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 fixture 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. With an impressive efficacy of 2.80 PPF/W, this fixture maximizes yield while reducing energy consumption.
