CONSIDER YOUR POCKETBOOK

When selecting site lighting products, three important cost factors should be evaluated—fixture construction, energy consumption and maintenance cycle. Corrosive moisture, broad temperature variation and flocking insects make the outdoor environment particularly challenging for optimal luminaire performance. Premium materials and precisely toleranced construction allow site lighting products to perform efficiently with minimal maintenance. Cooper Lighting uses silicone gasketing, enhanced TGIC powder coat paint and premium reflector materials to ensure the highest level of photometric performance and unwavering endurance over the fixture’s installed life.

In addition to luminaire construction, light source selection can dramatically impact the operating and maintenance costs of the lighting system. Pulse Start Metal Halide technology is being embraced for its efficiency, extended life, high lumen maintenance and color consistency. The increased color rendering index [CRI] of pulse start lamps improves visibility and heightens the overall safety and security of the site. Higher lumen maintenance reduces the number of fixtures needed to achieve a consistent illuminance level over the fixture’s installed life. Initial savings are compounded by decreased energy consumption and less frequent maintenance intervals. By supporting a full array of both horizontal and vertical lamp positions, Cooper Lighting’s outdoor luminaire portfolio offers the broadest selection of energy saving pulse start solutions.
