Sun System Par Pro Commercial Reflector is optically engineered for the high performance Par Pro 1100 watt Hyper Arc High Pressure Sodium lamp. Fabricated, assembled, and designed in the USA. Open reflector design allows light to get closer to the plant canopy. Vented side louvers allow for heat dissipation of the lamp while still maintaining optimal operating temperature. Uniform light pattern is ideal for both crossover, supplemental and primary lighting applications. The small footprint reduces shadowing in open greenhouse/supplemental lighting applications. Designed specifically for the Par Pro 1100 watt Hyper Arc High Pressure Sodium lamp (lamp included) to provide optimal efficiency and uniformity in your commercial environment. The Hyper Arc lamp delivers a staggering 2,380 mol on the Sun System 1 DE 1000 watt turbo setting!
