The filament coatings wear out, and there is some kind of degradation
due to migration of the mercury that I can't remember the details.
It's probably a generic germicidal lamp, and you can get them from
your friendly neighborhood electrical supplier. You might also check
at a barber supply store cuz they use germicidal lamps. Some UV lamps
are designed to put out light at ~180 nm as well as ~260nm and
generate a lot of ozone. I don't know if that's what you want or
not. Take your old lamp to the electrical supplier and order a new
one from its numbers.
