No worries about the questions… ask away and I will do my best to answer them.
On my setup the LED lights are not dimmable so I regulate lighting with hanging height. That makes the use of a relay switch simple to control them… just on/off
This module costs about 10 bucks and has 8 relay channels:
If your lights are dimmable then that adds complexity to it. I understand most if not all LEDs are dimmed using PWM (pulse width modulation) so the current/voltage stay constant but is switched on/off very fast every second to create a duty cycle.
If the duty cycle is 50% (half output) the current might be on for a total of 1/2 second out of the total 1 second cycle. 25% will be 1/4 second… but it happens many, many times per second so you don’t get flicker.
The only way I see you can do this is get into your lighting control and see what is controlling the dimming, could be just a simple resistor function like a potentiometer.
