The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.

Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting.

CFLs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks similar to the common incandescent bulbs- not like the fluorescent lighting we associate with factories and schools.

LEDs are small, very efficient solid bulbs. New LED bulbs are grouped in clusters with diffuser lenses, which have broadened the applications for LED use in the home. LED technology is advancing rapidly, with many new bulb styles available. Initially more expensive than CFLs, LEDs now bring more value since they last longer.

The Status of Energy Efficient Lighting

With a burgeoning supply of far more efficient light bulb options, the EU began a phased ban of incandescents in 2009. Canada followed suit banning the manufacture and import of higher wattage incandescent bulbs beginning in 2014.

In 2007, the U.S. set new energy efficiency guidelines for all bulbs, which effectively phased out the least efficient incandescent bulbs. Incandescents are now available only if they meet the new energy standard.

According to the US Department of energy, rapid adoption of LED bulbs would save hundreds of millions of tons of greenhouse gases from entering the atmosphere.

Australia, China, and numerous countries in Asia and Latin America have likewise phased out or banned incandescent bulbs. These changes are estimated to save each country that switches to energy efficient bulbs millions of dollars annually.

According to the US Department of energy, rapid adoption of LED bulbs would collectively save $265 billion over the next 20 years. This switch would also help eliminate the need to build 40 new power plants and save hundreds of millions of tons of greenhouse gases from entering the atmosphere.

LED Light Bulbs

LEDs (Light Emitting Diodes) are solid light bulbs that are extremely energy-efficient. When first developed, LEDs were limited to single-bulb use in applications such as instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor Christmas lights.

Manufacturers have expanded the application of LEDs by "clustering" the small bulbs. The first clustered bulbs were used for battery-powered items such as flashlights and headlamps. Today, LED bulbs are made using as many as 180 bulbs per cluster, and encased in diffuser lenses, which spread the light in wider beams. Now available with standard bases that fit common household light fixtures, LEDs are the next generation in home lighting.

A significant feature of LEDs is that the light is directional, as opposed to incandescent bulbs, which spread the light more spherically. This is an advantage with recessed lighting or under-cabinet lighting, but it is a disadvantage for table lamps. New LED bulb designs address this directional limitation by using diffuser lenses and reflectors to disperse the light more like an incandescent bulb.

The high cost of producing LEDs has been a roadblock to widespread use. However, researchers at Purdue University have developed a process for using inexpensive silicon wafers to replace the expensive sapphire-based technology. This has rapidly brought LEDs into competitive pricing with CFLs and incandescent bulbs. LED bulbs are now the standard for most lighting needs.

Benefits of LED Lightbulbs

Long-Lasting

LED bulbs last up to 10 times longer than compact fluorescents, and 40 times longer than typical incandescent bulbs.

Durable

Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold up well to jarring and bumping.

Choosing an LED Light Bulb

Many different models and styles of LED bulbs are emerging in today's marketplace. When choosing a bulb, keep in mind the following:

Look for Certifications:

Common Styles of LED Bulbs

Diffused or Omnidirectional Bulbs

In this style LED bulb, clusters of LEDs are covered by a dimpled lens which spreads the light out over a wider area. Available in standard Edison bases, these bulbs have many uses, such as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.

Dimmable Globe LED Bulbs

Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.

LED Terminology

Coloring Rendering Index (CRI)

CRI represents the quality of light and its faithfulness to render colors correctly, that is, to enable us to perceive colors as we know them. The ideal CRI is 100, and some incandescent bulbs approach this level. LEDs and CFLs use different design components in trying to equal the CRI of incandescent bulbs. LED bulbs CRI ratings range from 70 to 95, and the best CFLs have ratings in the mid 80s. The LED CREE CR6 bulb, for example, features a CRI of 90 Warm White making it one of the highest in the industry.

Correlated Color Temperature (CCT)

CCT is the measure used to describe the relative color appearance of a white light source. CCT indicates whether a light source appears more yellow/gold/orange or more blue, in terms of the range of available shades of "white." CCT is given in kelvins (unit of absolute temperature). 2700K is "warm" and 5000K is "cool." The typical light color we are used to in indoor home lighting is "warm," 2700 - 2800K.

When buying a light bulb, look for bulbs that produce more light but consume less energy.

Lumen

A unit of standard measurement that is used to describe the amount of light contained in an area as perceived by the human eye. The more lumens, the brighter the light. You can use lumens to compare the brightness of any bulb, regardless of the technology behind it, and regardless of whether it's incandescent, CFL or LED.

Luminous Flux

The flow of light measured in lumens. With light bulbs, it provides an estimate of the apparent amount of light the bulb will produce. Depending on the application, much of an incandescent bulb's light is wasted because it's emitted in every direction. LED bulbs, on the other hand, put out directional light, sending all of the light exactly where it's needed.

In practical application, when buying a light bulb, look for bulbs that produce more light but consume less energy. Understanding lumens as a measure of brightness makes it easier to select the most efficient bulb for your application.

LED Bulb Colors

Most LED bulbs used today are clear or white bulbs, commonly available in 'cool' or 'warm' white light. But LEDs are also available in colors and used as individual bulbs, or in clusters, for special applications.

Red

Red is the traditional color for maintaining night vision. Some LED headlamps and flashlights have the option of switching to red light for use at night.

Green

Green is now the preferred light color for pilots and the military. The green color is also great for retaining night vision, and it doesn't erase or render invisible the red markings on maps and charts.

Blue

Many people like blue light because it feels easy on the eyes, but research indicates that some lights in the blue spectrum can affect human circadian rhythms and therefore, sleep. Scientists now recommend against using objects lit with blue light 2-3 hours before bedtime.

White

The most popular of the LED colors. It produces a soft white light, without harsh reflection, glare or shadows.

Amber

LED amber bulbs do not attract flying insects like ordinary white bulbs. Amber LEDs are used outdoors in areas such as patios and decks where insects flying around lights are a nuisance.

Lumen Output Comparison: LED vs CFL vs Incandescent
Did you know that watts don't tell you how bright a light will be?
To compare different light bulbs, you need to know about lumens. Lumens, not watts, tell you how bright a light bulb is, no matter the type of bulb. The more lumens, the brighter the light. Beginning in 2012, labels on the front of light bulb packages now state a bulb's brightness in lumens, instead of the bulb's energy usage in watts.

While lumens are the best measurement of comparative lighting among the various bulbs, they are not always a perfect measure. Some floodlights use an internal reflector in the bulb to send the light facing downward. When shopping for light bulbs, note that bulbs equipped with reflectors will deliver increased directional light.

The chart below shows the amount of brightness in lumens you can expect from different wattage light bulbs. The LED bulbs require much less wattage than the CFL or Incandescent light bulbs, which is why LED bulbs are more energy-efficient and long lasting than the other types of bulb.

Handling and Disposal of LED Bulbs

LEDs can contain small amounts of heavy metals like lead, arsenic, and nickel, so it's best to handle with care. Treat any broken bulb as hazardous waste, which means wearing gloves and a mask and cleaning the area thoroughly. Double bag the bulb fragments and any cleaning tools used and contact your local hazardous waste site for instructions on their preferred method of disposal. Many will likely have you simply throw it in the trash, while others will ask that you bring it to the hazardous waste collection site.

While LEDs are recyclable, recycling programs are few and far between. Call your local recycling collection center to find out if LED bulb recycling is available in your area. You can also try searching at Recycle Nation for a recycling facility that accepts LED bulbs near you.

CFL Lighting Benefits

Efficient

CFLs are four times more efficient and last up to 10 times longer than incandescents. A 22 watt CFL has about the same light output as a 100 watt incandescent. CFLs use 50 - 80% less energy than incandescents.

Choosing a CFL

CFLs come in many shapes and sizes. When purchasing CFLs, consult the seller for recommendations and consider the following:

Choose Your Preferred Light Quality

CFL bulbs have a Kelvin or 'K' number listed on the packaging. CFLs with K numbers between 2700-3000 give off a soft bright light like incandescents. CFLs with K numbers between 3500-6000 give off a bright light. As you go up the K number scale the light gets bluish and closer to daylight.

For example:
Approx. 2700K = Warm White (looks just like incandescent)
Approx. 5000K = Cool White (white/blue, bright light)

Choose the Shape

CFLs are available in a variety of shapes to fit a range of lamps and lighting fixtures. See below on this page for the most popular CFL shapes.

Match Lumens to the Incandescent Being Replaced

Lumens indicate the amount of light being generated. (Wattage is a measure of energy use, not light strength.) Lumen output is printed on the bulb package or on the bulb product page if purchasing bulbs online.

CFL Light Bulb Models

CFLs are available in a variety of styles or shapes. Some have two, four, or six tubes. Older models, and specialty models, have separate tubes and ballasts. Some CFLs have the tubes and ballast permanently connected. This allows you to change the tubes without changing the ballast. Others have circular or spiral-shaped tubes. In general, the size or total surface area of the tube determines how much light the bulb produces.

The following CFL bulb models come with standard sockets for easy installation in most common household applications.

Limitations of CFL Lightbulbs

Although CFLs are an excellent source of energy-efficient lighting, they are not always the best choice for all lighting applications. Here are a few limitations to consider:

The principal reason for reduced lifespan of CFLs is heat. CFLs exhibit shorter lifespans in light fixtures and sockets where there is low airflow and high heat build-up such as recessed lighting. For these types of sockets it's recommended to use specially designed CFLs for recessed lighting or LEDs. Another main reason for reduced lifespan of CFLs is too-frequent on/off cycling. These bulbs should be used where they will be left on for steady periods without being flicked on and off.

Mercury and CFLs

Mercury is a toxic metal associated with contamination of water, fish, and food supplies, and can lead to adverse health effects. A CFL bulb generally contains an average of 5 mg of mercury (about one-fifth of that found in the average watch battery, and less than 1/100th of the mercury found in an amalgam dental filling). A power plant will emit 10mg of mercury to produce the electricity to run an incandescent bulb compared to only 2.4mg of mercury to run a CFL for the same time. The net benefit of using the more energy efficient lamp is positive, and this is especially true if the mercury in the fluorescent lamp is kept out of the waste stream when the lamp expires.

Handling and Disposal of CFLs

The mercury in compact fluorescent bulbs poses no threat while in the bulb, but if you break one:

Open a window and leave the room for 15 minutes or more.

Use a wet rag to clean it up and put all of the pieces, and the rag, into a plastic bag.

Place all materials in a second sealed plastic bag.

Call your local recycling center to see if they accept this material. If not, and you're located in the U.S., review the list of companies accepting CFL's by mail maintained by the Environmental Protection Agency.

Burned out CFLs can be dropped off at Home Depot and Ikea stores.

Another solution is to save spent CFLs for a community household hazardous waste collection, which would then send the bulbs to facilities capable of treating, recovering or recycling them.

For more information on CFL disposal or recycling, you can contact your local municipality.

Why Eartheasy Recommends LED Bulbs:

We have discontinued sales of CFL bulbs because we are concerned about the inconsistent quality standards among overseas manufacturers of CFL bulbs, and the use of mercury in these bulbs.

The rapid development of LED bulb technology has brought newer LED bulbs to the marketplace which are safer, longer lasting, and more energy efficient than today's CFL bulbs. The price of LED bulbs now delivers the best cost-savings over the life of the bulb when compared to CFLs or any other light bulb available today.

From Darren,
From this activity, I had learned that everything has a downside and an upside. No matter what it is, everything has a purpose as it was build to do something. But as technology rises, these things often get replace by new inventions which prove to do the things that they had done better. Even though as said, they can't directly replace old technology as everything has an advantage over the other, it's just how much advantage does it have over another. In this activity i had learned that although incandescent light bulbs are being replaced by energy saving ones, incandescent light bulbs still have their advantages such as radiating lots of heat which could be useful during very cold nights.Besides that, i had learned that we have be considerate and realize that what we do will affect other people for the good or even for the bad.
The link below shows the advantages and disadvantages of CFL light bulbs and LED light bulbs. Hope this link will help everyone in understanding the advantages and disadvantages of these bulbs.

# data[].attributes.attachment_link.readable_text
As technology progresses many of the things that were once commonplace become obsolete. Practically everything will eventually meet this fate; typewriters, cassette players, VCRs and public pay phones are all examples. The same is true for the incandescent light bulbs.

The world has two leading technologies positioned to take the place of the incandescent bulb; they are the light emitting diode (LEDs) and the compact fluorescent lamp (CFLs). In this article, our goal is to explain these emerging technologies so that you can make a better decision when choosing between the two.

The incandescent light bulb is becoming obsolete because it is extremely inefficient, especially when compared to a light emitting diode or a CFL bulb. Incandescent bulbs are very simple devices. Each one contains a filament, which allows electricity to pass through. This process converts electricity into heat, which causes the light bulb filament to glow white-hot creating light.

Most of the electricity that is used to light up incandescent bulbs is wasted on the heat that it produces. As a result, many countries around the world have implemented some type of incandescent light bulb ban, which bars retailers from selling them. This has influenced both businesses and homeowners to choose from alternative light sources when living life in the green zone.

CFLs - Compact Fluorescent Bulbs

As the name implies a compact fluorescent bulb is just a miniature version of a fluorescent light. Due to the fall of incandescent light bulbs, these fluorescent fixtures are now being used in many homes and business across the globe.

A CFL bulb works by driving electrical current through a tube containing mercury vapor and argon. This produces invisible ultraviolet light, which excites the phosphor coating of the lamp. Phosphor is a synthetic material that emits visible light when it is exposed to ultraviolet radiation.

Because of their design, CFL light bulbs use one-fifth to one-third of the electricity it takes to generate the same amount of light use a comparable incandescent bulb. They also last eight to fifteen times longer, averaging about 12,000 hours per bulb making them much more energy efficient. That is why so many manufactures advertise these fixtures as energy-saving light bulbs.

Despite the fact that this type of light bulb has been around since the early 20 th century, it took nearly 100 years for manufactures to develop the spiral shaped bulb that is popular today. Since the first helical CFL bulbs became commercially available in 1995 their popularity has steadily increased year after year. However, like most things in the world, CFL light bulbs come with advantages and disadvantages. We will take the time to discus some here.

Advantages of CFL Light Bulbs

According to the US Department of Energy, CFL light bulbs on average use 75% less electricity and last ten times longer than the average incandescent bulb.

Since the 1990's bulbs have been widely available in many stores throughout the world and price continues to fall. On average they cost in-between $3 and $4 per bulb.

Each CFL bulb can reduce your homes greenhouse gas emissions by several hundred pounds over the course of its lifetime.

While they are slight more expensive than incandescent bulbs, they are often considerably cheaper than light emitting diode fixtures.

Disadvantages of CFL Light Bulbs

Because CFLs are so much more complex than incandescent bulbs they are prone to more errors. This can lead to some CFL bulbs not lasting as long as others even if they're in the same batch.

Research has shown that lower grade CFLs are much more susceptible to dimming than higher quality bulbs. This means you should be careful when choosing your fixtures if you'd prefer them to keep their brightness for many years.

These bulbs contain mercury which is a toxic metal that can be harmful to both humans and the environment if the proper waste management techniques are not employed during disposal.

Because of their design, they usually take a certain amount of time to warm-up to full brightness. This length of time depends on the manufacture; it can range from as little as 30 seconds to as much as three minutes.

LEDs - Light emitting diodes Bulbs

Light emitting diodes are considered by futurist to be the light source of the 21 st century and beyond. This is because unlike incandescent or compact fluorescent bulbs, they don't rely on filaments or toxic vapors to produce light. Instead they utilize semiconductor technology, which is very similar to the technology found in computers, smart phones and other electronic devices we use today.

Compared to compact fluorescent and incandescent bulbs, light emitting diode technology is fairly new. General Electric developed the first LEDs, which produced visible light, in the 1960s. In the beginning LEDs were no more efficient than incandescent bulbs. However, since the turn of the millennium many companies and government agencies across the world have offered incentives to people who come up with ideas to improve the efficiency of this technology.

Since 2008 the cost of LED bulbs has fallen by over 80% and the fixtures available on the market today are six to seven times more energy efficient than standard incandescent lights. Along with this increased efficiency comes a much longer lifespan as some LED lamps can get over 50,000 hours of use. Just as we did with CFL lights, we must take the time to discus both the pros and cons of LEDs.

Advantages of LED Light Bulbs

Some LEDs are capable of outputting 135 lumens/watt making them much more efficient than incandescent bulbs which average 15 lumens/watt.

Unlike CFL bulbs LEDs reach full brightness instantaneously as opposed to having to go through a warm-up period.

LEDs are much more environmental friendly, not only due to efficiency, but also because they don't contain any potentially hazardous material such as mercury.

Because light emitting diodes are based on some of the same fundamental technology that is found in computer chips, they are highly controllable. Depending on the manufacture, the color and brightness for each bulb can be changed at will.

Disadvantages of LED Light Bulbs

Perhaps the main disadvantage of LEDs is their cost. Because the technology is fairly young the initial cost to transition from conventional lighting to LEDs is much more than switching to CFLs. As manufactures develop new methods to make LED bulbs the cost is sure to drop considerably. A great analogy is the mobile phone. In 1983, the first commercially available cell phone cost $4000. Today cell phones start as cheap as $20.

Another disadvantage is that LEDs are directional. For example, this means if you placed one in a table lamp you'd likely get a single beam of light instead of light that radiates throughout the entire room. However, LED manufactures are aware of this and are currently developing ways to defuse the light properly so that it acts more like conventional light bulbs.

From: Tai
We have heard of a ban or phase-out of the Incandescent light bulbs, but was there actually a ban? After two years of the final phase out, of  the traditional 60 watt incandescent light bulbs and nearly a decade after former President George W. Bush made the Energy Independence and Security Act (EISA), people are still wondering: “Were incandescent light bulbs actually banned?
According to the website, not all incandescent light bulbs are banned, only the ones which fail to meet the standards set by the EISA. Therefore, Incandescent light bulb manufactures have to add more energy efficient technology in the bulb.

# data[].attributes.attachment_link.readable_text
Two years after the final phaseout of traditional 60 watt incandescent light bulbs and nearly a decade after former President George W. Bush penned what we know as EISA -- the Energy Independence and Security Act -- people are still wondering: "Were incandescent light bulbs actually banned?"

That's a good question. The answer: yes and no.

Back in December of 2013 and January of 2014, when old 60-watt incandescents were officially phased out, there was a ton of fuss over the so-called "light bulb law." The media was running wild with the story, with CNN even publishing an obituary for the bulbs. And the public was in a tizzy, angry that the government was taking away their basic 25-cent incandescent bulbs.

But it's 2016 and we're still selling incandescent light bulbs here at Regency. Are we breaking the law?

What was banned? Are more light bulb phaseouts ahead?

In spite of some bad reporting a few years back, light bulbs using incandescent lighting technology were not banned by the government. More accurately, save for a few exceptions, any lamp failing to meet the energy standards set by EISA in 2007 could no longer be manufactured. Those lamps were, for the most part, tungsten-filament incandescents.

An FAQs document put out by Energy Star in 2011 explained the new light bulb manufacturing restrictions in this way:

"The standards are technology neutral, which means any type of bulb can be sold as long as it meets the efficiency requirements. Common household light bulbs that traditionally use between 40 and 100 watts will use at least 27% less energy by 2014."

In layman's terms, if manufacturers wanted to sell incandescent light bulbs beyond 2013, they would have to muster up more energy-efficient technology. Today's incandescent lamps are, on average, doubly as efficient as they were when EISA was signed into law, thanks to advancement in halogen technology -- part of the incandescent family. What's more? Most businesses and households have seen enormous savings in energy year over year, thanks to new, more stringent efficiency standards.

Such advancements in efficiency have incandescents trending in the right direction, as the next hurdle EISA has put in the path of lighting manufacturers is yet ahead. In 2020, light bulbs will need to be 60-70 percent more efficient than the standard incandescent on the shelf while Bush was in the White House. Most, if not all, of today's compact fluorescent lamps (CFL) and LEDs have already well surpassed that efficiency threshold, but halogen-based incandescents still have some catching up to do, despite the advancements that came in the scurry up to 2014.

Does the 2020 standard set by EISA spell the end for incandescents? It's tough to say for certain, but major price reductions in CFLs and LEDs have come in recent years. And, considering the drastic contrast in efficiency that these newer technologies afford, along with their drastically longer lifetimes, it's not too hysterical to prophesy of incandescent-less 2020s.

What incandescent bulbs are available today?
Read more: 'What is an incandescent light bulb and how does it work?'
The incandescent light bulbs that emerged as a response to the phaseouts of 2012-14 carry similar lumen outputs to their older counterparts for a typical reduction of 30 percent in wattage. As an example, the equivalent of an old 60-watt A19 incandescent uses 43 watts, on average. The equivalent of an 100-watt A19 incandescent, meanwhile, uses 72 watts for the same lumen output.

There are a couple of caveats which should be noted here. For one, some aren't happy with the color temperature of modern-day halogen-based incandescents, as halogen tends to emit cooler colors than the less-efficient tungsten did. Pre-EISA incandescents might have had a Kelvin temperature of 2400 while today's incandescents will often have a CCT of 3000+ K.

Secondly, as mentioned above, there are a few exceptions, or loopholes, in the switchover to EISA-standard incandescents. Certain applications -- like heat lamps, for example -- were excluded from needing to meet the new standards, leaving the incandescent light bulbs of old still on the market in a very limited fashion.

Incandescent bulbs vs. CFLs

Compact fluorescents were the first lamps to really barge into the market and gain a foothold against incandescents. They've always been much more energy efficient, but have a handful of cons that most businesses and consumers like to weigh into their decision-making process.
Learn more about compact fluorescents in our post, 'What are CFL bulbs and where should they be used?'Comparing average household lamps - Incandescent vs. CFL
Are you looking for LED replacements for pin-based compact flourescents? Or perhaps you're looking into adapters as a CFL to LED retrofit solution?

First, CFLs contain mercury -- a toxic metal which is bad for the environment and people. This means they must be recycled properly. Secondly, a lot of CFLs don't dim, making them incompatible with dimmable fixtures you might have in your building or home. Thirdly, when compared with an incandescent, the color rendering index (CRI) of a CFL is quite limited. Lastly, these lamps come in a spiral shape, causing a lot of people to opt for a traditional bulb-shaped lamp to preserve certain aesthetics wherever the CFLs themselves are visible.

Incandescent bulbs vs. LEDs
Choosing between LED products? Download our LED Buying Guide.
LEDs continue to carve out a bigger and bigger territory in the lighting world. A significant part of that trend is tied to the technology's noteworthy drop in price over the last handful of years, making them immensely more competitive. The other part of that? Energy efficiency, of course. The long lifespans of LEDs combined with their incredibly low energy usage rate give them a corner on the energy efficient lighting market. There is simply no comparison to LEDs in terms of energy efficiency alone.

But if you're familiar with the calling card of LEDs -- energy efficiency -- you're probably equally as familiar with their Achilles heel: cost. LEDs used to cost as much as 40 times more than modern incandescents but, as mentioned above, they've come down in price big time.
Comparing average household lamps - Incandescent vs. LED

Today's LEDs are maybe five or seven times more expensive than a comparably bright incandescent -- two or three times pricier than CFLs. Technologically, however, they're extremely advanced, with some coming with tuning ability for precise color rendering and others able to pump out foreign colors through colorized phosphors.

*LEDs greatly vary in price and features. The above price reflects a middle-of-the-road 60 W-equivalent LED lamp.

There you have it -- all the facts.

Were all incandescent bulbs strictly banned by the federal government? No, they were made dramatically more energy efficient.
Update: Researchers at MIT recently discovered an innovation which could make incandescent bulbs 80 percent more efficient -- greater than the efficiency levels of most of today's LEDs.
Are incandescent bulbs on the verge of being pushed out of the market? Maybe.
