Focal Point’s Theory LED pendant, first introduced as a concept luminaire at LIGHTFAIR in 2008, is now a reality. Designed by Focal Point product designer Graeme Watt, Theory possesses a striking elliptical form that allows the LEDs to be integrated and concealed, illuminating both inside and outside surfaces. Low-voltage power is delivered via the aircraft [...]

I recently produced a special section on LED lighting for the April issue of BUILDING DESIGN + CONSTRUCTION Magazine. Check it out in BD+C’s digital edition here (LF4-LF24, an insert between PP. 42-43).

Click the below video to see how Berndnaut Smilde, a Dutch artist, creates clouds indoors. See the cloud form, interact with light, and disappear.

I recently authored an article for the Lighting Controls Association about a recent Energy Center of Wisconsin study demonstrating that proper commissioning of daylight harvesting lighting controls can lead to higher energy savings. But an even bigger lesson, I believe, can be found in commissioning all automatic lighting control systems. Read it here.

Precision-Paragon [P2] recently published the results of its Energy-Efficient Lighting Industry survey, distributed to more than 4,000 energy efficiency professionals. The survey results show that 77% of survey respondents expect their energy-efficient lighting revenue to grow in 2013. The survey also suggests that automated lighting controls, such as occupancy sensors, are being specified in nearly [...]

OSRAM SYLVANIA’s LUMALUX PLUS XL ECOLOGIC high pressure sodium (HPS) lamp offers a rated life of 80,000 hours, over three times that of standard 24,000-hour HPS lamps. SYLVANIA LUMALUX PLUS XL lamps are the first to combine non-cycling and instant hot restrike features into one lamp and are made in the United States. The non-cycling [...]

The National Academy of Sciences (NAS) has published a report, Assessment of Advanced Solid-State Lighting. The NAS committee reviewed the development and future impacts of SSL, including projections of cost and research and development (R&D) necessary to overcome barriers to widespread adoption. The report recommends: * Continue investments in LED core technology, aimed at increasing [...]

Roundabouts, also known as traffic circles, are increasing in number across the U.S. These intersections generally increase traffic flow while reducing the severity of automobile accidents. However, as relatively new traffic features, modern roundabouts are sometimes described as confusing for drivers. One difference between roundabouts and conventional cross-type intersections is the location of pedestrian crosswalks. [...]

My lighting column in the April 2013 issue of ELECTRICAL CONTRACTOR addresses LED product maintenance. Over the past months, I’ve had the opportunity to work with the IES Maintenance Committee on revising RP36, and conducted extensive interviews with manufacturers and others about maintaining LED products. As you might suspect, they’re not quite maintenance free. Click [...]
