1. A lighting system comprising elongated LED light fixtures each having;
a) a master circuit board with connectors configured to power LED arrays;
b) a set of light boards with the LED arrays, the light boards having matched connectors to detachably and interchangeably couple to the connectors on the master circuit board, wherein the LED arrays on each light board within the set of light boards include LEDs that emit different output spectra that combine to produce a combined output light intensity and a combined output light color temperature from each light board within the set of light boards; and
c) a control interface device coupled to a control unit for simultaneously selecting the output light intensity and the output light color temperature; and
e) a white light sensor coupled to the control unit for automatically adjusting relative intensities of the different output spectra to maintain the output light intensity and output light color temperature based on changes in amounts of white light from ambient light.
