BEAR Scotland, a leading infrastructure management and maintenance organisation, selected Zeta Specialist Lighting’s Solar LED Brick to illuminate a cycle path adjacent to the A9, north of Perth, a project it was managing for its client Transport Scotland.
A cyclist fatality on the A9 dual carriageway highlighted a pressing requirement to illuminate the adjacent 1.5 km long cycle path, to encourage more people to use it during the hours of darkness. In consultation with the local council, BEAR Scotland, which is responsible for maintaining Scotland’s trunk road network in the North East and North West, looked for a solution that would enhance security and improve visibility for cyclists and pedestrians in the evenings and early mornings.
Ensuring the safety of drivers was of paramount importance. BEAR Scotland didn’t want to install lighting that could potentially distract drivers on that stretch of the A9 and as the cycle path is sited in a rural location, it was essential that the lighting was not intrusive, which ruled out street lighting.
There were additional cost implications associated with laying the infrastructure for an on-grid solution, and BEAR Scotland also wished to avoid painting white lines as it’s a shared facility remote from the carriageway and this would present an ongoing maintenance requirement.
BEAR Scotland selected the Zeta Solar LED Brick, an off-grid
LED solution that produces effective, even illumination and which is waterproof, shock and pressure resistant.
“High level lighting was not suitable in this area,” explained Eric Hill, Senior Engineer Road Safety, BEAR Scotland North West Unit. “The Zeta Solar LED Brick provided us with an ideal solution for this unique requirement.”
The Solar LED Bricks were installed along the centre of the path at 18 metre intervals where there were no hazards, and at nine metre intervals at give way points.
One of the biggest benefits is that the Solar LED Bricks sit flush along the path, unlike cat’s eyes which sit proud on the surface; meaning there are no bumps, which eliminates the risk of cyclists hitting them with tyres or pedestrians tripping over.
Hill added: “There is no other product like it. We are also considering other locations where we can install Solar LED Bricks to provide illumination.”
Compared with traditional lighting, Zeta’s Solar LED Bricks delivered a cost-efficient, long-term sustainable solution. The overall environmental impact of solar-powered lighting is much lower than a mains-powered solution. Both the cost and time associated with installation is also significantly less; running costs are zero, and as the typical lifetime of the LEDs is 39,500 hours, there is no requirement for ongoing maintenance.
