[QUOTE="David_AVD, post: 80767, member: 94"] The board needs to see the AC (currently via the 2.7M resistor) to do the timing for the phase control. I guess you could try changing R1 to around 2.2K and R2 to 220K and see how that goes. For 8 LEDs, you'd need about 20VAC while 10 LEDs would require about 24VAC. Each LED string will also need a current limiting resistor; maybe 470 Ohms at a pure guess? You could start higher on that and decrease the value for increase the brightness. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
