The National Electrical Manufacturers Association (NEMA) recently published NEMA 77-2017 Temporal Light Artifacts: Test Methods and Guidance for Acceptance Criteria. Temporal Light Artifacts (TLA) are undesired changes in visual perception induced by a light stimulus whose luminance or spectral distribution fluctuates with time, such as flicker and stroboscopic effect. This new lighting standard makes recommendations [...]

The Light and Health Institute will be held on September 26-27, 2017 at the Lighting Research Center (LRC) in Troy, NY. This two-day, hands-on seminar for industry professionals will cover the latest research as it can be applied, and the knowledge necessary to improve modern living environments with circadian-effective lighting to support human health and [...]

Some amazing long-exposure light art for your Friday. Enjoy!

The Richard Kelly Grant was established by the New York Section of the Illuminating Engineering Society in 1980. Originally conceived as a scholarship program and later opened to young persons working in lighting in North America, the Grant is administered by the New York Section under the auspices of the IES. Cash award(s) are granted [...]

Espen Technology’s Flex DE lamps are AC direct (UL Type B) double-ended LED T8 lamps. They allow AC direct input from both ends for backward compatibility with single-end wiring. They are DLC listed and come in 2’ 9W, 3’ 12W, and 4’ 14W & 18W configurations. These lamps accept universal voltage at both ends (120–277VAC), [...]

Shirley Coyle, President of Cree Canada, recently contributed her thoughts to Lighting Design & Application in response to a request to chime in on the American Medical Association’s recent guidelines for LED outdoor lighting. She points out that basing recommendations on correlated color temperature (CCT) is flawed: On the issue of safety, the most obvious [...]

Earlier this year, the Department of Energy hosted its 14th annual Solid-State Lighting R&D Workshop. Over three full days, 250 attendees participated in sessions covering LED and OLED technology. Presentations from 60 experts addressed the complex science and technology challenges facing SSL today, as well as innovative new ways to improve manufacturing processes, reduce costs [...]

The IEEE recently published an article explaining LiFi, or light-based communication, which is now being commercialized. Check it out here. Some of the comments on the article are also interesting.

The first quarter of the year ended on a positive note for the Architecture Billings Index (ABI). 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 March ABI score was 54.3, up [...]
