Full-spectrum fluorescent lighting (FSFL) has been credited with causing dramatic improvements in vision, perception and cognitive performance as compared with other fluorescent lamp types. These effects are hypothesized to occur because of similarity between FSFL emissions and daylight, which is said to have evolutionary superiority over other light sources. This review, covering 1945-98, crit...

The technology used in energy-saving compact fluorescent lamps (CFLs), provides a quarter of the energy consumption of incandescent lamps to produce equivalent light energy while CLFs shelf life is up to ten times of incandescent lamps. So the incandescent lamps in homes and workplaces are replaced with CFLs. Due to the use of ballast in the structure of CFLs, electric and magnetic fields are g...
