The U.S. Department of Energy (DOE) has published a technical feasibility assessment of replacing existing high-pressure sodium and low-pressure sodium roadway lighting on San Francisco’s Golden Gate Bridge, conducted through the agency’s GATEWAY demonstration program. The goal was to identify solutions which would reduce maintenance and energy use without compromising the quantity or quality of [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy One of the panel discussions generating buzz at DOE’s tenth annual SSL R&D Workshop, held a few weeks ago in Long Beach, CA, was the one that focused on light spectrum and color perception. As [...]

Venture Lighting International, a manufacturer of metal halide lighting systems, recently announced that Harvard Engineering, a manufacturer of LED drivers and control products for the lighting industry, has signed a sole agreement with Venture. The agreement, which is for the distribution and sale of Harvard’s LeafNut solution in the USA and Canada, cements a longstanding [...]

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 [...]
