Lumatek 30W Supplemental UV Daisy Chain Cable (1.5 Metre) — Essential Connector for Multi-Bar Setups
Best for: Growers running multiple Lumatek 30W UV supplemental bars who want clean wiring and single-point control
Our thoughts
If you're serious about UV supplemental lighting, you're likely running two bars per Zeus fixture — which means you need this cable. Simple plug-and-play connector that tidies up your rig and lets you power multiple bars from one source. One less thing to overcomplicate.
The Lumatek 30W Supplemental UV Daisy Chain Cable is a 1.5 metre connection lead designed to link multiple Lumatek 30W UV supplemental LED bars in series. Instead of running separate power lines and controllers for each bar, you plug them together and operate from a single power source. It's straightforward kit that reduces cable clutter and simplifies your grow room layout without any fuss.
How it compares
This sits in a specific role — it's not a standalone light, it's the connector that makes multi-bar UV setups practical.
- Daisy chain approach beats running individual power cables (cleaner, fewer controllers needed)
- Proprietary Lumatek design — guaranteed compatibility with 30W UV bars, no guessing
- 1.5 metres gives you flexibility for strategic bar placement across your canopy
- Plug-and-play installation — no soldering, no faffing about
In real terms, this is the accessory that makes running two UV bars (the Lumatek-recommended setup per fixture) actually manageable.
Usage guidance
This cable is designed specifically for linking Lumatek 30W UV supplemental bars:
Basic setup
Connect one bar to your power source, then plug the second bar into this cable. That's it. Both bars run from one controller.
Multi-bar deployments
Lumatek recommend mounting two UV bars per Zeus fixture for full coverage. This cable makes that setup clean and manageable — no rat's nest of separate leads.
Cable routing
The 1.5 metre length is enough to route bars strategically across your canopy while keeping the main lead tidy. Plan your runs before you clip it down.
UV protocol
Once wired, UV exposure should be increased gradually — 15 minutes every two days — while you watch for leaf stress. Start low, work up to your sweet spot (typically 2-6 hours daily in grow tents, up to 12 hours in larger rooms). UV is powerful; respect it.
Technical specifications

Who this is for
- Growers running multiple Lumatek 30W UV bars in a single space
- Anyone using Zeus fixtures (which Lumatek recommend pairing with two UV bars per unit)
- Growers who want to add UV supplemental lighting without tangling themselves in cables
- Operators scaling UV setups and adding bars incrementally
- Anyone investing in supplemental UV to boost plant quality during flowering
Essential for growers serious about supplemental UV, pointless for single-bar setups.
Our take
This is a simple, unglamorous cable that does exactly one job — connect your bars cleanly. If you're buying a Lumatek 30W UV bar and planning to run two per fixture (which is the sensible approach), you need one of these. Don't run separate power lines when a daisy chain sorts it properly.
Worth picking up alongside your UV bars. Stock clearance-priced, so good time to grab one while it's available.
