Independence LED retrofitted the lighting at a Burger King in Carteret, NJ, and published a case study showing the business model of the retrofit.
Like many similar Burger Kings that are about 2,400 square feet in size, this location has 35 troffer fixtures that are 2’x4’ with four 32-watt fluorescent tubes, totaling 128 watts per fixture. At 8,760h/year the fixtures each used 1,121 kWh/year. With an electricity rate of $.083/kWh, the lighting cost was $93 per fixture per year and $3,257 for all 35 fixtures.
By reducing the fixture wattage from 128 to 44, using a 44-watt LED Retrofit Kit, the annual savings is 735 kWh and $61 per fixture. With 35 fixtures, the annual savings is $2,137. This franchise owner has 46 locations.
