Below is my contribution to the September issue of tED Magazine, on the topic of residential lighting trends. Reprinted with permission. In 2016, residential put-in-place construction spending increased to about $467 billion, according to the U.S. Commerce Department. This marked a fifth year of double-digit growth since the 2008 recession. The National Association of Home [...]

The Department of Energy’s GATEWAY program recently published a new report on a project prominently featuring OLED lighting at the Rochester, NY offices of DeJoy, Knauf & Blood, LLP, an accounting firm. One of the firm’s founding partners, David DeJoy, is also co-founder and CEO of OLEDWorks, the only US-based OLED manufacturer. Among the key [...]

For the sixth consecutive month, architecture firms reported increasing demand for design services as reflected in the July Architecture Billings Index (ABI). As a leading economic indicator of construction activity, the ABI reflects the approximate 9- to 12-month lead time between architecture billings and construction spending. The American Institute of Architects (AIA) reported the July [...]

The Million Lamp Challenge has officially been launched by the University of California system in consultation with the California State Department of General Services. The groups have issued their purchasing standards to encourage the purchase and installation of high-quality LED lamps in their buildings: • UC System Purchasing Standard • DGS Purchasing Standard The purchasing [...]

Designed to fit shallow plenums above ceilings in residential and light commercial settings, WAC Lighting’s Lighting for Tomorrow Award-winning Aether IC Rated family from WAC Lighting is engineered with a low-profile 3.5-inch LED housing. Fitting into ceilings with thicknesses that range from just 0.5 to 1.5 inches, the luminaire operates as a down light for [...]

In a recent issue of LEDs Magazine, Dr. Nadarajah Narendran, Director of Research at the Lighting Research Center, discussed LRC research focused on LED system reliability that revealed that some LED products available on the commercial market can fail much sooner in some applications than manufacturers’ lamp life specifications would suggest. The studies found that [...]

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 [...]

Norma Frank, CLMC recently contributed a maintenance column to LD+A that talks about LED streetlighting maintenance. Traditionally, HID luminaires are cleaned when they are relamped, limiting light loss imposed by luminaire dirt depreciation (LDD). As stated above, LED luminaires promise much longer service life. They may present a different failure mode based on output rather [...]
