Many of the suburbs of Milton Keynes are now mature, with their infrastructure such as street lighting requiring an upgrade to meet current standards. For the side roads of the housing estate of Stantionbury, Council Lighting Engineer Alan Coleman chose 250 Arc lanterns from WRTL Exterior Lighting to ensure optimum efficiency and light pollution control, at a competitive price.Alan Coleman comments: "We selected the Arc because the lanterns offered excellent value for money, impressive performance and tight distribution control. Its stylish aluminium body is almost totally recyclable, which was also very attractive to us. With 50/70W SON-T lamps, we achieve good colour rendition, with a shallow bowl for a gently lit appearance, yet with very good cut-off."
"The lanterns are mounted on 5 metre columns, a height suited to a residential area. As the columns just needed refurbishing, we were able to concentrate on the performance of the lanterns. Arc can be mounted both post top and side entry, so we installed side entry lanterns on the bus route through the estate, with 0.5m arms to minimise the possibility of any collision; in the residential areas post-top lanterns were preferred".
WRTL's vandal-resistant, Arc units are available in two sizes, and are compatible with a wide range of SON and full spectrum lamps, giving visual uniformity in all road types. The aluminium castings utilise WRTL's long experience in marine lighting where long, corrosion-free life is paramount. In addition, Arc is almost completely recyclable to meet future recycling requirements, making it future proof from this perspective.
The stylish Arc has specially designed, high performance optics offering excellent uniformity, a key factor in any lighting design. In addition, Arc has double ingress protection with the entire body sealed to IP 66 and the optic sealed separately. In order to avoid any potential for a build-up of condensation after lamp heating and cooling, both compartments feature controlled breathing technology (CBT). Safe access to the inside of the body is assisted by an auto-disconnect facility.
