's accurate. I even did absorption corrections beforehand.
If I find time I will put some beamshots up.
