4Seasons Under-Canopy 120w LED Grow Light

Maximize your yields and unlock the full potential of your lower canopy with the 4Season 120W Under Canopy LED Grow Light. Designed specifically for flowering applications, this high-efficiency fixture delivers targeted supplemental lighting beneath your canopy—boosting bud development, density, and overall crop quality.

Engineered with a specialized flowering spectrum (FLOWER FR), this light enhances photosynthetic activity where traditional top lighting can’t reach. The wide 150° beam angle and V-shaped LED layout ensure deep penetration and even light distribution across lower plant sites, helping eliminate underdeveloped growth and increasing total yield.

With an output of up to 360 µmol/s and an efficacy of 3.0 µmol/J, this fixture delivers powerful performance while remaining energy efficient. Passive cooling and a robust aluminum build ensure reliable operation, while the IP65 waterproof rating makes it ideal for high-humidity grow environments.
