Some 1,800 lights in Dublin’s 9km Port Tunnel have been replaced with LEDs, cutting their energy use by around 60%.
Signify, who did the job, says it’s saved enough electricity to power 300 Irish homes.
The lighting expert added that they reused the 17-year-old fittings, reducing waste and helping Transport Infrastructure Ireland save millions in costs.

Patrick O’Hanlon, Senior Engineer at TII, said “We are delighted to have worked with Signify on this project.
“The replacement of the original SON lamps with LED inserts is a huge step towards reducing the carbon emissions, energy consumption and future maintenance of the Dublin Port Tunnel, while also improving overall lighting and power quality.”
The new lights were fitted at night and into the early hours over the course of five weeks to reduce disruption.
Sean Campbell, Key Account Manager – Road Lighting, Signify Ireland, “Dublin Port Tunnel is unique in Ireland and high traffic flows from the port of Dublin.
“Collaborating with the customer who trusts Signify to deliver on a circular economy project that reduces energy consumption while increasing the power factor has been a real pleasure.”
The project is expected to save upwards of €4 million in electricity costs including VAT over five years while reusing the existing fittings for all light points saved an estimated €3 million.
Dermot Deely, Managing Director, Signify Ireland, said “With public lighting accounting for 24% of Dublin Council’s energy expenditure, energy efficiency projects like this one can make an enormous positive impact.
“Through a relatively simple upgrade, we’ve been able to improve light quality, cost, maintenance, and sustainability for Dublin Port Tunnel.
“We are particularly proud to have supported these environmental goals while giving a second life to many of the materials that were already in place.”
The project is part of the Irish government’s energy efficiency plans and was partially funded through the European Green Deal.
