Omega Contactors — UK-Built Heavy-Duty Lighting Controllers for HID Control
Best for: Growers running multiple HID lights who need serious electrical protection and precise light cycle timing
Our thoughts
If you're running HPS or HID lights without a proper contactor, you're playing with fire — literally. Omega's UK-assembled units do one job and do it properly: absorb the electrical surge that kills standard timers. Built from solid components, minimal fuss, no marketing fluff. This is the kind of thing you buy once and forget about.
Omega Contactors are heavy-duty relay switching units designed to safely control HID lighting systems in grow rooms. They exist to solve a specific, critical problem: when HPS or HID lamps fire up, they create a massive electrical spike that destroys cheap timers. An Omega contactor sits between your timer and your lights, absorbing that surge so your timer stays alive. Available in 2, 4, 6, and 8-way configurations, they're built in the UK from proper components and backed by years of proven use in commercial growing.
How it compares
Omega sits in the mid-to-premium tier of UK-made contactors.
- Same UK manufacturing standard as Maxibright and Green Power, without the premium pricing
- Built from agricultural-grade components — not budget relay boxes
- Minimal heat output and rubberised plugs make installation straightforward
- Price-competitive against equivalent Maxibright units; less feature-heavy than models with integrated heater sockets
In short: professional-grade electrical protection at a fair price. No bells, no whistles, no dead timers.
Usage guidance
Single HID light setups
A contactor protects your timer from initial surge damage. Even with one light, it's worth doing properly.
Multiple HID lights (2–8 lamps)
This is where a contactor becomes essential. Running 2 x 600W, 4 x 600W, or 6 x 600W through a standard timer will blow the internal contacts within weeks. An Omega unit absorbs the collective surge, keeping your timer and your schedule safe.
Installation
Mount using the included hanging bracket. Plug your timer into the contactor's input socket. Plug your lights into the contactor's output sockets. Set your timer as normal — the contactor does the heavy lifting silently in the background.
Ongoing use
Set it and forget it. The contactor produces minimal heat, so ventilation isn't a concern. Rubberised plugs stay secure under repeated switching.

Our take
A contactor isn't glamorous, but it's the difference between a stable lighting schedule and a dead timer halfway through a cycle. Omega's UK-built units do exactly what they should: absorb the surge, protect your kit, and last years without complaint.
If you're running multiple HID lights, this is essential equipment. Good time to buy while stock lasts.
