I just bought a moon light for my sw tank. It is awesome; however, it did cost me $150!!! It comes with (right from the box) One True Actinic 03 Blue Compact fluorescent lamp; One 10,000K Daylight compact fluorescent lamp; and Two Lunar Blue-Moon-Glow LED lamps. And all 3 have different switches. It also has its own cooling fans. I am so excited!!!! The moon lights are really neat! It is made by Coralife and is called Lunar Aqualight. Its Awesome!!
