Moonlights boast specialized LEDs that produce the same wavelength as that of the moon. This wavelength creates a more natural nighttime environment for aquarium fish, invertebrates and photosynthetic corals. The moon also heavily influences feeding and spawning behavior. Moonlights create an ideal natural nighttime environment for optimal viewing! These lightweight durable compact strips utilize ultra blue LEDs spaced at intervals of 2 inches to ensure complete coverage resulting in a beautiful shimmering moonlight effect These compacts are designed to be installed in the same manner as regular aquarium lights, above the acrylic or glass cover. The compact size allows for the Signature Series lights to easily sit beside conventional daylight lighting systems.
