Signify, formerly Philips Lighting, has installed LED lighting in two French horticulture farms in order to optimize production and reduce energy costs.

Jardins Réunis and Cheminant have both installed Philips GreenPower LED toplighting and Philips GreenPower LED interlighting in their new cucumber greenhouses in the Nantes region of France. Signify said these are the first growers to use LED lighting to grow high-wire cucumbers in the country.

The lighting will help increase the production and yield of the cucumbers while also enabling growers to increase light levels without increasing heat. Additionally, the lighting will reduce overall energy costs for growers compared to traditional horticulture lighting.

The lighting in both Jardins Réunis and Cheminant were installed in newly built semi-closed greenhouses. The 25,000 square meter (m2) facilities were installed in November of 2018 with 145 micromoles per second per square meter (µmol/s/m2) toplighting and 67 µmol/s/m2 interlighting LEDs. This was the first growing season for both companies to make use of the system, Signify said.
