In 2013 vander Harg started using a new 7000 m 2greenhouse for blooming.Van der Harg wants to be recognized forthe superior and consistent quality of itsplants. In order to realize this ambition,the new greenhouse is illuminated usinga hybrid lighting system based on acombination of 1000 W HPS and LEDtoplighting. ‘Other projects have alreadyproved that the installation of LEDsolutions facilitates management,’explains Leo van der Harg. ‘Thiscombination makes it easier to controlthe growing Conditions.’A plant specialist from Philips wasclosely involved in the realization of theproject in order to ensure the bestpossible lighting design. The energysavings achieved by using a combinationof LED and HPS amounts to more than10% compared with illumination basedsolely on HPS. It is precisely because theplants are illuminated for so long thatthe pay-back time for the investmentmade by Van der Harg is relatively shortand the savings on production costs aresubstantial. Another advantage is that,because LEDs are being used, theexisting electricity connection isperfectly adequate and there istherefore no need for additionalinvestment in the CHP system. ‘Theinvestment will pay for itself straightaway, not just because of the energysavings but also because of theimprovement in plant quality,’ van derHarg says.“The investment will pay for itself straight away,not just because of the energy savings but alsobecause of the improvement in plant quality”22 Philips Horticulture LED Solutions - General booklet
