We are often asked about all the different types of lighting currently available. As you know, incandescent light bulbs will not be around forever. 90% of their energy use is wasted by emitting heat instead of light. A light-emitting diode, or LED, is a type of solid-state lighting that uses a semiconductor to convert electricity into light. LED bulbs use only a fraction of the energy of an incandescent light bulb, so there is a dramatic decrease in energy costs. LEDs have a higher initial cost but they are far less expensive than they were a year ago and can provide huge long-term savings. Good quality LED bulbs can have a useful life of 25,000 hours or more – meaning they can last more than 25 times longer than traditional light bulbs. An LED bulb would last more than 3 years if run 24 hours a day, 7 days a week. Because LEDs are not made of glass and are hollow inside, they are far less fragile than both fluorescent and incandescent bulbs. LED lights are resistant to shock, vibration and external impact, making them great for outdoor lighting systems exposed to wind, rain and extreme temperatures.
