The focus of the upgrade is one of the main routes into Southampton, the section of the M3 between Junctions 13 – 14, near Chandlers Ford. EM Highway Services operates and maintains this portion of the M3 on behalf of the Highways Agency.
In identifying the new lighting, the use of sustainable practices and the desire to find the most efficient solution were key considerations, especially as monitoring of energy usage on this section revealed that the lighting was the main energy user.
The upgrade to LED involved replacing existing 250W and 150W high pressure sodium fittings with Luma 3. A total of 476 Luma 3 luminaires were installed, creating even light levels and distribution across multiple lanes, whilst adhering to strict lighting standards.
A modular solution, Luma 3 provides great flexibility through a choice of LED configurations combined with a variety of high performance optics to deal with the multiple lumen package requirements of at times a 10 lane arrangement.
