GLH Series OG Air-Cooled Reflector, 315-1000W HID Grow Light Hood

The Growlite GLH Series OG Air-Cooled Reflector is a high-performance horticultural lighting fixture designed for single-ended HID lamps. Engineered for commercial and indoor grow environments, the OG Series combines advanced airflow technology with superior optical performance to maximize plant growth and overall system efficiency. The reflector features Growlite’s patented Concealed Vacuum Airflow Technology (CVAT), which eliminates open duct holes and utilizes 100% of the reflective surface. This design increases reflective area by approximately 30% compared to traditional air-cooled reflectors, delivering improved light output and more uniform canopy coverage. A vertical lamp orientation enhances photometric performance and extends lamp life by reducing stress and maintaining consistent operating conditions. This configuration also improves light penetration throughout the plant canopy, promoting more consistent growth and higher yields. The OG Series includes removable 8-inch duct flanges and louvered plates, allowing flexible configuration for air-cooled or passive ventilation setups. This adaptability improves airflow efficiency and enables multiple reflectors to be integrated into larger grow systems using fewer fans. Constructed from heavy-duty 22-gauge steel with a durable powder-coated finish and tempered glass lens, the reflector is built for long-term reliability in demanding grow environments. A hinged or removable door provides easy access for lamp replacement and maintenance. The fixture supports a wide range of lamp types, including high-pressure sodium (HPS) and metal halide (MH), with wattage options from 315W up to 1000W. Typical coverage areas are approximately 4 ft x 4 ft, making the OG Series suitable for grow rooms, greenhouses, and indoor cultivation systems. With its patented airflow design, durable construction, and high-efficiency optical performance, the Growlite GLH Series OG Reflector provides a dependable solution for maximizing light output and plant productivity in horticultural lighting applications.
