I need a circuit designed (please include part numbers). The circuit will allow LEDs to be powered by 120 AC 60 Hz and must allow the LEDs to be dimmed by a device that I have that uses Pulse-width modulation. I will use the circuit to build 3 seperate devices, 1 using Green LEDs, 1 using Red and 1 Blue. The output of the LEDs should be close to the output of a 10-20 watt incandesent light bulb and should have a beam width should atleast 60 degrees and should allow atleast 6 LEDs bulps. The circuit also should allow any number of the LEDs to fail without having any negative affect on the others.

I can help you with your project. I have extensive experience with pwm control of multi-channel Hi-power led systems up to several hundred watts. We would need to clarify the details.
