Zoinks! Even Santa is getting the LED out!

Its the Holiday Season and running those Christmas Lights can really jack up your energy costs.. A great solution for this is changing for traditional (incandescent) Christmas lights to LED Christmas lights.

Cherie Jacobs, a Progress Energy spokeswoman, says:

Running 10 strands of 100 LED light bulbs during evenings for the month of December will cost about 70 cents.

• Running 10 strands of 100 conventional light bulbs during evenings for the month of December will cost about $7 — 10 times as much.

The Electric Power Research Institute says if seasonal lights nationwide were replaced with LED lighting, carbon emissions could be reduced by as much as 400,000 tons per year and electricity cost savings would exceed $250 million.

Does the latest generation of energy-saving light bulbs save energy? A comprehensive study conducted by Osram, the German lighting company, provides evidence that they do.

Rick Friedman for The New York Times
A standard incandescent bulb over its life will use almost five times the energy of an LED bulb, a German study concluded.

That is because no one knew if the production of LED lamps required more energy than needed for standard incandescent bulbs. While it is indisputable that LEDs use a fraction of the electricity of a regular bulb to create the same amount of light, if more energy were used in the manufacturing and distribution process, then the lighting industry could be traveling down a technological dead end.

The study results show that over the entire life of the bulb — from manufacturing to disposal — the energy used for incandescent bulbs is almost five times that used for compact fluorescents and LED lamps.

The energy used during the manufacturing phase of all lamps is insignificant — less than 2 percent of the total. Given that both compact fluorescents and LEDs use about 20 percent of the electricity needed to create the same amount of light as a standard incandescent, both lighting technologies put incandescents to shame.

“We welcome these kinds of studies,” said Kaj den Daas, chief executive of Philips Lighting North America. The Osram study “provides facts where we often have only emotional evidence.” Philips recently became the first entrant in the Energy Department’s L Prize, a race to develop the first practical 60-watt LED equivalent to a standard light bulb.

To calculate what is know as a Life Cycle Assessment of LED lamps, Osram compared nearly every aspect of the manufacturing process, including the energy used in manufacturing the lamps in Asia and Europe, packaging them, and transporting them to Germany where they would be sold. It also looked at the emissions created in each stage, and calculated the effect of six different global warming indexes.

Those included the amount of greenhouse gas emissions created by each process, the acid rain potential, eutrophication (excessive algae), photochemical ozone creation, the release of harmful chemical compounds, and the resultant scarcity of gas, coal, and oil.

Compact fluorescents also contain harmful mercury, which can pollute the soil when discarded.

In addition to the amount of electricity needed for each process, the energy used and the emissions created as a result, were also calculated. In China and Malaysia, where part of the LED production took place, that meant coal and natural gas respectively. In Germany, where the lamps would be sold, electricity is created from a mix of coal, nuclear and renewable sources.

The methodology followed the procedures set down in ISO 14040/44, an industry standard. The results were certified by three university professors in Denmark and Germany as adhering to the standard.

“The difference in energy use between incandescents, compact fluorescents and LEDs is definitely significant,” said Dr. Matthias Finkbeiner of Berlin’s Technical University and chairman of the study’s review committee. “The results are very stable.”

While 60-watt lamps are more popular light sources, they were not used in the study as Osram does not yet have a commercial version. The amount of energy used to illuminate 60-watt-type lamps would increase, but the increase would effect all types of lamps and therefore not change the relative results, according to Dr. Berit Wessler, head of innovations management at Osram Opto Semiconductors in Regensburg, Germany.

Dr. Wessler expects the results to shift even more in favor of LEDs, as newer generations of that technology become even more efficient, requiring less energy to produce the same amount of light.

“Everything I’ve seen strengthens the assumption that LED efficiency will increase,” she said. “There has not been much improvement in incandescent efficiency in the last 10 years.”

Zoinks! Check Out Physicist David Mackay’s video of how  the  light bulb  provides a graphic way of communicating to non-physicists the scale of the energy gap now facing our society! Light bulbs will always lead the way for me!

Dr. Z


Zbulbs: Make the Switch!

Cambridge University physicist, David Mackay, in a passionate, personal analysis of the energy crisis in the UK, in which he comes to some surprising conclusions about the way forward. The film is based on his new book Sustainable Energy without the hot air, in which Prof Mackay has calculated the numbers involved for the alternatives to fossil fuels like coal, gas and oil.

He debunks some myths about energy saving – unplugging our phone chargers, does not make any appreciable difference. After showing us what won’t work – he goes on to show what will make a difference at home, like turning your thermostat down.

But, his big point is that this will not be enough – individual efforts are not enough. Instead we need to make sweeping national changes to our energy production, and we can’t reject everything available to us. If we are going to follow the advice of climate scientists, and get off fossil fuels by 2050, which currently provide 90% of our energy, Britain’s main options are wind power and nuclear power. But to make this huge change in our power supply, Mackay says that we have to get building now!

Resistance to EU’s lightbulb ban By Henry Chu Los Angeles Times

FRANKFURT, Germany – Ulf Erdmann Ziegler takes a dim view of the newfangled lightbulbs people are required to buy, so dim that he has stocked up on 3,000 of the old, incandescent bulbs – enough, he has calculated, to last him his lifetime. His stockpile is the fruit of a frenzied shopping spree. For weeks, he spent many of his waking hours on the phone and online tracking down vendors and snapping up incandescent bulbs. The buying binge was necessary, he said, to beat a ban by the European Union. As of Sept. 1, the manufacture and import of 100-watt incandescent bulbs have been outlawed within the EU, to be followed by bulbs of lesser wattage in coming years. Once current stocks are gone, incandescent bulbs will join Thomas Edison in the history books. The ban is part of the EU’s effort against global warming. The object is to encourage people to switch from energy-wasting incandescent bulbs to compact fluorescent lamps, which last longer and are up to 75 percent more efficient. For EU officials, it’s all about the math. Ditching the older bulbs, they say, will save 40 billion kilowatt-hours a year by 2020 – equal to the output of 10 power stations. The United States is to begin phasing them out in the next few years. But not everyone considers it such a bright idea. Dissenters have sprung up across the Continent, people who complain that fluorescent lamps are inferior, cost more, and pose their own environmental problems. Art galleries fret over how best to display their works without the warm glow of incandescent bulbs. A petition to save the conventional bulb is circulating on the Internet. “There’s been quite a bit of consumer backlash,” said Peter Hunt, chief executive of Britain’s Lighting Association. To help consumers and manufacturers get used to the change, the EU decided not to ax all incandescents at once. The ban from September covers only clear bulbs of 100 watts and frosted ones of all wattages. Clear incandescent lamps of 60 and 40 watts are to be eased out by September 2012. The advantages of the ban outweigh any deficiencies, EU officials say. Good-quality fluorescent bulbs can last years, far longer than conventional bulbs, so while they cost more, they are more economical in the long run. The new lamps also save on electricity costs because of their more efficient use of energy. In conventional bulbs, most of the energy is lost as heat rather than converted to light. Then how to explain that low-energy fluorescent lamps have been around for 25 years but have never caught on with ordinary consumers? “The early ones were the size of large jam jars, they flickered, they had a cold blue light, and they took a long time to switch on,” Hunt said. The technology has improved considerably, Hunt said. None of that matters to Ziegler. Months before the Sept. 1 deadline, he went through every room of his apartment with a floor plan, marking an X wherever there was a light fixture and noting what kind of bulb it required. His local vendor worked out how many bulbs Ziegler would need for the next decade. “I said forget 10 years,” Ziegler recalled. “I want a lifetime supply.”

Zoinks! Have you heard about the latest fashion coming out of Japan? LED Eyes! Check out this from the Dangerous Minds Blog!

Dr. Z

https://www.zbulbs.com/

I know the LED Eyelash craze is sorta old news. However, I’ve never seen the video of the eyelashes in action.

LED Eyelash is a clever product that speaks to many Asian women’s desire for bigger eyes. It features an inclination sensor with mercury to turn on and/or off. The sensor can perceive the movements of the pupil in the eyes and eyelids. If someone wears it and moves her head, LED Eyelash will flicker following the movement.

Germans torn between incandescent and fluorescent

Germans torn between incandescent and fluorescent

ZOinks! The Controversy over the European Incandescent Light Bulb Ban continues. This Oct 17th article from the LA Times gives the lowdown..

-Dr. Z

https://www.zbulbs.com/

Reporting from Frankfurt, Germany – Here’s a twist: How many lightbulbs does it take to change a person?

For Ulf Erdmann Ziegler, the answer is 3,000. That’s how many bulbs are squirreled away in his modest apartment here in Frankfurt, the number that turned an otherwise ordinary guy into a hoarder, made him the object of his neighbors’ pity and got him thinking about death and divorce.

His enormous stockpile is the fruit of a frenzied summer shopping spree. For weeks, he spent many of his waking hours on the phone and online tracking down vendors and snapping up enough incandescent bulbs to last him the rest of his life.

The buying binge was necessary, he said, to beat a ban by the European Union. As of Sept. 1, the manufacture and import of 100-watt incandescent bulbs have been outlawed within the EU, to be followed by their dimmer brethren in coming years. Once current stocks are gone, such bulbs will join Thomas Edison in the history books.

“It will run out,” Ziegler warned of the limited supply, “and everyone will be sorry.”

The ban is part of the EU’s effort to retard global warming. The object is to encourage people to switch from traditional energy-wasting incandescent bulbs to compact fluorescent lamps, which last longer and are up to 75% more efficient.

For EU officials, it’s all about the math. Ditching old-fashioned bulbs, they say, will save nearly 40 billion kilowatt-hours a year by 2020, equivalent to the output of 10 power stations. Australia has already abandoned incandescent bulbs, and the United States is set to begin phasing them out in the next few years as well.

But not everyone considers it such a bright idea. The ban has been met with some resistance in Europe, showing what happens when the collective goal of greening the planet clashes with issues of individual choice and even aesthetics.

Dissenters such as Ziegler have sprung up across the continent, people who complain that fluorescent lamps are inferior, more expensive and come with their own environmental problems. Art galleries fret over how best to display their works without the warm glow cast by incandescent bulbs. A petition to save the conventional bulb is circulating on the Internet.

There have also been reports of runs on lighting stores. In Britain, where major retailers began taking 100-watt incandescent bulbs off their shelves even earlier, in January, a retired teacher in southern England spent $800 of her pension to buy 1,000 of them.

“There’s been quite a bit of consumer backlash,” acknowledged Peter Hunt, chief executive of Britain’s Lighting Assn. “A lot of it we expected.”

To help consumers and manufacturers get used to the change, the EU decided not to ax all incandescent bulbs at once. Last month’s ban covers 100-watt clear bulbs and all frosted ones. Clear 40- and 60-watt incandescents are to be eased out by September 2012.

The advantages of the ban outweigh any deficiencies, EU officials say. Good-quality fluorescent bulbs can last years, many times the life span of regular bulbs, so although they cost more, they are more economical in the long run.

The new lamps also cut electricity bills because of their more efficient use of energy. In conventional bulbs, most of the energy is lost as heat rather than converted to light.

“You can . . . look at it the same way that you’re looking at improvements of washing machines and fridges, where consumers don’t even notice that the fridges [have] become more efficient,” said Andras Toth, a policy officer in the EU’s energy directorate.

Maybe. But then how to explain that low-energy fluorescent lamps have been around for 25 years but have never caught on with consumers? Though he supports the switch-over, Hunt acknowledges that there were good reasons why fluorescent bulbs were passed over on store shelves.

“The early ones were the size of large jam jars, they flickered, they had a cold blue light and they took a long time to switch on,” he said. “So it’s not surprising that consumers have a bad preconception of this lighting.”

The technology has improved considerably on all those counts, Hunt said. But fluorescent bulbs haven’t shaken their bad rap.

Their start-up time still lags well behind the instant on-and-off of incandescent bulbs. They cannot be used with dimmer switches. And the most commonly available ones still do not provide the same spectrum of light as the old lamps, which worries art collectors, photographers and others who need light sources that offer sharp color rendition. (Officials point out that halogen bulbs, which give off light of a similar quality to incandescent varieties, remain on the market.)

Then there is the fluorescent bulbs’ mercury content, up to 5 milligrams per bulb. Cleaning up a shattered bulb requires more than just sweeping up jagged shards: Users should ventilate the room and avoid touching pieces with bare skin.


Still, “if you compare it to other mercury content, like dental fillings, the amount we’re talking about is really rather small,” Toth said. “And you have to be extremely unlucky to be exposed to it in a dangerous way.”

None of that cuts any ice with Ziegler.

A writer and former art critic, he sees the EU’s ban as unnecessarily extreme. Why not slap a tax on the old-fashioned bulbs, rather than outlaw them entirely?

“The law just says you can’t use the best lightbulb ever invented,” he grumbled.

A few months ago, with the Sept. 1 deadline looming like a neon sign, he decided to take preemptive action.

With typical German precision, he went through every room of his apartment with a floor plan in hand, marking an X wherever there was a light fixture — about 25 in all — and noting what kind of bulb it required. Then he took the checklist to his local vendor, who worked out how many bulbs Ziegler would need for the next decade.

“I said forget 10 years,” Ziegler recalled. “I want a lifetime supply.”

That, though, posed an unanticipated question. At 50, he suddenly had to ponder — or guess — how much longer he expected to live. He drafted his wife into his existential contemplations, and together, like actuaries, they finally decided that a lifetime supply meant enough bulbs to last 30 years.

Laying his hands on 3,000 incandescent bulbs was another story. He cleaned out one supplier and went on to the next, seeking them out on the Internet. Bulky packages kept arriving at the apartment, and “I was not unaware of the pitying looks of my neighbors,” he confessed in a newspaper column.

Thankfully, his wife supported his panic buying, because she “hates [fluorescent bulbs] even more than I do,” Ziegler said.

But that sparked yet another uncomfortable discussion. Who gets custody of the hoard in case of divorce? (Stay tuned.)

For now, the incandescent cache is carefully stowed away in the attic, to which Ziegler disappears to extract an unusually shaped bulb to show a visitor the way a wine lover might disappear down the cellar to produce a prized bottle of Chateau Lafite Rothschild.

Ziegler still hopes the EU ban will somehow fail, or be repealed. He’s mulling the idea of writing a political manifesto on behalf of the incandescent bulb, laying out its history and its merits.

And he urges people to build their own stockpiles as soon as they can, before supplies dry up.

“If you want to get in on it, get in,” he said. “It’s not too late.”

Dude! Save Incandescent they are a wicked electro clash band...

Dude! Save Incandescent they are a wicked electro clash band...

 


By HOWARD M. BRANDSTON

The Energy Independence and Security Act of 2007 will effectively phase out incandescent light bulbs by 2012-2014 in favor of compact fluorescent lamps, or CFLs. Other countries around the world have passed similar legislation to ban most incandescents.

Will some energy be saved? Probably. The problem is this benefit will be more than offset by rampant dissatisfaction with lighting. We are not talking about giving up a small luxury for the greater good. We are talking about compromising light. Light is fundamental. And light is obviously for people, not buildings. The primary objective in the design of any space is to make it comfortable and habitable. This is most critical in homes, where this law will impact our lives the most. And yet while energy conservation, a worthy cause, has strong advocacy in public policy, good lighting has very little.

Even without taking into account people’s preferences, CFLs, which can be an excellent choice for some applications, are simply not an equivalent technology to incandescents in all applications. For example, if you have dimmers used for home theater or general ambience, you must buy a compatible dimmable CFL, which costs more, and even then it may not work as desired on your dimmers. How environmental will it be for frustrated homeowners to remove and dispose of thousands of dimmers? What’s more, CFLs work best in light fixtures designed for CFLs, and may not fit, provide desired service life, or distribute light in the same pleasing pattern as incandescents. How environmental will it be for homeowners to tear out and install new light fixtures?

None of these and other considerations appear to have been included in the technical justification for this law. Instead, the decision appears to have been made entirely based on a perception of efficiency gains. Light-source efficacy, expressed as lumens of light output per watt of electrical input, has been used as a comparative metric justifying encouragement of CFLs. But this metric is flawed for one simple reason: It is a laboratory measurement and a guide, not a truth, in the field; actual energy performance will depend on numerous application characteristics and product quality.

If energy conservation were to be the sole goal of energy policy, and efficacy were to be the sole technical consideration, then why CFLs? If we really want to save energy, we would advocate high-pressure sodium lamps—those large bulbs that produce bright orangish light in many streetlights. Their efficacy is more than double what CFLs can offer. Of course this would not be tolerated by the public. This choice shows that we are willing to advocate bad lighting—but not horrible lighting.

Not yet, at least. Energy regulations pending in Washington set aggressive caps on power allowances for energy-using systems in commercial and residential buildings. These requirements have never been tested.

Here’s my modest proposal to determine whether the legislation actually serves people. Satisfy the proposed power limits in all public buildings, from museums, houses of worship and hospitals to the White House and the homes of all elected officials. Of course, this will include replacing all incandescents with CFLs. At the end of 18 months, we would check to be certain that the former lighting had not been reinstalled, and survey all users to determine satisfaction with the resulting lighting.

Based on the data collected, the Energy Independence and Security Act and energy legislation still in Congress would be amended to conform to the results of the test. Or better yet, scrapped in favor of a thoughtful process that could yield a set of recommendations that better serve our nation’s needs by maximizing both human satisfaction and energy efficiency.

As a lighting designer with more than 50 years of experience, having designed more than 2,500 projects including the relighting of the Statue of Liberty, I encourage people who care about their lighting to contact their elected officials and urge them to re-evaluate our nation’s energy legislation so that it serves people, not an energy-saving agenda.

Is this the light bulb of the future?

Is this the light bulb of the future?

The ubiquitous but highly inefficient 60-watt light bulb badly needs a makeover. And it could be worth millions in government prize money — and more in government contracts — to the first company that figures out how to do it. Right now, that company could be Philips, the Dutch electronics giant. The company announced on Thursday that it had submitted the first entry for the L Prize, a Department of Energy contest that will award up to $10 million to the first person or group to create a new energy-sipping version of the most popular type of light bulb used in America. As the first entrant, Philips will win the prize if its claims hold up. Testing of the Philips lamp will take close to a year as the department evaluates the company’s claims. “Philips is confident that the product submitted meets or exceeds all of the criteria for the L Prize,” said Philips Lighting chief Rudy Provoost. The $10 million is almost beside the point: The contest winner will receive consideration for potentially lucrative federal purchasing agreements, not to mention a head start at cracking a vast consumer marketplace. The L Prize has gained significant attention in the lighting industry because 60-watt incandescent lamps represent 50 percent of all the lighting in the United States, with 425 million sold each year. The Energy Department says that if all those lamps were LED equivalents, enough power would be saved to light 17.4 million American households and cut annual carbon emissions by 5.6 million metric tons annually. For decades, incandescent light bulbs continued to bear a strong resemblance to Thomas Edison’s creations, but new energy standards that go into effect in 2012 — and would outlaw today’s incandescent bulb — have brought about a period of fertile innovation in the lighting industry. One of the first attempts at greater efficiency was the now-maligned compact fluorescent bulb, but there have also been efforts to modify incandescent technology to conform to the new standard. LED bulbs are already available in stores, but those models have limited output and high prices. A faithful reproduction of an incandescent bulb’s light from an inexpensive and efficient source has been the industry’s ultimate goal. Philips has delivered 2,000 prototypes of its bulb to the Energy Department for testing. The company says the bulbs meet all the contest criteria, which specify a bulb that reproduces the same amount and color of light made by a 60-watt incandescent bulb, but uses only 10 watts. The bulb also must last for more than 25,000 hours — about 25 times longer than a standard light bulb. In a nod to economic concerns, at least 75 percent of the bulb must be made or assembled in the United States. At first, the department set no standards for compact fluorescent bulbs, and inferior products flooded the market. Consumers rebelled against the bulbs’ shortcomings: The light output from compact fluorescent bulbs was cold and unpleasant, their life was much shorter than claimed, many were large and undimmable, they would not work in cold environments and they contained polluting mercury. By setting rigorous criteria for the L Prize, the department hopes LED bulbs can avoid a similar fate. That also means rejecting current LED bulbs that can claim some technical similarities, but fall far short of the L Prize’s goals.

This could happen to you

This could happen to you

Gadzooks! Its already the time to start thinking about putting up christmas lights! So I figure it would be good to post a few tips on how to go about creating your own little winter wonderland.  Ann Belvins from Better Homes and Gardens gives 13 tips for setting up a dazzling christmas display!

Dr. Z

www.zbulbs.com

 

1. Start out small. If you’re a Christmas lights novice, light just two or three items, such as trees or bushes, to serve as focal points. Add new displays each year.

2. Stay safe. Only use lights with the UL (Underwriters Laboratories) label and be sure you’re using lights designed specifically for outdoor use.

3.Know your lights. When it comes to holiday lights, there’s a type available for every nook and cranny of your house and yard. Whether you want blinking rope lights outlining windows or net lights blanketing bushes, wising up on your holiday light knowledge will help you get the most bang for your buck.

4.Check for burned-out lights. Test light strings and replace any burned-out lights before decking the halls. Burned-out lights drain power from the entire light string, and the other bulbs will grow dimmer.

5. Out with the old, in with the new. Avoid old-fashioned nails, staples, screws, or hooks when mounting your display. Electrical tape is a quick and easy alternative — it won’t destroy your roof, and it’s a good tool for protecting electrical connections. Clips, such as shingle tab or parapet clips, hold lights to surfaces by applying simple, safe pressure.

6.Use a sturdy ladder. Enlist a helper to keep you steady as you hang lights on very tall tree — you’ll stay safe and you’ll be able to reach the branches easily. Attach lights to branches with tree clips or twist ties.

 7. Work your way up. To string trunks of deciduous trees, start at the base and wrap the lights around in a spiral. If you want to illuminate an evergreen, however, start at the top and zigzag lights through the center of the tree, getting wider with the tree’s shape

8. Consider the location. If your evergreen can only be seen by passersby from the front, save lights and work by decorating the tree front only.

9. Add some dimension. Consider ground and stake lighting for extra holiday oomph. Multicolored lights work well for outlining walks, paths, and driveways.

10.Avoid bright light overload. Holiday lights can be dazzling and fun, but be careful not to overload your circuits. Include no more than 1,400 watts on a circuit. If other lights in the house dim when you turn on the holiday lights, your circuit is overloaded.

11.Look around for added sparkle. Find illuminating inspiration in unexpected places. Perhaps a birdbath or decorative porch columns would look pretty with a little extra light. For hard-to-reach spots, or any place you don’t want to use electricity, try battery-operated mini lights.

12.Call in the pros. If you don’t have roofing experience, limit your lights to eaves, gables, and the edge of the roof. Keep lights and cords away from metal. Beware of overheated wires, aluminum gutters, and ironwork decor. If you want more lights on the roof itself, call a professional lighting company.

13.Hit the switch. Turn off outdoor lights before going to bed, and don’t leave them on when you’re away from home, unless they’re attached to a timer with a photocell.
