- No of High Mast – 4 Nos
- Height of Mast - 50 Mtr
- Flood Lights Per Mast – 82
- Total lights = 82 x 4 = 328 nos
- Flood Light Wattage – 2 KW
- Maximum Vertical lux achieved on ground (center) is approx. 500 Lux, while minimum (Near Goal Line & Corners) was approx. 200 lux
- Maximum Horizontal lux achieved on ground is approx.700 Lux, while minimum was approx. 250 lux
