MetroSpec Technology introduces FlexRad® FacetCore Spline technology

FacetCore Spline is a high performance shape enabling LED light sources for curved light fixtures in architectural lighting.

ST. PAUL, MN, June 7, 2022 - MetroSpec Technology, the leading American manufacturer of custom FlexRad LED light sources, is proud to introduce yet another shape enabling innovation for Architectural Lighting. FacetCore™ Spline LED light sources provide radial light for curved light fixtures that need a completely seamless appearance. FacetCore Spline does not need an extrusion or a bent sheet metal undercarriage – it slides simply and easily (like a glove) over a pre-shaped rod or tube, taking on the shape of the fixture. MetroSpec’s breakthrough FlexRad technology provides design freedom that is unmatched in the industry. This unique, patented technology is innovative, reliable, and customizable to any shape and size. The Spline enables this technology to be used in curved fixtures.

“FacetCore Spline is part of a continuing series of labor saving and shape enabling products that began with our core Cut2Fit system in 2009. At that time, MetroSpec offered the ONLY trim-to-fit flexible LED light source in the market. We have been enabling light fixture manufacturers with novel technologies ever since. FlexRad is unique in that it is always trimmable and enables higher brightness than our competitors. Spline is actually a combination of three of our FlexRad technologies: FacetCore, Linear360 and Dim2Tone. It comes in a pre-assembled form with wires or connectors, and is still trim-to-fit, resulting in no material waste. We make production of LED light fixtures easier for our customers with built-in ease of assembly and labor savings, ultimately resulting in lower overall costs,” said Vic Holec, General Manager and Founder of MetroSpec Technology.

FlexRad includes a variety of technologies that allow fixture manufacturers to fill almost any shape with light. The novel applications of FlexRad also include Cut2Fit, Dually, Linear360, Hashtag, BoardOnCoil, Dim2Tone, and 4Tone. In all of its forms, FlexRad is the most powerful, versatile, and most reliable LED light technology available. As with all MetroSpec products, FacetCore Spline can be customized to perfectly fit all customer requirements.
