Omega 120w Under Canopy LED Grow Light - Lower-Canopy Lighting for Bigger Bud Sites
Best for: growers who want to light up the lower and inner parts of the canopy that a single top-down fixture can't reach, to bulk up lower bud sites and reduce wasted growth.
Our thoughts
Under-canopy lighting is one of those upgrades that quietly pays for itself - lower bud sites that would otherwise stay small and airy get proper light, and you stop wasting the growing space under a dense canopy. This bar is slim enough to slot between plants without getting in the way, and at 120W it's a genuine light source rather than a token add-on.
The Omega 120W Under Canopy LED Grow Light is a slim LED bar, just over a metre long (1202mm), designed to sit horizontally within the lower canopy rather than overhead. It delivers a PPF of 340 µmol/s at an efficacy of 2.8 µmol/J, with a wide 110-degree beam angle that spreads light sideways into the gaps a top-mounted fixture leaves in shadow. The result is more even light penetration through the mid and lower canopy, which encourages growth and bud development in areas that would otherwise stay underdeveloped.
It's rated IP66 for protection against dust and moisture, sensible given it sits inside a humid canopy, and runs on an autosensing 120-277V input drawing around 0.6A at 230V. Fixtures can be daisy-chained together, up to 15 units on one circuit, so it scales easily for larger multi-plant setups.
How it compares
Under-canopy or "side lighting" bars are a growing category alongside standard top-down LED fixtures, aimed at filling in shadow rather than replacing the main light.
- Similar under-canopy bars from Lumatek and Maxibright cover comparable ground but often cost more for a similar PPF output
- Against running a second overhead fixture instead, an under-canopy bar targets the actual shaded zones more directly and uses less power to do it
- IP66 rating puts it ahead of basic unrated LED strips that aren't built to handle a humid grow-tent environment
If you're already running a decent main light and want to fix dark lower-canopy zones specifically, this does that job efficiently rather than brute-forcing more light from above.
Usage guidance
Positioning
Mount horizontally within the canopy, roughly level with the mid-to-lower bud sites, angled or clipped so the 110-degree spread covers as much of the shaded zone as possible.
Daisy-chaining
Link up to 15 units together on one circuit using the daisy-chain connectors for larger tents or multi-plant rows, keeping total load within your circuit's rating.
Timing
Run it on the same light schedule as your main fixture rather than as a separate cycle, so the plant isn't getting mixed light signals.
Technical specifications
- Power draw: 120W (+5%)
- PPF: 340 µmol/s
- Efficacy: 2.8 µmol/J
- Beam angle: 110°
- Ingress protection: IP66
- Input voltage: 120-277V autosensing

Who this is for
- Growers running dense, multi-branch plants with shaded lower bud sites
- Anyone supplementing a single top-down fixture rather than replacing it
- Growers scaling up multiple plants who want to daisy-chain several bars together
Best suited as an add-on to an existing main light, not as a standalone grow light.
Our take
This is a genuinely useful supplement rather than a gimmick - real PPF output, a sensible IP rating for tent conditions, and daisy-chaining that makes it easy to scale. It won't replace your main fixture, and it isn't meant to.
Does exactly what it should, day in, day out - a smart, targeted way to get more usable bud sites out of a canopy you're already lighting from above.
