Aqua Illuminations Base Controller. Aqua Illuminations SOL Base Controller has two different modes: Auto and Manual Auto mode provides an automated sunrise/sunset simulation with the ability to simulate the lunar cycle. The intensity of both white and blue, day and night may be set. By enabling the lunar cycle, the controller automatically varies the moonlight intensity based on the ~29 day cycle. Manual mode allows you to set the light at a static intensity, for both white and blue LEDs. The controller features a USB port for firmware upgrades. This provides you with easy access to the latest features.
