DLC Releases Updated Networked Lighting Controls Technical Requirements

William Attardi on June 29, 2026

Reinforcing the role of lighting controls as the foundation for deeper energy savings through connected commercial lighting, the DesignLights Consortium (DLC) today finalized updates to its Networked Lighting Controls (NLC) Technical Requirements. NLC systems that apply for and meet the requirements are listed on the NLC Qualified Products List (NLC QPL), which is used by industry stakeholders to select and verify high-quality NLC systems. The NLC QPL is the only list of its kind that provides extensive, verified information on interoperability, cybersecurity, and data access for each system. Taking effect August 3, NLC V5.2 reflects feedback received from DLC members and lighting industry stakeholders during a public comment period that followed release of the first draft of the policy in March. For additional context, please see the DLC Blog. The DLC will host two webinars to provide more information on NLC V5.2. The NLC V5.2 Final Release Webinar highlighting key details of the technical requirements will take place on July 8 at 3 PM ET – register here. A second webinar at 1 PM ET on Aug. 3, NLC V5.2 Application Guidance, will focus on implementation of the new policy – register here.

BriteSwitch – Commercial Lighting Controls: A Growing Rebate Opportunity

William Attardi on April 22, 2026

Traditional controls fit well within prescriptive rebate programs because they are relatively easy to define, verify, and explain. For decades, programs have offered incentives for adding components such as fixture-mounted occupancy sensors, and these incentives are not going away. In fact, incentives for traditional lighting controls increased by 12–20% this year, depending on the measure. In addition to traditional controls, more advanced lighting control systems have gained prominence in recent years. These systems are typically more intelligent, allowing devices to communicate and respond dynamically to changing conditions. Rebates for advanced systems like NLC and LLLC have historically been more complex. While most programs provide incentives for these systems, the structure varies widely. Some offer incentives through custom programs based on projected kWh savings. Others provide per-fixture adders or separate line items based on control type. RebatePro for Lighting by BriteSwitch is designed to help contractors and distributors identify the best rebate opportunities, estimate incentives for specific projects, and stay current as programs continue to evolve across the US and Canada.

Memo: Clarifications to the NLC 2020 Report – 2025 update

William Attardi on February 22, 2025

 “Energy Savings from Networked Lighting Control (NLC) Systems With and Without LLLC”  Key updates include refined clarification of the definition of luminaire-level lighting controls (LLLC) used in the report, elaborated explanations on several important aspects of the control savings factors (CSFs), and distinguishing the calculation methodology between high-end trim savings and other control strategies (occupancy sensing and daylight harvesting). The memo emphasizes that the documented CSFs reflect average savings across a diverse set of projects, where optimal programming varied, and highlights considerations for small sample bias in evaluations. Building-specific CSFs and their limitations are explained, and the memo differentiates findings from a related redesign study to avoid misinterpretation. Lastly, an updated executive summary and errata sheet correct clerical errors, reaffirming that NLC systems with LLLC offer higher energy savings potential but encouraging ongoing updates as technology and datasets evolve.

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.
