Case Study: 70W HPS Comparison
Comparing a 70W HPS to a ZIYA-E street light installation
Specifications Road: B2 classified road + 2m sidewalks Luminaire spacing: 52m Road width: 7m Height: 7m
The ZIYA-E provides a 70% energy saving compared to a 70W high- pressure sodium luminaire, while fully meeting the road light level requirements. Furthermore, a much better colour rendering index is provided, thereby enhancing the safety and visibility of pedestrians and road users.
