Omega MDF Lighting Timer Boards with Fan Sockets — Professional Contactor Control at Sensible Money
Best for: Growers running multiple HID or LED lights who want safe, centralised power management without the premium price tag
Our thoughts
This is industrial-grade electrical control dressed up in accessible pricing. Same Grasslin timer and 40-amp contactor tech you'd find in boards costing twice as much, but Omega's kept the cost honest. One we recommend constantly for growers stepping up from single-light setups to multi-light rooms.
An Omega MDF Lighting Timer Board is a wall-mounted contactor control system designed to safely manage multiple grow lights and keep your extraction running 24/7. Built around a professional-grade Grasslin mechanical timer and industrial contactors, it eliminates the chaos of extension leads and power cubes, giving you one centralised hub where every plug, every circuit, and every switch sits exactly where you need it. Whether you're powering four lights or a full eight-light setup, these boards handle the load properly — no power surges, no blown fuses, no guessing.
How it compares
Omega sits in the professional-affordable tier of contactor timer boards.
- Same core components as premium brands — Grasslin timer, 40-amp contactor — at significantly lower cost
- MDF backing keeps the price accessible without compromising safety or performance
- Available in 4, 6, 8-way, 12-way, 16-way, and 24-way configurations — scalable for any room size
- Split-circuit design (timed lights + constant-power fans) solves the real problem of managing different equipment lifecycles
In short: you're getting the electrical protection and timer reliability of professional boards at a price that doesn't require a second mortgage.
Usage guidance
Installation and operation break down simply:
Wall mounting and setup
The board wall-mounts near your grow space. Plug your lights into the timed sockets, your fans and extraction into the constant-power (aux) sockets, and set your light cycle using the Grasslin timer. That's it. Individual on/off switches on each socket let you control equipment independently.
Light cycle management
The 24-hour Grasslin timer operates in 15-minute increments, giving you precise control over your photoperiod. Set it once and it repeats daily — no manual switching, no human error, no light-burn risk from accidental switches left in the wrong position.
Fan and extraction control
Fan sockets remain live 24/7, independent of the timer. Your extraction, intake, and climate control run continuously while your lights follow your programmed schedule. This separation of circuits is deliberate — it's how professional rooms work.
Electrical safety
The 40-amp contactor handles the switching load that would kill a standard domestic timer or extension lead. No power surges, no relay chatter, no risk of tripping. The board comes with its own breaker fuse for added protection. Installation must be carried out by a qualified electrician.

Who this is for
- Growers stepping up from single-light setups to 4+ light operations
- Anyone running HID, CMH, or high-output LED systems who wants professional-grade control
- Rooms where centralised power management matters — safety, tidiness, and ease of use all at once
- Budget-conscious growers who refuse to compromise on electrical protection or timer reliability
- Professional and semi-professional operations where equipment reliability is non-negotiable
Particularly suited to growers tired of juggling extension leads, worried about power surges, or simply wanting their grow room to look and operate like it's been thought through.
Our take
This is proper electrical control for multi-light operations without the proper-price tag. The Grasslin timer and contactor tech is identical to boards costing significantly more — Omega's just refused to inflate the price because of the brand name or plastic housing.
If you're running four lights or more and managing them with domestic timers or extension leads, this is a genuinely smart upgrade. Safe, reliable, and built to work day in, day out. Good time to buy while clearance stock lasts.
