LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.
LED lighting is available in a wide variety of home and industrial products, and the list is growing every year. The rapid development of LED technology has resulted in increased product availability, improved manufacturing efficiency, and lower prices. Below are some of the most common types of LED products.
The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting.
Because LEDs are small and directional, they are ideal for lighting tight spaces such as countertops for cooking and reading recipes. Since there can be variation in light color and directionality, it is important to compare products to find the best fixture for your space.
Recessed downlights are commonly used in residential kitchens, hallways, and bathrooms, and in a number of office and commercial settings. DOE estimates there are more than 600 million recessed downlights installed in U.S. homes and businesses.
With performance improvements and dropping prices, LED lamps can affordably and effectively replace 40, 60, 75, and even 100 Watt incandescent bulbs. It's important to read the Lighting Facts Label to make sure the product is the right brightness and color for its intended use and location.
LEDs consume far less electricity than incandescent bulbs, and decorative LED light strings such as Christmas tree lights are no different. Not only do LED holiday lights consume less electricity, they also have the following advantages:
When you switch to energy-efficient lighting, you can light your home using the same amount of light for less money. Lighting accounts for around 15% of an average home's electricity use, and the average household saves about $225 in energy costs per year by using LED lighting. if you are still using incandescent light bulbs, switching to energy-efficient lighting is one of the fastest ways to cut your energy bills. For high-quality products with the greatest energy savings, choose bulbs that have earned the ENERGY STAR.
In addition to efficient lighting, consider using controls such as timers and dimmers to save electricity. Timers automatically turn lights off when not in use by turning lights off when not in use, and dimmers can be used to lower light levels. Be sure to select products that are compatible with the energy-efficient bulbs you want to use.
If you have outdoor lighting that is left on for a long time, using LEDs or CFLs in these fixtures can save a lot of energy. LEDs and CFLs are available as flood lights, and have been tested to withstand the rain and snow so they can be used in exposed fixtures. For high quality products with the greatest savings, look for ENERGY STAR-qualified fixtures that are designed for outdoor use and come with features like automatic daylight shut-off and motion sensors.
Light emitting diodes (LEDs) are a type of solid-state lighting -- semiconductors that convert electricity into light. Although once known mainly for indicator and traffic lights, LEDs in white light, general illumination applications are today's most energy-efficient and rapidly-developing lighting technology. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs.
LED technology is available in many lighting product types including replacements for 40W, 60W, 75W, and 100W traditional incandescent bulbs, reflector bulbs used in recessed fixtures, and track lights, task lighting, undercabinet lighting, and outdoor area lights. LEDs come in a variety of colors, and some bulbs can be tuned to different colors or different hues of white light. Some are dimmable or offer convenient features such as daylight and motion sensors. LEDs work well indoors and outdoors because of their durability and performance in cold environments. Look for LED products such as pathway lights, step lights, and porch lights for outdoor use. You can also find solar-powered LED outdoor lighting.
The cost of LED light bulbs has decreased dramatically since they entered the market and prices are expected to come down further as more products become available. While LEDs are more expensive than traditional incandescent bulbs, they still save money because they last a long time and have very low energy use.

LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.
LEDs use heat sinks to absorb the heat produced by the LED and dissipate it into the surrounding environment. This keeps LEDs from overheating and burning out. Thermal management is generally the single most important factor in the successful performance of an LED over its lifetime. The higher the temperature at which the LEDs are operated, the more quickly the light will degrade, and the shorter the useful life will be.
LED products use a variety of unique heat sink designs and configurations to manage heat. Today, advancements in materials have allowed manufacturers to design LED bulbs that match the shapes and sizes of traditional incandescent bulbs. Regardless of the heat sink design, all LED products that have earned the ENERGY STAR have been tested to ensure that they properly manage the heat so that the light output is properly maintained through the end of its rated life.
In a CFL, an electric current flows between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb. Learn more about CFLs.
An incandescent 60-watt bulb, for example, gives off 800 lumens of light. And LED bulbs, which are more energy efficient than their incandescent counterparts, can deliver the same amount of light using as little as 10 watts.
When we asked for your questions about light bulbs, we got an earful. So we called in Noah Horowitz, director of the Natural Resources Defense Council's Center for Energy Efficiency, to answer your most frequently asked questions.
(We should note that Natural Resources Defense Council, a nonprofit environmental organization, is a strong backer of energy-efficient lighting. It receives a small percentage of funding from government grants, including one from the EPA Energy Star program to accelerate the adoption of energy-efficient equipment.)
As not all CFLs are created equal, only buy those that have the Energy Star logo on them. Those bulbs are not only efficient but also meet the Environmental Protection Agency's rigorous performance requirements and must pass various tests including longevity. Switching your CFL on and off frequently may shorten its life. Additionally, CFLs may not turn on or reach their full brightness in really cold temperatures.
CFLs have very low levels of mercury in them, now as low as 2 mg per bulb. Consumers should take advantage of free CFL recycling programs that are offered by leading retailers such as Home Depot and Lowe's. You should also be aware that while incandescent bulbs do not contain mercury, they cause a lot more mercury to be emitted into the environment from coal-burning power plants, since they use four times more energy than a CFL to produce the same amount of light.
If you want to have different levels of light and use an energy-saving bulb, you have two great choices. If you have a three-way socket, you can buy a three-way CFL which will offer low, medium and high light output, just like your old incandescent bulb did. If your fixture is dimmable, almost all LEDs are dimmable and you can enjoy even more flexibility.
The great news is there is an energy-efficient CFL or LED for just about every socket. These include candelabra or flame-shaped bulbs, as well as the round globe-shaped bulbs that are often used in the bathroom vanity over the sink. Candelabra and globe CFLs have been around for years, and LED models are coming on line now, too.
Fixtures have a safety rating and one should not put in bulbs that exceed the labeled rating (such as \"do not exceed 60 watts\"). As long as you don't put a bulb that uses more than 60 watts in that socket you will be fine.
The good news is the energy-saving bulbs that replace a 60-watt incandescent will only use 10 to 15 watts, depending on the actual bulb you buy, and give off the same amount of light. If you want even more light, you can bump up to a 23-watt CFL that will give off as much light as the old 100-watt bulb did, while still staying below the 60-watt power cutoff. You should not, however, install a 100-watt bulb, as that could cause a fire hazard.
CFLs do not work well in cold climates and may not even start, so are not a good choice for the porch light or other outdoor sockets in cold climat
