Take control over 4 HID light setups at the same time with the lighting relay controller. The controller can be connected to 4 ballasts of 1000W power each. To run the ballast, it uses 240V and 120V power and a relay amperage of 30 amps.
Also, it can be connected to a 120V timing device and a 120V trigger cable. It is recommended to get in touch with a certified electrician before installing the controller, as you may have to arrange circuits and electrical wiring, which can be best done by a professional.
