Craig DiLouie, LC recently had the opportunity to interview Audwin Cash, VP Acuity Controls Solutions, Acuity Brands Lighting, Inc. The topic: controlling LED lighting. DiLouie: How are LED sources different from traditional sources in terms of controllability and behavior while controlled? Cash: LED sources are the first economically viable solid state light source. LEDs, paired […]
The U.S. Department of Energy’s inaugural Connected Lighting Systems Meeting, held November 16 in Portland, OR, saw more than 260 experts from the lighting, semiconductor, and IT industries gather to share perspectives and lay the groundwork for government/industry collaboration on the convergence of intelligent controllable light sources, communication networks, sensors, and data exchange in future […]
Alumage Advisors has released its latest LED Smart Lighting Report, including a free version for end-users, highlighting 40 product features of interest for 1,000 commercial and industrial (C&I) luminaires worldwide. “Since introducing our first reports in 2013, we added a smart lighting focus, as 77% of the products we track are dimmable, 59% offer motion […]
In an article recently published by LEDs Magazine, Lutron Electronics’ Roland Ledyard explains that while 0-10V dimming is a standard driver feature, every technology decision has a cost. He makes an argument that digitally addressable drivers are often a more economical decision. Click here to read the article.
The National Electrical Manufacturers Association (NEMA) published NEMA LSD 73-2015, Energy Savings with Fluorescent and LED Dimming. This new white paper describes the signal path from the user control input through the control wiring, ballast or driver, and lamp or LED module. It also explains factors that affect energy consumption and savings, efficacy and user […]
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy As we mentioned in these Postings a few weeks ago, the biggest takeaway from this year’s LIGHTFAIR® International was the prevalence of connected products, and the fact that sensors and controls seemed […]
Visible light communication (VLC) is a particularly exciting technology in an industry that is already going through exciting technological change. This technology, popularly used in applications such as fiber-optics, now shows promise for general lighting due to the advent of LED lighting. The potential is to create spaces that actively communicate with users. What is […]

Craig DiLouie, LC recently interviewed Brian Bernstein, Global Head of Indoor Lighting Systems, Philips Lighting, about LED luminaire-integrated lighting controls. DiLouie: How would you characterize demand for LED luminaires with integrated controls? Bernstein: The demand for LED luminaires with integrated controls is increasing, driven by improving LED source performance, regulatory compliance requirements, and sustainability concerns. […]
Given current adoption of commercial building energy codes, conventional wisdom indicates that LED lighting is frequently specified with automatic lighting controls. However, there is little public data available concerning market penetration of LED lighting, how often it is specified as controllable and with lighting controls, owner preferences, and how satisfied specifiers and installers are with […]
