HM660 Series

The HM660 is a full-spectrum LED rack lighting solution designed for commercial indoor and greenhouse applications, enabling control over the plant cycle from the vegetative stage to the flowering stage. Indoor plants grow best under full-spectrum lights, which replicate the natural spectrum of the sun. The HM660 Series, with an increased lifespan over traditional grow light sources, cultivates healthier, happier plants.

Performance Data

The HM660 Series produces 1.8 gram per watts (dried) of crop yield. A high-PPFD and PAR indicates high efficacy, or light output produced per expenditure of unit of power. Generating about 50% more in energy savings over traditional HID and HPS light sources, the HM660 gives you meaningful savings over time. Will not produce the same results without CO2 supplementation. cULus Listed; Dry and Damp Location Rated; 7-Year Warranty.

The HM660 Advantage

Better control of environmental and production factors means higher yield and multiple harvests in one growing season. No wasted energy: Almost 100% of power expended converts into growth-targeted light energy. The HM660 lighting system is a complete, pre-assembled LED grow light that lowers installation time with a wide range of wiring techniques and connectors. The HM660 Series system runs cool thanks to a passive cooling thermal management system, meaning your lighting systems last longer while retaining high light output levels. Longer lifespan means you can grow crops for many years without needing to replace the lighting system, reducing costs.
