Maximize yield in tight spaces with 600W HPS power at just 330 watts.

The HLG 350 Diablo is a powerful, high-efficiency LED grow light designed to replace a 600W HID using only 330W. Featuring two Advanced Design Diablo Quantum Boards, this grow LED light delivers full-spectrum white light with deep red (660nm) for optimal plant growth and flowering. Its rectangular footprint and integrated reflectors ensure even light coverage, making it ideal for flowering in smaller grow spaces or vegging in commercial setups.

Is the HLG 350 Diablo Energy-Efficient?

Absolutely. With an efficacy of 2.80 µmol/J, this fixture outperforms traditional HID systems (1.3–1.7 µmol/J), delivering more usable light per watt while lowering power costs. Backed by a 5-year warranty and UL 8800, CSA, and DLC certifications, the HLG 350 Diablo is a top choice for serious growers looking to maximize efficiency and yield.
