Hello John.....glad to meet you. To answer your questions about why I'm using a bridge rectifier....
1. I'd like to minimize the soldering work I'd have to do per LED,
2. I have the bridge rectifiers from other projects, so I thought I'd put them to good use.

I used 16V output based upon the voltmeter reading. But I think I see my error. The voltmeter is giving me a false reading?

I can use resistors based up on a 28V peak. But for me to undestand what you're saying, I should not plan circuits using the average voltage, but use peak voltage? I did some research and found the following formulas.....
PeakV = RMSV * 1.414 26.2V = 18.5V * 1.414 ....... which is the value I should use?
AverageV = PeakV * .637 16.7V = 26.2V * .637 ......... which is the value I DID use (matching what the voltmeter showed).

Am I on the right track here?
