Choose LED lighting
LEDs illuminate 10 times longer than CFLs and 100 times longer than incandescents. They are mercury-free, and are better at saving energy than the most efficient compact fluorescents.

Light stairways, hallways, and common areas with these stylish, but inconspicuous, steel-cased lights. They’re suitable for indoor and outdoor use, install easily, and each bulb lasts up to 60,000 hours.
Light up your kitchen using the ultimate in energy-efficient illumination options. These strips of LED lights are low-voltage and require next-to-no-maintenance since they rarely (if ever) require replacement (they last up to 60,000 hours!).
Light up your Christmas trees, garland, windows, and doors with festive colors that are easy on the pocketbook. These ones are round, but they also come in a variety of other shapes and a wide array of colors.
Cool-to-the-touch, these super efficient little bulbs last 100,000 hours and come in a variety of fun shapes and colors (as well as frosted white). Use them for parties and special occasions, or every day lighting.
This slim desk lamp uses high-powered LED bulbs to provide 120 degrees of illumination. The arm swings 190 degrees so it can provide up-lighting as well as down-lighting and has a dimmer so you can adjust the brightness.
The Sun Jar is the ultimate in eco-friendly nightlights. Inside an ordinary Mason jar hides a solar cell, a rechargeable battery, and three low-energy LED lamps. When placed in direct sunlight, the solar cell charges the battery so that when the sun goes down, the jar automatically lights up, emitting a candle-like glow.
This company is focused solely on LED lighting. They carry task lighting, LED strips, outdoor signs, and modules in a variety of colors and styles. Many also come with solar collectors to turn outdoor fixtures into energy-free illuminators.
Before you buy
LEDs are much more expensive than incandescents and even CFL bulbs. Some cost between $35 and $65 each. But don't let that deter you as they generally pay back relatively quickly. This calculator will give you an ideas as to how long it will take until you receive a payback on your investment.LED bulb savings calculator.
Choosing LED lights helps you go green because…
- They use a fraction of the energy incandescent bulbs use, and are even more energy efficient than CFL bulbs. Their use translates into fewer carbon emissions from power companies.
- They don’t generate heat like incandescent bulbs, so fans and air conditioners can be used less frequently or at lower levels.
- They last longer than incandescent and fluorescent bulbs, so there’s less need to replace bulbs, which decreases production and disposal considerations.
- Unlike incandescent and fluorescent bulbs, they contain no mercury.
- The low-voltage required means solar power can supply sufficient energy.
Though homes and businesses around the world are currently replacing their wasteful incandescent light bulbs with the longer lasting, more energy-efficient CFL bulbs, there is yet another technology coming that may revolutionize the lighting industry and the way we think about illumination. LEDs are semiconductors that when tapped with an electronic current, produce light. Each LED diode, at about one-fourth-inch in diameter are small in size, but can be grouped together for greater intensity and are better at focused, or single direction lighting.
The big draw for LED lighting, however, is their efficiency and energy-saving ability. Some current estimates have LED bulbs lasting 10 times longer than CFL bulbs and more than 100 times longer than typical incandescent bulbs, while using a fraction of the energy of incandescent bulbs. Additionally, LED light bulbs contain no mercury (present in other bulbs, such as CFLs), so don't pose the same risk of toxic exposure. And they're cool to the touch, which means they don't produce heat like incandescents. As a result, they don't increase indoor temperatures and therefore reduce cooling bills as well.
Currently, LEDs are in the efficiency range of fluorescent tubes, and researchers are under mandate from the US Department of Energy (DOE) to ultimately deliver LEDs with 150 lumens per watt throughout a projected lifetime of at least 70,000 hours. In comparison, incandescent bulbs are capable of 10-18 lumens/watt and last for about 1,000 hours, and CFL bulbs emit 35-60 lumens/watt and have a lifespan of 8,000-10,000 hours.
The benefits of research currently in progress may have a large impact on the lighting industry. According to one researcher, if 25 percent of the light bulbs in the US were converted to 150 lumens/watt LEDs it could save $115 billion in utility costs by 2025, alleviating the need to build 133 new coal-burning power stations and cutting carbon emissions by 258 million metric tons.
