A high profile, busy street in the centre of Torino has been the subject of a major lighting project to enhance the downtown area. The challenge involved upgrading 61 fittings by only replacing the lamps, to achieve improved visual comfort and urban security.
Research on outdoor lighting shows that white light with high color rendering not only improves visual comfort, but also enhances an area's livability by helping to maintain a driver's attention, thereby reducing the number of road accidents. The project therefore involved a ‘soft application', utilising lamps that are able to improve light quality, even when it is not possible to alter the street lighting design, in terms of new poles or luminaires.
GE ConstantColor CMH StreetWise lamps replaced high-pressure sodium yellow lamps in 61 fittings installed at 6 meters high with a wheelbase between 20 and 22 meters. This achieved the desired result as the lamp is designed to improve the light quality, with CRI 70 instead of CRI 25, providing energy savings, and a color temperature at 3000K. GE's StreetWise lamps will improve a light system's efficiency by about 17 percent and also allow the lighting flux to dim to 65 percent, saving energy during low traffic hours or low road use.
Results & Benefits
As a result of this installation, there is an enhancement of light necessary in this high-traffic area, without an increase in the wattage used, improving the social and functional environment. This first step for white lighting in Torino received very good feedback, which marks the opportunity for a more extended enrichment of the city.
