I would like some feedback on this spreadsheet please. Any validation will be appreciated as I am a Noob, albeit and old Noob. It would seem that I can find lots of calculators on the Interwebs that calculate power stuff, but none that tell you how many power supplies you will need for the number of lights you have to power. I'll be certain that I'm not the first to stumble across this, this so any feedback will be appreciated, even if I didn't look in the right places to find the work someone else has already done. https://app.box.com/s/rbz71ox0mojasxdly6zf1ifr9if30o6j or https://docs.google.com/a/peterit.com.au/spreadsheets/d/17ZHai00nZJ17gZ8tmoY3glXQpd0EjhW8--GLJKwzkEs/edit?usp=sharing ComPeter Light em up.
