A lighting assembly is provided that includes a white LED and a reflector assembly, wherein the surface of the reflector assembly selectively reflects a portion of the output from the LED in a manner that results in a color temperature shift of the light output from the LED. To produce the color shift in the light output, the reflective surface of the reflector assembly is coated with a thin film of material. The coating causes a shift in the composite light output from the LED in combination with the reflector that moves towards a lower color temperature or a warmer hue. In turn, the shift produces a composite light output that exhibits a greatly improved color rendering index, while also maintaining a high level of efficiency for the assembly as a whole.
