The LED spotlight C1-mini-HC can be dimmed using a dimming pin. The sensor is located directly at the cable entry in the spotlight base. Place the dimming pin in the sensor area. As soon as the green feedback LED at the cable entry lights up, the sensor is activated and the spotlight is dimmed. Removing the pen stops the dimming process. When the dimming pen is placed in the sensor area again, the dimming direction is changed. The value is automatically saved after approx. 5 - 10 seconds and is retained even after a power failure. The dimming range is flicker-free and can be adjusted from 100% to 1% in 256 steps. (dimming frequency approx. 20 kHz) The spotlight is set to 100% at initial start-up.
