perspectives on arguments 5th edition term papers for sale Lightbulbs were invented 130 years ago and we have come a long way since the original Edison lightbulbs. GE announced this week that this year, it will cease production of its coiled compact fluorescent lamp (CFLs) lightbulbs for the U.S. market and instead focus its consumer lighting efforts on LED lamps.

GE reports that the reason they can make the shift from CFLs to LEDs today is because LED prices have dramatically declined.

That ruling instantly made incandescent lights almost obsolete. The bulbs briefly accounted for about 30 percent of U.S. light bulb sales. But the bulbs, which heat gas rather than a filament, were never really beloved, and last year accounted for just 15 percent of sales. Consumers complained CFL light was too harsh, didn’t work with dimmers, flickered and took too long to warm up and light a room.
pecking order thesis By next year, many CFLs will no longer qualify for the coveted ENERGY STAR rating, which introduced a new lighting specification in January. “These LED lightbulbs are starting to replicate what the electrical filament has done for over 100 years — providing that look and warm ambience that people are used to,” says GE Lighting chief operating officer John Strainic. “The time for LED is now.”

When electricity is applied to an LED, light is emitted from the interface between two different semiconducting materials. LEDs already illuminate everything from gas station signs to flat-screen TVs to retina screens on iPads. With a 22-year life span, a single LED bulb can light a child’s bedroom desk lamp from birth through college graduation.
