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 timers & contactors protect against this damage by controlling the switching through the contactor instead of directly through a small timer.

Built in the UK, they are available from 2 light to 28 light units.

  • 2 Way = 13 Amp
  • 4,6 & 8 Way = 26 Amp
  • 12, 16, 24 & 28 Way = 100 Amp (these units need to be hard wired by a qualified electrician)

More Information

Green Power lighting control units are designed to control your HID lighting and maintain a safer grow room.

They absorb the electrical power surges which occur every time your HID lights turn on, so that these surges never reach your timer.

'Did you know?'

Huge power surges which occur when HID lighting is switched on can cause the timer elements to fuse together becoming damaged and potentially hazardous. Using a Green Power lighting control unit prevents this damage from occurring.

A safer choice

All Green Power contactors and timers have been designed to help you to maintain a safe grow room. There are no trailing sockets, the plugs are moulded, the units can be hung from a tent or screwed to the wall and the back plate is galvanised and riveted on to the unit.
