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.

What is claimed is: 1. A light fixture for illuminating a room, comprising:a housing;a data cable receptacle attached to the housing, wherein the data cable receptacle allows connection of a data cable operative to deliver power and data;a power circuit connected to the data cable receptacle, wherein the power circuit produces a drive voltage from power delivered via the data cable;a control circuit comprising a processing device and a memory storing a network address associated with the light fixture, the control circuit configured to receive control signals on the data cable addressed to the light fixture with the network address and the processing device configured to execute instructions carried by the control signals;a sensor for sensing light conditions within the room and generating a sensor signal representing the sensed light conditions;a light emitting diode (LED) cartridge for illuminating the room comprising a plurality of LEDs arranged such that the plurality of LEDs forms a space on the LED cartridge in which the sensor is positioned, wherein the plurality of LEDs is powered by the drive voltage and controlled by way of the control signals received by the control circuit; anda non-opaque cover for covering the plurality of LEDs and comprising an unobstructed portion configured to allow the sensor to sense the light conditions within the room without any obstruction presented by the non-opaque cover.
