Back in 1998 we installed the Cathedral lighting at Christ Church. In 2019 we we were brought back in to upgrade and update the ageing system, which was no longer suitable for the environment. The solution was a complex phased lighting refurbishment.
Phase I works involved isolating and removing the North Aisle capital lights and the North Transept Clerestory lights before installing new LED lighting along with emergency lighting. We installed bespoke enclosed LED tape around the capitals of the North Aisle, high powered LED spots on the Clerestory of the North Transept, converted the Stall lighting in the Latin Chapel and installed high powered spot lights in the Watching Loft.
We carried out wiring using MICC cables and FP200 cabling, predominantly installed around the containment route on the Clerestory where a special harness and equipment was required for mobility. All the new lighting is scene functionable, with every circuit Bluetooth controlled via the Cathedral operator’s tablet.
Phase II works involved isolating and removing the lights in the South Aisle, the Choir Stalls, the Nave and the underside of the Organ Loft, then installing modern lighting to replace them. We incorporated the new lighting into the existing emergency lighting system using change over and hold off relays, and the same type of LED tape was installed around the capitals of the South Aisle.
We installed high powered spot lights on the Clerestory level of the Nave and recessed spot lights to the underside of the Organ loft. And we upgraded all the Nave Choir stall lighting from hot, inefficient halogen lamps to cool, high powered LED chips, with incorporated Bluetooth dimmer modules as an integral part of the circuitry.
