PWM dimming is a technique that switches the current on and off at a high frequency, varying the duty cycle of the pulses. The duty cycle is the ratio of the on time to the total period of the pulses. For example, if the current is on for 50% of the time and off for 50% of the time, the duty cycle is 50%. By changing the duty cycle, you can change the average current and thus the brightness of the LED. The frequency of the pulses should be high enough to avoid flicker and noise, typically above 360 Hz.

Below you can find all of our fixtures compatible with this lighting control method.
