LEDs are not frequently seen in many houses, there are reasons to want them there in greater numbers. First, they reduce the energy consumed. LED method of producing light loses far less energy to heat than do other lighting technologies. It is more efficient than the vacuum/filament method used in incandescent bulbs -- sometimes around 85 percent more efficient; and it's even about 5 percent more efficient than the CFL's plasma-tube. A single light fixture stocked with a 60-watt incandescent bulb consumes about 525 kWh(Unit) of electricity in a year; put a LED bulb in that light fixture, and the annual energy use is more like 65 kWh (Unit) Solid-state lights like LEDs are more stable light sources than incandescent or fluorescent bulbs, and the difference is startling: A typical incandescent bulb lasts about 750 hours; LED Bulb lasts 50,000 hours. The other primary LED issue -- degradation in the colour of the light to something bluish -- has been solved in newer models. LEDs can produce the same soft, white light as a regular bulb. Price is the only problem with LED light bulbs right now.
