Lots of folks on this board have been using the XM bulbs for quite a while now and I think most people love them. I myself have not tried them other than I borrowed one for a test a couple of days but it was fine with me for that time. I was comparing one of their 20Ks agains my radiums I was running and couldn't tell the difference with the naked eye.
