Does this condensation have to do with quality of the lamp?
Not at all, assuming it is the mercury (so it evaporate with the lamp warming up).
This phenomenon could only not present, when the arc tube have excessively high thermal losses on some spots (oversized seals,...), causing the mercury to first condense there.
But well thermally balanced arc tube will always condense on the metal electrode first, so yielding this fogging after following turn ON.
