ARCHITECTURAL LIGHTING recently published an article by Alice Liao, whom I had the pleasure of working with back when I ran the magazine, that describes the importance of luminaire optics in capturing the true light and energy savings potential of the LED light source. Click here to read, “LEDs: Understanding Optical Performance.”

DOE’s Municipal Solid-State Street Lighting Consortium (MSSLC) has released the results of a voluntary web-based inventory survey of public street and area lighting across the U.S., conducted during the latter half of 2013 and intended to improve understanding of the role of public outdoor lighting in national energy use. Results were based on the responses [...]

Architectural Area Lighting’s (AAL) KicK is an aesthetically distinctive site and area lighting luminaire that angles light upwards yet provides full light cutoff. The pedestrian-scale luminaire is targeted to walkway, path and building entrance applications. The design hides the LEDs when viewed from behind. The optical system delivers 12,880 lumens at 99 lumens/W with 0% [...]

The U.S. Department of Energy has released a report on the longer-term performance of an LED lighting system that was installed on the I-35W Bridge in Minneapolis in September 2008 and represents one of the country’s oldest continuously operated exterior LED lighting installations. The report is a welcome addition to the literature on LED lighting, [...]

NEMA’s shipments index for incandescent A-line lamps dropped sharply during 2014Q2, declining 61.2% as the full effect of EISA 2007 lamp efficiency regulations took hold during the first six months of the year. Substitute lamp types such as LED A-line and halogen A-line fared better, posting increases of 35.8% and 9.9% q/q, respectively. Meanwhile, the [...]

Until recently, roadway lighting technologies changed very slowly. Technologies like high pressure sodium and other HID lamps used in cobra head-style fixtures were state-of-the-art for decades. In response, the best practices for roadway lighting design had remained largely unchanged since the 1970s and 1980s. A growing concern for preventing light pollution in the 1990s and [...]

It’s an exciting time to be in the lighting industry. Today, lighting systems can alter spaces without physically changing them, revitalize urban areas, facilitate interaction and community, communicate information, make spaces more interactive, and affect well being. As technology capabilities increase and costs decline, a dramatic range of possibilities offer the opportunity to transform how [...]

Acuity Brands, Inc. recently introduced Winona FORMS LED architectural solutions from Winona Lighting. New traditional, transitional and contemporary styles are offered in a variety of complementary architectural shapes across the brand’s pendant, ceiling-mount and wall sconce portfolio. Winona has engineered a unique, patent-pending Form Analogous (FA) Optical System(tm) to fully optimize the potential of LED [...]

The Open University (UK), in honor of the 2014 Nobel Prize in Physics being awarded to three scientists for developing the blue LED, produced the below infographic, which I’m happy to share with you below. Click to enlarge in a new window on your browser.
