An aircraft passenger cabin 1 is provided with ceiling and/or wall lights 11, 13 with LED light sources. The light sources are programmable via an interface for calibrating light intensity and/or colour of a light output of the light sources, for example to match the output of a replacement light to that of existing lights. The light sources may be programmed remotely via a wired or wireless link, such as an infra-red link. |
