1. An LED light fixture comprising:
- at least two electrically operated LED light sources for emitting illumination, the illumination of each of said at least two LED light sources having different, predetermined correlated color temperatures; and
an electric circuit connectable to an electric power source for supplying electric power to one of the group consisting of a selected one of said at least two LED light sources and a selected combination of said at least two LED light sources, said electrical circuit comprising;
a switching circuit operable for connecting said selected one of the group consisting of a selected one of said at least two LED light sources, and said combination of said at least two LED light sources, to said electrical circuit to receive electrical current and emit illumination of a predetermined correlated color temperature;
a manually controllable correlated color temperature switching assembly to operate said switching circuit to connect said selected one of said group to the electric power source to effect the illumination of said selected one of said group of one of said at least two LED sources and a combination of said at least two LED light sources, said manually controllable correlated color temperature switching assembly including a digitally operated switch actuating member for actuating said manually controllable correlated color temperature switching assembly;
a switch holding structure for holding for operation said digitally operated switch actuating member; and
a concealment for concealing said switch holding structure to render said digitally operated switch actuating member inaccessible for operation, and for selectively rendering said digitally operated switch actuating member accessible for digital operation.
