Since Scheers was growing very high quality roses with this system, he did not want the greenhouse to become too warm. Scheers says, “For years I’ve been looking for a way to buy as little electricity as possible, because this energy comes at a high price due to the transport and distribution costs.” The only way to increase the lighting capacity was to install energy-efficient LEDs.
Scheers has been a Philips and Codema customer for years. “After a few discussions it was clear to us that we should increase the size of this trial to the entire greenhouse of 1.5 hectares,” says Scheers. “If you want to do a trial, you have to do it right.”
The nursery purchased a new lighting installation consisting of two lines of Philips GreenPower LED toplighting. The capacity of the new lighting system is over one-and-a-half times higher than the old system. Despite this, much less heat is produced. Scheers can use the LEDs and HPS lights separately from each other.
When just the LEDs are on, there is 50% less heat produced compared to the old system. Scheers expects that he can turn on the lights for 500 to 750 hours more per year thanks to the ‘cool’ advantages of the LED toplighting. By installing this system, Scheers did not have to adapt the power supply of the company.
