8. The LED driver of claim 7 , wherein the controller is further configured to:

determine whether the toggle sequence of the switch matches an unlocked operation mode sequence; and

change the operation mode of the LED driver to the unlocked operation mode, wherein the one or more settings of the LED driver are adjustable based on the one or more toggles of the switch when the LED driver is in the unlocked operation mode.

9. The LED driver of claim 1 , wherein the controller is further configured to:

determine whether the toggle sequence of the switch matches a factory reset mode sequence; and

reset one or more settings of the LED driver to factory settings.

10. A lighting fixture, comprising:

a light emitting diode (LED) light source; and

a driver that provides power to the LED light source, the driver comprising a controller configured to:

detect toggles of a switch that controls whether electrical power is provided to the light fixture;

determine whether a toggle sequence of the switch matches a CCT adjustment mode sequence, wherein the toggle sequence of the switch comprises a sequence of one or more toggles of the toggles of the switch that the controller detects; and

change a CCT level of a light emitted by the LED light source if the toggle sequence of the switch matches the CCT adjustment mode sequence.

11. The lighting fixture of claim 10 , further comprising a non-volatile memory device, wherein the controller stores information related to the toggle sequence of the switch in the non-volatile memory device during a time period that the switch is turned on.

12. The lighting fixture of claim 10 , wherein the controller is further configured to change a CCT setting of the driver to the CCT level after entering the CCT adjustment mode.

13. The lighting fixture of claim 10 , wherein the controller is further configured to:

determine whether the toggle sequence of the switch matches a locked operation mode sequence; and

change an operation mode of the driver to the locked operation mode, wherein one or more settings of the driver are unadjustable based on the toggle sequence of the switch when the driver is in the locked operation mode.

14. The lighting fixture of claim 10 , wherein the controller is further configured to change a CCT setting of the driver to a second CCT level from the CCT level if no toggles of the switch are detected by the controller for a period of time after changing the CCT setting of the driver to the CCT level.

15. The lighting fixture of claim 14 , wherein the controller is further configured to change the CCT setting of the driver to a third CCT level from the second CCT level if no toggles of the switch are detected by the controller for a second period of time after changing the CCT setting of the driver to the second CCT level.

16. The lighting fixture of claim 15 , wherein the driver is configured to:

enter a CCT adjustment mode in response to the controller determining that the toggle sequence of the switch matches the CCT adjustment mode sequence; and

exit the CCT adjustment mode if one or more toggles of the switch are detected by the controller within the period of time after the CCT setting of the driver is changed to the CCT level or within the second period of time after changing the CCT setting of the driver to the second CCT level.

17. A method of controlling operations of a lighting device, the method comprising:

detecting, by an LED driver, toggles of a switch, wherein the switch controls whether electrical power is provided to the LED driver;

determining, by the LED driver, whether a toggle sequence of the switch matches a CCT adjustment mode sequence, wherein the toggle sequence of the switch comprises a sequence of one or more toggles of the toggles of the switch that the LED driver detects; and

changing a CCT setting of the LED driver if the toggle sequence of the switch matches the CCT adjustment mode sequence.
