LTL Controls Master 4 Four Lighting Relay Controller - Without Timer - 4 x 1000W Ballasts - 30 Amp Relay - 120V/240V (Refurbished)

Switch Four Grow Lights From One Timer Signal - 9 x 11 x 7 in

Wiring each high-intensity light to its own timer adds clutter and failure points. This refurbished relay controller lets one 120V timing device switch up to four ballasts together. It includes a 120V trigger cable, and its relay is rated for 30 amps.

The compact enclosure suits a grower running a four-light indoor room who wants central control of lighting cycles through vegetative growth and flowering. The unit does not include a timer, so you supply your own 120V timing device.
