Lighting comes in various shapes, sizes, colors, and most importantly: technology. These four factors affect energy consumption, brightness, and more. The most-up-to-date technology available in the market today are LED (light emitting diode) lights. LED lights are 85% more energy efficient than traditional incandescent lights. LED lights also last 25x longer. Other energy efficient lights that are common but older in technology compared LEDs are called CFLs (compact fluorescent lighting). CFLs are still more efficient than traditional incandescent lights and have already been popularized by older rebate and incentive programs.
LED technology has been around for 50 years but only recently has been popularized for it's energy saving abilities and modern design. The high cost associated with LEDs have been a major deterrent for the general public in upgrading to them. Fortunately, this problem has been identified by local utilities and rebates are being promoted to help off-set the costs associated with the LED upgrades.
