A lighting fixture includes a solid-state light source, communications circuitry, a memory, and processing circuitry. The memory stores common security credentials, wherein the common security credentials are pre-installed during a factory calibration process. The processing circuitry is coupled to the solid-state light source, the communications circuitry, and the memory. The processing circuitry is configured to cause the solid-state light source to provide a desired light output. Further, the processing circuitry is configured to join a common network using the common security credentials, wherein only devices with the common security credentials are permitted to join the network.
