LEDs have several benefits beyond just energy efficiency. Indeed, we’ve come a long way since Edison’s first commercially produced light bulb, back in 1880, using a carbonized bamboo filament. An LED (Light Emitting Diode), is six to seven times more energy efficient and cuts energy usage up to 80%. But beyond the energy savings, there are even greater benefits to LED use as technology advances.
8 Advantages of LED Lighting
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.
2. Extended life
Unlike typical 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.
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.
5. Instant on
Most fluorescent and HID lamps do not provide full brightness the moment they’re switched on, with many requiring three minutes or more to reach the maximum light output. LEDs come on at 100-percent brightness almost instantly, however, with no re-strike delay. This can be advantageous following a power outage or anytime employees open a building during early morning hours when it is still dark outside.
6. Rapid cycling
Traditional light sources tend to have a shorter lifespan the more they’re switched on and off, whereas LEDs are unaffected by rapid cycling. In addition to flashing light displays, this capability makes LEDs well suited for use with occupancy or daylight sensors.
It can take more than a few dollars to make commercial fluorescent lighting systems dimmable, but LEDs, as semiconductor devices, are inherently compatible with controls. Some LEDs can even be dimmed to 10 percent of light output while most fluorescent lights only reach about 30 percent of full brightness.
8. No IR or UV Emissions
Less than 10 percent of the power used by incandescent lamps is actually converted to visible light; the majority of the power is converted into infrared (IR) or radiated heat. Excessive heat and ultraviolet radiation (UV) presents a burn hazard to people and materials. LEDs emit virtually no IR or UV.
