make sure it is energy efficient

Let there be light, and make sure it is energy efficient

Since the late 1800s, consumers have relied on standard incandescent light bulbs to illuminate homes and businesses at the flick of a switch, but this is about to change.

Due to provisions of the Energy Independence and Security Act of 2007, also known as the Clean Energy Act of 2007, incandescent light bulbs will be phased out and replaced by more energy-efficient lighting, including halogen, compact fluorescent, or CFL, and light-emitting diode, or LED, bulbs.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.
General Electric Co., the last U.S. based manufacturer of incandescent light bulbs, closed its plant at the end of 2010.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.
According to GE, the Clean Energy Act requires that between 2012 and 2014, standard A-line 40- and 100-watt incandescent light bulbs must use 30 percent less energy, but produce the same light output as today's incandescent bulb.
While consumers won't be required to throw out existing bulbs, according to GE, "you may be surprised when trying to find the same replacements at the store. After 2012, you'll find that these bulbs will have to be replaced with energy-efficient options, such as halogen, CFL and LED light bulbs."
Richard Wilkins, operations manager for Ulster Electric in Poughkeepsie and Kingston, said that lighting technology is changing every day in an effort to meet demands for energy efficiency.
"There's always something new coming out,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'."" he said. "Lighting technology is going to change within the next 10 to 15 years," he said.
LED lighting, for example, is currently somewhat expensive to purchase but is expected toThe 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.   come down in price, Wilkins said.
"LED lighting offers better light output with less wattage,Badding explained that optical-fiber technology always has been limited by the use dsttマジコン of a glass core. "Glass has a haphazard arrangement of atoms," Badding said. "In contrast, a crystalline substance like zinc selenide is highly ordered. That order allows light to be transported over longer wavelengths, specifically those in the mid-infrared."" he said.
CFL bulbs, Wilkins said, draw a lot less energy but are more expensive to purchase than incandescent bulbs.
New construction projects benefit from tax incentives when installing energy-efficient lighting, Wilkins said.
"Architects are seeing rebates for using energy-efficient products in new construction, including commercial projects," he said.
According to the United States Department of Energy, artificial lighting consumes "almost 15 percent of a household's electricity use."
