Lighting Revolution in Two Graphs: LED Distribution In Residential And Commercial Applications by Craig DiLouie

William Attardi on January 15, 2025

As the LED revolution achieves increasing adoption, a recent report by the Department of Energy illuminates the growth. Published in April 2024, the “2020 U.S. Lighting Market Characterization” https://tinyurl.com/3fczwe9s estimates technology distribution among the U.S. installed base of units (lamps/luminaires), along with energy consumption. Residential sector: Let’s start with the residential lighting sector, where an estimated 6.5 billion units are installed, accounting for 80% of lighting installations. LED was the most popular light source in 2020 with 3.1 billion units installed or 48% of the total, nearly 50% less energy than in 2015.  Commercial buildings: In the commercial building sector, with its estimated 1.6 billion installed units, we see a similarly striking snapshot of LED earning virtual parity with other light sources. In 2020, LED reached an overall share of 48% of the installed base and a rough parity with fluorescent, nearly 30% less energy than 2015 and 57% less than 2001. Again, LED adoption is today the majority light source in commercial buildings.  Lighting Revolution in Two Graphs: LED distribution in residential and commercial applications – Electrical Contractor Magazine

The Lagging Transition to LEDs in Schools – Part 1 of 3 by Jessica Kelly, Andrea Wilkerson, Dan Blitzer

William Attardi on November 26, 2024

This article series looks at the current situation from the perspective of school facility personnel. Part 1 covers the transition to LED technology. Part 2 will identify changes coming to the lighting market, and Part 3 will offer thoughts for practical paths forward for LED systems in schools. Although commercial LED lamps and luminaires have been available for more than a decade, educational facilities have been slow to adopt LED technology. As of 2020, 78% of the lighting in U.S. educational buildings was still fluorescent, according to the most recent estimates from the U.S. Department of Energy (DOE) Solid-State Lighting program in the “2020 U.S. Lighting Market Characterization” report. The general feeling of, “We have fluorescent, we’re fine,” may change as the situation evolves. Stay tuned for Part 2 of this series where we discuss these upcoming changes to the lighting market regarding fluorescent availability and utility rebates.

Pepper Production Trials Entering a Fourth Year

William Attardi on November 21, 2024

Signify and the University of British Columbia has announced that their pepper production trial is now entering its fourth year. This trial, which focuses on optimizing dynamic lighting conditions, has delivered insights into how pepper plants respond to artificial lighting throughout the year. 2025 will mark the culmination of this extensive research project. The final results will be presented in a comprehensive whitepaper, which will detail the outcomes of this trial and combine insights from all other pepper trials conducted around the world. By synthesizing this knowledge, Signify aims to provide growers with a definitive guide to optimizing pepper production using LED lighting, ensuring that they can continue to improve yields and quality well into the future.

Key Themes of Washington’s Farewell Address 

Crafted with the assistance of his close advisors, including Alexander Hamilton and James Madison, President George Washington’s Farewell Address was intended to offer guidance and warnings to the American people as they faced the challenges of the future. Among the most significant themes were:

  1. Neutrality in Foreign Affairs – advising that the United States should avoid becoming involved in the conflicts and political machinations of foreign powers. He argued that such alliances could lead to unnecessary entanglements and could jeopardize American interests and independence.
  2. The Dangers of Political Parties – Washington expressed concern that political factions could lead to divisions within the country and weaken the unity of the nation. He believed that political parties could become sources of discord and could prioritize their own interests over the common good. He encouraged Americans to work together for the benefit of the nation as a whole.
  3. The Importance of National Unity – He emphasized that the strength of the United States depended on the unity of its people and the coherence of its government. Washington urged Americans to set aside regional and political differences and to work together to build a strong and prosperous nation. Source: Day in History
