Deep Dive: Fundamentals of Commercial Lighting Controls by Craig DiLouie

A good lighting design is incomplete without a good controls design. Lighting controls determine when the lights turn On, when they turn Off, how bright they are, which luminaires respond, the response to daylight or occupancy, and how occupants interact with the lighting in the space. Controls may be simple or highly sophisticated, but every control system can be defined by the same fundamentals: inputs, outputs, programming, communication, and sequence of operation. This content is written for those who already have a working knowledge of lighting and now need a foundation in lighting controls. Lighting controls may be as simple as a wall switch or as advanced as a networked system……… Lighting professionals focus on providing good lighting design that supports visibility, comfort, safety, appearance, and energy performance. Lighting controls determine how the lighting behaves. A lighting system without appropriate controls may provide the right amount of light, but not necessarily at the right time, for the right task, or in the way occupants prefer. Controls facilitate the lighting system response to people, schedules, daylight, energy goals, code requirements, and changes within the space. .

Combining the Dots by Craig DiLouie

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

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

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.

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

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

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

It’s Back to School – How Some of Our Most Acknowledged Universities Got Their Name – Who were the true visionaries who would donate half of their estate to sculpting the minds of the future. These stories are monuments to history and culture. Let’s take a stroll through academia’s memory lane and uncover the origins of these storied university names!

  1. Ah, Harvard! The Ivy League giant was once a small college in the Massachusetts Bay Colony settlement called New Towne. But where did “Harvard” come from? Enter John Harvard, a clergyman who, in 1638, decided to bequeath half his estate and his library (a whopping 400 books!) to the fledgling college. Grateful for this generous gift, they promptly named the institution after him.
  2. A gem of New Haven, Connecticut, Yale is another Ivy League powerhouse known for its prestigious law and drama schools. It owes its name to Elihu Yale, a wealthy merchant who, in 1718, donated a modest shipment of goods (including portraits, books, and textiles) to a struggling collegiate school. Those goods were auctioned off, raising a much-needed £562 –a small fortune at the time.
  3. Dartmouth is renowned for its beautiful rural setting, nestled in the picturesque town of Hanover, New Hampshire. It was named after the Earl of Dartmouth, William Legge, a British nobleman who supported the college’s founding –despite never actually setting foot in America!
  4. Brown, this Rhode Island Ivy University, known for its open curriculum and emphasis on student choice, was founded with a mouthful of a name – the College in the English Colony of Rhode Island and Providence Plantations. It was renamed in 1704 for Nicholas Brown, Jr., a prominent merchant whose family donated generously to the school.
  5. Perched atop a hill overlooking Ithaca, New York, Cornell is celebrated for its diverse academic programs and its stunning natural surroundings. Founded by Ezra Cornell and Andrew Dickson White, this university was unique for its commitment to practical education, allowing students the freedom to choose their own course of study. It was a revolutionary notion at the time, which would guide a curricular reform across the country.
  6. Located in the heart of Silicon Valley, Stanford is renowned for its entrepreneurial spirit and its close ties to the tech industry. But this California powerhouse has a touching origin story. Leland Stanford, Jr., the founder’s son, tragically died young from typhoid fever. His father Leland Sr., railroad magnate and former state governor, and his mother Jane, founded the university in his memory, ensuring his legacy lived on through the pursuit of knowledge.
  7. This North Carolina research giant, known for its strong medical and law schools, underwent a bit of a name change in its history. Originally called Trinity College, it was renamed Duke University in 1924 after James Buchanan Duke, a tobacco and electric power industrialist who founded the American Tobacco Company. He established The Duke Endowment, to which he donated throughout his life and left half his estate after his death.
  8. Nestled in Nashville, Tennessee, Vanderbilt is a renowned research university with a vibrant campus life. It owes its name to “The Commodore,” Cornelius Vanderbilt, a shipping and railroad magnate, who provided the initial gift to establish the university.
  9. Texas businessman William Marsh Rice provided the initial funding for this Houston university, but did not live to see its opening. He was murdered by his valet as he slept, in a plot to forge the man’s will. Despite the unfortunate circumstances, Rice University flourished through the years, becoming an institution known for its strong engineering and science programs.
