A club in South Delhi built a beautiful hard-court tennis surface, proper fencing, and a clay surface — everything right — then cut the lighting budget. Eight 150W LED floodlights, positioned wherever the poles happened to be convenient. Total spend: ₹1.2L on lighting. Measured output: 90–110 lux at the baseline. The court was unplayable after sunset, which in North India from October to February is before 6 pm. Eight months after opening, the club spent another ₹3.5L replacing the poles and retrofitting correct luminaires. The original system was not just dim — the pole positions were wrong, and wrong poles mean rewiring plus new foundation sleeves.
Tennis court lighting is where the easiest project saving becomes the most expensive mistake. This guide gives you the numbers to get it right before the concrete for the pole foundations is poured.
Lux Levels: What ITF Requires
The International Tennis Federation (ITF) specifies: Class IV (recreational club) — 200 lux average; Class III (regional competition) — 300 lux; Class II (national competition) — 500 lux; Class I (broadcast) — 750 lux with vertical illuminance requirements. Measure at court surface, 1m above the playing area, averaged across a grid of measurement points.
| Use | ITF Class | Lux (average) | LED system cost |
|---|---|---|---|
| Recreational / private | Class IV | 200 lux | ₹3–4.5L |
| Club competition | Class III | 300 lux | ₹4–6L |
| State / national | Class II | 500 lux | ₹6–10L |
| Broadcast / premier | Class I | 750+ lux | ₹12–20L |
Note that the lux level is an average over the court, not a minimum at the brightest point. A court lit to 200 average lux may have bright spots at 280 lux and dim spots at 140 lux. The uniformity ratio (minimum ÷ average) must be at least 0.5 for Class IV and 0.6 for higher classes. A badly positioned lighting system can meet the average lux requirement while failing on uniformity — which means shadows in the mid-court and service box where the ball is hardest to track.
Cost Breakdown by Lighting Level
The ₹3–6L cost range for a standard tennis court LED system includes: poles and foundations (₹1–2L), LED fixtures (₹80K–2L), wiring from main panel (₹50K–1L), sub-panel and switchgear (₹30K–60K), and installation labour (₹40K–80K).
The biggest cost variable is the LED fixtures themselves. Commercial-grade sports LED floodlights (the type that maintains output at 40°C ambient) cost ₹8,000–20,000 per fixture. Budget LED floodlights from general lighting suppliers cost ₹2,000–5,000 per fixture and are rated at 25°C — in a North Indian summer, their actual output drops 20–30% below the rated specification. For a tennis court, always specify sports-grade fixtures with a defined lux output at 40°C.
LED vs Metal Halide
LED is the only sensible choice for a new tennis court lighting installation. Metal halide has a 5-minute warm-up delay before it reaches full output — which means if the lights trip during play (a monsoon-triggered RCCB trip, for example), the court is dark for 5 minutes after reset. In a commercial court environment, that is a client complaint every time it happens.
On a cost-per-lux basis at the fixture: LED at 150W produces approximately 20,000 lumens. Metal halide at 400W produces approximately 35,000 lumens. So you need roughly half the number of watts for the same lux output with LED. Over a 10-year period at 5 hours/day and ₹8/unit electricity, the difference in running cost between an LED system and an equivalent metal halide system is approximately ₹3–5L — more than the LED upgrade premium at installation.
Pole Placement and Height
Standard pole placement for a tennis court: poles must be a minimum 3m outside the sideline (safety clearance), positioned between the baseline and service line. For 6m poles at 200 lux, you need 4–6 poles per side. For 8m poles, 3–4 per side is typically sufficient.
Taller poles give better uniformity because the light angle to the court edge is less extreme — a 6m pole at 3m from the sideline shines at a steep angle toward the far side of the court, creating a hot spot near the pole and a shadow zone at the far side. An 8–10m pole at the same position has a shallower angle and distributes the light more evenly. The tradeoff is that a foundation for a 10m steel pole is more expensive and requires deeper concrete embedment (typically 1.5m vs 1m for a 6m pole).
Poles behind the baseline (on the end lines) should be minimum 3m behind the baseline for safety. These poles provide the critical end-zone lighting that prevents the shadowing that makes serving difficult with side-only lighting.
