Signify supplies lisianthus grower SenZaro with Philips GreenPower LED toplighting for the second time this year  

The current HPS installation supplies 300 µmol/s/m2. A third of the lights will be replaced by the Philips GreenPower toplighting Force grow lights this autumn. These grow lights have an output of 3600 µmol/s, boosting the light level to 400 µmol/s/m2, without further technical adjustments or increased energy usage.

The toplighting Force is available in two beam widths: a wide beam giving uniformity in relatively low greenhouses or with little distance to the crop, and a standard beam offering optimal yield in higher greenhouses. Zwinkels chooses this last option, offering an efficiency of 3,5 µmol/J. “Thanks to the higher output less lights are needed.” Zwinkels adds. “That lowers the costs of the installation a bit.”

In the adjusted chrysanthemum greenhouse, the first growth of lisianthus under the new lighting regime has now taken place. The grower is happy with the results. "The branches have more buds and are really a lot heavier," he says. "That's what it was all about for me because I grow for the top segment of the market and see great prospects in lisianthus of a heavier, and therefore of a higher, quality. More light was wanted, and I certainly didn't want more radiant heat. That makes LED the best option to increase weight."
