This study collected data on the physical development, attendance, and school performance effects of four types of school lighting on elementary students over a two-year period. Results indicated that regular exposure to the lights had important nonvisual effects on students. Full-spectrum fluorescent lamps with ultraviolet supplements were found…

A two-year study in Alberta on the effects of classroom lighting found that elementary school students exposed to full-spectrum lighting with measurable ultraviolet output had fewer dental caries, larger gains in height and weight, larger gains in achievement, and better attendance. Students exposed to high-pressure sodium vapor lamps had the…

Results from a pilot study of four different lighting systems indicate that over a two-year period, light had measurable and significant effects on students. Under full-spectrum fluorescent lamps with ultraviolet enhancement, students developed fewer dental cavities and had better attendance, achievement, and growth and development than students…

This report describes a 2-year study of the effects of various lighting systems on elementary school students' dental health, attendance, growth and development, vision, and academic achievement. The four light types used were: (1) full spectrum fluorescent; (2) full spectrum fluorescent with ultraviolet light supplements; (3) cool white…
