I have 2 10,000 K Compacts and 2 blue actinics... It does a good job in my tank and really brightens it up...Seems to be moderate lighting. My Corlas grow like weeds and the blues make the corals glow. I think the name is Coralife Lunar Aqualight. I got them onsale for $200...They are not as powerful as I wanted, but could not pass up that deal considering they are 6 ft. long. And the lunar lights a really cool at night.
