Functions: • This product can create rhythmic glitter and shimmering effects like the moon. Its special luminance promotes lunar spawning cycles in corals and reef life. It also illuminates the aquarium so that the natural nocturnal behaviors of tank inhabitants can be observed.

• It comes with automatic light sensor, it goes on at night and off at day time. (Or when your main light go off) So you won't need an extra timer on this.

• You can either hang the moon light on the wall/hood or just stick it on the tank bracing.
