If you're running a 2x2 tent, a small trial room, or testing a new SKU before you commit to a bigger order, this 120W LED grow light panel is built for exactly that job. It's a compact, single-board panel LED grow light using Samsung LED diodes, delivering a PPF of 350umol/S at an efficacy of 2.9umol/J - numbers that hold up against panels twice its price. Built on quantum board technology, it packs even, full-canopy coverage into a low-profile footprint.
It's engineered for growers and distributors who need consistent output, real test data, and a supplier who can customize the build to spec.
Products Features
A lot of small-format panels cut corners on efficacy to hit a low price point. This one doesn't. At 2.9 umol/J, this 120W LED grow light panel sits at the upper end of what current LED panel technology can deliver - most budget 120W boards on the market land closer to 2.3–2.6 umol/J, which means growers need more watts to achieve the same light output.
- 6063 aluminum alloy housing - thick-wall extrusion for passive heat dissipation, no fan noise, no moving parts to fail
- IP65 waterproof joint on the power connection - built for humid tent environments, not just dry lab conditions
- 120° beam angle for even canopy coverage in tight 2x2 footprints
- Lightweight, simple design - 1.75kg makes it easy to hang, ship, and stock

PPFD Test Data
We physically test PPFD point-by-point rather than relying on simulated output. Here's the real measured data for this LED grow light panel at three mounting heights, tested over a 1200x1200mm area.
At 30cm, canopy-center PPFD comfortably supports flowering-stage light requirements; at 60cm, output is still strong enough for vegetative and seedling stages across a full 2x2 footprint. This makes the 120W a genuine full-cycle option, not just a veg light.

Smart Dimming & Networkable Control
This panel isn't limited to a manual knob. It's built with a network port, so it integrates into commercial control systems - useful if you're deploying multiple units across a grow room and want centralized dimming rather than adjusting each fixture by hand. The 0–10V dimming range gives fine control for matching output to plant stage without swapping fixtures.
Customization - OEM/ODM Available
We manufacture this line to spec, not just off a fixed catalog.
- Colors: gold, green, or blue anodized aluminum housing
- Diode options: Samsung 281B, 301B, 301H, or 301H EVO - tell us your target spectrum and efficacy goals and we'll match the chip
- Branding: custom logo, custom packaging
- MOQ: 50 units for OEM/ODM orders
If you're a distributor or brand building out a product line, this is where the 120W panel earns its keep - same core quantum board engineering, dressed to your spec.
FAQ
Q: What tent size does a 120W LED grow light panel cover?
A: At standard hanging heights, it's sized for a 2x2 tent, with strong PPFD readings from 30cm through 60cm above canopy.
Q: Is this LED grow light panel dimmable?
A: Yes, it has a 0–10% dimming signal and supports network-based control for multi-unit setups.
Q: Can I get this 120W LED grow light panel in a custom color or with my own branding?
A: Yes. Gold, green, and blue housing colors are standard, and full OEM/ODM branding is available starting at 50 units.
Q: What's the difference between this and a 100W LED grow light?
A: 120W is our standard entry point in this panel series - it runs at a higher PPF (350umol/S) than most 100W boards on the market while keeping the same compact 2x2 footprint.
