Cool, I'm glad to hear the the bulb lightens up just a bit. you might want to look at JBNY's website, www.cnidarianreef.com
He has all the data from a serious 250 watt SE bulb/ballast comparison test he did posted up there in addition to pictures of the different lights above his reef so its easy to see what your looking at. I'm pretty sure the XM 20K does not have as good a PAR rating as the hamilton 14K, but it might be different on your set up depending on what ballast you are running.
I have read that bulbs will last alot longer than 12 months.....do you really need to replace the bulb at 8 months?
