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 bar can take up to 13 Amps for maximum efficiency we recommend running no more than:

• 3 x 600 W 

• 4 x 400 W 

• 4 x 315 W 

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 bar
