The robust Philips OptiVision LED lighting scores very well in terms of light pollution – and that’s great for local residents. What’s more, with these new lamps there’s no warm-up time, so the lights are only switched on when people are actually playing. That means the lights are on for a much shorter period of time. Since these lamps last for 40,000 hours, they won´t need to be replaced for 20 or 25 years anyway. And this is a modular system, so if there’s a fault in the driver, for example, you can just replace the driver rather than replacing the whole lamp. That keeps additional costs down. The floodlights can also be dimmed. Unless there’s a tournament taking place, they are dimmed down as standard to 70%, which also saves money. Léon van Leeuwen from the Dutch National Tennis Association (KNLTB) praised the club for making the switch to OptiVision LED: "TV Markant is setting a good example and this could also encourage other tennis clubs to follow suit."
