Abstract
A protective sleeve of quartz surrounding a metal halide arc tube is fixed to upright portions of a frame by means of retaining rings. The frame has lower ends formed with coils fitted over the glass stem in an interference fit, thereby insulating the frame from the electrical leads sealed in the stem. An intermediate portion of the frame fits closely in the opposite end of the lamp to stabilize the burner assembly and shield.
