There is also some good information available on 250w SE bulbs that Sanjay Joshi wrote a few years ago with good bulb/ballast/par information. Unfortunately there isn't any accompanying photos but there are graphs.
I think lighting will always be a controversial subject. Since I use conventional magnetic ballasts, I'm probably going to move to XM 10Ks replacing bulbs 2 at a time starting in a month or so. I'll replace pairs at 6 month intervals moving the new bulbs to the center.
