An identification and location module executing on calibration system transmits a message to instruct a first light emitting element included in a plurality of light emitting elements within the lighting system to emit light having a first characteristic. The identification and location module detects, via a photosensitive device, a first location of the first light emitting element within the lighting system based on the first characteristic. The identification and location module stores a data entry in a memory that associates the first location with the first light emitting element. At least one advantage of the approach described herein is that wireless light emitting elements are automatically identified and located during post assembly testing, thereby reducing labor costs associated with manually presorting or recording IDs of the light emitting elements. ## Claims ### Claim 1 A computer-implemented method for identifying and locating wireless light emitting elements within a lighting system, the method comprising: transmitting a first message to instruct a first light emitting element included in a plurality of light emitting elements within the lighting system to emit light having a first characteristic;
