The new light is a coralife lunar aqualight 72". It has 2 10,000K daylight and for now....1 royal blue actinic and 1 03 actinic. I have to repalce the 03 as it's more purple, but when I bought it (used for $200) they gave me the new royal blue because one of the actinics was out. These, I guess, run about $416 new (search online, I believe it was drsfostersmith.com) so they aren't too expensive new. I wish I had just gotten a new one since I have to replace the daylights also, not knowing how old the ones are that came with it.
