		hey troy 
what type of ballasts.  i think that is the key, at least for the 400W we use, cuz we tried the 6500K non-R on cap/coil ballasts and it was GREEN.  not a bit yellow, but almost a lime green!  just curiuos if you had success with cap/coil ballasts of if yours are electronic. 
could be too that the 250W responds differently on the cap/coil than 400's.
