The shape of the Blazer� DE Reflector is perfect for square growing areas. Highly reflective aluminum offers excellent output, reflectivity and diffusion. Made specifically for double-ended horticulture lamps (not included). German made, UL listed double-ended sockets. Unique double-ended construction allows for maximum optical efficiency and uniformity. Improved spectrum DE lamps used in this fixture focus on the red component for increased photosynthetic response. They offer improved PAR values and increased PAR/Lumen maintenance (up to 90% PAR at 10,000 hours of operation). Deep reflector design holds the lamp heat to keep the DE lamp at optimal operating temperature. Galvanized steel housing with durable powder-coated finish. Includes pre-wired sockets and 15 ft lamp cord.
