This lamp focus knob is used in the lamp burner assembly of Source Four ERS fixtures. This inner knob is used to adjust between a peak or flat field (Z), part of the lamp focus mechanism which orients the lamp in the correct direction. While we use the name lamp burner, it is also called a socket cap, burnbase or burn base.
