December 15, 2010—Hubbell Lighting, a division of Hubbell, Inc. and a market leader in lighting technology for over a century, and its Columbia Lighting brand were chosen for a major lighting fixture installation at the Everett McKinley Dirksen United States Courthouse in downtown Chicago, Illinois.
Working closely with the noted New York headquartered lighting design firm, Domingo Gonzalez and Associates (DGA), Columbia Lighting crafted a custom 12″ wide x 48″ long surface-mounted fluorescent fixture and an 8″ wide x 48″ long recessed fluorescent fixture, both built to the Gonzalez firm’s specifications.
Illuminating offices, courtrooms, hallways, stairwells and conference rooms in virtually the entire 30-story glass and steel edifice located in the heart of Chicago’s downtown business district, the new fixtures were specifically designed by DGA to emulate the character and general appearance of the original fixtures in place since the building was completed in 1964.
The new fixtures include modified optics to improve energy efficiency, T8 lamps, and dimming ballast technology. The glass lenses of the original design are being replaced with white parabolic baffles optimized for minimal glare but maximum lumen output.
The original lighting fixtures employed two 40W T12 lamps powered by magnetic ballasts. By comparison, the new energy efficient Columbia replacement fixtures employ a single 32W T8 lamp powered by a Lutron Ecosystem electronic dimming ballast tuned to desired footcandle and energy levels. The T8 lamp is estimated to have a 40,000 hr. lamp life.
Hubbell Lighting, Inc., one of the largest lighting fixture manufacturers in North America, provides a full range of indoor and outdoor lighting products serving the commercial, industrial, institutional, and residential markets. For more information, see the Web site.
