ARCHIVED - Full-spectrum Lighting
Several articles addressing the question: Does the scientific evidence show that dramatic improvements are possible in academic achievement, health, mood, & office work performance, if full-spectrum fluorescent lamps are used in place of other lamps?
One definition of a full-spectrum fluorescent lamp is that it has the following characteristics:
- a correlated colour temperature of at least 5000 Kelvin or higher;
- a colour rendering index of 90 or higher;
- a spectral power distribution that includes all parts of the visible spectrum (380 - 780 nm); and,
- some emissions in the near UV (roughly, 340 - 380 nm).
Some people claim that full-spectrum lighting has beneficial effects on human behaviour and health. NRC-IRC's Lighting Group has investigated this question in several ways, resulting in the publications linked below.
