21. An LED lighting element for use in a fluorescent lighting fixture, comprising:
-
a first end cap formed as a printed circuit board for connecting with and obtaining physical support from a first socket of the fluorescent lighting fixture; a second end cap formed as a printed circuit board for connecting with and obtaining physical support from a second socket of the fluorescent lighting fixture; a blade supporting one or more LEDs between the first and second end caps; and a power converter located in one or both of the first and second end caps; wherein the power converter converts power from the fluorescent light socket into power for operating the LEDs.

22. A flow-through LED lighting system, comprising:
-
a housing; a plurality of blades disposed within the housing, each blade being proximate to at least one venting space; a plurality of LEDs configured with the blades; at least one optical element for conditioning the light emitted by the LEDs; at least one sensor for sensing one of movement, light level, smoke and sound; a waveform analyzer for determining a power level based upon an input waveform from an external power source; an actuator for rotating at least one of the blades; control circuitry for controlling output of the plurality of LEDs based upon input from the at least one sensor and the power level and for controlling the actuator to rotate the at least one blade in response to detected movement; a power supply for converting power received from the external power source to supply the at least one sensor, the control circuitry, the actuator and the plurality of LEDs; wherein the at least one venting space allows air to flow past the blades to dissipate heat generated by the LEDs.
