A 2016 study at the London School of Economics and Political Science proposes that the way urban spaces are lighted reinforces inequality by providing visual cues to class segregation. Check out this video to learn more.

CLTC recently collaborated with the Emerging Technologies group at Pacific Gas & Electric Company to evaluate linear LED lamps in a variety of luminaire applications, as well as identify cross-compatibility issues of select products.

The increasing popularity of LED technology has raised concerns about retinal damage via a mechanism known as blue-light hazard. Research conducted by the Lighting Research Center demonstrated in a majority of cases LED lighting does not present a greater risk of blue-light hazard than traditional sources such as incandescent.

Wireless features, automated lighting controls, and home automation are becoming more popular in residential projects; the most popular home products demonstrate energy management features. These are just some of the findings from The American Institute of Architects’ (AIA) Home Design Trends Survey covering activity during the second quarter of 2017 that focused on emerging home features, systems and technologies.

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 [...]
