Engineered for commercial-grade cannabis cultivation, this 720 W LED Grow Light uses Samsung LM281B horticultural diodes to create a precisely tuned full-spectrum array that drives explosive growth, dense flowering, and resin production. Delivering up to 2.9 µmol/J efficacy and a PPF output of 2 088 µmol/s, this 6-bar fixture produces professional results at a fraction of traditional HPS power costs.
Performance & Efficiency
High Output, Low Power Draw: Rated at 2.9 µmol/J - achieving >30% energy savings over HPS and lower-tier LEDs.
Massive Photon Flux (PPF: 2 088 µmol/s): Uniform canopy coverage for rapid, high-density flower development.
Full Spectrum + 660 nm Red: Scientifically balanced 3000 K + 5000 K + 660 nm wavelengths enhance vegetative vigor, bud size, and cannabinoid/terpene content.
2016 Diodes: 954 × white (5000 K) + 990 × warm (3000 K) + 72 × deep-red (660 nm) for optimal PAR distribution.
Design & Durability
6-Bar Layout: Ensures even light intensity with minimal hotspots, maintaining consistent PPFD across the canopy.
Built-In Driver: It's integrated driver system (AISHI capacitors, high-grade MOS tubes, microchip IC) ensures stability, low heat, and long lifespan.
Passive Cooling: Aluminum housing dissipates heat silently - no fans, no noise, no maintenance.
IP65 Waterproof & Dustproof: Ideal for humid grow rooms, greenhouses, and hydroponic environments.
Smart Control Ready
RJ14 Port Compatibility: Connect up to 200 lights via the Light Controller (sold separately).
Wi-Fi & 4G Integration: Enables remote scheduling, dimming, CO₂, and temperature sensor automation for precise cultivation control.
0–10 V Dimming: Adjust output to match each growth stage - seedling, veg, or bloom — without losing efficiency.
Ideal For
Professional cannabis growers targeting higher THC and terpene expression.
Commercial greenhouses and indoor facilities.
Advanced home growers seeking commercial-grade results.
