As part of new works to install new safety railings to the famed Whispering Gallery at St Paul’s Cathedral, CBG Light Perceptions was appointed to devise a new lighting scheme to align with the new design.

St Paul’s is recognised across the globe. The original lighting design dated back 25 years which included cold cathode tubes, dimmed halogen lighting and metal halide fixtures which were common technologies of their time. The re-engineering of the design by CBG is part of a larger programme to upgrade the interior lighting of St Paul’s to more energy efficient light sources.

CBG specified iGuzzini’s Linealuce linear fixtures. This contemporary, high-performance miniaturised luminaire has replaced 64-metres of cold cathode fittings to provide uplight to the beautifully gilded, heritage Tijou railings. A warm white colour temperature has been specified. To offer improved illumination to the Thornhill frescoes, which adorn the dome of the gallery, CBG used iGuzzini Palco luminaires with a variety of carefully selected optics. These are controlled in a series of zones to highlight the most important elements of the painting and replace the older metal halide and halogen spotlights.
