The AcroOptics A243C LED Reef Light provides the power and spectrum needed for any marine invertebrate, from low-light large polyp stony corals to the most demanding shallow-water Acropora corals and Tridacna Clams.

Our Very Large Array design with custom Total Internal Reflective lenses creates a uniform and blended light field across your aquarium, eliminating the common problems of hotspots and dead zones, while keeping the light where it is needed, eliminating glare for viewers. Sleek design and a low profile create an attractive appearance for any reef tank, whether mounted on the tank rim using the laser-cut legs or hung with the stainless aircraft cable hanging kit.

Used by both professional and amateur reef keepers, this fixture is built to withstand the most demanding environments. All-aluminum housing and stainless steel hardware will last for years. High-quality LEDs and active temperature-sensitive cooling ensure years of consistent light output and characteristics, maintaining the stable environment your livestock craves. Low noise magnetic bearing fans ensure near-silent operation.

The AcroOptics Reef Light is the most flexible and robust fixture on the market. Five independently controlled color channels allow you to create the appearance you desire while providing ample light to your tank denizens. You can customize your light profile to fit the evolving needs of your reef ecosystems through the mobile app (available for both iOS and Android) or the on-board touch screen. Recreate the daily solar and lunar cycles of any geographic location, or create your own program, ranging in complexity from a simple on/off to multiple-day ramping for acclimatizing new livestock.
