Sr. Mechanical Engineer

Oreon is a Dutch innovative developer and manufacturer of high-tech LED grow lights for greenhouse horticulture. Oreon started researching and intensively testing the fixtures nearly 15 years ago. The first commercial project involving the use of the unique water-cooling concept of the LED fixtures in a greenhouse was completed in 2009. Since then, Oreon’s LED fixtures have been used above different types of crops all over the world. Because of the unique water-cooling technology, the fixture not only produces a lot of light but also the right spectrum for each crop. LED fixtures can fully replace the existing, traditional lighting in a greenhouse or can be used in combination with them. In view of the globally rising demand for greenhouse lighting and the desire to consume less energy, Oreon creates a wide range of options for new, efficient and innovative lighting with its LED grow lights.
