Ed, yes, I had bad bulbs and that was why I started this thread to begin with. I got my 2 new replacements and only 1 stayed the right color. I then went through 3 bulbs only on the right side of my 120g. One stayed the correct color for about 30min., then I got the next replacement and it stayed white for 3 days then went yellow, the I got the next replacement and it stayed white for about an hour. I took the blub that stayed white the longest and put it on my single pfo ballast on my 180g tank and within the day it turned back to white.
I then put it back on my 120g on the right side and it has stayed white ever since. I put another of the yellow ones back on the 180g and it is still yellow.
