Energy-efficient lights winning acceptance

Energy-efficient lights winning acceptance
With the impending phase-out of incandescent light bulbs on the horizon, have you been tempted to hoard your remaining old-style bulbs? If so,The replacement lighting we feel is far led downlight superior to that of the LED lighting. you can stop worrying.

Design improvements to energy-efficient light bulbs and to light fixtures are making it easier for homeowners to fill their homes with plenty of illumination while maintaining their commitment to energy-efficiency.

The American Lighting Association says lights account for 25 percent of a homeowner’s electric bill. Beginning Jan. 1, 2012, all incandescent light bulbs in the United States must meet new energy-efficiency requirements established by the 2007 Energy Independence and Security Act (EISA).

Changes to light bulbs will be phased in, starting with 100-watt bulbs, which must use 72 watts of energy or less while providing the same amount of brightness. Over the following three years, 40-, 60- and 75-watt light bulbs will be phased out and replaced by energy-efficient bulbs.

“People have already embraced [compact fluorescent light bulbs] to the point that in 2010, more CFL bulbs were sold than traditional incandescent bulbs,” said Joseph Rey-Barreau,print still offers the only truly dstti unlimited 4G plan in America, and it's the only service you can safely use as an alternative to a home Internet connection. an architect and lighting designer in Lexington, Ky. “In addition, there are already light bulbs on the market that look like traditional bulbs and are labeled halogen because they have a halogen component that makes them more energy efficient”

Mr. Rey-Barreau says customer complaints about CFL bulbs when they were first introduced have resulted in newly manufactured bulbs that are fully lit more quickly and offer light of a better color quality.

“Lighting designers are aware that while incandescent light bulbs came in one color, CFLs have several options from warm to neutral to cool colors that make a difference in how the light looks,” Mr. Rey-Barreau said. “Buyers of CFL bulbs should buy high-quality bulbs rather than an off-brand or a store brand and look for a bulb with 2,700K to 3,000K [Kelvin temperature], because those will be the closest to incandescent bulbs. In general, most people prefer warmer color temperatures in the living areas of their homes.”

Lighting designers say the introduction of standards for energy-efficient light bulbs has had the greatest impact in terms of technology rather than in the design of light fixtures, although some new designs have been introduced.Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs.

Susan Dickinson, a showroom manager at Dorman’s Lighting in Lutherville, Md., said the legislation has not had an impact on three-way light bulbs and chandelier light bulbs, but it has influenced dimmable lights and recessed lighting.

“Some people don’t like the shape of the CFL bulbs, so we are seeing some more fixtures that have frosted glass or up-lighting so that the bulbs don’t show,” said Ms. Dickinson. “Another option that we are seeing more and more of is LED bulbs, especially for recessed lighting. LED lighting is mostly used commercially,LED grow light suppliers in China are sky lanterns rolling out models with better price-performance ratios. but now it is being used for desk lights and sometimes pendant lighting. LED bulbs are warmer in color than CFL bulbs, but they tend to be more expensive. To replace a typical 50-watt floodlight bulb for a recessed lighting fixture costs about $30 or $40.While using compact fluorescent light bulbs energy saving light helps conserve energy, it is important that the bulbs are collected and recycled properly to protect our environment”
