Fast Company ​– The United States generates more energy than any other country in the world -- and wastes more than half of it. Efficiency, it turns out, can be a rich resource. Those riches are being exploited by a kind of alchemy that combines science with business. Efficient technologies, from sensor-equipped LED lighting to smart electric meters, are flowing at a brisk pace out of labs, attracting capital from Goldman Sachs and Silicon Valley VCs, and support from the likes of Walmart, Chevron, Samsung, and California's major utilities.

Macworld ​product review – Full Spectrum Solutions' Berkeley Lamp II provides provides both downward-focused task lighting and upward-facing ambient lighting with two independent, dimmable fluorescent bulbs. The energy-efficient office lighting solution is also designed to prevent eyestrain and glare. 

New York Times ​– Irritation seems to be rising as more consumers try compact fluorescent lamps which now occupy 11 percent of the nation's eligible sockets, with 330 million lamps sold every year. Consumers are posting vociferous complaints on the Internet after trying the lamps and finding them lacking. In California, where CFLs have been heavily encouraged, utilities have concluded that they will not be able to persuade a majority of consumers to switch until compact fluorescents get better. That is prompting them to develop specifications for a better lamp.

LD+A ​– California Lighting Technology Center (CLTC) has continued research over the past year to develop and commercialize a next-generation daylight harvesting system with automatic commissioning and increased reliability through the use of two photo sensors. CLTC is working with Wal-Mart to demonstrate the product protytype in a retail store and with Watt Stopper/Legrand to commercialize the system.

LD+A – Daylight harvesting is a great strategy to save energy, focusing on partially or completely reducing electric lighting when daylight is available in commercial and industrial buildings. The objective of this article is to offer a closer view of the main issues and potential resolutions in photo senor-based daylight harvesting controls.
