How Is Tennis Court Lighting Designed for Night Matches?

The rookie mistake in tennis lighting is designing for horizontal footcandles on the court surface — the number that looks good in a proposal. Players do not watch the surface; they watch the ball in the air. So I design for vertical illuminance: light arriving horizontally at the ball's flight height, measured in both directions along the court axis. That requires fixtures on both sides of the court aimed across, not just down. The uniformity target applies to the vertical planes too — a ball that disappears into a dark zone at the service line is a lost point. I check the model at multiple heights, from the net cord to the top of a lob, because the whole flight envelope has to read clearly.

Tennis poles are shorter than range poles but still real structures: I engineer the poles and foundations for the fixture load and the site wind speed, with anchor bolt details suited to the soil. Electrical feeders run underground to each pole — no overhead lines near courts — with a disconnect at each pole base for maintenance. The control panel gives the club scheduling, dimming presets, and curfew shutoff. Neighbor relations get designed in, not apologized for later: I calculate spill light at the property lines and nearest windows, specify house-side shields where needed, and document compliance with the local lighting ordinance for the permit. A tennis club that loses its lighting permit over neighbor complaints has an expensive dark facility.

Tennis lighting commissioning happens after dark with players hitting. I meter light levels at the grid points from the model — horizontal and vertical — and have players confirm they can track serves, overheads, and lobs without glare. Aiming gets fine-tuned fixture by fixture; the model gets you close and the eye finishes the job. Spill light gets measured at the property line to confirm the permit conditions, and the control presets get programmed and labeled. The club staff learns the scheduling system and the curfew routine. Here is the checklist I hand club operators.

• Design for vertical illuminance through the ball's flight envelope, not just horizontal footcandles
• Place 20-to-30-foot poles along the sides, clear of play, sharing poles between courts in batteries
• Specify sharp-cutoff optics with visors and verify glare from every baseline viewpoint
• Engineer pole foundations for wind load and run all feeders underground
• Meter and player-test after dark, confirm property-line spill, and program dimming presets
