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.
Newer bulbs are more efficient and make the traditional 100-watt incandescent bulb obsolete. Around 90% of the electricity used by traditional incandescent bulbs is wasted as heat instead of visible, usable light. More efficient bulbs produce the same amount of light but waste less energy in the form of heat.
