If you are going to run 20K lamps and e ballasts you wont have much PAR. I'd go through and see which 20K lamp has the highest PAR on the IC ballasts and go with them. My 14K EVC's running an EVC e ballast measure 55 on Sanjay's site and in the real world I get over a little over 90 on the bottom of the tank (18" below the surface)
