The Grand Master LED (GML) Volcano Under Canopy Light is a high-efficiency side or under-canopy LED lighting solution designed to maximise lower canopy development and increase overall yield and quality in dense grow spaces.

Each Volcano light delivers an impressive 3.21 µmol/J efficacy and 385 PPF total output, penetrating deep into plant canopies where traditional top lights struggle to reach. The system is optimised for 4x4 or 4x5 flowering footprints, making it perfect for commercial facilities and advanced home growers aiming for uniform light distribution and higher-quality bottom buds.

This kit includes 2 x Volcano 120W lights, along with everything you need for a fast and flexible installation — whether used as under-canopy lighting or mounted on the side of vertical racks or tents. The unit is ETL Listed and IP66 waterproof rated for long-term reliability in demanding grow environments.

Ideal for supplementing top lighting in high-density gardens and improving the yield and quality of lower flower sites.
