Got my ACL strobes, thank you very much AAH/Bird for doing the work for them. I have a couple questions. Looking at the build doc, I'm and trying to compare to mine. I'm assuming the Gray wire is the positive and the white is the negative? Does it matter which end you power from, they are not directional like pixels? Last but not least I have a Lynx MR16 I was hoping to use with these (http://www.diylightanimation.com/wiki/index.php?title=DC16Use). I've got some buck converters to take the 12v down to 5v (http://www.ebay.com/itm/191521008762?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT). Is this type of hookup possible? If so what would be the best hookup, negative on the negative from the channel and then the positive from the power supply? Thanks in advance.
