GrowPros HM240 LED Grow Light




HM240 Series

Operating at only 240W, the Grow Pros HM240 Series is an LED rack lighting solution designed for commercial indoor and greenhouse applications, enabling control over the plant cycle, specifically optimized for the vegetative stage. The HM240 Series, a 2×4 rack light solution, with an increased lifespan over traditional grow light sources, cultivates healthier, happier plants.

Performance Data

The HM240 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 HM240 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 HM240 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 HM240 lighting system is a complete, pre-assembled LED grow light that lowers installation time with a wide range of wiring techniques and connectors. The HM240 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.
