My contribution to the July issue of ELECTRICAL CONTRACTOR talks about dimming curves and why they’re important. As dimming becomes more important, electrical contractors may benefit by becoming familiar with dimming curves. The dimming curve defines how dimmers set voltage output in response to control signal input, such as a slider position. Intuitively, it would [...]

Lisa L. Isaacson (NuLEDs) and Michael S. O’Boyle (Philips Lighting) discussed power over Ethernet (PoE) systems at the National Lighting Bureau’s Annual Lighting Forum during a session called “Illuminating the Future, Part One”. Randy Reid (EdisonReport) moderated. According to Isaacson and O’Boyle, PoE differs from conventional DC networks in that the cabling used can carry [...]

Below is a short news article I wrote for tED Magazine on the topic of NALMCO’s new controls certification. Reprinted with permission. The interNational Association of Lighting Management Companies (NALMCO) has launched the Certified Lighting Controls Professional (CLCP) designation. With no prerequisites, the CLCP is open to all professionals in the building, information technology and [...]

PC WORLD recently published an article about the type of visible light communication we don’t want, one that leaks passwords and other data. Here’s how it works. Malware hijacks the blinking lights on a PC, which then transmit data to a drone. The researchers at Ben-Gurion University of the Negev demonstrated how it could be [...]

From LUX: “Hackers harnessing Internet of Things (IoT) devices, including smart lights, have crashed some of the world’s biggest websites including Spotify, PayPal and Twitter. It is no secret, as revenues from LEDs fade, that the lighting industry is placing a big pile of gambling chips on the success of the Internet of Things, but [...]

The interNational Association of Lighting Management Companies (NALMCO) has launched a new lighting controls certification, the Certified Lighting Controls Professional (CLCP). The certification is based on the Education Express curriculum developed by the Lighting Controls Association. The announcement was made at the organization’s annual conference in Dallas, TX. The lighting industry is undergoing massive change [...]

The Lighting Controls Association (LCA) has published a new course to enhance its popular Education Express program: EE303: Tunable-White Lighting. As acting education director of LCA, I was happy to have the opportunity to author this content. LED lighting technology promises many benefits, one of which is practical color output tuning. Popular approaches include full-range, [...]

The Lighting Controls Association (LCA) has published a new course to enhance its popular Education Express program: EE203: Lighting and Commercial Energy Codes, Part 2: ASHRAE/IES 90.1-2013 and IECC 2015. I was happy to have the opportunity to produce this content for LCA. Complying with a Department of Energy mandate, a growing number of states [...]

Philips recently announced a first-of-its-kind, large-scale lighting installation at a major university campus that leverages Power over Ethernet (PoE) as part of the recently opened Watt Family Innovation Center at Clemson University. As a founding innovation partner of the center, Philips implemented a PoE-based indoor lighting system combined with LED lighting to provide flexible work [...]
