Benefits of LED

Cool operating
LEDs produce very little heat. They are more efficient and cause less damaged when being used to illuminate such items as clothing, food, painting etc because less IR and UV is produced.
Colour rendering
LEDs can produce any colour within the spectrum RGB colour mixing. Colouring the light output of incandescent lamps requires either colour diachroic glass or theatrical colour filters.
One of the main benefits of LED is energy saving because they operate at 75% efficiency.
LEDs can be dimmed easily.
LEDs produce more light per watt than incandescent lamps making them 75% more efficient compared that to the 6% efficiency of a standard incandescent.
LEDs are mercury and lead free, which assists greatly towards the environment.
LEDs. 25,000 through to 50,000 hours.
CFL lamps. (Compact fluorescent light bulbs) 6,000 – 15,000 hours
Fluorescent tubes. 10,000 to 15,000 hours
Incandescent lamps. 1,000 to 3,000 hours
Response time
LEDs are more efficient at responding to being switched on and off at regular intervals.
LEDs operate at low temperatures and require very little current which in turn produces less heat and less energy. LEDs are subject to very limited wear.
LEDs are often smaller than incandescent lamps depending on their output.
Slow failure
LEDs tend to slowly change their colour temperature output when coming to their end of their life rather than burning out.
