Case Study: 70W HPS Comparison
Comparing a 70W HPS to a PICOLUM 1 streetlight installation
Specifications Road: B1 classified road + 1.5m setback
The PICOLUM 1 provides a 78% 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.
