120W Samsung LM281B LED Grow Light

3 Year Warranty

Unlock commercial-grade plant growth with the 120W Full Spectrum LED Grow Light, engineered for serious growers who demand maximum yields, uncompromising efficiency, and long-lasting reliability. Powered by high-performance Samsung LM281B and San’an diodes, this fixture outshines generic LEDs with 600 diodes, advanced drivers, and precision spectrum blending for vigorous growth from clone to harvest.

Maximum Efficiency: Industry-leading efficacy of 2.6 µmol/J and PPF of 312µmol/s, delivering more usable light per watt for explosive plant growth.

Unrivaled Longevity: Built to run 50,000+ hours with minimal drop-off in brightness - 95% output after two years, compared to only 60% for most budget lights.

Full Spectrum Performance: Scientifically tuned ratio of 3000K + 5000K white, and deep 660nm red, promoting rapid germination, explosive vegetative growth, and flower density.

Superior Diode Count: 600 diodes - 2x more than most competing 120W grow lights - means more light uniformity, higher intensity, and deeper canopy penetration.

Professional-Grade Components: Robust AISHI capacitors, oversized MOS tubes, USA microchip IC, and built-in premium LED driver ensure safe, silent, and reliable operation.

Advanced Features for Growers

Dimmable & Daisy-Chainable: Effortlessly adjust intensity from 0–100% and link multiple fixtures with RJ14 control for seamless commercial installations.

Four-Bar Passive Cooling: Aluminum frame and passive thermal management keeps temperatures low, extending diode and driver life without noisy fans.

Balanced Light Spread: 120° beam angle and four-bar array guarantee even coverage—no hot spots, no wasted energy.

Engineered for Maximum Yield

Cannabis Optimized: Designed for propagation, vegetative, and flowering cycles - proven to boost yield by up to 30% vs. basic LEDs.

Perfect for Small Tents & Vertical Racks: Ideal for 60x60cm to 80x80cm tents, clone rooms, seedling racks, or as a high-efficiency supplement in larger commercial canopies.

Plug-and-Play: Lightweight (4kg), easy to hang, and simple to integrate into any system - hydro, soil, coco, or aquaponics.
