LED lights are commonly discussed in the news today, for a variety of different reasons. Above all, there’s a great deal of emphasis on the fact that they’re considered “energy efficient”. But what does this mean exactly, and is it really the case? For a better understanding of this important topic, here are the top 4 reasons why LED lights are energy efficient, making them the best choice for residential, commercial and industrial applications. Lots of Light and Little Heat LEDs use only a fraction of the energy used by CFLs or incandescents to produce the same amount of light. For example, the standard 40 watt incandescent bulb produces 400 to 500 lumens (a measurement of light brightness). To produce this light with CFLs, you would need to use 8 to 12 watts. LEDs are simply more efficient; Flexfire LEDs’ UltraBright strip lights, for example, each foot of reel produces 400 to 670 lumens for just 4.4 to 7.5 watts. The reason for this is that the vast majority of energy that goes into LED lights is transferred into light. When properly engineered, many LED lights operate near 80% efficiency. That means 80% of the energy used becomes light. Incandescent bulbs on the other hand, work at just 20% efficiency, meaning that 80% of the energy used is transferred into heat—instead of light. The U.S. Energy Information Administration estimates that 17% of the total energy used by the United States’ commercial and residential sectors in 2012 went to lighting. That means switching to more efficient LEDs could have a dramatic impact on the country’s energy consumption. Longer Lasting When a light bulb goes dead, it costs energy to replace it. First, a factory must use energy to build its replacement. Then more energy is used...
