Full Spectrum Lighting
The merits of full-spectrum light are highly debated. Many swear by full-spectrum and the health benefits it is purported to provide, and many others insist that all of the benefits are a placebo-like effect caused by brilliant marketing. What is true about full-spectrum light is the lack of industry standards or specifications as to what it is, so that incandescent light, fluorescent, UV ray emitting lights, and non-UV lights can fall within the full-spectrum, well, spectrum.

Features Claimed by Full-Spectrum Manufacturers: - Simulates the spectrum of natural light
- Spectrum of natural light varies through out the day, but these lights do not vary as the daylight does
- Improves visibility
- Improves health, productivity, and SAD conditions
- Makes spaces appear brighter and have a daylight-like feel
|
Some of the Realities of Full-Spectrum Lighting: - No scientific evidence of health benefits
- Expensive and produces less lumens per watt than other light sources
- Lumens: rate at which lamp produces light
- Excellent CRI (color rendering index) rank, which means colors appear natural
- Does not enhance visual performance
- Visual performance: speed and accuracy of processing achromatic information

What full-spectrum light claims to do sounds great, but with the steep increase in price for a light that has an almost identical spectral power distribution as incandescent and fluorescent light, it will behoove you to investigate these claims further.
