LOL The Difinitive answer has been provided to you Chris! No need for any more input I suppose.
Unfortunately that difinitive answer did not include any fixtures, nor did it take into account any loading, ambient light levels, positioning of fixtures, required or expected light levels of the finished product, use of the bridge, etc etc.
I dont know about you, but I have never been able to properly design a lighting system without actually seeing the location of the project! Pete must be just awesome and quite the magician.
Have a great day.
