Today Lighting Science Group unveiled a new 60-watt replacement LED bulb that “meets or exceeds all of the criteria for the L Prize,” according to CTO Fred Maxik. If you’re not familiar with the competition, in order to win, the lamp must run better than 90 watts per lumen, produce more than 900 lumens, use less than 10 watts, last more than 25,000 hours, have more than a 90 color rendering index, and have a color between 2700-3000 K.
Some folks are stockpiling light bulbs in anticipation of the future phase-out of standard incandescents, according to USA Today. It seems hoarders are doing it for one or two reasons: cost and/or lighting concerns. But these shouldn’t be concerns. With a little bit of math (initial cost + operating cost) and an understanding of basic lighting terms (lumen, watt, color accuracy, color temperature), I think the switch is a no-brainer. So here’s a five-step program for the hoarder:
In my experience, it seems most people compare appliance models based on cost, appearance, and brand. Some individuals consult the yellow-and-black EnergyGuide label for estimated operating cost and energy use information. Others research models online through the Energy Star products database.
But there’s a new resource for locating the most energy efficient products on the market: Top Ten USA.
Cree, Inc., manufacturer of the popular LR6 LED downlight, just announced a new light bulb. The company unveiled “the brightest, most-efficient, LED-based A-lamp that can meet Energy Star performance requirements for a 60-watt standard LED replacement bulb.” Cree attributes the bulb’s performance to TrueWhite technology and a patented remote-phosphor technology.
Keep an eye out for the next acronym in energy-efficient lighting: ESL, or Electron Stimulated Luminescence. ESLs use “accelerated electrons to stimulate phosphor to create light, making the surface of the bulb ‘glow,’” according to Vu1 Corporation, a maker of ESLs. The technology is being touted for producing light that’s similar to an incandescent bulb but about 70% more energy-efficient.
