The glass of the normal fluorescent lamp acts as a pretty good
shortwave UV filter. Otherwise the things would be dangerous.

Shortwave UV lamps use a quartz envelope rather than glass, and
ceramic windowed EPROM packages use a quartz window. This makes
the lamps and the ceramic windowed packages are more expensive than
they would otherwise be.
