LED aquarium lighting is most commonly used for nighttime lighting but has recently gained traction as being the main light source. Using an aquarium moon light has many benefits, especially for reef tanks. Moon lights complete the day/night cycle and can be synced with a timer to match the lunar cycle. Doing so can stimulate coral spawning and create great nighttime viewing. In addition to creating a cool shimmering moon light effect, LED lunar lights give you a window into what your nocturnal pets do at night. Using LED lighting as the main light source also has many benefits. LED bulbs are extremely energy efficient and last up to 5 years (50,000 hours). LED lights produce very little heat, are highly customizable and among the most handsome (and small) fixtures on the market today.
