ONE OF THE FEW remaining sections of sodium lighting on the M62 motorway in the north of England has gone LED, resulting in energy savings of 48 per cent.
The M62 is one of the major motorways in the UK and at 102 miles long, it acts as the west-east trans-Pennine motorway in Northern England that connects major cities the likes of Liverpool, Manchester and Leeds.
The average daily traffic flow on the M62 can reach around 150,000 vehicles a day.
Highways England Area 12 – the body responsible for around 12,000 luminaires across the region’s entire major roadway network – wanted to replace the existing 250W and 400W sodium lanterns between junction 25 to 28 which have been coming to the end of their functional life.
Aone+, the asset managers, worked together with Holophane using a mix of the latter’s innovative V-Max luminaires, which can be scaled with LED modules in the shape of chevrons.
Aone+ chose fittings with both 2- and 4-chevron luminaire sizes. Outputs used ranged from 6,000 lumens to 21,000 lumens with wattages from 51W to 208W.
Compared to the existing 400W lanterns, the efficiency of the V-Max luminaires offered energy savings of at least 48 per cent.
In the unlikely even a chevron may fail, this can be easily replaced in situ on a column.
Additionally, this modular design mitigates against complete luminaire failure as the chevrons are separate; meaning that entire luminaires will not need replacing.
The modular slimline design of V-Max (the V2 is 8kg while the V4 is 11kg) significantly reduces the asset weight and makes it easier for users to handle and install onto columns.
The colour rendering index of the lanterns (70CRI) gives road users a better visual acuity, as compared to the existing lanterns whilst driving.
McCanns was contracted to install the lanterns.
