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.
NEMA Publishes NEMA LSD 73-2015 Energy Savings with Fluorescent and LED Dimming
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 […]
Jim Brodrick on the Connected Lighting Trend
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 Finds Its Applications
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 […]

Interview with Philips Lighting’s Brian Bernstein on LED Luminaire-Integrated Controls
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. […]
Market Research Suggests High Degree of Confidence with LED Lighting and Controls
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 […]
Smart City Lighting
LEDs Magazine recently published an article by Jurgen Hase, VP of machine-to-machine competence at the Deutsche Telekom, in which Hase describes a trend among cities to adopt networked lighting control. These lighting control systems allow remote control and operation of streetlighting systems for significant benefits–not only energy savings and improved maintenance of the lighting, but […]
Jim Brodrick on Dimming LEDs with Phase-Cut Dimmers
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 You may recall that last year, DOE’s GATEWAY program released a report entitled Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success, which was created in response to issues raised […]
DOE Publishes Revised Report on Dimming LEDs with Phase-Cut Dimmers
The U.S. Department of Energy has revised its October 2013 report, Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success, to include updated information about the installation of LED lighting and controls at the Burden Museum in Troy, NY, a GATEWAY project that was still in construction when the original report was published.
