For sports stadiums, I recommend using high mast lights as the best solution. Open spaces like sports stadiums generally require a higher lighting standard, which high mast lights can meet.

Specifically, I recommend the following pole heights and lighting fixtures:

• Pole Height Recommendation:
  Generally, the pole height for sports stadium high mast lights should be in the range of 25 meters to 40 meters.
  This height can provide sufficient lighting coverage while also avoiding interference with field usage.
• Luminaire Power Recommendation:
  For standard football/soccer fields or basketball courts in large sports stadiums, I suggest using 400-watt to 1000-watt high-power metal halide or LED luminaires.
  This power range can ensure adequate brightness on the field to meet TV broadcast and other high requirements.
• Luminaire Quantity and Layout:
  Depending on the field size, typically 8-16 groups of high mast lights are needed with a proper layout.
  The luminaires should be distributed evenly to ensure uniform lighting across the entire field, without any dark spots.
• Lighting Standard:
  According to international standards, the lighting level for sports stadiums should reach 500-2000 lux.
  If TV broadcasting is required, the lighting level should reach 1000-2000 lux.

In summary, using 25-meter to 40-meter high mast lights equipped with 400-watt to 1000-watt high-power luminaires is the best choice for sports stadium lighting. Please let me know if you have any other questions.
