Light emitting diode luminaire device and system with color temperature tunning

A lighting device is disclosed that includes one or more master circuit boards configured to power light emitting diodes. The lighting device also includes modular light boards with arrays of light emitting diodes that interchangeably couple to the matched connectors on the master circuit board. The master circuit boards and the modular light boards are positioned within a housing with one or elongated diffuser lenses covering or embedding rows of light emitting diodes on the modular light boards. In accordance with the embodiments of the invention, master circuit boards and modular light boards are mounted in a stacked arrangement to emit light from opposed sides of the housing. In further embodiments of the invention, the lighting device includes a controller for independently controlling light output from each master circuit board.
