The HLG 135 Rspec LED Grow Light Kit combines Samsung LM301H white LEDs and Osram SSL deep-red LEDs for compact indoor vegetative and flowering spaces. This is an unassembled kit: the Quantum Board, heatsink, driver, and wiring components must be assembled before use.

Compact full-cycle lighting

The included specification sheet recommends a 2 × 2-foot flowering footprint, with a maximum listed flowering footprint of 2 × 3 feet, or a 3 × 3-foot vegetative footprint. Actual coverage depends on mounting height, crop requirements, and the target light level. The passive-cooled design uses a separate finned heatsink, with a listed adjustable power range of 60–150 watts.

Assembly and installation

Assembly and electrical connections are required; this is not a ready-to-hang, prewired fixture. Follow the manufacturer's assembly instructions for board mounting, heatsink installation, driver wiring, suspension, and adjustment. Match the power cord and installation to the electrical supply, and have a qualified installer handle electrical connections if needed. Sold as one kit.
