Omega Black 720W LED Grow Light — Budget Bar LED for 1.2–1.5m² Spaces
Best for: Growers switching from HPS to LED on a tight budget, or anyone upgrading to a proper high-output bar light without the premium price tag
Our thoughts
This is genuinely good value. You're getting 720W of proper, efficient light at roughly half what you'd pay for comparable bar LEDs. The ballast compatibility angle is smart too — if you've already got an Omega HPS ballast lying around, you can grab the fixture alone and save even more. Does exactly what it should without the faffing around.
The Omega Black 720W LED is a full-spectrum bar-style LED grow light that delivers professional-grade performance at a fraction of the cost of competing fixtures. Upgraded to achieve 3.2 μmol/J efficiency with a total PPF output of 2304 μmol/s, it's one of the best-value high-output LEDs on the UK market. Designed for growers making the switch from traditional 1000W HPS systems or anyone building a budget-conscious setup, this is proper kit that covers the basics thoroughly and won't rinse your budget.
How it compares
The Omega Black sits firmly in the budget-to-mid-range of 720W bar LEDs.
In plain terms: you're getting light output and efficiency that punches well above its price point.
Usage guidance
The Omega Black is straightforward to set up and operates cleanly across different growing scenarios.
Installation
The fixture arrives pre-assembled and folded in half (it folds at the central hinge, so it fits through loft hatches or tight doorways). Unfold it, fit the included mounting brackets to the two central bars, and connect to your Omega Black 600W digital HPS ballast. Takes minutes, no specialist tools needed.
Space coverage
Best suited to grow tents and spaces between 1.2–1.5 square metres. The bar design creates an almost perfectly uniform footprint — you get flat, even canopies with no hotspots or dead zones. Exactly what you want for reliable results.
Spectrum and flowering
The light output is rich across the full spectrum, but particularly heavy in the red wavelengths. This is intentional — red-heavy spectrums perform brilliantly in the flowering phase, supporting density and structure without overcomplicating your setup.
Dimming and power management
The fixture is dimmable, running anywhere from 250W (quarter power) up to 720W (Super Lumens mode). This gives you flexibility if you're vegging or managing heat in warmer months. Controlled via the ballast, so no extra kit needed.
Heat and energy efficiency
At 3.2 μmol/J, very little energy is wasted as heat. This means your grow room stays cooler and easier to manage, and your electric bills stay lower. In practice, you're replacing a 1000W HPS system with 720W of LED while getting more usable light to your plants — that's a real win.

Who this is for
- Growers making the jump from HPS to LED on a budget — especially those with existing Omega ballasts
- First-time high-output LED buyers wanting to avoid premium brand markup
- Anyone running a 1.2–1.5m² tent who needs proper, even coverage without overspending
- Growers focused on flowering performance and spectrum optimization without the fuss
- Deal hunters and value-conscious operators who want reliability over brand recognition
Particularly well suited to small commercial growers, serious hobbyists, and anyone replacing a 1000W HPS system where the cost difference actually matters.
Our take
This is a solid, efficient 720W LED at a price that makes real sense. It's not the flashiest fixture on the market, but it does exactly what it should — delivers even light, runs cool, saves you money on electric, and gives you years of reliable use. The ballast compatibility is a genuine bonus if you've already got Omega kit.
If you're building a budget setup or upgrading from HPS without spending house money, worth picking up.
