Differnt bulb same ballast

[Estevon]

I just got a new setup.Galaxy ballast, radium bulbs.They have yet to burn in, Im going on week 2. So far so good. These radiums are very bright with a nice blue tint, but I would like to see them side by side with my old bulbs and the new ballast. Since I have this new ballast I might as well try the old bulbs for referrence.I would like to see what the old 12K reeflux looks like with the new ballast compared to the radiums. To make a long story short will this hurt the ballast burning 2 different bulbs.(By the way I really liked the 12K reeflux on my old probe start pfo old ballast, they never gave me any problems and burned for a year.

THNX IN ADVANCE

Nope, will not adversely affect the ballast to run either bulb. Its running a bulb that is going out that will be the problem.
