GLH Series HDE-8 Air-Cooled DE Reflector, 315-1000W HID Grow Light Hood

The Growlite GLH Series HDE-8 Air-Cooled Reflector is a high-performance horticultural lighting fixture designed for double-ended (DE) HID lamps. Engineered for commercial grow environments, the HDE-8 delivers superior light uniformity and thermal management to maximize plant growth and overall system efficiency. The fixture features Growlite’s patented Concealed Vacuum Airflow Technology (CVAT), which directs airflow behind the reflector rather than across the lamp. This design improves heat removal while maintaining optimal lamp operating conditions, resulting in enhanced photometric performance and consistent light output. The optical reflector design incorporates a fine hammertone finish that increases reflective surface area and improves light uniformity across the canopy. Combined with CVAT technology, the HDE-8 provides efficient light distribution for coverage areas typically around 4 ft x 4 ft, making it ideal for indoor grow rooms and greenhouse applications. Constructed from heavy-duty 22-gauge steel with a durable powder-coated finish, the fixture is built for long-term reliability in demanding grow environments. A removable door allows for easy lamp access and maintenance, while redesigned sockets simplify re-lamping procedures. The HDE-8 includes four-way, field-selectable 8-inch duct flanges, allowing flexible configuration for fully sealed air-cooled or non-air-cooled operation. This adaptability makes it easy to integrate into a wide range of ventilation and environmental control systems. Designed to operate with 315W to 1000W double-ended HPS or CMH lamps, the fixture supports both standalone reflector configurations and complete systems paired with compatible Growlite ballasts and lamps. The unit is ETL listed for damp locations, making it suitable for humid indoor growing environments. With its advanced airflow technology, durable construction, and high-efficiency optical performance, the Growlite GLH Series HDE-8 Reflector provides a reliable and flexible solution for commercial horticultural lighting applications.
