ABSTRACT:
An amalgam is disposed within the arc tube of a high intensity arc discharge lamp so as to stabilize the electrical power being supplied to the lamp against variations in line voltage. The vapor pressure of mercury in the arc tube varies as a function of the lamp temperature which depends in turn on applied lamp voltage. The resulting change in arc voltage due to corresponding changes in mercury pressure operates to restore the power input to its approximate original value.
