One of the most sophisticated and user-friendly Marine LED lights available on the market, the Aquasun 36x3w LED aquarium lighting unit is both high quality and completely adjustable to the requirements of your tank. The AquaSun LED unit supports the option for separate blue and white LED control via a built-in timer. The controller feature also provides the option to set lighting on a 24-hour cycle with 0%-100% intensity, sustaining daylight and night-time cycles set to your own specifications. The built-in controller will also allow you to use both pre-set lighting combinations or customise your own, depending on the needs of your aquarium livestock and invertebrate life. A useful auto-lock function ensures that the controller is automatically locked if left idle for 20 seconds. Each unit has a built in high-performance fan which activates when the output intensity percentage reaches 50%. This creates the increased possibility of cooling during a daylight cycle, when your house is empty, potentially eliminating disruptive evening noise! Sure to be one of the most efficient, attractive and functional lighting systems on the market to date, each unit comes supplied with a remote control, adjustable brackets and hanging kit.
