MetroSpec Technology Launches FlexRad BoardOnCoil Minnie

MetroSpec Technology® has leveraged its novel FlexRad® BoardOnCoil (BOC) technology to create the BOC Minnie. This new geometry can be used for pendant downlights, spot lights, sconces, acrylic rod lighting, and a wide variety of single-sided and double-sided directional fixtures. At less than 35mm in diameter and under 20mm in depth (including optic and heat sink), this light source is extremely compact. Powered up to 5 watts and capable of over 160 lumens per watt, the module is entirely self-cooled, requiring no separate heat sink.

Its extreme power-to-size ratio is enabled by direct bonding of a copper coil and a clear path of air flow through the center of the assembly. The assembly with optics weighs less than 20 grams. Available in almost every color and color temperature, as well as a variety of LED types. The BOC Minnie fits neatly into, or allows the miniaturization of, a variety of light fixtures.

Because of its open center coiled fin design, BOC Minnie allows air to freely pass through for self cooling without any kind of external protrusion, said Vic Holec, GM and Founder at MetroSpec Technology. This makes it perfect for mounting in cylinders, pendants, or sconces - without making tradeoffs. With an optic, light can be focused to as little as a 9 degree beam angle.

BoardOnCoil Minnie may be optionally ordered with lenses and provided with wires included. To facilitate this complete package, MetroSpec has partnered with Khatod® - Optical Solutions for LED Lighting. Khatod is a long standing, trusted manufacturer of quality optical solutions for major LEDs. MetroSpec Technology and Khatod will be exhibiting at LEDucation March 7- 8 in NYC. Stop by their booths to check out the award-winning products and latest innovations.

MetroSpec continues to invent new light sources that enable light fixture manufacturers to efficiently build light fixture forms simply, with less materials, cost and labor. The BoardOnCoil family of LED light sources is an excellent example. BOC goes in a different direction than conventional COB designs. The BOC is flat, very light, and extremely powerful - perfect for mounting in acrylic rods, cylinders, pendants, and sconces without making tradeoffs in size, appearance and structure.

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®, FacetCoreTM, Linear360®, Hashtag®, Dim2Tone®, and 4Tone®. In all of its forms, FlexRad is the most powerful, versatile, and most reliable LED light technology available.
