LED bulbs are made from small electronic diodes that remain cool to the touch, whereas incandescent bulbs are made up of filaments (wires or threads) that get hot and eventually burn out. LED bulbs are six or seven times more efficient than incandescent bulbs, using 80% less energy, however, they don't fit all situations.

The main difference between LED and incandescent lights lies in their fundamental technology and energy efficiency. Incandescent lights use a filament that heats up to produce light, while LED lights operate by passing an electric current through a microchip, illuminating tiny sources called LEDs.

LED bulbs work differently than traditional ones. They produce light through electroluminescence, not incandescence like traditional bulbs. This means they use much less energy to produce the same amount of light, making them more efficient. In addition, LED bulbs last much longer than traditional ones.

LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions.

When you compare LED lights vs regular lights an LED literally outshines both incandescent and CFL bulbs for the same wattage. A 40W LED produces something like nine times as many lumens, the unit you measure light in, as a 40W incandescent bulb. The difference between LEDs and CFLs is not so marked, but the LED still comes out on top.
