The main difference from other light sources is the directed light. LED lamps are used for both general and special-purpose lighting. Where colored light is needed, LEDs that inherently emit single colored light require no energy-absorbing filters.

White-light light-emitting diode lamps have longer life expectancy and higher output (the same light with less electricity) than most other lighting. LED sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses. Because of the small size of LEDs, control of the spatial distribution of illumination is extremely flexible,[2] and the light output and spatial distribution of a LED array can be controlled with no efficiency loss.
LEDs using the color-mixing principle can emit a wide range of colors by changing the proportions of light generated in each primary color. This allows full color mixing in lamps with LEDs of different colors.[3] In contrast to other lighting technologies, LED emission tends to be directional (or at least lambertian). This can be either an advantage or a disadvantage, depending on requirements. For applications where non-directional light is required, either a diffuser is used, or multiple individual LED emitters are used to emit in different directions
