Evaluation of Full-Spectrum Fluorescent Lighting

Jennifer Veitch and Shelley McColl published a paper in 2001, Evaluation of Full-Spectrum Fluorescent Lighting, which reviewed research studies on lighting from 1945-1998. While old fluorescent lights with flickering ballast can cause headaches, poor visual performance and even behavior problems for children who are overly sensitive, the new full spectrum fluorescent lighting has been found to improve visibility, reduce hyperactivity, reduce fatigue and improve health. Full spectrum light is designed to mimic the full spectrum of sunlight.

Light is measured in spectral power distribution and radiant energy. Lamps types are given in either CT (Color Temperature) or CRI (Color Rendering Index). Good fluorescent lights for children should have a color temperature of 4100 degree Kelvin and a color rendering index of 80 or greater. If there is adequate ceiling height in the classrooms, the better quality of reflected, ambient lighting from pendants or recesses is strongly preferred to troffer-style fluorescent fixtures. Fluorescent lights cannot be used with dimmers.
