The National Electrical Manufacturers Association (NEMA) has formally requested that the Secretary of Energy complete a rulemaking for general service lamps that Congress required in the Energy Independence and Security Act of 2007 (EISA-2007). The Department of Energy (DOE) began the rulemaking in December 2013 and published two rules on January 19, 2017, addressing only [...]

LED area and roadway lighting promises energy and maintenance cost savings, but the longevity of the LED light source presents a hitch. Traditionally, luminaires are cleaned upon relamping. If relamping does not occur, dirt buildup becomes a more important maintenance factor. That being said, it is claimed LED luminaires are less prone to dirt accumulation. [...]

DOE has published the results of a study of the expected contributions to sky glow from converting high-pressure sodium (HPS) street lighting to broader-spectrum (i.e., white light) sources, with specific focus on LEDs, and presents the contributions in a manner relative to HPS baseline conditions. These conditions represent typical conversions in the U.S. and include [...]

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 Although I recently spent a week at the beach, there was no sand, surf, or bathing suit in sight. That’s because I was in Long Beach, CA, at DOE’s 14th annual Solid-State [...]

Focal Point Amica 2 is a new recessed luminaire designed for shallow plenum applications, targeting price sensitive new construction or remodel projects. Amica 2 is the next generation of Amica, featuring a superior angular housing, very high efficacy, and enhanced control features. The luminaire is available in 2×2 and 2×4 sizes with multiple mounting options: [...]

Below is my contribution to the April issue of tED Magazine. Reprinted with permission. Outdoor lighting has proven a key market for LED sources due to their durability, directionality, efficiency, longevity, color and optical control. While metal halide and high-pressure sodium remain predominant in the installed outdoor lighting base, LED has captured a majority of [...]

tED Magazine recently published a lighting supplement that featured a 2017 Lighting Outlook, based on surveys conducted by the magazine and LightNOW of lighting manufacturers, electrical distributors and electrical contractors. The results show a positive outlook for the year among all three market segments (example manufacturer results shown below). Click here to check it out.

The U.S. Department of Energy’s CALiPER program has released a new Snapshot Report on LED industrial luminaires, based on DOE’s Lighting Facts database. Key findings: • The efficacy of LED industrial luminaires is notably higher than what’s typical of their incumbent counterparts. About 23% of the industrial luminaires listed with LED Lighting Facts listed products [...]

My contribution to the April issue of ELECTRICAL CONTRACTOR presents TM-30, the proposed method for evaluating color rendering and saturation, and describes a recent study that suggests saturation is critical to truly evaluating color quality. Specific gamut shapes may be critical to modeling human color preference. The study found that Rf is a good predictor [...]
