LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities.
The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.
LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than incandescent light bulbs. An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.
• Despite being a little more expensive than other types, LED bulbs provide a quick return on investment because of the lower cost in electricity and the durability of the bulbs.
• LED lighting uses less electricity than other bulbs, even more eco-friendly ones such CFLs. For instance, the equivalent of a 60 watt incandescent bulb in LED terms is around 6 watts.
