I just got two new Radions and do not need my Sunbrite fixture anymore, I am looking to trade it for a brand new in sump skimmer, the cs1 from sea side aquatics or the price of it, Sea Side Aquatics CS1 Skimmer , This Sunbrite fixture is a year old and in perfect condition and has four led tubes, a 470nm, 14k, 14'k, 20k. the fixture has a build in timer and was a terrific light, I saw great growth using it. I decided to replace it due to the cool factor of the radions. The Sunbrite fixture with the four tubes ran me a year ago $1,300.00, in my opinion, this is a great deal.
