Yeah same here, I have to use a mogul to medium adapter and a medium socket extension to properly centre 70w CMH lamps in my R47. The adjustable socket is designed for a ED 23.5 to be the smallest lamp.
I did managed to find a couple of 150w CMH lamps with mogul bases though, I have a electronic 150w CMH ballast so I might use that if I find a ballastless fixture.
Hmm, I've noticed some of mine have a little pellet getter instead of the silvery coating on the glass.
It looks like a little metal flag with a circular pellet that's spot welded to the frame. You can see it in this pic. It's mounted on the frame near the top of the arc tube.

Also, I wonder why this lamp has a getter? I thought only HPS lamps needed them? Or do all ceramic arc tube lamps need a getter?
