I just bought the 55 watt kit and installed it last week. It wasn't hard to do, but the finished installation doesn't look all that professional because you have to mount that big ballast somewhere and the wires are everywhere, even though I trimmed them all. Keep in mind that I converted an existing light to make everything fit, so if you use a wood hood, you could probably hide everything well. You can purchase the bulb through them. I picked up the 6700 bulb.
