LED lighting is more efficient, durable, versatile, and longer-lasting than incandescent and fluorescents lighting. LEDs emit light in a specific direction, whereas an incandescent or fluorescent bulb emits light—and heat—in all directions. LED lighting uses both light and energy more efficiently.
For example, an incandescent or compact fluorescent (CFL) bulb inside of a recessed can will waste about half of the light that it produces, while a recessed downlight with LEDs only produces light where it’s needed—in the room below.
