DOE: Why Tunable? A Look at Schools Using Tunable Lighting

William Attardi on June 27, 2025

LED technology enables dynamic lighting solutions that can adapt to the occupants, tasks, and daylight in a space. Tunable lighting systems can alter the intensity and/or spectral characteristics (color) of the source. As more schools across the U.S. transition from fluorescent to LED technology, many are likely to consider tunable lighting. This case study aims to help decision-makers by looking at past and current tunable lighting projects.

    • Why did schools choose tunable lighting?
    • What features were selected?
    • How was tunable lighting implemented?
    • What was the teacher feedback?

This case study examines tunable lighting installations at eight school districts across the United States. Why Tunable? A Look at Schools Using Tunable Lighting

 

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

William Attardi on January 21, 2025

Parts 1 and 2 of this series discussed the sluggish adoption of LED technology in schools and the dim prospects for fluorescent lighting. This final part addresses the LED choices school facility personnel are considering and the new tradeoffs they face. Based on PNNL’s conversations with schools, the change to LEDs is underway. Upgrading lighting can reduce energy consumption and operating costs and refresh the look and feel of the school. Fluorescent lighting has served schools for a long time. What does maintaining an LED system look like for the next 30 or 40 years? While TLEDs seem like an easy solution today, relying on fluorescent luminaires and other components will become more challenging in the future. Compare the up front and ongoing costs for each LED option and consider developing a “standard” lighting solution that can be repeated over time, space by space, or school by school.

The First Army-Navy Game – Cadets and midshipmen played their first football game Nov. 29, 1890 on “The Plain” at West Point. Navy had been playing organized football since 1879 and defeated the newly established Army team, 24-0. The historic event would become one of the most celebrated traditions in American college sports: the Army-Navy football game. This was not just a mere football match; it was the birth of a rivalry steeped in pride, honor, and the spirit of friendly competition between the United States Military Academy (USMA) at West Point and the United States Naval Academy (USNA) at Annapolis. The Army-Navy game is more than just a sporting event; it is a celebration of American military service, a showcase of athletic prowess, and a testament to the enduring spirit of rivalry and respect. It’s not just about who wins or loses; it’s about tradition, honor, and the unbreakable bond between two esteemed military institutions.
