The auction does say they are Catalina Aquarium brand bulbs. They are decent bulbs and the price is definitely good. You might want to get 2 daylight and 2 10,000k if they will let you. All 10,000k will look very blue.

I would use the GE Aquarays bulbs over the Coralife Colormax bulbs. They are cheaper and just as good.

They probably don't add to the intensity quite as much, but the difference isn't large.
