The intuitive Kessil® Spectral Controller X for Kessil® A360XE, A360X, A500X LEDs as well as all the 0-10V Kessil® lights features touch control with a vivid color display and offers effortless light control programming for endless customization options. The K-Link communication method is an upgrade of the easy plug & play 0-10V, allowing to network multiple X lights together (up to 32 fixtures per chain) and set individual groups to run their own programs. K-Link is also a two-way communication, meaning the Spectral ControllerX can detect the number of lights in the network, the status of the lights, etc. One controller, two ports: The controller is equipped with one K-Link port and one 0-10V output port. The K-Link port allows users to connect to an X light, while the 0-10V port is for Kessil®'s 0-10V light fixture. A USB power adapter (not included) is needed when using the Spectral Controller X for 0-10V lights only. Using the Quick Set Mode, it is possible to create unique dawn and dusk effects by altering light intensity and color throughout eight different time points. The Acclimation Mode simplifies the introduction of new lights to a tank or new corals or plants to an existing setup. The acclimation timeline can be customized to suit specific needs. In the Manual Mode, light spectrum, color temperature and light intensity are adjusted to the requirements of the biotope.
