Undeniable Efficiency of LEDs

Peter McArdle


Efficiency is a business buzzword that might be overused, but that’s because everyone is talking about it, and business owners and managers are always looking for ways to improve efficiency. Why? Because it saves them money, and since nearly all businesses operate with their lights on, LED lights are one of the lowest hanging fruits in business efficiency. LED lights are the most significant development in today’s lighting market for many reasons. Not only do LEDs provide the most energy efficient lighting method, but they provide usage efficiency, more practicality, and can even be used to create UV light and kill harmful bacteria and pathogens, both in the air on surfaces.

Energy Efficiency

Common LEDs, most specifically ones that are rated by ENERGY STAR or the DLC use an average of 75% less energy and can last 25 times longer than incandescent, fluorescent, or HID lights. LEDs just simply require less wattage than the alternative lightbulb, naturally making them more long lasting and efficient. According to energy.gov, “By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today’s electricity prices.” That is a lot!

Usage Efficiency

The efficiency of LEDs goes beyond just their technical energy output, too. LEDs are more efficient than their counterparts also because of how they can be used. LEDs allow light to be pointed in a specific direction, all but eliminating the need for excess reflectors and light trapping devices. By eliminating externalities, all the light can be used for its real purpose rather than being lost in the reflector or the fixture. Finally, LEDs emit very little heat as compared to incandescent and CFL bulbs. When you feel heat from a fluorescent tube, what you are feeling is the inefficiency, since any energy that is creating heat, is not being used to power the light.
