Solatube International, Inc. has introduced its latest game-changer: A product that saves up to 94 percent on lighting energy use, called the Solatubesolar Smart LED System. It works by harnessing the sun’s (free) daylight during the day and transitioning to cost- and energy-efficient LED lighting at night. The Solatube Smart LED System harvests daylight during sunlight hours (using the traditional Solatube Daylighting System model) and, as light levels begin to dim, its “smart” sensors activate the LED lighting. Serving as an ideal security feature, the LED lighting prevents homes from going completely dark once the sun goes down. For more information, visit
