I was at Home Depot the other day. They have some reading lamps that have pc bulbs in them. The box said the light gives off natural sunlight. I think it was 28 watts. Will this be good to light my nano tank. I have a 55G saltwater tank with MH. loaded with corals and live rock. I spent alot on the tank. I wanted to do a nano for my office. Just wondering how this light will work
