## Abstract

A lighting system includes a plurality of light fixtures. Each light fixture includes a sensor for performing a test on the light fixture an generating test data. The light fixtures also include a hardware processor and a radio communication module. The radio communication module can communicate the test data to a mobile computing device or to a node. A diagnostic software application can receive the test data, identify a malfunctioning component, and order a replacement component.

## Claims

### Claim 1

A lighting system, comprising:
a light fixture;
at least one sensor installed in the light fixture, the at least one sensor for performing a test of the operation of the light fixture and generating test data;
a hardware processor installed in the light fixture, the hardware processor configured to receive the test data from the at least one sensor;
a radio communication module located within the light fixture and in communication with the hardware processor, the radio communication module for communicating the test data wirelessly to a mobile computing device; and
a diagnostic software application that executes on the mobile computing device, the diagnostic software application comprising instructions for evaluating the test data, identifying a malfunctioning component of the light fixture, and providing a prompt to order a replacement component.

### Claim 2 (depends on 1)

The lighting system of claim 1, further comprising a computing system for receiving the test data from the mobile computing device and storing the test data.
