The gases (or vacuum) inside electric bulbs is usually specific to what kind of bulb it is. It can be repaired, by separating the glass from the metal, replacing/correcting whatever is broken, and resealing it in an environment that will have only that specific gas (or vacuum) inside. It can be repaired, but it's at least the same effort/expense (probably more) as making a new bulb.
