An article I wrote for tED Magazine. Reprinted with permission. In the construction of some facilities, a skeletal framework is used, which forms an interior subspace called a bay. The Illuminating Engineering Society categorizes these bay spaces as either high-bay (>25 ft. off the floor) or low-bay (15-20 ft. These high-ceiling interior spaces are common [...]

Researchers at Oregon State University have claimed advances in quantum dot technology may lead to LED lighting that generates better light quality with less toxic materials and low-cost manufacturing. Lightingindustry.einnews.com has the story here.

Researchers at Dartmouth College have come up with a method of controlling all lights in a home with simple hand movements. Called LiSense, it uses visible light communication. BizLED has the story. Check it out here.

Waldmann Lighting’s ViVAA offers flexibility and minimalist design for interior spaces, notably medical facilities. Depending on ceiling height and lighting preference, one can choose the size, pendant length and color temperature for the luminaire. The balanced shade is finished with a canopy cover and light ring made of polished stainless steel. The luminaire is available [...]

The U.S. Department of Energy has released a report on a GATEWAY demonstration, in which maintenance and energy costs were significantly reduced while retaining the quality of light when LED modules replaced 87 halogen lamps in existing wall washers at the University of Maryland’s Clarice Smith Performing Arts Center. The project began with mockups in [...]

The Architecture Billings Index (ABI) slipped in August after showing mostly healthy business conditions so far this year. As a leading economic indicator of construction activity, the ABI reflects the approximate 9- to 12-month lead time between architecture billings and construction spending. The American Institute of Architects (AIA) reported the August ABI score was 49.1, [...]

Demand for lighting equipment, as measured by NEMA’s Lighting Systems Shipments Index, increased by 2.2% year-over-year (y/y) and by 0.4% quarter-to-quarter during the second quarter of 2015. The increase was driven by emergency lighting and luminaires, which gained ground on a year-over-year basis, while the ballast and lamp–large and miniature–components offset these gains with year-over-year [...]

The color quality of light sources is critical in a broad range of applications, from making colors pop in retail merchandise to promoting social interaction by properly rendering skin tones. To evaluate, predict and discuss color quality, the industry relies on two metrics, correlated color temperature (CCT) and the color rendering index (CRI). Varying these [...]

Hubbell Lighting’ Alera Lighting has launched two new linear lighting solutions—the Plank 7” LED (LP7) and the Curv Radial Lens LED, a new addition to the Curv Radial family. The Plank 7” LED fixture has a classic rectangular form that is easily integrated into many different design styles. The product can be used for uplight, [...]
