Vibrant colored lighting minimizes energy consumption, heat load on fragile artifacts
Largo, Florida (October 16, 2012) – France’s natural history museum has renovated its lighting system to include SeaChanger’s Light Emitting Plasma (LEP) Color Engines, citing the product’s incredible color palette and high-energy efficiency.
The Grande Galerie de l’Evolution of the Muséum National d’Histoire Naturelle in Paris has origins dating back more than 375 years. Its previous lighting system had extremely high maintenance and daily use costs, said Pierre de Cazenove, the museum’s head of operations and planning for exhibits. The move to SeaChanger LEP is part of the museum’s effort to conserve energy and use long-lasting light sources that won’t harm delicate museum pieces.
SeaChanger’s color engine, designed to be utilized with ETC Source Four optical components, provides professional lighting for theaters, museums and architectural installations around the world. The LEP can crisply illuminate the museum’s artifacts from throw distances of 35 meters, a range not reachable by LED products without significant loss of illumination. The SeaChanger Plasma’s light source puts out low ultraviolet and infrared light that does not damage the displays, and its energy-efficient plasma source reduces energy consumption and heat load, a necessity when displaying artifacts dating back to the late 1600s.
“Light Emitting Plasma is a real alternative to conventional light sources: halogen, LED or discharge lamps,” said Jean Louis Pernette, managing director of AVAB, a SeaChanger and ETC distributor. “The compromise between light output, power used and lamp life is unique and perfectly meets the museum’s specifications.”
The museum illuminates some of its biggest attractions with SeaChanger LEP such as its large caravan of African animals; desert, marine and polar spaces; and a whale skeleton. The museum is continuing to convert its lighting to SeaChanger units. When complete, savings will total more than $38,000 per year because of infrequent re-lamping and reduction of electricity consumption.
SeaChanger’s Light Emitting Plasma 320-watt lamp produces 10,000 lumens of light performing at more than 31 lumens per watt with a lamp lifespan of 15,000 hours. It is convection-cooled and silent, with smooth, swipe-free color transitions and a color rendering index of 92. The dichroic filters provide better color re-creation than colored LEDs that will color degrade over time, and their resistance to temperature and humidity assures color consistency for the life of the fixture.
SeaChanger will present its products in Booth #1113 at the LDI 2012 show in Las Vegas from Oct. 19 to Oct. 21.
