I would stick with the Coralife if you could. They have a way better warranty and actually stock parts for repair. CUrrent USA is a little harder to deal with. I sell them both and have less reported problems with the Coralife. Actually only 2 this year. One i sold to a member and the ballast went out; coralife sent him a new one. The second was the other day a light i had would not light. Coralife is taking care of that as well. I have sold eaisly 250 coralife hoods this year with great feedback.
