What+is+a+LED?

LED stands for Light emitting diode

LED's started off as a low-intensity red light however now they are available for any visible, UV or IR wavelengths and can also be very bright

Uses: night lighting, art lighting, porch and outdoor lighting, mp3 players, DVD players computers and TV's. There are versions of LED bulbs that can be used in regular lamps and light fixtures although are very expensive

Each diode in an LED is only ¼ of an inch in diameter and only needs 1/10 of a watt of energy to produce light

LEDs decrease in light as they get older ; they usually will not burn out suddenly

LEDs give off much less heat than incandescent bulbs and they last longer, about 50,000 hours.

LEDs contain no mercury. 80% of the energy consumed by an LED goes to producing light, unlike an incandescent bulb where 80% of the energy consumed goes to produce heat. This means it is more efficient.

It can cost anywhere from $25 to $60 for a bulb that gives off the same amount of light as a regular 60 or 75 watt incandescent bulb
