Abstract: Light emitting device (LED) light fixture control systems and related methods are disclosed. A system and method in one aspect can include at least one LED configured to emit light at an illumination output level and at least one light sensor configured to measure the illumination output level of light emitted by the LED. A system and method can also include a control unit configured to detect the illumination output level emitted by the at least one LED falling below an original illumination output level and to increase the illumination output level by the at least one LED to produce a predetermined lighting level associated with the original illumination output level in an area.
