The quality of lighting in classrooms is an important factor in supporting students’ cognitive development and academic performance.
The purpose of this research was to demonstrate the seasonal differences between the groups tested and to highlight the importance of high quality, full-spectrum lighting that mimics the sun, especially in winter when natural sunlight is scarce. Students in the experimental group with full-spectrum lighting achieved up to 83% of the maximum test scores for attention, concentration and work rate in winter compared to less than 30% for the control group with normal lighting.
Students in the bio-optimised lighting class achieved above-average results in secondary school entrance exams
Most of the students in the experimental class, which worked under full-spectrum LED lighting for a year, passed the entrance exam for a bilingual high school, unlike the students in the other classes. The school’s headmaster confirmed that this was a unique achievement.
