WRTL wins contract to supply 28,000 Arc street and highway lanterns

(15/11/2008)

Following the award of a £150 million PFI lighting scheme agreement by Norfolk CC to Amey plc, the contract for supplying lanterns for the initial part of the scheme has been won by WRTL exterior Lighting, with 28,000 of its Arc street and highway lanterns chosen for the county roads, streets and residential areas.

“Arc was selected because of its excellent distribution with glare control to meet the provisions of BS EN 13201, its ability to accommodate both SON-T and CosmoPolis lamps in the same design and its high sustainability, both in energy efficiency and recyclability,” said Amey Project Manager Tony Drury.

“We will now have a uniform appearance for street lighting across all parts of the county, whether for 400W main road lighting, 150W side roads or 70W residential areas. We will also be installing WRTL’s advanced 2-Tone street lantern at a later date in the project.”

Martyn Wegg, Norfolk CC Street Lighting Manager adds: “The first five year phase will see around 24,000 columns and lanterns replaced. The columns have exceeded their design life, the lanterns are inefficient and do not meet current requirements for street lighting. There will be an additional 4,000 or so new lanterns installed to bring complete roads up to standard rather than leave a mix of lighting standards.

“An important part of the scheme design is residents requested a ‘white’ light source to improve visibility for added security and confidence, so a scheme which incorporates high efficiency lanterns in both white and modern SON-T sources within the same design of luminaire was popular.”

WRTL’s 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 IP66 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. Arc‘s 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. WRTL’s new 2-Tone is the first street lantern designed specifically to conform to the strict S1 G6 Glare classification for light pollution nuisance in built up areas, with advanced 3-D optics and flat glass for minimum light spillage.
