Instead of trying to add layers/distortion to reduce brightness, has anyone tried using a potentiometer as a dimmer switch ?
Reduce V IN and output will drop accordingly. I used to make LED annunciator panels. To get the clients attention where it was more critical we used different values of resistors. The rule is you can overdrive the LED until it gets warm safely. Run the voltage up until it gets hot(very briefly), back down until its only warm, then measure the ohms of the pot. Place a fixed value resistor of that value inline with the pot and it will prevent the hand on the pot from blowing anything.
Keep us posted !!!!
