Green Power Contactors

Green Power Contactors have now been discontinued and are no longer available to order. If you were searching for a Green Power Contactor for grow room lighting control, we now recommend the Timer Box Pro 4, 6 and 8 Way W/ Heater Socket as the current replacement range.

Green Power Contactors were used by growers who needed a safer and more organised way to control multiple grow lights from one central point. They were a popular choice for timed lighting setups because they helped take the strain away from standard plug-in timers, especially when running more than one light.

Although Green Power Contactors are no longer available, the Timer Box Pro range gives customers a practical alternative with modern multi-way options. Available in 4-way, 6-way and 8-way versions, it allows you to choose the right capacity for your grow room instead of trying to source discontinued stock.

Recommended replacement: Timer Box Pro 4, 6 and 8 Way W/ Heater Socket

The Timer Box Pro 4, 6 and 8 Way W/ Heater Socket is our recommended alternative to Green Power Contactors. It is designed for growers who need reliable timer-based control for multiple lights, with a built-in timer, durable metal construction and a heater socket version for setups that require a dedicated heater connection.

Rather than relying on a small plug-in timer to handle the load of several grow lights, a proper timer box and contactor setup allows the timer to control the contactor box itself. This makes it a more suitable option for grow room lighting control, particularly where several ballasts or fixtures need to switch on and off together.

Choose the right Timer Box Pro model

• Timer Box Pro 4 Way W/ Heater Socket: best for smaller grow room setups or customers replacing a compact Green Power Contactor.
• Timer Box Pro 6 Way W/ Heater Socket: a good middle-ground option for medium setups that need more outlet capacity.
• Timer Box Pro 8 Way W/ Heater Socket: suited to larger grow rooms or customers who need the highest capacity in this range.

Why switch from Green Power Contactors to Timer Box Pro?

• Current replacement product: Green Power Contactors are discontinued, while the Timer Box Pro range is available as the recommended alternative.
• Multiple outlet options: choose from 4-way, 6-way or 8-way depending on your room size and lighting setup.
• Built-in timer control: helps keep grow light schedules consistent without using separate plug-in timers for each light.
• Cleaner grow room setup: reduces messy plug boards, scattered timers and disorganised wiring.
• Durable construction: the Timer Box Pro range uses a robust metal exterior for long-term use.
• Heater socket version: useful where your grow room setup also needs a dedicated heater connection.

For customers replacing an old Green Power Contactor

If you are replacing a Green Power Contactor, the easiest way to choose your new unit is to match the number of outlets you used on the original contactor. If your previous unit was always full, stepping up to the next size can give you more flexibility for future equipment changes.

• Choose 4-way if you only run a smaller number of lights or want a compact replacement.
• Choose 6-way if you want a balanced option with extra room for expansion.
• Choose 8-way if you run a larger setup or need higher outlet capacity.
