Light bulb phaseout can't dim Edison's incandescence

Light bulb phaseout can't dim Edison's incandescence

Consumers may not all be aglow with the idea,"The trick was to get this compound into a fiber dstti structure, something that had never been done before." Using an innovative high-pressure chemical-deposition technique developed by Justin Sparks, a graduate student in the Department of Chemistry, Badding and his team deposited zinc selenide waveguiding cores inside of silica glass capillaries to form the new class of optical fibers. but the government-mandated phaseout of incandescent light bulbs has reached all the way to the winter home of Thomas Edison.
Under a 2007 federal energy law, manufacturers must phase out incandescent bulbs in favor of more efficient bulbs such as compact fluorescent lamps, or CFLs, LED bulbs or new styles of halogen lights.


The law phases out 100-watt incandescent bulbs in January 2012, followed by the 75-watt version in 2013 and the 60- and 45-watt bulbs in 2014.

At the Edison & Ford Winter Estates in Fort Myers, the incandescent garden lights have been replaced, even though Edison is credited with making the first practical incandescent light.


“Edison would have been all for this, because he was always looking for a better way to do something,” said Chris Pendleton, CEO of the estates.


While CFLs use at least 75 percent less energy,Corrine Grimley Evans, a spokesman for the Oxford Pedestrians cfl bulbs Association, said the county council's plans for a redesign involving roundabouts would improve life for those on foot. some consumers complain the lighting is dimmer, doesn’t look as warm and takes a while to reach full brightness. Some also worry about disposal requirements, because the bulbs contain a few milligrams of mercury.


“Every time I go to the store, I pick up a few (incandescent) light bulbs,” said Kay Horn, 62, of Fort Myers. “I probably have enough light bulbs for the next 15 years.”
Jack Lurie, owner of Tropical Hardware in Fort Myers, said he hears customers complain about the phasing out of incandescent bulbs and he said their sales have increased.


“There is plenty of stock now,” he said, “but that will change.”


The American Lighting Association’s Larry Lauck hasn’t seen statistical signs of stockpiling but has heard anecdotal reports.


Such reports are common whenever a new standard is introduced, says the Natural Resources Defense Council’s Noah Horowitz. He says consumers will be able to buy incandescent, but new ones will have more efficient halogen capsules.


“Unless you prefer paying higher electricity bills, there’s no reason to hoard old incandescent bulbs,” Horowitz says.


Richard Downing, 81,The lights, which change colour, are part sky lanterns of the continuing overhaul of the centre. Plans are currently underway to install new tiered seating in the main auditorium which is due to be completed in the summer.   of Fort Myers has been using CFL bulbs in his home for almost 10 years. He has been a fan of fluorescent bulbs for 30 years,He said that a county council employee had witnessed a near miss between led lamp a car and cyclist, and he added: "If the argument is leave them off for good, then the answer is ‘no'." since he installed them on a 40-foot ketch.


“They drew the battery down a heck of lot less,” he said.


He said he is concerned about the bulbs’ mercury content, mainly because he worries consumers will just toss them in their garbage.


“You aren’t supposed to do that, but you know people will,” Downing said.


Lee County’s recycling program won’t collect the CFL bulbs, but homeowners can drop them off at the Household Chemical Waste Collection facility, 6441 Topaz Court in Fort Myers.


While that sounds inconvenient, Downing said he can’t say whether it is.
“In 10 years of using those lights,CALLS have been made to turn off the lights at one of led lighting Oxford's busiest junctions, after the traffic ran more smoothly when they failed. I’ve never had to replace one,” he said. “They might cost just a little more, but you make up what you spend very quickly in the energy savings and longevity.”
