Abstract
An arc tube assembly () for a protected high intensity discharge lamp. The assembly has a ceramic arc tube () with a short shroud () surrounding at least the arc chamber () of the arc tube. The short shroud () allows the frit seal areas () of the arc tube capillaries () to project beyond the shroud () and thereby operate at a lower temperature, thus increasing lamp life.
