Some comparison between LED Bulb and Incandescent Bulb

LEDbulbs are the rising stars of the home lighting market. The Incandescent bulbs that people have been using for decades are finally falling out of favor with the public and governments for a variety of reasons, primarily energy efficiency. anty881209wong 131129

Lumens

The amount of light given off by a light bulb is measured in lumens, and LED light bulbs give off more lumens per watt than any traditional incandescent light. According to the Madison Wisconsin Gas and Electric Company, LED bulbs generate 20 to 60 lumens per watt, while incandescent bulbs only generate 10 to 17 lumens per watt.

Wattage

Because LED lights are far more efficient than incandescent lights, an LED bulb uses far less wattage than an incandescent bulb, all while generating the same number of lumens. A 3-watt LED bulb can generate the same amount of light as a 45-watt incandescent bulb.

Heat and Efficiency

Incandescent bulbs generate heat as well as light, which cut down on both their lifespan and efficiency. An LED bulb generates almost no heat, while generating plenty of light. They also last years longer than incandescent bulbs, cut down on replacement costs.

Energy efficiency is still the main selling point for LED bulbs, however, and this factor is well justified to be weighted thusly as the differences in energy consumption levels can be huge. For instance, an Incandescent bulb that uses 50 Watts of energy can be replaced by an LED bulb that produces the same amount of light for only 3 watts. In general LED bulbs tend to only use up one fifth of the energy than halogen bulbs do. This difference in efficiency comes about as a result of the way Incandescent bulbs work.
