Just received my satelite freshwater led light. I purchased the 36-48 inch light to supplement my Finnex Ray ll DS for my 46 gallon bow front tank. I will say that I am very dissapointed with the light, although I do like the different settings on it. There is no way I could grow any plants with it if I used it alone. After reading different threads on here I thought it wouldl be a really good addition to my lighting. I will order another Finnex Ray ll DS in the near future when I can save up enough money, and try the satelite on two low tech ten gallon tanks, but I have my doubts on being able to grow plants even in them.
