Hi Sir, I got a led project that I assume is similar to your "step 4" the ac transformer.I have a power supply that step down to 9VAC and 200ma. I am using the 1 watt LED, which is exactly the one you have on your step 7.My question is: I assume I can put minimum 8? : 4 in series ( 9 x 1.4= 12.6v) and 4 more on the negative cycle. My second question is: What is the max number I can put them? I assume is 15 x 8, so 120?Thank you for your time and the help
