The LUMii XLED Controller is designed to control the LUMii XLEDv6 680w LED fixture but can control any LED fixture which accepts 0-10V control signal. When connected to an RJ12 port, (or by wired connection to push-in terminals) it will schedule a desired daily photoperiod, control the light intensity (dimming) from 0% to 100%, and set the length of sunrise and sunset ramping. With its single channel, it will control a linked array of up to 25 LUMii XLEDv6 680w LED fixtures. The controller uses a very simple five-button control interface with LED display. It has an integral wall mounting / hanging tab and is powered from mains electricity via an adaptor plug (supplied).
