Abstract
The invention relates to a lamp unit provided with a mercury vapor discharge tube and a stabilization ballast which forms one mechanical whole therewith. This lamp unit is provided with a lamp base of a type which is customary for incandescent lamps. In accordance with the invention the discharge tube is a low-pressure discharge tube having a relatively high arc voltage. This results in a lamp unit whose ballast portion is small.
