1. A dimmer comprising:
a primary intensity actuator coupled to a primary intensity potentiometer, the primary intensity actuator structured to be actuated for at least one of:
controlling an amount of power delivered to a load connected to the dimmer between minimum amount and maximum amount of power in normal operation mode, and adjusting light intensity based on a first user input in the normal operation mode;
selecting a type of end trimming based on a second user input before entering configuration mode; or
adjusting, based on a third user input, an end trim value during the configuration mode;
a configuration actuator arranged on a side of the dimmer and structured to be actuated for entering the configuration mode based on a fourth user input within a first predetermined period; and
a controller coupled to the primary intensity potentiometer, the configuration actuator, and a driver circuit coupled to a bidirectional switching device, the controller structured to control dimmer operation comprising receiving a voltage signal based on variable resistance from the primary intensity potentiometer, receiving a mode selection signal from the configuration actuator, and transmitting a dimming signal to the driver circuit for driving the bidirectional switching device, the dimming signal based at least in part on the voltage signal,
wherein the end trim value comprises at least one of a low-end trim value or a high-end trim value;
wherein the type of end trimming comprises at least one of a low-end trimming or a high-end trimming;
wherein the second input comprises:
actuating the primary intensity actuator above a high threshold for high-end trimming; or
actuating the primary intensity actuator below a low threshold for low-end trimming, and
wherein the third input comprises:
actuating the primary intensity actuator to a new high-end value for high-end trimming; or
actuating the primary intensity actuator to a new low-end value for low-end trimming.
