Together with our sister brand Zumtobel Lighting and Callaghan Electrical Contractors, we helped create a new lighting scheme for one of the last substantial Roman Catholic cathedrals in Ireland.

Completed in 1942, the historic and spectacular Cathedral of Saint Patrick and Saint Felim is the most dominant building in Cavan Town. The monumental neo-classic architecture impresses externally with its 68m spire and flanking domes and is easily one of the town's most impressive and eye-catching buildings. Internally, it is vast and awe-inspiring, featuring 28 columns, but it was often viewed as gloomy. Ageing and soaring energy prices meant the Cathedral recently underwent a complete conservation, restoration and upgrade.

Kieran Callaghan, Managing Director of Callaghan Electrical, says, "In 2022, we were appointed as the electrical contractor to carry out the rewiring of this iconic building as part of the restoration project. The scope of essential works included replacement of the existing electrical installations throughout, fire safety installations and the integration of new technologies, whilst restoring, retaining and enhancing the integrity of the authentic historic fabric of the building." All new systems, including LED lighting, were threaded within the historic fabric of the building.

Kieran continues, "When it came to our lighting specialist, based on previous projects, we had no hesitation in working with Zumtobel and Thorn products. Their quality of products, lighting designs, service and availability has always been at the forefront of innovation." 

The Zumtobel Group's lighting brands provided a solution for each location, from the ornate interior to the showstopping exterior. The lighting approach differed from subtlety on the inside to showstopping outdoors.

Externally the lux levels have been optimised at the front façade and spire to enhance the cathedral’s historic and architectural beauty, with Thorn’s Contrast RGBW architectural floodlights with DMX controls. This will allow the cathedral to configure many different scenes to complement religious days, light shows and Irish events.

In addition, the exterior car park and cathedral entrance has been illuminated with Thorn’s Avenue D2. The luminaires have been customised to a specific RAL colour to complement the cathedral and the existing luminaires. With the upgrade of the external lighting, the cathedral is now a historic focal point, and its architectural beauty can been seen throughout Cavan town.

Ian Brodigan, Branch Manager Eastern Electrical Dundalk, comments, “When asked by Kieran Callaghan, Managing Director of Callaghan Electrical, who we would recommend as a partner on this job without hesitation Zumtobel and Thorn Lighting. As a major partner supplier, I felt that their design, technical expertise, and extensive product offering would enhance this iconic upgrade, and this proved to be the case. We at Eastern Electrical Dundalk are proud to be associated with both parties, and this upgrade has become a historical focal point for the town of Cavan. It is a visually stunning upgrade.”

Overall, the internal and external LED lighting provides an excellent low-energy solution with a very long life, reducing the need for maintenance and saving both cost and time.
