I noticed today that when my 36W PC
Actinics kicked on they stayed kinda reddish for a while and slowly turned blue (maybe over 5 min) and the ends where the ignitors are stayed red for about 3 min longer. So it took about 8 minutes for the bulbs to be completely blue.
This has not been the case in the past. Does this mean the ballast is going, or is it the bulbs?
