This is an update to let you know of the status of the much-anticipated liquid-cooling LEDs from San Jose-based Switch Lighting. SWITCH60, a 60-watt equivalent bulb that produces 800 lumens at 12 watts (clear) or 13.5 watts (frosted), is currently available at 350 participating Batteries Plus stores nationwide. The SWITCH40 and SWITCH 75 will also be available later this month from Batteries Plus.
Today Best Buy entered the consumer LED lighting game in a major way with two Insignia light bulb offerings from Cree. Available exclusively at Best Buy, the 40-watt and 60-watt equivalent bulbs have the shape of a traditional incandescent bulb with omnidirectional lighting and they’re sold for $14 and $17, respectively.
Today Philips announced Hue — “the world’s smartest web-enabled LED home lighting system.” The new LED lighting system is available exclusively from Apple, both online and in stores, starting on October 30, 2012, and requires an iOS or Android app and a home Wi-Fi router. It can handle up to 50 light bulbs, each of which output 600 lumens and use about 8.5 watts of energy.
This is the beginning of our series called Energy-Efficient Windows 101 made possible by Marvin Windows and Doors. For this first article, I want to talk about the various acronyms you might see on a home window label, or in window specification materials, so you’ll know more about what you’re reading. When evaluating energy-efficient window options, Marvin suggests that you understand the basics of the following words and acronyms:
Over the years I’ve tried to fill in our coverage with more substantive, or how-to, information on topics relating to sustainable homes. One topic that I’ve been itching to cover is energy-efficient windows, and I’m happy to announce that Minnesota-based Marvin Windows and Doors has agreed to share their expertise with Jetson Green for a series of articles loosely titled “Energy-Efficient Windows 101.”
