Pixel Sharp projected imagery inspired by the Bayeux Tapestry onto the White Cliffs of Dover for a one-night British Museum event. The location had limited access, no mains electricity and a narrow nighttime operating window, so the technical design had to minimise vehicles, lifting equipment and crew.
Four Panasonic RQ35K 4K laser projectors were arranged as two double-stacked pairs. The complete system ran from portable battery power. Stacking increased usable output and provided a geometry that a small team could transport and install within the available period while covering a very large, irregular natural surface.
The production lesson extends beyond projection. Equipment selection was based on the full deployment cost—weight, access, setup time, power and staffing—rather than a brightness figure in isolation. That is particularly relevant to temporary outside broadcasts and live events where infrastructure cannot be assumed.
The case study confirms projector count, arrangement and battery operation, but it does not publish throw distance, projected area, measured luminance, power draw, runtime margin, weather data or alignment method. Supplier commentary also does not quantify contingency capacity if one projector or battery chain failed.
