LEDs are âdirectionalâ light sources, which means they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs, which emit light and heat in all directions. For this reason, LED lighting is able to use light and energy more efficiently in many applications.
Lastly, the type of light bulbs that are installed has a significant effect on energy consumption. The efficiency of light sources vary greatly. Fluorescent lights produce several times as much light, for given power input, as incandescent lights do, and LEDs are continuing to improve beyond that.
