Why LED ?
LED lighting offers important energy savings to all types of establishments, including homes, businesses, retailers, industrial complexes, and municipalities.
You've probably noticed that "going green" is everywhere these days. You can hardly escape it in most choices your life. But, what's the real point of going green? Is it worth the trouble? We probably all have a general idea that going green helps the environment and saves resources and rainforests. But embracing a greener lifestyle isn't just about helping to preserve rain forests; it is also about improving your health, saving you money, and ultimately, improving your overall quality of life.
While it's easy to get overwhelmed with the stream of "go green" information everywhere, it's also easy to begin making a positive impact. As globalization decreases the size of the planet in terms of contact, communication, and interaction with people around the world, it becomes increasingly easy to see how the lives of people, animals, plants, and ecosystems everywhere are closely tied to one another. So, pesticides used in Bolivia can affect the health of people in the U.S., toys made in China can affect the quality of life in Europe and greenhouse gas emissions from Australia can affect a thinning rainforest in Brazil.
The truth is, everything we do, every day, good or bad, has an impact on the planet.
The good news is that you have the power to control most of your choices at the individual level and, therefore, the control the global impact you create.
The regular incandescent light bulb is a relic of the 19th century – a technological dinosaur. About the only thing it has going for it is that the price of the individual bulb is relatively low. CFLs (fluorescents) offer no versatility and contain harmful elements to the environment. With a little math and some foresight, you’ll soon realize that LED lights are much better options.
LED bulbs last for extended periods between replacements. These bulbs boast a lifespan of roughly 60,000 hours compared to the CFL’s 10,000 hours and the incandescent bulb’s 1,500 hours. It can withstand punishment from shock, heat, humidity, freezing temperatures and the constant on-off and dimming that is often the bane of incandescent and CFLs. Considering the LED bulb’s low energy usage, the cost over its lifespan is significantly lower than either of the other bulbs.
If using as little energy as possible with little or no replacements is your goal, then LED lights are for you.
Lighting consumes up to 34 percent of U.S. electricity. When electricity is produced by burning coal (as is half of the electricity in the United States), each kilowatt-hour releases over two pounds (nearly 1 kilo) of carbon dioxide (CO2). The buildup of CO2 and other “greenhouse gases” in the atmosphere is a major contributor to climate change and global warming, resulting in more frequent and severe storms and droughts, the rapid spread of infectious diseases, rising sea levels, and other adverse effects that could harm the human race and threaten other life on Earth.
burns up to 25% of the average home energy budget.
Light Emitting Diode (LED) bulbs have revolutionized energy-efficient lighting.
LEDs are solid state light bulbs which are
extremely energy-efficient. Until
recently, LEDs were limited to single-bulb use in applications such as cell
phones, calculators, instrument panels, electronics, pen lights and, more
recently, strings of indoor and outdoor Christmas lights. However, manufacturers have expanded the
application of LEDs by "clustering" the small bulbs. Today, LED bulbs are made using clusters, and
encased in diffuser lenses which spread the light in wider beams. Available with standard bases which fit common
household light fixtures, LEDs are the next generation in home and commercial
LEDs will soon become the standard for most lighting needs, leading the path to a sustainable future.
Benefits of LED light bulbs
Long-lasting - LED bulbs last up to 10 times as long as compact fluorescents, and up to 50-75 times far longer than typical incandescent bulbs.
Durable – LED bulbs do not have a filament, so they are not damaged under conditions where a regular incandescent bulb would be broken. Because they are solid, LED bulbs also hold up well to jarring and bumping.
Cool - LED bulbs do not cause heat build-up; LEDs produce 3.4 btu's/hour, compared to 85 for incandescent bulbs. This also cuts down on air conditioning costs in the home. Typical incandescent bulbs’ energy is disproportionately consumed in heat – 90% heat and 10% light. LED bulbs are the polar opposite with 10% heat and 90% light. Tests show 100W incandescent lights burning at 335.4 F, equivalent CFL lights burning at 179.2 F and LED bulbs burning at 87.2 F. LED lights are definitely the lowest risk to set off a fire. In fact, although not recommended, LED bulbs can be unscrewed while operating for hours and days. DO NOT TRY THIS WITH ANY OTHER TYPES OF LIGHT BULBS.
Eco-Friendly – LED bulbs contain no mercury or any other hazardous material. Fluorescent lights and CFLs (compact fluorescent lights) cannot be disposed of like the LED light because they contain mercury which seeps into the Earth's soil and water supply when improperly disposed. Many state’s laws prohibit disposal of mercury-containing bulbs in the trash and are punishable by steep fines. LED lights are safe to discard normally. Many materials in LED lights can actually be recycled. This, of course, is a not an issue since you will rarely throw away any LED light bulbs in your lifetime.
Energy-efficient - LED light bulbs produce as low as 8% watts of electricity as compared to incandescent or CFL, saving up to 92% on electrical usage. For example, a 3 watt LED light bulb can emit the same amount of light (in lumens) as a 45 watt incandescent bulb. Also, because these bulbs last for years, energy is saved in maintenance and replacement costs.
Cost-effective - the cost of LED bulbs is recouped over time in replacements costs and energy savings. Depending on your usage the costs can be recouped within an average of 1-3 years.Versatile – LED bulbs can be manufactured in all lighting temperatures (warm, soft, cool, etc.) and all angles ranging from spot to flood, allowing for the perfect ambiance and lighting experience to be achieved.
