1. A lighting apparatus, comprising:
a first light source having multiple first LED modules;
a second light source having multiple second LED modules; and
a driver for control the first light source and the second light source to generate an output light of a required mixed color temperature, wherein the driver selects a first subset of the multiple first LED modules and a second subset of the multiple second LED modules to generate a first output light with a first color temperature, wherein the driver selects a third subset of the multiple first LED modules and a fourth subset of the multiple second LED modules to generate a second output light with a second color temperature, wherein the first light source has a color temperature between 2700K to 7000K, wherein the second light source has a color temperature between 1800K to 5500K, wherein a target color temperature mixed by the first light source and the second light source is between 2580K to 6020K.
