So as my primary light system, I purchased 2 Retro kits from Hellolights.com, and I wanted to give a report on them. THey came with the reflector, and the mogul base already t go, and the ballast was already in a box ready to go, I simply had to attach the powe cord from the ballast to the bulb base, and install it in my hood. the bulbs are the XM 175W 20,000K bulbs. ( I love the blue color!) All I can say is wow. I was worried that 350W total light wasn't going to be enough, but I was wrong. The light from these suckers is so bright, it's incredible. For $305 you cannot go wrong. Replacement bulbs are only $65. Hello lights rocks! they packed the items incredibly well, and it arrived fairly quickly.
