A device comprising a solid state or mechanical switch coupled to a first connector and a second connector and at least one lighting device such as an LED light source wherein when power is applied to the first connector, the switch is operable to direct power to the lighting device and to a portion of the pins of the second connector. By constructing the connectors as similar, but with opposite genders, the connectors can be disposed on a circuit assembly to allow for daisy chaining a series of luminaire assemblies together. The connectors may be Ethernet connectors and the switch may be operable through control signals coupled to the Ethernet connector such that a smart power controller operating using power over Ethernet (POE) can operate to control the light sources.
