MetroSpec Technology, the leading American manufacturer of custom LED light sources, announces a new addition to its FlexRad LED technology family. The BOC (BoardOnCoil) LED module is a perfect companion to the FacetCore radial lighting system. BoardOnCoil was developed to add directional light options for cylinders, pendants, sconces, and a wide variety of fixed and hanging fixtures. When used as an downlight, BOC fits well into a pendant because of its incredibly small size and weight and ability to be directed in a beam as tight as 10 degrees. Because of its novel open center coiled fin design, BOC allows air to pass freely through the center of a fixture, enabling ample cooling without any type of external protrusion from the fixture.
