Pink lamps
FC Utrecht started using two sets of new lamps in December last year. Those purple-pink ‘assimilation lamps’ ensure that the grass grows better in the winter when there is little light and heat entering the stadium.
The minimum requirements for the quality of the grass were tightened by the KNVB last year, the Utrecht club emphasizes. “FC Utrecht was the only paid football organization in the Netherlands that did not yet use this lighting,” explains a spokesperson. “Given the tightening of the requirements, this was no longer sustainable.”
