The slim low-profile hood contains vibrant LED lighting that is capable of sustaining and growing healthy, vibrant corals and live plants. It also includes an integrated 24-hour timer which makes it easy to control the three independent light channels for maximum beauty: bright white, sparkling blue and color enhancing LEDs. The automatic 30-minute sunrise/sunset and 60-minute moonrise/moonset function is incorporated to replicate a natural day/Night cycle for your aquatic environment.
