LED can be used to build energy-efficient lighting products that save energy, help protect the environment, reduce maintenance costs and make people and things look much more attractive than traditional lighting. And they can last much longer than traditional lighting. A main challenge with LED lighting is that it costs more upfront, but really, it’s no different than requiring insulation in homes and buildings. It can pay for itself over time with energy savings and lower maintenance costs. Keep this in mind when you initially invest in LED lights. Besides, how do you define expensive? Is it purely the up-front cost of a light or do you factor in the cost of the energy to run that light and, if you’re a business or government, the cost to change the light bulb? And if you’re building a new building, installing LED lighting is often just about the same cost as traditional technology—and you’ll start saving money, through reduced energy consumption, the minute you flip the switch.
