Daylighting Controls & Daylight Savings: Optimizing Natural Light Through the Changing Seasons
Studies have shown that natural lighting has proven to improve workplaces by helping employees be more comfortable and efficient. As…

LEDs (light-emitting diode) lights offer homes and businesses several benefits. The bulbs are energy-efficient, and durable and improve lighting quality. LEDs also offer flexible lighting solutions. K-12 schools also see these and other benefits. Students often improve academically after school’s upgrade to LED lights. It’s a cost-effective solution to lower energy usage costs and boosts student performance.
Before the 1930s, schools used sunlight. Artificial light was not widely available. An open-air movement in the 1930s and 1940s encouraged the addition of open spaces to improve the psychological and physiological well-being of students. It’s the start of schools implementing outdoor activities and physical exercise as part of the curriculum.
After WWII, the focus shifted to other design elements, primarily ventilation, heating, lighting, and acoustics. It’s when fluorescent lighting becomes the standard in most schools. However, studies are showing fluorescent lighting can have adverse effects on students. It’s one of the reasons schools are transitioning to LED fixtures.
Did you know we have an entire blog series on LED vs Other Lamps? No matter what type of lighting your school currently has, we have an in-depth review of your lighting vs LED. You can view the whole series here.
Here’s a look at the benefits of LED lighting in K-12 schools.
Multiple studies show installing LED lighting can improve academic performance. The lights can be set to mimic natural sunlight which improves concentration. Improved focus often leads to a boost in a student’s ability to learn and retain information.
LED lights can be tuned to white or blue light, depending on the time of the day. For example, younger students often have difficulty concentrating in the morning. Adjusting the LED lighting can help regulate natural biological rhythms, making it easier for students to focus.
Researchers are learning that LED lights can improve cognitive skills, reducing student error rates.
Professor Dr. Michael Shulte-Markwork, formerly the director of the Clinic for Psychosomatics in Children and Juveniles at the University Medical Centre Hamburg-Eppendoft conducted a one-year experiment studying the effects of light on students’ learning behavior. Working with 18 teachers and 166 students ranging in age from 8 to 16, he took baseline measurements and results using scientifically proven tests. A control group worked with standard lighting and the test subjects had dynamic lighting. Teachers were allowed to adjust the dynamic lighting to match the activity or time of day.
Teachers choose from four preset lighting controls,
The lighting systems used different color temperatures and light output, allowing for flexibility. Some of the results of the experiment indicate,
K-12 schools are not the only ones studying the effects of lighting. Numerous studies in the healthcare industry show that the use of LED lighting improves patient comfort and enhances staff performance.
Something else for schools with fluorescent lighting to consider is what to do with damaged or broken bulbs. Fluorescents contain mercury and schools must shut down until all traces of the hazardous material are removed from the campus. When an LED bulb breaks, schools only need to worry about broken glass. LEDs are free from hazardous materials.
Improving focus in the classroom is not the only benefit schools see by switching to LED lighting. Energy bills also decrease. LEDs use less energy than other types of lighting. Schools can also recycle LEDs, unlike fluorescent tubes.
According to the U.S. Department of Energy, switching to LEDs can reduce your energy consumption by 75 to 80 percent. By adding controls like times, dimmers, and sensors, schools can further reduce their energy costs.
Schools can further reduce energy costs when it comes to heating and cooling. Fluorescents emit more heat than light, unlike LEDs.
When your school is ready to upgrade to LED lighting, follow these steps to ensure a successful project.
