Case study · Parking garage
394 garage lights, one switch
A Charlotte-area parking garage swapped 394 175W metal halide fixtures for 46W LED canopy fixtures, with a $100 Duke Smart Saver rebate on each and a 2-year return.
The job
The owner asked us for a garage lighting fix that would save energy and cut maintenance. They chose an LED fixture with a long life, a traditional look and a brighter, whiter color than the yellow of the old metal halides.
The garage had 394 fixtures with 175W metal halide lamps. We replaced all 394 with 46W LED canopy-style fixtures, which saved 156 watts per fixture.
Through the Duke Energy Smart $aver program, the garage qualified for a $100 rebate on every fixture. The project paid for itself in about 2 years.
