Apparently I smoke way to much marriage-you-wanna! As I was preparing the third light to connect to the others I realized that this MH had a long skinny bulb. Hmmmmm I thought. That pot I just tasted was good. Oh ya, the light. Aren't long skinny ones HPS? So, I go take a look at the balast and it says "use 1000 wt HPS bulb only." Duhhhhhh. Take another hit! All along I thought I had a 1000 wt MH and it was an HPS. Oh well, when all is said and done, I will still get over 300K lumens for about 18 cents per hour. Including my (2) 400 wt MHs for Mothers and Babies I will pay about $100/mo extra in electricity for the whole show. Still doing ok I say!
