Query: Perfect for Saltwater Aquariums

I like the fact that you can get higher lighting output with the mirrored backing on this one plus the right bulbs. Or you can subdue it a bit by adding a blue bulb to a standard white (multi-spectrum) bulb. All in all, I find this to be a very good light for the money and especially for anybody looking for extra illumination for corals or invertebrates in a salt water aquarium.
