R2 Solutions R20500 R2 Extreme LED Moonlight covers approximately 3 feet of tank but only measures 4 3/8 inches in length!!! It is extremely versatile and cost effective! The Moonlight tube is designed to produce a 120 by 60 degree illumination by utilizing extremely bright ultra blue LEDS. Installation is a breeze.... simply use the included brackets and double sided tape to mount the unit then angle the moonlight as you desire.
The Extreme Moonlight is also available in a dual set for Larger tanks.
All aquariums have a daylight system. These must be turned off at night for your fish to experience normal day/night cycles. The problem is you can't see your fish! The R2 Moonlight replicates moonlight in a tank and creates a great ambiance at night in your aquarium for viewing your fish (a beautiful, blue, shimmering, moonlight ambiance in the room) and is healthy for your fish as it mimics the light of the moon which influences feeding and spawning behavior.
