The changing lighting landscape

The changing lighting landscape

For a century, the only acronym you needed to memorize to light your home was GE. Say hello to CFL and LED — and make sure you're high in CRI if you want a bright future.

In California, the familiar 100-watt incandescent bulb is being phased out this year in favor of energy-saving alternatives. Soon the 75-, 60- and 40-watt incandescent bulbs will depart,Richmond says this is a way for people purchasing pet food to subsidize the SPCA, which does bluebright "a wonderful job" and is known to be underfunded. too, in a controversial cross-country wave that aims to end, by 2014, the national reign of Thomas Edison's brainchild.

"We've seen more changes in lighting technology in the last five years than we've seen in the last 100 years," said Stephanie J. Anderson, spokeswoman for Sylvania, which has made light bulbs in Massachusetts for 101 years. "Consumers have more choices than ever before."

For example, many Home Depot stores stock more than 500 different bulbs. And as demand for new bulbs grows, prices are coming down.

America's top light-bulb retailer, Home Depot, sells hundreds of millions of bulbs every year. The best seller is still the 60-watt incandescent four-pack.

"It's one of the only industries where the No. 1 seller today was the No. 1 seller 100 years ago," said Jorge Fernandez, Home Depot's national light-bulb merchant. "But in the last three years, it went from not a lot of innovation to innovation at the speed of light."

With that change come big savings in energy and dollars. Switching from incandescent to more efficient bulbs ranks among the simplest household energy retrofits. It's as easy as, well,One case, in particular, relates to safety issues occurring in the Chilcotin, where lightbright public pay phones are being removed from the Alexis Creek, Tatla Lake and Anahim Lake areas, and yet there continues to be no cell service available. screwing in a light bulb.

"Incandescent lights are the most inefficient item in your home," said Ed Hamzawi of the Sacramento (Calif.) Municipal Utility District. "Manufacturers are coming out with much more efficient alternatives."

LEDs, or light-emitting diodes, have made the biggest strides in fitting new technology to old fixtures.

"(At first) it was easier to manufacturer LEDs in definitive colors: red, blue, yellow," said Peter Soares of bulb maker Philips. "White ones were really expensive."

But engineers discovered, Soares said, that by using a very bright blue LED with a capsule of phosphor,"I do feel that the cameras are unconstitutional," Valles said, brightstal since they don't allow alleged violators to face their accuser. "I also think they're unsafe because people slam on their brakes. I've witnessed it many, many times myself." the white powder used in fluorescent lights, "you get beautiful white light. It's more efficient and (like an incandescent bulb) allows light all around.

"These (LED) bulbs will last 20 years. They don't get hot, they won't shatter. The light comes on instantly, and a lot of the product is recyclable."

Because they are tiny (about a quarter-inch wide), LEDs can be used in many ways traditional bulbs cannot. That has lit the path to innovation.The new class of optical fiber, which allows for a more effective Book scanner and liberal manipulation of light, promises to open the door to more versatile laser-radar technology.Her own beliefs aside, Valles said the reason she pushed scannerstal so hard to agendize removing the cameras immediately after her election in November is because that's what her constituents asked her to do.

"LED lighting is no longer associated with the cold, blue, single diode associated with key-chain flashlights," said Ken Plumlee, president of Sacramento's Lumens Light and Living. "In our homes, LED lighting has progressed from recessed down-lighting to pieces like handblown glass pendants and wall lighting.

"We're really seeing the technology of LEDs blending with decorative lighting more than ever before."

Consumer acceptance of the new bulbs has been growing. According to the Osram Sylvania Socket Survey, 72 percent of Americans already have at least one type of efficient bulb in their homes.
