Lumatek 30W UV Power Cable (4 Metre) — Supplemental UV Lighting Accessory for Zeus Fixtures
Best for: Growers running Lumatek Zeus fixtures who need a reliable power cable for 30W UV supplemental LED bars
Our thoughts
If you're adding UV supplementation to a Zeus setup, this cable does exactly what it should — connects cleanly, reaches properly, and lets you position your UV bar where it needs to be. Four metres is enough slack for most grow room layouts without the mess of excess cable.
The Lumatek 30W UV Power Cable is a purpose-built accessory that connects your Lumatek 30W UV supplemental LED bar to mains power (220/240v). Featuring M12 3-pin connectors with Schuko connection, it's designed for the Zeus fixture ecosystem and ships at four metres — enough reach for flexible positioning without overcomplicating your setup. This is professional-grade lighting accessory kit, straightforward and built to last.
How it compares
This is a specification-matched cable for Lumatek's UV supplemental system.
- Purpose-built for Zeus fixtures — no compatibility guessing
- Heavy-duty M12 connectors rated for professional use
- Four metres gives you genuine flexibility; longer than most generic grow light cables
- Lumatek backing — professional pedigree, backed by a 5-year warranty on the ecosystem
If you're building a Lumatek system, this is the cable to use. It's not the cheapest generic option, but it fits the job properly.
Usage guidance
This cable powers your Lumatek 30W UV supplemental LED bar across the flowering stage of your growing cycle.
Installation
Unscrew the protective cap on the male connector end. Push firmly into the female socket on your UV LED bar until it seats completely. The four-metre length gives you space to run the cable neatly alongside your main light cables or tuck it along the grow frame.
Timing and placement
UV supplementation works best during flowering, starting at least four weeks before harvest. Position your UV bar using the cable length to achieve even coverage across your canopy — typically one to three UV bars per Zeus fixture depending on the model (300W to 1000W+).
Power requirements
Runs on standard 220/240v UK mains. The integrated power supply in the LED bar handles voltage regulation. Turn off power before installation or maintenance.

- Professional or commercial operations using modular Lumatek systems
This works best if you already understand what UV supplementation does and have a Zeus fixture to connect it to. It's not an entry-level product — it's a professional accessory for a professional lighting system.
Our take
This is a proper cable for a proper system. Lumatek knows what they're doing with professional lighting, and this cable is built to match that standard. If you're running Zeus and want to add UV bars, this is the right choice — it fits, it works, and it's backed by people who've been in the game since 2004.
Good time to buy if you're scaling up your Zeus setup. One cable connects one bar; daisy-chain cables are sold separately if you're running multiple units.
