<p>An light emitting diode (LED) retrofit system (106) for fluorescent lighting systems including a fluorescent lamp fixture (104) is disclosed. The fluorescent lamp fixture (104) includes a frame (112), an existing ballast (114) configured to be coupled to an AC power source, and at least one connector (108, 110) coupled to an output of the existing ballast (114). The connector (108, 110) is configured to be coupled to a fluorescent lamp. The LED retrofit system (106) includes at least one pin (122a-n) configured to be removably coupled to the connector (108, 110), and to receive a high voltage AC signal from the existing ballast (114). The LED retrofit system (106) includes at least one LED light source (120), transformer circuitry (116) coupled to the pin (122a-n) and configured to receive the high voltage AC signal and to output a low voltage AC signal, and rectifier circuitry (118) configured to receive the low voltage AC signal and generate a DC voltage to drive the LED light source (120).
