Saint-Louis lighting is sold by configuration rather than by SKU. A Royal chandelier alone exists in eight to forty-eight lights, in short and long drops, and every one can be specified with a different frame colour, cups, hurricanes, lampshades, pendants, octagons, chains and upper arms. Weights run from 2.5kg for a sconce to 178kg for a forty-eight-light chandelier. Showing that range on paper, or physically, is not practical.
The iPad app carries three linked tools. A catalogue covering the Light, Tableware and Decoration, and Prestige ranges, filterable by category and style. A photo library of real installations, including the French Embassy in Washington, the Royal Evian Hotel and Restaurant Kei. And a real-time 3D configurator with a light on and off toggle and a view from underneath, which is how a chandelier is actually seen.
A configured piece can then be placed into a photograph of the client's own room, with controls to line the image up against the walls and ceiling so the scale reads correctly. Product data, dimensions and weights are carried in both metric and imperial, in French and English.
