Guang Zhou Tian He Stadium Centre
Location: No. 229, Tian He District, Guang Zhou, Canton Province, China
Project Challenges
- The stadium had an aging 2000 W MH light that showed heavy light depreciation, making it less than ideal for a world-class tournament.
- Small installation arm only allows 1 point tighten.
WTA lighting standards based on ITF requirement
- According to the WTA, lighting must be evenly distributed throughout all areas of the court and have a minimum recommended intensity of 1076 LUX (i.e., equivalent to 100-foot candles placed on the court) – based on an -average of over 15 on-court readings.
- For optimal high definition television broadcasting, the standards are even higher – with the recommended lighting being at least 2,000 lux (i.e., equivalent to 185-foot candles placed on the court). Additionally, the light must be distributed across the court to create a consistent color temperature for broadcast audiences to enjoy the action with outstanding clarity, day or night.
- High/low ratio: To meet the standards required of a world-class tournament like the WTA Tour, the highest to lowest lighting readings’ ratio should be no greater than 1×2.0 – with the most desired ratio is 1×1.5.
