Abstract

An outdoor light fixture having a lamp sensor and a management server is provided. The lamp sensor is utilized for assessing depreciation of light output of a light emitting diode (LED) light engine of the outdoor LED light fixture. Collected data can be sent to a management server for analysis to determine life expectancy of the light fixture and also determine power levels. The power levels may be applied to the light fixture to maintain a constant lumen output or lower output to meet life expectancy requirements. The performance of the outdoor light fixture having the lamp sensor may be utilized to gauge the performance of similar outdoor light fixtures without lamp sensors.
