Kessil A360WE Controllable LED Aquarium Light, Tuna Blue

The a360 features Kessil's new proprietary Kessil logic, a unique form of spectral intelligence developed for precise color blending and optimal coral growth. In this new design, instead of varying the light intensity of two different channels to find the desired color and intensity mix, users can select the perfect spectrum and color with one knob and then adjust the intensity with the other. Kessil logic will not only dramatically improve the user experience, it will also boost the light output at both ends of the spectral tuning range by as much as 30%. External controllability in addition to its enhanced manual controllability, the a360 comes with a pair of ports that allows the fixture to be governed by external devices. This new control interface operates within a 0-10vdc 10vdc range, making it compatible with several popular aquarium external controllers. When daisy-chained in series without an external controller, the first a360 acts as the master unit propagating its settings
