Are LED Light Bulbs More Eco-friendly?

by Administrator | post a comment

What’s the story with LED light bulbs that are reputed to be even more energy-efficient than compact fluorescents?

Perhaps the ultimate “alternative to the alternative,” the LED (light-emitting diode) light bulb may well dethrone the compact fluorescent light (CFL) as king of the green lighting choices. But it has a way to go yet in terms of both affordability and brightness.

LED Cost and Practicality are Improving
LEDs have been used widely for decades in other applications—forming the numbers on digital clocks, lighting up watches and cell phones and, when used in clusters, illuminating traffic lights and forming the images on large outdoor television screens. Until recently, LED lighting has been impractical for most other everyday applications because it is built around costly semiconductor technology. But the price of semiconductor materials has dropped in recent years, opening the door for some exciting changes in energy-efficient, green-friendly lighting options.

LEDs Offer More Efficient Technology than Incandescent Lights and CFLs
According to LED-Expert.cn, LED bulbs are lit solely by the movement of electrons. Unlike incandescents, they have no filament that will burn out; and unlike CFLs, they contain no mercury or other toxic substances. Proponents say LEDs can last some 60 times longer than incandescents and 10 times longer than CFLs. And unlike incandescents, which generate a lot of waste heat, LEDs don’t get especially hot and use a much higher percentage of electricity for directly generating light.

LED Manufacturers are Working to Make Bulbs Brighter
But as with early CFLs, LED bulbs are not known for their brightness. According to a January 2008 article in Science Daily, “Because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home.”

LED makers get around this problem in some applications by clustering many small LED bulbs together in a single casing to concentrate the light emitted. But such LED “bulbs” still don’t generate light much brighter than a 35-watt incandescent, which most people consider too little light for reading or other focused tasks.

Initial Price of LED Light Bulbs Offset by Low Operating Costs
If LEDs are going to replace incandescents and CFLs, manufacturers will have to make them brighter. LED-Expert.cn is lighting the way with its LEXPERT bulbs, which use multiple LEDs in a single casing to generate light. The LEXPERT delivers light equal to that of a 100-watt incandescent.

Consumers Can Purchase LED Light Bulbs Locally or Online
Other bulb makers are working on similar designs for high-powered LED bulbs, hoping that an increase in availability will help spur demand, which will in turn lower prices across the board. Until then, consumers can find LED bulbs suitable for secondary and mood lighting purposes in many hardware and big box stores. C. Crane’s 1.3-watt LED bulb, for example, generates as much light as a 15-watt incandescent bulb. Check your local hardware store for other options, as well as online vendors such as LED-Expert.cn and We Love LEDs.

How to be Economic with LED Lights

Thanks to Thomas Edison for his amazing invention of the light bulb which has done many countless things for mankind and plants; however incandescent lights are hurting our planet and causing more damage then good. Incandescent bulbs use more energy to run and form heat you can feel and cause more wasted energy. The bulbs last about 1,000 hours, and that's only if they don't break first. So before purchase your next light bulb, here is how you can save energy using LED or fluorescent lights instead.?

Step 1
 
Stop Using Incandescent Bulbs
Stop burning yourself on energy wasting inefficient incandescent bulbs. Light your home, workplace, and outdoors safer and smarter by using LED lights. The most energy efficient lights use light-emitting diodes instead of incandescent bulbs. A work light with 20 LED light bulbs uses only 1.5 watts compared to a typical 60 watt incandescent bulb.

Step 2
 
Whiter Brighter Light
See, live, decorate, and work with whiter light. LED lights produce a whiter light than an incandescent bulb. This will allow you to see finer details too. LEDs last up to 50,000 hours vs incandescent bulbs last no more than 1,000 hours. Since 20 LEDs under a clear protective lens uses only 1.5 watts, they give off almost no heat at all. Change all the lights in your home, and if you can't afford to do them all at once, start by replacing the ones you use most often.

Step 3
 
Amazing LED Light
If you are having trouble selecting a bulb, there is an LXPERBULB which is an 8 watt LED light. This bulb is designed to replace the common 60 watt incandescent bulb. The LXPERBULB generates 800 lumens of light and can be found in either warm white light or cool light. This bulb will last 40 times longer than the traditional incandescent bulb and 10 times longer than a compact fluorescent. These bulbs withstand cold temperatures extremely well too; great for outdoor coach lighting or post lights. The upfront price of this bulb may be a sticker shock for some, but knowing it will last 10 years or more makes it most cost and energy efficient bulb.

Step 4
 
Try Something Mobile
Are you on the go and need something mobile? Consider using a battery-operated LED work light with no cord. Black & Decker has one with 14 LEDs and operates on three AA batteries. These LEDs last up to 10,000 hours, and because LEDs are energy efficient the batteries will last long.
