Valoya Research

High quality light produces high quality plants

Plants’ photoreceptors receive information from light that determines their morphology and chemical composition. Light that stimulates the widest range of photoreceptors produces strongest, healthiest plants.

A Research Driven LED Manufacturer

Valoya’s Research and Development focuses on two major topics: Plant Light Response Research and LED Technology Research. 

The goal of all Valoya Research is to deliver the maximum value to our customers by lowering costs associated with production processes and enabling more revenue. 

This can be achieved through better light quality, while saving energy compared to traditional lights, translating into increased productivity, improved quality and/or faster production cycles.

Some of the research is conducted by Valoya alone and some in collaboration with the world’s leading research institutes and universities such as Max Planck Institute, John Innes Centre, Julius Kühn Institute, Wageningen University, etc.

Valoya's Lights in Academic Studies

Over 60 published research projects have used Valoya LED grow lights. 

Research Data

Some of our research data are available on the internet, some we present at various conferences and some we share under NDA agreements.

This data is used to create light plans for our customers whereby we advise the lamp model, spectrum and the correct positioning for the plant, growth stage and goal that the growers wishes to achieve.

Otherwise, some of the research data we share in our webinars, conferences or during various speaking engagements at tradeshows and symposiums such as GreenTech, Seed Meets Technology, etc.

Trial, Arabidopsis Thaliana

Below is the data from one of 500+ plant trials Valoya has conducted thus far.


Being sessile, plants are constantly competing with other plants for light, living space, water, and nutrients. Competition for light causes morphological and developmental changes in plants. Plants have the ability to sense small changes in the spectrum, intensity and direction of light. Photoreceptors sense these light signals making possible the acquisition of information ‘used’ to adjust plant development. Three major groups of photoreceptors have been identified; red and far-red sensing phytochromes; UV-A and blue light sensing cryptochromes.

By knowing the photobiological background of different species, we can design light spectra suitable for multiple species. By modifying a spectrum we can for example maintain the vegetative stage of the plants longer and delay flowering in many species.

The research was made to study the effect of different Valoya light spectra on the growth and morphology of Arabidopsis thaliana.
