Pay attention to the dimensions By Nikki on 6/7/2015Nikki would recommend this product to a friendIt's nice to have light coming from the side, no more salt build up on the light canopy. My tank 180 G, the refugium needs two lights. With that said the macro I focused the light on had shown improvement within in a few days.
Works well on a traditional sump By Old Salt on 2/17/2014Old Salt would recommend this product to a friendI had the Innovative Marine suction cup refugium light. It worked well, but every once in a while the suction cup would let go and the light would fall into the water. So I got this one and it works well. It's a little strange having it on the side of the sump (hence the 4 stars) instead of extending over it. But it is bright and grows the macro algae well. Most important it is really secure.
