Fluorescent Efficiency

LEDs have several advantages over conventional incandescent lamps. For one thing, they don’t have a filament that will burn out, so they last much longer. Additionally, their small plastic bulb makes them a lot more durable. They also fit more easily into modern electronic circuits.

But the main advantage is efficiency. In conventional incandescent bulbs, the light-production process involves generating a lot of heat (the filament must be warmed). This is completely wasted energy, unless you’re using the lamp as a heater, because a huge portion of the available electricity isn’t going toward producing visible light. LEDs generate very little heat, relatively speaking. A much higher percentage of the electrical power is going directly to generating light, which cuts down on the electricity demands considerably.

Up until recently, LEDs were too expensive to use for most lighting applications because they’re built around advanced semiconductor material. The price of semiconductor devices has plummeted over the past decade, however, making LEDs a more cost-effective lighting option for a wide range of situations. While they may be more expensive than incandescent lights up front, their lower cost in the long run can make them a better buy. In the future, they will play an even bigger role in the world of technology.

The Specific Benefits of LED Light
Energy efficiency – The light bulbs burn very cool, while incandescent bulbs emit 98 percent of their energy as heat! Much more bang for the buck.

Long life – These lights can last from 50,000 to 100,000 hours. Incandescent light bulbs typically last around 1,000 hours and fluorescents are good for roughly 10,000 hours.

Rugged durability – LED lights have no fragile filament to contend with, and no fragile tube. They are resistant to heat, cold, and shock.

Lumens per watt – While manufacturers are still finding new ways to increase this ratio, Cree Inc. has been able to produce an LED bulb that generates 131 lumens/watt. This is research, though. Today’s available LEDs are the same as compact florescent bulbs, averaging around 55. Incandescent bulbs wander sadly in at about 15.
