What is full spectrum light?

Full Spectrium lighting

Full spectrum light is commonly defined as a light source with a color temperature between 5000K and 6500K and a CRI above 96. 

However, since sunlight varies in color temperature throughout the day – warmer during dawn/dusk, cooler and whiter throughout the daytime – we find the above definition to be incomplete.

We owe this definition of full spectrum light to studies done in the 1960s which showed how plants could grow as well under an artificial light source containing a fuller, more complete spectrum of visible light as they would under natural daylight.

While many may like to define full spectrum light as one in the “cooler” daylight white color temperature range, all variations of sunlight are still full spectrum and beneficial – they just have different effects!

Full spectrum lighting can mean any bulb that either: 

A) contains a full visible light spectrum and the non-visible light spectra of infrared and/or ultraviolet.

B) contains a balanced and full visible light spectrum (regardless of color temperature)

Most full spectrum light bulbs go via the second definition, containing a balanced visible light spectrum, since the first definition is nearly impossible to achieve in an ‘artificial’ light source.
