WHAT IS LED ?
Light-emitting diodes (LED) are semiconductors. As electrons pass through this type of semiconductor, it turns into light. Compared to incandescent and CFL lamps, LED lights are more efficient at turning energy into light. Therefore, less of the energy radiates from the lamp as heat.
Compared to traditional incandescents, energy–efficient light lamps such as halogen incandescents, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) have the following advantages: Typically use about 25%-80% less energy than traditional incandescents, saving you money.
LED light lamps emit much less heat than a CFL or incandescent lamp. In many cases, you can actually feel the temperature difference just by being near the light.
While many LED lamps are now dimmable, not all of them are and not all of them dim in the same way. Since LEDs consume such a low wattage, many types of dimmers do not function with LED in the same way that they do with high wattage load incandescents. If you require dimmable LED, you must be specific.
