The DLC recently released the final version of SSL Technical Requirements Version 4.4. This Technical Requirements update consists of new policies that will allow high performance, energy-efficient horticultural lighting products, DC and PoE products, and field-adjustable light output products to be qualified and listed on the DLC Qualified Products Lists.

Following the completion of a recent investigation of LED street lighting’s impact on sky glow, researchers at Pacific Northwest National Laboratory developed a simplified method for comparing contributions to sky glow among lighting products. On November 8, PNNL’s Bruce Kinzey will describe and demonstrate use of the comparison tool in an hour-long webinar.

The major technological shift to the LED light source has had a major impact on the outdoor stationary lighting market. In its latest solid-state lighting energy savings forecast, the U.S. Department of Energy (DOE) continued to recognize area and roadway lighting market as leading in LED adoption. In this market, DOE estimated 21 percent LED penetration in the installed base in 2015, projecting 91 percent by 2025.

I recently had the opportunity to interview Robert Karlicek, Jr., Ph.D., professor and director, Center for Lighting Enabled Systems and Applications (LESA), Rensselaer Polytechnic Institute. The topic? The future for lighting and the Internet of Things.

I recently had the opportunity to interview Mark Lien, LC, HBDP, CLMC, CLEP, LEED BD&C, Industry Relations Manager, Illuminating Engineering Society, about where things stand right now and possibly in the future for the Internet of Things. (Mark was speaking for himself, not the IES.) The responses helped inform an article I wrote about the IoT for the December 2018 issue of ELECTRICAL CONTRACTOR.

In May 2018, the Lighting Research Center (LRC) released a cautionary report evaluating potential energy savings for LED horticultural lighting. The LRC found that energy savings is possible with LED, but one should evaluate products based on application efficiency rather than simple luminaire efficacy. In short, rather than generalizing about energy efficiency, the lesson seems to be that some LED products save energy compared to some traditional products, depending on the product and the application.

Over the past month, I had an interesting conversation with some big thinkers in the lighting industry about lighting and the Internet of Things. Here’s what they had to say.

With continuous illumination, integrated controls, multiple lens options and single or row mounting, Columbia Lighting’s MultiPurpose Linear is adaptable to numerous applications.

Lumileds’ Matrix Platform light engines use Integrated Light Guide Technology to provide non-pixelated illumination for visual comfort and the flexibility to select tailored light distribution patterns in the design of indoor and outdoor luminaires.
