About Lighting Contactors / Relay Units

Ordinary timers can’t cope with the electrical charge required to switch HID lamps on. Ordinary timers are at risk of fusing making the timer fail – so your lights will remain on or off, damaging your plants.

Green Power Contactor protect against this damage by controlling the switching through the contactor instead of directly through a small timer. Details can be found here.

Maxiswitch Relay is similar but for used when less power is required from the switch.
