(this is my first post)
We have a fluorescent lighting fixture in our kitchen (typical office light...two bar lamps, if that's what they're called). It is at least 5 years old, probably older.
In our location, it is frequently very humid (>80%). On humid days when we open the house, the light does not come on at all or one of the lamps comes on about 1/3 partial brightness.
Sometimes, we can make it come on by flicking the switch rapidly on/off.
Is this a feature of fluorescents?
Should we look at the starter or ballast or what?
thanks in advance
