Dual redundancy high reliability LED lighting platform

An elongated lighting module having an asymmetric illumination source formed from at least two rows of light emitting diodes (LEDs) that extend along the long axis of the module and are independently controllable. The lighting modules are powered via a wiring harness that extends down a support pole to a power converter stack having LED drivers to control the modules. The power supply for lighting module includes a power enclosure having individual light emitting drivers for powering the rows of light emitting diodes that can adjust the power level to compensate for the loss of power from another of the light emitting drivers. The power supply may also include a backup that can be switched over to power the rows of light emitting diodes in the event of a failure.
