The Bartow County College and Career Academy (BCCCA) addressed lighting uniformity issues in parking lots and driveways with a lighting retrofit from Acuity Brands, Inc. Twenty-eight American Electric Lighting™ Autobahn LED luminaires were mounted to existing 30-foot aluminum poles, replacing 1,000-watt metal halide fixtures.
A fundamental paradigm shift in lighting technologies toward more efficient lamps and bulbs will significantly reduce global electricity demand for general illumination in the next few years, according to IHS.
The energy usage of the installed base of lighting technologies for general illumination will fall to a projected 2.75 trillion kilowatt-hours (kWh) by 2020, down 24% from 3.61 trillion kWh in 2013. Overall, the installed base for general lighting-which covers homes, businesses and street lamps but not architectural or theatrical lighting-will account for 10.3% of the net electricity generated in 2020, down from 16.4% in 2013.
