This interesting article highlights the benefits of changing to LED lighting, from reduced running costs, to maintenance and replacements.
It is no surprise that commercial/industrial applications are leading the transition to LEDs as lighting generally represents anywhere from 25%-40% of total energy use in commercial buildings. As these applications require long hours of high intensity light, the economic payback of the saved electrical power is relatively short-term. Secondly, the long life of LED fixtures dramatically reduces the replacement cost of the bulbs. These replacement costs not only include the price of the bulb itself, but also the labor cost to physically replace them, which in certain applications, such as high bay lighting, is significant. The primary driver behind the high growth rate of LED lighting is the reduction in power consumption that LED lighting offers over traditional lighting. Compared to incandescent lighting, LEDs require less than 20% of the electrical power to provide the same level of light.
