HLG 600 R-Spec LED Grow Light by Horticulture Lighting Group

HLG 600 R-Spec Quantum Board LED Replacing 1,000W HID

The HLG 600 R-Spec uses 4 custom-designed quantum boards loaded with Samsung LM301H diodes and Deep Red 660nm LEDs to deliver 1,522 PPF at 2.60 µmol/J efficacy. Dimmable from 60 to 600W via the included MeanWell power supply, this fixture covers a 5 x 5 ft flowering footprint at 30 in and a 7 x 7 ft veg footprint at 48 in. The auto-sensing driver works on 100-277 VAC without manual switching, and the entire unit measures 26 x 21.5 x 2.75 in at 15 lbs.

Samsung LM301H Quantum Boards with 660nm Red and Passive Cooling

Passive cooling across the quantum board surface area eliminates fans and their associated noise, while the diffused light output improves canopy penetration compared to point-source fixtures. The R-Spec variant builds on the legacy of the HLG 550 V2 R-Spec with newer Samsung diodes and an optimized spectral blend for flowering applications. Certifications include UL 8800, UL 1598, and CSA, backed by a 3-year warranty.

Key Features

• 1,522 PPF at 2.60 µmol/J: Strong photon output from high-efficiency quantum boards for dense flowering canopies
• Samsung LM301H + 660nm Deep Red: Full spectrum white light enhanced with deep red drives flowering response and generative growth
• Dimmable 60-600W: Wide dimming range covers every growth stage from seedling propagation to peak flower
• Auto-Sensing 100-277 VAC: MeanWell driver detects input voltage automatically for plug-and-play flexibility across facilities
• Passive-Cooled at 15 lbs: No fans, no noise — reliable thermal dissipation across the quantum board surface at a manageable weight
