No matter in power consumption or lighting effect, 400W metal halide flood light is more suitable for football ground lighting. In energy consumption, 400W metal halide flood light is less than half of the energy consumption of 1000W HID spot light. Therefore, 2000 pieces lamp, the energy consumption would be huge different and waste. 400W metal halide flood light with voltage stabilizer is able to accept the input voltage between 120V—220V AC. However, 1000W HID spot light only can accept the input voltage 200V--240V AC. The metal halide flood lamp is able to accept wide range voltage. For the HID spot light, when the voltage drops below 200V AC, the lifetime is going to reduce. In light effect, 400W metal halide flood light is also more suitable for football ground lighting. 400W metal halide
