BLUE MOONBased on the popular �actinic 03� spectrum but broadened slightly tofluoresce more corals & mimic the light spectrum on a broader areaof the deep reef. Blue Moon has a pleasing moon light style effect & so can be usedfor �after dark� lighting of aquariums. This facilitates viewing ofnocturnal inhabitants (e.g. catfish & marine inverts); & stops theaquarium becoming an unsightly �black hole� in the corner of thelounge after lights out. If Blue Moon is timed to come on first & gooff last it also reduces fish being startled by sudden light changeson start up. BLUE MOON � Ideal day/night spectrum & light output for: l Supplementing the blue �actinic� part of the spectrum in marineinvertebrate & fish aquariums l After dark lighting for Marine & Freshwater aquariums to viewnocturnal species & create a pleasing aesthetic effect
