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.

„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.”
Gianluca Ragaglia, Regional Sales Manager, Italy
