The biggest problem is the amount of current the light needs, would blow out that pot instantly. The pot says 2 watts, but the light says 18 watts.

The best plan would to be do what cars do with LED interior light dimming. They use PWM pulse width modulation. It's changing the duty cycle of a mosfet that's turning on and off really fast. Maybe something like this? https://www.amazon.com/dp/B07HN1BJWK/ref=cm_sw_r_cp_apa_i_b4NgEbA4V1HV3

Edit: or are you going for a constant brightness and just need to drop the voltage? Because there's a different way to do that. Voltage regulator.
