How come my PFO dual 175W ballast does not light equally?

For some reason my ballast does not light my hamilton 14k's evenly. One is noticably brighter than the other one. I switched the plugs around and the brightness switched too. Is something possibly wrong with one of the internal ballasts? Thanks!

if you are using the same bulb but get different results, then by process of elimination its the ballast.

Is that what typically happens with ballasts, they either stop working or do not work as well as before?
