Parking garages often operate 24/7, which can lead to significant maintenance expenses with traditional light sources such as probe start metal halide as well as high energy costs. LED fixtures often offer a 70 percent reduction in energy consumption and will be virtually maintenance-free for decades. From a safety standpoint, LED luminaires are instant on/off and offer superior visual uniformity to enhance the level of safety. In addition, LED luminaires are available with integral control options that further reduce operating costs while also enhancing safety. Because of the long life LEDs offer, often 50,000–100,000 hours—at least several times greater than HID and fluorescent counterparts—as well as their robust operability and efficiency gains in cold temperatures, maintenance savings are a major plus because customers aren’t having to re-lamp over and over again during the life of the fixture.
