A light controller is an essential component of your grow-room as it will happily handle the electrical load demanded by HID lights. The Maxiswitch 4-way controller is ideal for those using a larger number of lights in their growroom.
The unit works by diverting the live load around the segmental timer to a contactor/relay, the timer simply switches the contactor/relay to complete/break the circuit. This 4-way unit is rated to 13A, it will switch up to 4 X 600W grow lights (600W grow lights draw 3A each in use).
The controller has two UK plugs running from it; one plugs straight into the wall-socket, one plugs in through the segmental timer which dictates the light cycle – it comes as standard with a segmental Timer.
