Efficiency:? ? ?: LEDs emit more light per watt than incandescent light bulbs. The? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?efficiency of LED lighting fixtures is not affected by shape and size,? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?unlike fluorescent light bulbs or tubes.
Color? ? ? ? ? ? ? ?:LEDs can emit light of an intended color without using any color filters
Size? ? ? ? ? ? ? ? ? ?:LEDs can be very small (smaller than 2 mm) and are easily attached to? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? printed circuit boards.
On/Off time:?LEDs light up very quickly
Cycling? ? ? ? ? :?LEDs are ideal for uses subject to frequent on-off cycling,.
Dimming? ? ? : LEDs can very easily be dimmed either by pulse-width modulation or? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?lowering the forward current..

Cool light? ? ? ?: In contrast to most light sources, LEDs radiate very little heat in the? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?form of IR that can cause damage to sensitive objects or fabrics
Lifetime? ? ? ? ?:?LEDs can have a relatively long useful life.
Shock resistance: LEDs, being solid-state components, are difficult to damage with external shock.
