Professional Grade Grow Light Contactor Timer with Fan Sockets

The Omega MDF Lighting Timer Board is a professional-grade solution for safely controlling your grow lights and fans from one central unit.

Built specifically for high-load grow room setups, it uses an integrated contactor relay system to handle the electrical demand that standard plug-in timers simply can’t cope with.

If you're running multiple lights, this is the safest and most reliable way to automate your setup while keeping everything cle§an, organised and under control.

Key Benefits

• Designed for high-load grow lighting (HID, CMH & LED)
• Built-in contactor safely switches multiple lights
• Grasslin timer included for precise light cycles
• Dedicated fan sockets for constant airflow
• Available in 4, 6 or 8 way models
• Wall-mounted MDF board for tidy installations

Why You Need a Grow Light Timer Board

Standard timers aren’t built for the demands of a proper grow setup. Running multiple lights through a basic timer can lead to overheating, failure or even electrical risk.

The Omega Timer Board solves this by using a contactor relay to safely handle high electrical loads. This protects your equipment while ensuring your lights switch on and off reliably every cycle.

For growers stepping up from a basic setup, this is one of the most important upgrades you can make.

Integrated Fan Sockets – Always-On Airflow

Unlike standard timer setups, the Omega board includes dedicated fan sockets that stay powered 24/7.

This means your extraction and airflow continue running even when your lights are off – helping maintain stable temperature and humidity throughout your grow cycle.

How to Set Up

Mount the Omega MDF Timer Board securely to a wall near your grow setup.

Plug your grow lights into the timed sockets and your fans into the always-on fan outlets.

Set your light schedule using the Grasslin timer and let the system run automatically.
