Swedish lighting manufacturer, ateljé Lykta, has launched Vault, a modular multifunctional lighting system, in collaboration with London creative agency Fourmation. The key to the system is the four-way connection block that links ‘light bars’, allowing it to be laid out in a set grid formation or any combination of the module. It can even act as the ceiling itself, as interstitial voids can be fitted with stretch fabric, for instance, to create an instant suspended lighting grid, masking the soffit above. Not only can you mount it on walls, it comes with a smart phone app that allows users to modify lighting levels.
