Codes + Standards

LUX recently published a primer on luminaire ingress protection (IP) ratings. Check it out here.

A proposal that would set lighting requirements for high-rise dwellings in the energy standard published by ASHRAE and the Illuminating Engineering Society (IES) is open for industry comment. Fourteen addenda to ANSI/ASHRAE/IES Standard 90.1-2013,Energy Standard for Buildings Except Low-Rise Residential Buildings, are open for public comment from March 25 until April 24, 2016. Among the [...]

The TALQ Consortium, developing a global standard for interfaces to manage outdoor lighting networks, has made a significant step towards the official rollout of the TALQ Certification Program. During the first TALQ plug test in Valencia, Spain, the specially developed Test Tool – to be used to test outdoor lighting products for TALQ-compliance – was [...]

The ZigBee Alliance, a non-profit association of organizations creating open, global standards that define the Internet of Things (IoT) for use in consumer, commercial and industrial applications, recently announced with the EnOcean Alliance, a leading consortium for battery-less, wireless smart buildings and smart homes, that the two organizations will cooperate on combining the benefits of [...]

CIE, the global lighting organization that maintains the CRI standard, is now studying TM-30: The CIE recognizes that the colour fidelity metrics including the CRI do not assess other important aspects of the colour qualities of light sources, in particular, those related to colour preference. CIE TC 1-91 is developing a Technical Report on this [...]

The National Electrical Manufacturers Association (NEMA) responded to IES TM-30-15 with NEMA LSCR-PP 1-2015 Light Source Color Rendition. The Illuminating Engineering Society (IES) recently published TM-30-15 IES Method for Evaluating Light Source Color Rendition. NEMA has produced a position paper, Light Source Color Rendition, in response to this document. Mark Lien, chair of NEMA Light [...]

I recently had the pleasure of interviewing Mark Lien LC, CLEP, CLMC, HBDP, LEED BD&C, Director of Government and Industry Relations at OSRAM SYLVANIA and chair of NEMA Light Source Section. The topic: IES-TM-30, which proposes a new method of color evaluation, including new metrics to express color fidelity and saturation. I’m happy to share [...]

The Zhaga Consortium, an organization aiming to standardize LED light engines and associated components, has published Book 11 for small LED spotlight modules. Book 11 is a specification that describes circular LED modules with a diameter of 35 mm that are suitable for spotlighting and related applications. A Book 11 module requires a separate LED [...]

The International Commission on Illumination (CIE), which created and maintains the color rendering index (CRI) standard, recently published a position statement on CRI, its limitations, and whether and how to replace it. The complete statement is available here. Notable excerpts: On the limitations of CIE: “With the rapid uptake of LED lighting, which has greater [...]
