LED Lights |Recent Residential Lighting Upgrade in Australia, Victoria LED stands for light emitting diode. LED products create light about 90% more efficiently than incandescent light bulbs. When an electric current passes through a microchip, it illuminates the tiny light sources called LEDs that emit light in the visible spectrum. LEDs have heat sink built-in that absorb radiated heat to keep energy consumption and dissipation of heat low. Lifespan of LED Lighting Products Lifespan of LED products is longer than incandescent or CFLs. They last over 50,000 hours or 20 years. Unlike traditional bulbs, LEDs don’t burn out or fail. Instead, they have lumen depreciation, which means the brightness of LED bulbs diminishes over time. How are LED Bulbs Different from Incandescent and CFL Bulbs? LED bulbs differ from incandescent and CFLs in several ways. They are more efficient, versatile, and durable. LEDs are directional light sources, i.e., they emit light in a specific direction, unlike incandescent and CFLs, which emit light and heat in all directions. This makes LEDs energy efficient. Needless to say, sophisticated engineering is required to make LED light bulbs that last longer and shine bright while consuming less energy. Lower energy consumption means lesser greenhouse gas emission. If ever wondered how a light bulb with sealed glass could produce any greenhouse gas, here’s some food for thought – it’s not the light bulb but carbon emission during the generation of electricity a light bulb consumes. Coal power stations being one of the biggest contributors of all. Three main pollutants a powers station produces are: Sulfur Dioxide: Responsible for acid rain
