If your looking for an Alternative to an expensive aquarium light this thing will blow you away. I have a 120 gallon saltwater tank and I needed two 10 watt led's to serve as actinics the blue color on this light is amazing and if you wanted to just have the white serve as the only light source it is the perfect color of white. A very crisp bright white. It also gives the same ripple effect has metal halides its really beautiful.
