Tennis Court Lighting: Lux Standards, Pole Layout and LED Floodlights

A well-lit tennis court can be used for four or five more hours a day, which changes the economics of clubs, schools and hotels. Good lighting also has to stay out of players’ eyes at every angle of a serve and out of neighbours’ windows. LED floodlights with asymmetric optics have made both much easier.

Court dimensions

• Playing area (doubles): 23.77 × 10.97 m
• Recommended total area including run-off: about 36.6 × 18.3 m (120 × 60 ft)
• Lighting covers the whole total area, because players run well beyond the lines

Light levels

From EN 12193:

Televised events need vertical illuminance for cameras and follow broadcaster requirements.

Pole layouts

Poles stand along the long sides, outside the fence and away from the baseline area, so players do not look into lights when serving or lobbing. For multiple courts side by side, poles between courts serve both.

Pole height

• 8 m (26 ft): recreational, single courts with low neighbours
• 9–10 m (30–33 ft): club courts, better uniformity
• 12 m and above: large complexes, competition

Higher fittings can be aimed flatter, which reduces glare and spill.

How many floodlights

A first estimate with the lumen method:

Lumens needed = target lux × area ÷ (utilisation factor × maintenance factor)

For a single outdoor court at 300 lux over 36.6 × 18.3 m (670 m²), with a utilisation factor of about 0.6 for good asymmetric optics and a maintenance factor of 0.8:

300 × 670 ÷ (0.6 × 0.8) ≈ 420,000 lm

At about 120 lm/W that is roughly 3.5 kW: for example 8 poles with one 400–500 W fitting each, or 12 fittings of 300 W. At 200 lux, roughly two thirds of that. A photometric calculation with the real fitting data confirms the count and uniformity.

Optics: why asymmetric matters

Symmetric floodlights must be tilted up to throw light across the court, which sends glare into players’ eyes and light into the sky. Asymmetric sports optics throw light forward while the fitting stays nearly horizontal:

• Less glare for players looking up
• Less spill over the fence and into neighbours’ gardens
• Better uniformity across the court

Our modular LED sports floodlights (50–300 W) have asymmetric 140° × 80° optics with a 30° offset, or 155° × 80°, designed for tennis, basketball and five-a-side courts.

Glare and spill control

• Keep fittings at 0–10° tilt where possible
• Add shields or visors on the back side
• Avoid poles behind baselines
• Check light at neighbouring windows in the design
• Use 4000–5000K but avoid excessive brightness above Class requirements

Indoor courts

Indoor tennis needs higher levels (300–750 lux) and very good glare control, because players look up at the ball against the ceiling. Fittings are mounted along the sides of the court rather than above it, with indirect light on a light-coloured ceiling. LED high bays with wide optics and diffusers or asymmetric linear fittings are typical. See our gym lighting guide for sports halls in general.

Controls

• Coin, card or app-operated switching for public and club courts
• Timers that turn lights off at a set time
• Two levels: training and match
• Instant on: LED needs no warm-up, so lights can be switched per booking

Switching per booking saves a lot over leaving all courts lit all evening.

Converting from metal halide

Many courts still have 1,000–1,500 W metal halide floodlights. LED replacements at 400–600 W per position usually give the same or more light with better uniformity. Check that existing poles and crossarms can carry the new fittings; LED is usually lighter. See the LED stadium lights guide for larger sports facilities.

Cost drivers

Retrofits on existing poles are much cheaper than new installations.

Maintenance

LED floodlights on tennis courts need little attention: clean the glass once a year, check aiming after storms and confirm that timers and booking systems switch correctly. Keep a record of aiming angles so fittings can be reset after maintenance. Check pole bases and anchor bolts for corrosion every few years, especially at coastal clubs.

Multi-sport courts

Courts marked for tennis and pickleball, or tennis and basketball, should be lit for the most demanding sport and level of play. Check that poles and fittings do not sit in the run-off of any of the marked courts.

Ordering

Send the court layout, number of courts, level of play, any existing poles and the distance to neighbours. We will propose floodlights, a pole layout and a photometric estimate.
