Lighting Science Group Corporation announced that Lighting Science Definity(TM) LED lamps were chosen for installation in the Sioux City Public Museum to help bring the museum galleries into the modern era during a recent retrofit operation. The new technologies installed versus traditional halogen technology, the museum will be saving 110,760 kWh annually. The museum needed to upgrade their facilities, including their lighting, in their newly refurbished home, a re-purposed J.C. Penney Department Store. To provide the best solution, Hilferty decided on Lighting Science's Definity PAR38 and MR16 LEDs, best known for their superior lighting quality and energy efficiencies, to meet the lighting design needed to suit the architectural style of the building. The Definity PAR38 and MR16 are robust LED lamps from Lighting Science that reduce energy consumption and operating costs by up to 80% and offer maintenance-free operation that lasts up to 25 times longer than conventional lighting. The patent-pending optical design achieves smooth beam pattern to achieve a warm room-filling glow for general illumination applications with the instant on lamps dimmable to 5% of light on most dimmers. By using a variety of beam angles and warm white color temperature from the Definity lamps, the museum exhibits now capture the attention of viewers as intended and creates areas that truly engage visitors.
