Learn why it makes sense to say goodbye to fluorescent, halogen and other technologies.
LEDs have swept the conventional lighting marketplace for a variety of reasons, most notably their extended lifespans, reduced energy consumption and lower maintenance requirements. By 2030, the DOE estimates that LED lighting could save 190 terawatt hours of electricity per year, which equates to a whopping $15 billion. As the purchase price of lamps and fixtures continues to fall, more and more facility managers are looking to upgrade their lighting systems with LEDs, given their many benefits compared to traditional technologies. Following are eight advantages for all store decision makers to consider:
1 | Energy efficiency
LED lights use about 50 percent less electricity than traditional incandescent, fluorescent and halogen options, resulting in substantial energy cost savings, especially for spaces with lights that are on for extended periods. LEDs also aim light in a specific direction unlike conventional bulbs, which emit light—and heat—in all directions (because LEDs are mounted on a flat surface, they emit light hemispherically rather than spherically). This directional lighting capability reduces wasted light and energy.
2 | Extended life
Unlike incandescent lighting, LEDs don’t “burn out” or fail, they merely dim over time. Quality LEDs have an expected lifespan of 30,000–50,000 hours or even longer, depending on the quality of the lamp or fixture. A typical incandescent bulb lasts only about 1,000 hours; a comparable compact fluorescent lasts 8,000 to 10,000 hours. With a longer operational life, LEDs can reduce labor costs of replacing bulbs in commercial situations, achieving a lower maintenance lighting system.
3 | Cold temperature operation
LEDs love the cold unlike fluorescent lamps. At low temperatures, higher voltage is required to start fluorescent lamps, and luminous flux (the perceived power or intensity of light) is decreased. In contrast, LED performance increases as operating temperatures drop. This makes LEDs a natural fit for refrigerated display cases, freezers and cold storage spaces in addition to outdoor applications such as the parking lot, building perimeter and signage. DOE testing of an LED refrigerated case light measured 5 percent higher efficacy (the efficiency of a light source in lumens per-watt, like miles-per-gallon) at -5°C, compared to operation at 25°C.
4 | Durability
Without filaments or glass enclosures, LEDs are breakage resistant and largely immune to vibrations and other impacts. Traditional lighting is usually contained in a glass or quartz exterior, which can be susceptible to damage. LEDs, on the other hand, tend not to use any glass, instead they are mounted on a circuit board and connected with soldered leads that can be vulnerable to direct impact, but no more so than mobile phones and similar small electronic devices.
