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.

This allows them to produce the same amount of light, but use less energy.View the chart for key differences.alogen bulbs use a filament thatâs heated to the point of glowing, the same as incandescent bulbs, but they use less energy. 1  Halogen bulbs last on average 1 year. 2  Halogen bulbs do not contain mercury.
