LEDs utilize half as much energy as typical incandescent, fluorescent, and halogen bulbs, resulting in significant energy savings, particularly in areas where lights are left on for long periods, in contrast to traditional bulbs, which release light and heat in all directions, LEDs direct light in a specific direction. The ability to produce light saves both light and energy.
LEDs, unlike incandescent lighting, do not “burn out” or “fail”; instead, they dim over time. Depending on the quality of the bulb or fixture, LEDs have a lifespan of 30,000–50,000 hours or even more. An incandescent bulb lasts roughly 1,000 hours, while a compact fluorescent bulb lasts 8,000 to 10,000 hours. LEDs can reduce labor expenses associated with bulb replacement in commercial settings, resulting in a lower-maintenance lighting system.
Unlike fluorescent lights, LEDs enjoy the cold. Fluorescent lamps require more voltage to start at low temperatures, and their luminous flux (the apparent power or intensity of light) is reduced. In contrast, as working temperatures drop, LED performance improves. LEDs are therefore ideal for refrigerated showcases, freezers, and cold storage areas, as well as exterior applications such as parking lots, building perimeters, and signage.
Most fluorescent and HID bulbs don’t turn on to full brightness immediately, and many take three or longer to attain full brightness. On the other hand, LEDs turn on at full brightness practically quickly and do not require re-striking. This is useful during a power loss or if personnel enter a business early in the morning while it is still dark outside.
