Omega 4ft T5 108W Propagation Light — Proven Fluorescent Lighting for Seedlings and Cuttings
Best for: Budget-conscious growers starting propagation or scaling up without breaking the bank on energy bills
Our thoughts
This is the sensible choice for propagation. Omega T5 lights are proven performers in independent testing, they run cool enough to sit on a propagator without stress, and they cost a fraction of what you'd spend on LED alternatives. One we sell a lot of for growers just getting started with seeds and cuttings.
The Omega 4ft T5 108W propagation light is a 2-tube fluorescent fixture designed specifically for nurturing seedlings and cuttings without the heat stress or setup complexity of larger grow lights. It's a proper entry-level T5 light that covers the basics properly — proven optics, no ballast needed, and a price that leaves room in the budget for better soil or nutrients. The 6400K cool daylight spectrum is exactly what young plants want during early growth, and the grooved reflector design means zero wasted light.
How it compares
This sits firmly in the entry-to-mid tier of propagation lighting.
- Lower upfront cost than LED propagation systems, with proven reliability
- Significantly cooler running than HID alternatives — safe to position 15-30cm above delicate cuttings
- Outperforms standard T8 systems on light output per watt, with independent UK testing backing Omega's performance
- Daisy-chain ready, so you can connect up to 8 units for larger propagation areas without rewiring
Think of it as the workhorse approach to propagation — no gimmicks, no overheating, just reliable light at a sensible price.
Usage guidance
The Omega T5 works cleanly across different propagation scenarios:
Single propagation tray setup
Position the light 15-30cm above your seedlings or cuttings. Optimal results come at 2-3cm, but keep an eye on heat and leaf stretch. Run on a 16-18 hour photoperiod with 6-8 hours darkness for balanced growth.
Scaling up propagation
Daisy-chain multiple units together — up to 8 fixtures can be linked without additional wiring. Perfect for growers bringing on multiple trays of cuttings or expanding seasonal seed production.
Temperature management
T5 fluorescents emit virtually no heat, making them ideal for enclosed propagation spaces or summer propagation where heat stress is a real concern. You can safely mount them directly on a propagator cabinet.
Running costs
At 108W for two tubes, this costs significantly less to run than HID systems, and the fixture simply plugs into mains — no ballast to source or install.
Technical specifications
- Power output: 108W (2-tube configuration)
- Tube length: 4ft
- Light spectrum: 6400K (cool daylight) — ideal for vegetative growth
- Housing: Durable black metal casing
- Reflector: Individual grooves per tube, optimised light crossover
- Installation: Plug-and-play, no ballast required
- Dimensions: Height 127mm, Length 130mm, Width 410mm
- Daisy-chain capability: Up to 8 units can be connected together
- Tube lifespan: Approximately 10,000–20,000 hours (standard T5 fluorescents)
Who this is for
- First-time propagators wanting reliable, affordable lighting without learning curves
- Growers scaling propagation from single tray to multiple trays on a tight budget
- Anyone in a space with height constraints where cool-running lights make sense
- Experienced growers replacing worn-out T8 systems or old HID setups
- Operators running seasonal seed or cutting production where upfront cost matters
Particularly well suited to hobby and semi-commercial growers prioritising low running costs and minimal heat output over bleeding-edge efficiency.
Our take
This is a solid propagation light that does exactly what it should — delivers the right spectrum, stays cool, and won't rinse your budget or your electricity meter. The grooved reflector and daisy-chain setup mean you've got room to grow without starting from scratch.
End-of-line stock, so you're getting proper proven kit at a much lower price than usual. Good time to buy while clearance stock lasts.
