VISUAL DESCRIPTION
In this classic black-and-white advertorial image from Mazda Lamps' Lighting Advisory Service division under British Thomson-Houston Co Ltd., we see an 'Integrating Photometer,' a device used for measuring light intensity comprehensively across all angles emanating from a source—in this case likely evaluating lamp efficiency. A technician stands beside the large-scale photometer at BTH Research Laboratories in Rugby; his presence provides scale and humanizes what might otherwise be seen as cold scientific endeavor. The ad underscores research dedication behind lighting technology aimed at improving product quality—a testament to innovation efforts during that era.
