I can’t find the total length and height of this ET2 Starburst Modern / Contemporary Pendant Light – E20114-78. The only height given seems to be for the glass balls not the overall height from ceiling to glass balls.
The 12” would be the overall in width meaning from one side of the “first” shade to the other. Also the 6” in height is in reference to each individual globe from the very bottom up to the beginning of the socket. The round piece shown attached to the globe right “before” the beginning of the chrome fitting leading to the cord.
