Abstract
A mounting assembly for a light bulb includes a soft start-up circuit as well as a DC-to-AC converter in order to prolong bulb life. In addition, the mounting assembly includes a removable socket to facilitate changing the bulb. When the socket is rotated from an "engaged" position for removal, an interlock causes power to be interrupted at a remote location from the mounting assembly. In addition, conducting portions of the mounting assembly are remotely located to reduce the possibility of accidental contact during socket installation and removal.
