GE recently made news by announcing a new 40-watt replacement LED bulb expected to consume just 9 watts and last around 17 years. One wouldn’t expect GE’s groundbreaking announcement to go unchallenged, however, and now Lighting Science Group (LSG) has responded with its own new Definity line up of LED bulbs “built in the USA by American workers.”
LSG, in comparing its new LED bulbs to those GE ones “made in China,” says that its new A19 bulb, for example, “has a longer life and retails at approximately half the suggested retail price ($20 vs. $40) of GE’s recently announced, but not available until later this year, Energy Smart A19 bulb.” LSG’s new line up includes A19, PAR38, PAR30, PAR20, MR16, and G25 bulb types “that are all dimmable and will last nearly 20 years.”
LSG said that these new Definity bulbs were tested for “performance and reliability” under the LM-79 process by an independent laboratory approved by the U.S. Department of Energy’s CALiPER program. It believes that its bulbs, pricing in the range of between $20 and $55, will have a payback of one to two years for energy efficiency savings.
