I currently have a swing arm 150W MH over my 37g mixed reef. Could I replace it with 4 30" Coralife T5 aquarium lights. Each light is 40watts and has 2 10000k bulbs. I really want to be able to put some actinic over this tank and the MH just doesnt light both sides because its a swing arm. I just wanted to know if this would be an upgrade or downgrade and if I could keep sps, clams etc with these lights
