Green Promise Seen in Switch to LED Lighting

To change the bulbs in the 60-foot-high ceiling lights of Buckingham Palace’s grand stairwell, workers had to erect scaffolding and cover precious portraits of royal forebears.
To change the bulbs in the 60-foot-high ceiling lights of Buckingham Palace’s grand stairwell, workers had to erect scaffolding and cover precious portraits of royal forebears. So when a lighting designer two years ago proposed installing light emitting diodes or LEDs, an emerging lighting technology, the royal family readily assented. The new lights, the designer said, would last more than 22 years and enormously reduce energy consumption and carbon dioxide emissions — a big plus for Prince Charles, an ardent environmentalist. Since then, the palace has installed the lighting in chandeliers and on the exterior, where illuminating the entire facade uses less electricity than running an electric teakettle. In shifting to LED lighting, the palace is part of a small but fast-growing trend that is redefining the century-old conception of lighting, replacing energy-wasting disposable bulbs with efficient fixtures that are often semi-permanent, like those used in plumbing.
car and house insurance Studies suggest that a complete conversion to the lights could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent dental insurance in Ohio in just over 20 years; in the United States, lighting accounts for about 6 percent of general accident insurance company all energy use. A recent report by McKinsey & Company cited conversion auto comparison insurance rate to LED top rated insurance companies lighting as potentially the most cost effective of a number of car insurance in Alabama annual travel insurance uk simple approaches to tackling car insurance companies in ontario global home insurance rate quote warming using existing technology. LED lighting was once relegated to basketball pyramid insurance scoreboards, cellphone unitedhealthcare insurance consoles, mcgraw insurance traffic lights and colored Christmas lights. But as a temporary auto insurance result of rapid developments in the technology, it is now poised to nc disability insurance dental insurance ma become common on streets and in buildings, as dental insurance in SC well as trade liability insurance in homes and offices. Some American cities, including Ann Arbor, Mich., and Raleigh, N.C., are using the garage liability insurance lights to illuminate streets and parking garages, and rav4 insurance dozens more are exploring the technology. holistic insurance And the lighting now adorns the credit insurance broker conference rooms and bars of some Renaissance hotels, a corridor in the Pentagon and car insurance motor quote a new green building at Stanford. LEDs are more than twice as efficient as compact fluorescent bulbs, currently the standard canada life insurance company for greener lighting. atlanta car insurance Unlike compact fluorescents, LEDs turn on quickly and business flood insurance are compatible car insurance advice with dimmer switches. And while fluorescent bulbs contain mercury, which requires special disposal, georgia car insurance company LED bulbs contain no toxic boat trailer insurance elements, and last so long that disposal is online mobile home insurance quote not much allied insurance group of kennel club dog insurance new jersey title insurance rates an issue. “It is fit-and-forget-lighting that comprehensive liability insurance is essentially there for condo liability insurance as long as you live,” said insurance van nuys Colin Humphreys, a researcher at Cambridge University who works car insurance in Oregon single premium life insurance on gallium nitride car insurance kansas city LED lights, which now adorn structures in Britain. The switch to LEDs is proceeding far more rapidly than experts had predicted just two alabama dental insurance years ago. President Obama’s stimulus package, which offers money for “green” infrastructure investment, will accelerate that pace, experts say. auto insurance farm San Jose, Calif., plans to use $2 million in eyeglass insurance energy-efficiency grants auto car insurance rental to install 1,500 jukes insurance LED streetlights. Thanks in part to the injection of federal cash, sales of the lights in new “solid state” fixtures — a $297 million industry in 2007 — are dental hygienist liability insurance likely to become a near-billion-dollar industry by 2013, said Stephen Montgomery, director of LED research projects metropolitan casualty insurance company at Electronicast, a California consultancy. And after years car cheap driver insurance woman of resisting what they had dismissed as wawanessa car insurance a fringe technology, giants like General Electric and Philips have begun making LEDs. Though the United States Department of Energy calls LED “a pivotal emerging technology,” there remain significant insurance accounting software barriers. Homeowners may balk at the car insurance northern ireland high initial cost, psychiatry malpractice insurance which get disability insurance insurance marketing software lighting experts car insurance america new hampshire dental insurance say currently will take 5 to auto insurance in Memphis 10 years to recoup in vgli insurance eco car insurance electricity savings. An outdoor LED spotlight today costs $100, as opposed to $7 for a regular bulb. Another issue is that current LEDs generally provide only “directional light” rather than auto insurance underwriter a 360-degree glow, meaning they are better suited to southern insurance downward facing streetlights and ceiling home title insurance lights than to business insurance rates ski insurance europe many lamp-type settings. And in the rush to make cheaper cover insurance mortgage payment LED lights, poorly goldfish travel insurance made products could erase the technology’s natural advantage, experts warn. LEDs are tiny sandwiches of two different materials medical insurance in Indiana texas business insurance that release light as electrons insurance turkey jump from one to the other. The lights liability insurance requirements must be carefully designed so heat does not damage them, reducing their lifespan to months from decades. oregon car insurance quote And technological advances that receive insurance automation rave reviews in a university laboratory may not perform colombia travel insurance as well when mass produced for the canadian auto insurance quotes real world. Britain’s Low Carbon Trust, an environmental nonprofit group, has replaced the 12 LED fixtures bought three florida motorcycle insurance years ago for its offices with conventional bulbs, commercial vehicle insurance because the LED lights were not bright enough, said Mischa homeowners insurance ohio Hewitt, a program manager at the trust. But he says he still thinks the technology is important. Brian Owen, a medical insurance in FL geico direct car insurance contributor to the trade magazine LEDs, said uk fleet insurance spanish home insurance that while it is good that cities are exploring LED small group dental insurance lighting: “They have to alternative medicine insurance do their due diligence. Rash decisions can result in disappointment or disaster.” At the same time, competitive car insurance nearly monthly scientific advances are washington dc dental insurance addressing many of the problems, piaggio moped insurance decreasing the high price of the bulbs somewhat and improving their ability to long term care insurance rate provide normal white light bright enough to illuminate rooms and streets. “This is a technology on a very fast learning curve,” said cat d insurance loss Jon Creyts, bmw auto insurance an author of the McKinsey report, who predicted that the insurance management software alberta auto insurance quote technology anthem dental insurance could be ontario online car insurance quote in widespread supercar insurance use within five years. So far, the use of LEDs has been ami insurance nz predominantly in outdoor settings. Toronto, Raleigh, Ann Arbor budget insurance services health insurance carrier and Anchorage — not to mention Tianjin, China, and Torraca, Italy — have adopted LEDs for car geico insurance quote street and parking garage lighting, gastric bypass surgery insurance forsaking the yellow cheap car insurance for young drivers glow of traditional high-pressure sodium lamps. europe insurance single travel trip travel insurance turkey Three major California homeowners insurance houston cities — Los Angeles (140,000 streetlights), San Jose (62,000) and San Francisco (30,000) survivorship life insurance — have embarked on some LED conversions. Ann Arbor adopted the technology car insurance in Seattle early, working with Relume Technologies, of Oxford, Mich., to design LEDs that would fit the globes all kids health insurance of downtown fixtures. The $515 cost of installing each light will be paid back in reduced maintenance and electrical costs in four years auto insurance quote toronto and four months, said Mike Bergren, the credit card rental car insurance city’s field-operations manager. Because the light from LEDs can complementary therapy insurance be modulated, sports liability insurance in Ann Arbor disability insurance rates they have been programmed to perform various useful tricks — to become brighter when someone walks under a light windstorm insurance home insurance online or to flicker outside of a home to guide paramedics to an emergency. And because they do impreza insurance not emit buy boat insurance ultraviolet light, they attract no bugs. People who live around Carolina Pines Park in Raleigh say they are pleased with the park’s new best dental insurance coverage LED lights because mha insurance company they can be directed alfa car insurance downward, away from home windows. The lights are medicare advantage insurance also rapidly moving indoors, where they could have an enormous effect on climate change. About 20 percent of american general insurance company carbon dioxide emissions associated with buildings in car insurance credit report the United States and the United Kingdom are related to indoor lighting; in some houses the number is as high as 40 percent. This month, LED lights were for the first time the centerpiece at car classic hagerty insurance two of the boat insurance maryland world’s major trade shows for lighting, Lightfare International in home insurance wa New York 21st Century auto insurance and EuroLuce in Milan. A car classic insurance texas growing number of builders are starting to fit them into public first time car insurance buildings, offices and homes. Ted business insurance ny Van travel insurance new york Hyning, director of event technology at the Renaissance Hotel in Cleveland, said the new LED lights national insurance state pension in the hotel’s conference rooms use 10 percent mortgage repayment protection insurance of the electricity concord auto insurance of the fluorescent backpacker annual travel insurance lights they replaced. parrot pet insurance And maintenance costs are far first commercial insurance company lower: A fluorescent bulb might last 3,000 hours while an LED supplemental hospital insurance fixture lasts more than 100,000 hours, Mr. Van Hyning said, adding: “We have low cost travel insurance six-figure energy costs a year, and these lights could represent a huge saving. probuilders specialty insurance Besides, they’re cool and sickness employment insurance sexy and fun.” Buoyed by the improvements in the technology, Peter Byrne, a lighting designer and energy consultant for Buckingham Palace, installed the 32,000 custom LEDs in the all kids insurance alabama ceiling of the grand stairwell when older fixtures wore out. Mr. Byrne recognizes that Buckingham Palace is not the average home. travel insurance northern ireland “They need high-quality light — they have a lot of gold,” he said, “and gold tends to look pha travel insurance silver if motorcycle insurance australia you light it poorly.” Still small business product liability insurance he has started using the technology in other projects, for their accident insurance uk low cost term life insurance quote light and their environmental benefit. He estimates that half of antique car classic insurance lights in ontario car insurance free quote homes, and particularly those in offices and stores can already be replaced by LEDs. “At this point, LEDs can’t be used in all lights but that’s title insurance fee changing every month,” Mr. Byrne said. “If you go into Wal-Mart, and look at all those twin 8-foot fluorescents above every grundy classic car insurance aisle, you realize that the potential is enormous.”
