Here is a professional answer in English for the lighting specifications of a 60m x 40m football field.
The number and wattage of LED Stadium lights depend heavily on the intended use of the field and the required illumination level (measured in Lux). There is no single answer, but here are the standard recommendations based on different competition levels.
Summary of Recommendations:
| Competition Level | Required Illuminance (Lux) | Mounting Height | Recommended Layout | Estimated Quantity | Recommended LED Wattage (per fixture) | Total Approx. Power |
|---|---|---|---|---|---|---|
| Training / Recreational | 200 - 300 | 8m - 10m | Four-Corner | 20 - 24 | 200W - 400W | ≈ 7,200W |
| Amateur / Club | 300 - 500 | 10m - 12m | Four-Corner | 24 - 30 | 400W - 600W | ≈ 12,000W |
| Professional | 500 - 750 | 12m - 15m | Side-Mounted | 30 - 36 | 600W - 800W | ≈ 21,600W |
| TV Broadcast | ≥ 1000 | 15m - 18m | Side-Mounted + Corners | 36 - 48 | 800W - 1000W | ≈ 38,400W |
Detailed Breakdown:
1. For Training & Recreational Use
Illuminance: 200 - 300 Lux (average maintained)
Layout: Four-corner mounting is most cost-effective.
Poles: 4 poles, 8-10 meters high.
Quantity: 5-6 fixtures per pole.
Fixture Wattage: 200W - 400W LEDs.
Estimated Total: 20 - 24 fixtures.
2. For Amateur & Club Matches
Illuminance: 300 - 500 Lux
Layout: Four-corner mounting is still suitable.
Poles: 4 poles, 10-12 meters high.
Quantity: 6-8 fixtures per pole.
Fixture Wattage: 400W - 600W LEDs.
Estimated Total: 24 - 30 fixtures.
3. For Professional / National Level Matches
Illuminance: 500 - 750 Lux
Layout: Side-mounted (2-side or 4-side) is preferred for better uniformity and reduced glare for players.
Poles: 4-6 poles, 12-15 meters high.
Quantity: 6-8 fixtures per pole.
Fixture Wattage: 600W - 800W LEDs.
Estimated Total: 30 - 36 fixtures.
4. For HD TV Broadcast / International Matches
Illuminance: 1000+ Lux (with very high uniformity requirements)
Layout: Side-mounted on multiple poles, often supplemented with corner poles. This is essential to meet strict vertical illuminance (for TV cameras) and eliminate shadows.
Poles: 6-8 poles, 15-18 meters high.
Quantity: 6-8 fixtures per pole.
Fixture Wattage: 800W - 1000W+ high-performance LEDs.
Estimated Total: 36 - 48+ fixtures.
Crucial Technical Factors to Consider:
Luminous Efficacy: Don't just look at Watts. Look at lumens per watt (LPW). High-quality stadium LEDs should provide 130-160 LPW or more. A 600W fixture with high efficacy will be brighter than a 800W fixture with low efficacy.
Beam Angle: The choice of beam angle (e.g., 20°x60° for narrow, long-throw) is critical for directing light precisely onto the pitch, improving efficiency and reducing spill light (light pollution).
Uniformity: This is as important as the Lux level. Good uniformity (Uo = Emin / Emax) ensures no dark spots. Good design aims for Uo > 0.7.
Glare Control: Optics and correct mounting height are vital to prevent discomfort for players and spectators.
Color Rendering Index (CRI): For TV broadcast, a CRI >80 (preferably >90) is mandatory for accurate color reproduction.
Color Temperature: A neutral white 4000K - 5700K is standard, providing clear visibility similar to daylight.
Final Recommendation:
For a standard 60m x 40m field intended for serious amateur matches, a solid starting point is:
24-30 units of 500W LED floodlights
Mounted on 4 poles at 12m height.
Ensure all fixtures have IP65 waterproof rating and a 5-year minimum warranty.
Important: This is a general guideline. For a precise and guaranteed solution, it is highly recommended to consult with a professional lighting designer or supplier. They can perform a Dialux simulation based on the specific fixture's IES file to provide an exact plan guaranteeing lux levels and uniformity for your project , you can see more information on http://www.benweilight.com
