LEDs are incredibly efficient light sources. An LED is a tiny semiconductor that transforms the energy from individual electrons into photons of light.
In contrast, incandescent light bulbs work by heating a tiny metal filament until it glows. Most of the energy is lost as heat instead of light. This is a huge waste of energy.
