Abstract
A light fixture can be affixed within a wall and powered using the same cable along which data signals are transmitted. The LED lights in the light fixture are sufficiently bright to be used for illumination and are powered by a voltage derived from power delivered via the data cable. The light fixture may be used in conjunction with a building automation system. The light provided by the LED lights may be modified based on control signals received via the data cable. Modifications may include changes to the perceived brightness and/or color of the light.
