How we work
LED is already invented, the efficiency is no question anymore and the spectrums are clear for most crops. However experience is the key to success. Without a community or neighbor grower with experience or one of our consultants to support you it is difficult to change to another strategy. For example going hybrid or to full LED makes a big difference in your climate management. If we can not introduce you to an experienced project we first should test in your production facility, or a similar situation to learn what changes will overcome to your company. We will not sell you just light, we sell you growth!
Spectrum tests and installation analysis
Together with the growers we have setup tests in production environments to improve the products, spectrum and strategy around the new lights. As always the goal is a better efficiency, but it does not stop at efficiency. We research installation efforts, wiring and cable methods and for example we aim to minimize the shadow inside the greenhouse.
Top light RA Series: air and water cooled comparison
Parus provides most of their lights in air cooled and water cooled. Back in 2010 – 2016 we had too much heat in the powerful light series, we had to remove this heat by using water. Later in 2018 the efficiency of the LEDs got better so water cooling got optional. Since 2020 we only use water cooling in places where we want to reuse the dissipated heat in other applications like heating pipes, storage or to heat up other rooms. Also we use it for saving on HVAC cooling costs.
The use of linear LED lights for greenhouses
Over the years we learned that our linear LED’s are not only suitable for multilayer installations. They can also be used for single layer purposes in greenhouses. In this case we used the PFL-WCIII Series to grow cucumbers.
