My CSL 65W PC
light is a little over a year old. The light was going out and then coming on after an hour or so. I figured it was the light, so I changed it.
But now it seems to go off for a few hours, and then kick in and work properly. So I was wondering how long a ballast supposed to last? I've had absolutely no problems with the light until this month.
And if it is the ballast, how easy is it to remove the old one and install a new one?
