Abstract: A modular light fixture has a track suspended from cables attached to a ceiling. The cables are attached to a coupler that can slide along the track and affix to a plurality of positions continuously along the track. The modular light fixture also includes one or more geometric profiles attached to the track. The geometric profiles contain a light source that illuminates through the geometric profiles. A spacer has the same external dimension as the geometric profiles and is made of the same material. The spacer couples two geometric profiles together seamlessly and without leaking any light between the geometric profiles and the spacer. The spacer may be shaped and sized to enable different connection angles between geometric profiles.
