A system and/or a method reads, measures and/or controls intensity of light emitted from a light-emitting diode (LED). The system and/or the method have a light intensity detector adjacent to the LED for reading and/or measuring the intensity of light emitted from the LED. The system and/or the method have a control circuit that may be electrically connected to both the detector and/or the LED for measuring and/or for controlling an intensity of light emitted from the LED. A housing surrounds the light detector and/or the LED. The housing has a pathway that allows only light emitted from the LED to reach the light detector. The LED has a finish and/or a coating that eliminates and/or retards absorption of light by internal components of the LED. The finish and/or the coating eliminates and/or retards reflection of the light by the LED.
