Just for you Bill... I just returned from Grants (yes it is 1:30am).
I will be doing more tests tomorrow night in the pool with some light meters and more pictures then in the garage for some min/max/average light output analysis. It will probably take me a day or so to put the results into graphical format. I will probably start a new thread because the original thread is way too big and contains lots of irrelevent stuff that takes too long too load.
My apologies to Grant. This was supposed to be done over a month ago but the premature arrival of my twin baby boys created a huge distraction and bumped this task off my list until this weekend.
