The U.S. Department of Energy’s GATEWAY program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.

I wrote the below news item for the September issue of tED Magazine. Reprinted with permission. High- and low-bay luminaires are common in industrial applications such as warehouses and manufacturing but also certain commercial applications such as big-box stores. “High bay” frequently refers to luminaires mounted at a height over 20 feet, “low bay” up [...]

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 [...]

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 [...]

CSIL recently published the 2017 edition of its report, The Lighting Fixtures Market in the United States. Running about 200 pages, the report covers market size and trend, international trade, distribution channels and reference prices, market segmentation and product characteristics, financial key indicators, sales data, short profiles and market shares of the major local and [...]

Produced by the Department of Energy’s Energy Information Administration (EIA), the 2015 Residential Energy Consumption Survey (RECS) shows growing adoption of energy-efficient lighting in homes. The 2015 RECS shows that a majority of U.S. homes feature more than one type of lamp, primarily a mix of incandescent and CFL. But LED adoption was growing, with [...]

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. [...]

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 [...]
