Yes and no -- they've got a somewhat unusual spectrum and they have
special ballasts and a large preheater.  The latter two differences
from your run of the mill fluorescent lamp are meant to make them
more useful for enlarging by reducing the warm up time that causes
problems for short exposures.

These are worthwhile differences but with an enlarging timer that
measures light output, like the Metrolux, much less so.
