lumii Black 8 way Relay Contactor 

The LUMii BLACK contactor timer is a simple and cost-effective solution for grow light scheduling, ensuring that plants get the optimum levels of lighting throughout the day. The mechanical timer is easy to programme in 15-minute increments, while the relay switch safely turns on HID lights without causing a power surge or overloading the timer.

The lightweight, flexible power bars take up to 13 Amps each for maximum efficiency 

To set up, simply push the timer pins down to indicate “ON” periods, centrally position the ON/OFF switch onto “timer” mode, plug in ballasts to the 4-socket power bars and plug both contactor timer plugs into 2 x 13 Amp mains supplies sockets.
