Unique lighting systems were developed for bulthaup b3 that can be integrated seamlessly into the characteristic joint pattern of the multi-functional wall. These lighting systems can generate either diffuse, general light or a targeted, warm spotlight. The result is pleasant background lighting that also offers perfect illumination of the working areas. Interesting shadow effects also add to the solution's allure. The wing lights, which also form a functional and formal part of the functional boxes, can be attached in three grid positions in order to provide various areas of the work surface with dazzle-free illumination. The flat swivel lamps can be rotated by 270° around their axis. The design of both types of light is reduced to its formal essential. Long-life halogen or fluorescent bulbs ensure excellent light output, a long service life, high energy efficiency and a pleasant, warm light.
