Check out the website for more details. I have made a huge order with IceCap after the first sale went so well. I have now included 660's, 430's and a awesome package deal with a pendant, ballast and a hamilton DE 14K 250W bulb as well. They are now in a special section on the website at the top of the list. This sale won't last long and at these prices you will never see again. Here is a quick link to the sale section.
