The Silver Sun® DE by Sun System® is a large traditional multi-leaf parabolic hood design that delivers broad coverage using the double-ended platform (not included). Features 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. Made from highly reflective aluminum. Large size provides for a large coverage area even when placed close to plants. V-strike bend above lamp to increase performance. Comes unassembled and easily sets up in minutes. Pre-wired with 15 ft lamp cord and socket.
