For some of the more serious and professional growers out there, even our largest longest-serving lighting contactors aren’t quite big enough for the scale of set up in mind. Cue the introduction of Exolux Timerboards! These well-built units are a combination of timer and contactor that will safely operate many a number of lights if required, with one designed to turn on up to 16 lights and the other an astonishing 28 lights! Exolux Timerboards send power to your ballasts bank-by-bank (4 lights per bank) – so you avoid big surges – and include trip fuses, power failure time delays and a battery reserve for extra protection. Lights also switch on/off individually meaning you don’t need all of them going at once. Hard wiring to the mains circuit is necessary though, use a qualified electrician.
