1. Power density selection:
The power density of traditional lamps is 10-25 watts/square meter. The power density of LED flood lights can be designed at 3-15 watts/square meter.
2. Power selection:
The power of LED flood light is considered as 1/4 of the power of traditional high-pressure sodium lamp.
3. Power factor:
The power factor of LED flood lights is above 0.95, while the power factor of traditional high-pressure sodium lamps is around 0.6.
4. Power efficiency:
The power efficiency of LED flood lights is above 0.9, while the power efficiency of traditional high-pressure sodium lamps is around 0.6.
5. Service life:
The life of the LED flood light source is 100,000 hours, while the life of the traditional high-pressure sodium lamp is 3000-8000 hours.
6. The use of LED lighting can reduce the capacity of lighting cables and transformers. Compared with traditional lighting, it can reduce the investment of transformers and cables by at least half.
