Mar 27, 2017: Four Dutch companies have launched some horticultural lighting trials in the Netherlands by using colored LED lighting.
The Dutch companies—Villa Gerbera, Gebr. Koot BV, Together2Grow and Slijkerman—are testing how LED lighting impacts growth and quality of tomatoes. They are, in fact, trying out colored LED lighting on other plants as well. The trials will evaluate the effectiveness of LED lighting on the yields of tomatoes.
Plessey has announced these four horticultural lighting trials in the Netherlands as they are using fixtures developed by the company. The trials will examine the impact on growth rates, crop yields and plant quality with Plessey’s high-performance LED lighting.
Plessey LED grow lights have been installed along with the existing high-pressure sodium grow lights, which is considered to be the most efficient way to add extra light to give better crop yield. It also minimises energy usage and additional heat load inside the glasshouse. Plessey is taking keen interest in the horticultural space with the signing of a licensing agreement with PhytoLux in 2016.
Plessey sees horticulture as a potential opportunity to supply its GaN-on-Si LEDs. Plessey was already making blue emitters to be used in its white LEDs. However, Plessey needs to source red LEDs to deliver horticultural lighting products. Plessey’s Hyperion 1000 and 1600 LED fixtures can directly replace high-pressure sodium (HPS) lamps and cut energy consumption by 40%. The trials will continue to run throughout summer of 2017.
