Combining the Dots by Craig DiLouie

William Attardi on June 26, 2026

Integration of lighting control devices and HVAC systems can reduce HVAC energy consumption by up to 20%–30%. This has made it a new front in the ongoing battle to maximize energy savings in commercial buildings as demand for electric power continues to increase with strong growth in infrastructure. While integration traditionally occurred using a building automation system (BAS) or on/off contact-closure interface, the introduction of Bluetooth NLC smart thermostats, interoperable with Bluetooth NLC sensors, promises to simplify integration and expand opportunities to save energy.

2026 Commercial Lighting Rebate Outlook by Craig DiLouie

William Attardi on April 17, 2026

The commercial lighting rebate outlook is strong for 2026, with widely available rebates covering all popular categories of LED lighting and lighting controls, including networked lighting controls. Overall, 2026 marks a year of evolution for programs as they adapt to declining lighting energy savings due to LED market saturation. Average rebate amounts per LED product significantly increased, particularly for higher-energy-saving products. Some programs are shifting from incentivizing products to energy savings. More programs recognizing LED-to-LED upgrades were introduced. On the lighting controls side, average rebate dollars per installed solution generally increased in 2026. As AI infrastructure/data centers and meta projects continue to come online, rising demand for electric power is leading to cost increases. This article evaluates the 2026 commercial lighting rebate outlook based on data provided by BriteSwitch’s RebatePro for Lighting North America database, examines opportunities for LED lighting and lighting controls, and offers insights into how rebate programs are evolving as LED adoption increases. 2026 Commercial Lighting Rebate Outlook

Seeking Standardization: Open Systems Are Becoming More Relevant by Craig DiLouie

William Attardi on March 13, 2026

As lighting systems evolve from simple illumination devices into connected infrastructure, the industry is placing more emphasis on open, interoperable standards. While many control platforms still rely on proprietary hardware and software, open standards are becoming increasingly relevant. A significant player in standards is Zhaga-D4i (zD4i). It combines a standardized plug-in interface for sensors and communication modules with a common digital language for data exchange. For electrical contractors, this framework can simplify installation, improve upgradability and create new opportunities for offering connected lighting solutions. To address this, Zhaga introduced Book 18 in 2018. Now in its fourth edition (released in 2025), Book 18 defines how a smart node physically attaches to an outdoor LED luminaire, receives power and exchanges digital information with the driver. In effect, Book 18 serves as the socket standard for modern connected outdoor lighting. Around the same time, the DALI Alliance expanded its DALI-2 standard to better support internet of things (IoT) and luminaire-level control. With Zhaga’s Book 18 managing the physical and electrical interface and the DALI Alliance’s D4i managing the digital handshake, the two organizations partnered to create the zD4i product certification.

NEMA Academy to Reshape Industry Education by Craig DiLouie

William Attardi on April 12, 2025

For 25 years, the Lighting Controls Association, a council of the National Electrical Manufacturers Association (NEMA), has educated the building industry about lighting control technology and application, notably through its Education Express courses. The organization is proud to announce that starting May 1, 2025, the Education Express curriculum will be incorporated into a new learning management system, NEMA Academy. The new platform will feature an improved website, a comprehensive learning platform, and access to a broad and growing curriculum covering lighting controls in addition to other topics, from lighting to safety to emergency preparedness.

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

TRAINING: How to Design a Lighting Control System by C. Webster Marsh and Craig DiLouie

William Attardi on December 31, 2024

Based on EE105: Lighting Control System Design, a new course in the Lighting Controls Association’s Education Express program provides detailed information about designing an effective lighting control solution. In Part 1 of this Lighting Controls System Design series, we learned about key documentation including the Content Intent Narrative (CIN), Sequence of Operations (SOO), and Owner Project Requirements (OPR). The next step in design development in Part 2, is to turn these requirements and conceptual design into a realized design. In Part 3 of this series on how to design a lighting control system, we will discuss installation and post-occupancy. You will learn about bidding, responding to questions from installers, reviewing submittals and defending your design, following-through with the installation of the equipment, functional testing, training essential staff, and ultimately ensuring the owner is satisfied. How to Design a Lighting Control System

Remembering the Solemn Purpose of Memorial Day

Memorial Day is a federal holiday in the United States observed on the last Monday in May to honor and mourn U.S. military personnel who died while serving in the armed forces. The holiday traces its roots to the years immediately following the American Civil War (1861–1865), which caused massive casualties—roughly 620,000 soldiers dead, about 2% of the U.S. population at the time. Communities across the North and South began spontaneously decorating the graves of fallen soldiers with flowers, wreaths, and flags, a practice that gave rise to the original name: Decoration Day. On May 5, 1868, Major General John A. Logan, commander-in-chief of the Grand Army of the Republic (GAR)—a powerful Union veterans’ organization—issued General Order No. 11. This proclaimed May 30, 1868, as a nationwide “Decoration Day” to honor those who died in the Civil War. After World War I, the holiday expanded to honor all American service members who died in any war, not just the Civil War.  In 1968, Congress passed the Uniform Monday Holiday Act to create more three-day weekends for federal employees. This moved Memorial Day to the last Monday in May, effective in 1971, when it was also officially named “Memorial Day.” As one 1868 quote put it: “That Nation which respects and honors its dead, shall ever be respected and honored itself.”
