Energy Efficiency News

April 22nd, 2012 by  

 
Aside from our own energy efficiency stories from the past week, here are a few more from around:

Lighting

  • Cree has introduced the XSP Series LED Street Light. This new street light series is “the most affordable and efficient Cree® LED street light designed to speed payback to municipalities. Using nearly 50 percent less energy and designed to last over three times longer than wasteful, traditional high-pressure sodium street lighting, the XSP Series can double the lumens per dollar compared to previous generations of Cree LED street lights and is the ideal choice for cities and municipalities looking to save money and resources.”
  • Cree has also developed the first “254 lumen-per-watt white R&D power LED” — not my field of expertise, but seems noteworthy.
  • Lighting Science Group has announced “the production launch of a revolutionary high output 8-watt LED MR16 bulb that is a direct replacement for traditional MR16 50-watt halogen bulbs. Suited to a variety of applications that require directional lighting—such as track lighting, recessed ceiling lights, desk lamps, pendant fixtures and retail display lighting—the DEFINITY™ MR16 HO LED bulb will be the first of its kind introduced to the marketplace, and considered the best of its breed when evaluated by metrics of efficiency, lumen output and form factor.” (Picture of bulb below.)

Energy Management

  • Nest, which has been sued by Honeywell on several counts of patent infringement, has “countered in court what it believes are meritless allegations by Honeywell of patent infringement in relation to the innovative Nest® Learning Thermostat™.” The home thermostat company has also brought on former Apple Chief Intellectual Property Officer Richard “Chip” Lutton, Jr. as vice president and general counsel.
