Case Study: 400W HPS Comparison
Specifications
Road: A1 classified road + 2m setback Luminaire spacing: 36m Road width: 10.5m Height: 10m
The LEDLUME-MAXI provides a 36% energy saving compared to a 276W 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.
