Built for serious growers seeking commercial-grade performance in compact spaces, the 240 W LED Grow Light delivers premium efficiency, uniform PPFD, and balanced full-spectrum output powered by Samsung LM281B horticultural diodes. Perfect for tents, propagation areas, or small grow rooms, this 4-bar fixture combines 2.9 µmol/J efficacy with exceptional reliability and plug-and-play simplicity.

Performance & Efficiency

High Output, Low Power Draw: Delivers 624 – 896 µmol/s PPF while consuming only 240 W of power (≈ 30 % energy savings vs HPS and budget LEDs).

Full Spectrum for All Stages: Balanced 3000 K + 5000 K white with 660 nm deep red for vigorous vegetative growth and dense, resinous flowers.

High-Efficiency Driver: Built-in driver ensures steady power delivery and thermal stability for long lifespan and quiet operation.

1200 Diodes Total: 576 × white (5000 K), 576 × warm (3000 K), and 48 × 660 nm reds for a uniform PAR distribution across the canopy.

High Efficacy: 2.6 – 2.9 µmol/J for impressive grams-per-watt performance.

Design & Durability

4-Bar Layout: Even light coverage without hot spots, ideal for 0.9 × 0.9 m to 1.2 × 1.2 m grow spaces.

Passive Cooling: No fans = zero noise and low maintenance.

IP65 Waterproof: Fully sealed for humid grow tents and hydro environments.

Built to Last: > 50 000 h L90 rating with less than 10 % light degradation over time.

Easy Installation: Lightweight form factor (≈ 4 kg) with rope hangers and standard power cord included.

Smart Control Ready

RJ14 Port Compatibility: Connect up to 200 lights via a Grow Light Controller (sold separately).

Wi-Fi & 4G App Control: Integrate with CO₂, temperature, and lighting sensors for automated precision control.

Dimming: 0 – 10 V dimming range lets you dial intensity from seedling to flower without spectrum shift.

PPFD & Coverage

Optimized PAR Mapping: Achieves > 1000 µmol/m²/s at 15 cm for flowering and balanced intensity at all heights.

30 % Yield Increase: Uniform light penetration promotes consistent node development and larger buds across the canopy.

Recommended Coverage: 0.9 × 0.9 m for flower / 1.2 × 1.2 m for veg.

Ideal For

Indoor cannabis cultivators seeking premium results on a budget.

Small grow tents, clones, seedlings, and veg areas.

Commercial facilities requiring supplemental or edge lighting.
