The Link lighting system, designed by Ramon Esteve, is a series of four different-sized square and rectangular modules with a matte white or charcoal-gray finish that can be joined in any configuration for a wide variety of ceiling silhouettes. The modules range in length from 45 inches long to 15 3/4 inches wide. The modules can connect on any of their four sides and simply require that there be a 5 1/2-inch overlap of surface area. A single electrical connection can support up to eight modules. Link is fully dimmable using a zero-to-10V electronic dimming ballast, has a polycarbonate diffuser, and uses two, 2G11 lamps from 18W to 40W, depending on the size of the module selected.
