Steve, I'm happy about my setup now since the performance (if we had tested it underwater) would be close to that M59 400W system w/ different brand bulbs. Kudos to you though for that excellent system you built. I think what we all need to realize is that all you are doing is just gathering data. (You take a system, describe the components, measure the PAR, publish your results.) How different people extract that data and turn it into information to form their own conclusions is up to them. What you have shown is that your system has more par than mine and thats all that I think you are trying to conclude in your original post (My E. ballast system vs your M80 ballast system). But then I think the other data that you posted (though interesting too) added to some confusion which always leads to frustration.
