Hi Jakepilot, I ordered them from hellolights.com and I think that premium aquatics had them as well, but they were on back order. You can get 2, 3 or 4 lamp kits. I put the 4 lamps over my 55, they will fit, but it the way the canopy was built it only leaves 3-4 inches for me to get my hands in. I went with 4 so I would have a good start when I upgrade to a bigger tank eventually - after honey recovers from the cost of this one! MLM and JustinL also have these lights and have been very happy with the customer service. good luck!
