Artificial lights are a pre-requisite for plant production in no-natural light growing environments. In the absence of sun light the quality of the light (spectrum) is accentuated to the highest degree. As artificial light in no-natural light, is the sole source of light, higher light intensities are also required, than in many supplemental light situations.

Higher light intensity also leads to a higher thermal load to be cooled in these no-natural light environments. A superior light spectrum allows, not only for higher crop yields, but also for lower intensities and less energy consumed to cooling too, thus the benefit from Valoya’s lights is very high.
