A lighting apparatus, comprising:

• a driver with a power converter and a controller;
• a light source, wherein the power converter contains a current source to generate a driving current to the light source;
• a light holder for fixing the light source, wherein a holder bottom of the light holder defines a light opening, wherein the light source emits a light from the light opening;
• a first switch for users to operate to adjust a setting, wherein the light source comprises multiple types of LED modules with different light parameters, wherein the setting corresponds to a mixed light parameter of the multiple types of LED modules;
• and
• a second switch for users to operate to adjust the setting, wherein the first switch is concealed, wherein the second switch is placed on the light holder exposed for a user to operate, wherein the first switch and the second switch are coupled to the controller, wherein the second switch is coupled to the driver via a switch conductive path, wherein the second switch is enabled when the driver supplies electricity to the second switch, wherein the first switch is operable to change the setting even when the first switch does not receive electricity from the driver.
