I'm running two Vertex Illumilux 48" over my 150 Gal. One is Marino Bianco and the other is Marino Blu. These fixtures are the sleekest I've seen in LED! They have a better shimmer and are evry bit as bright as my Pheonix halides! I suggest you seriously take a look at these before you make a decision. I got mine at Red Coral in Lethbridge. I thought about the DIY approach but I wanted something that didn't look too "Frankenstein" over my tank. Here is a good comparison of True Lumen Pro, Reefbrite, and Illumilux
