St. Peter’s Church in Tewin, Hertfordshire, is Grade I listed and required some updated lighting to improve efficiency and reduce running and maintenance costs, whilst offering more flexibility than the existing lighting offered. Existing lighting consisted of expensive metal halide lamps which are now difficult to find and costly to run, along with tungsten halogen lighting which again is expensive to run. A lighting design was provided, using LED light fittings with dimmable controls to offer some flexibility to the installation. At the request of the church and DAC, the existing wiring was to be reused where possible to help reduce installation costs. Following a full inspection of the existing wiring, which was found to be suitable for continued use, we offered a flexible solution to greatly increase overall illumination, enhancing both the worship and general use of the church. A bank of dimmer switches provide some control over the new lighting meaning the church now has a level of adjustment for any service or event.
