Optics,  Thermals,  Electronics,  CAD -  Domestic & Off-Shore Fab Coordination

    Here you've found thirty years of experience in product development and manufacturing, with fifteen of those years in electro-optic design of LED systems for the outdoor environment.  LED traffic signals and Changeable Message Signs (CMS) pioneered environmental, thermal, optical and driver requirements for LEDs.  That Industry helped make LEDs what they are today. 

Highlights of past and present...  for your future:
  • Custom Injection Molded Lenses and Coupler Designs -  Refractive and TIR
  • Reflective Sheeting or Metalized Polycarbonate Reflectors
  • Die Cast & Extruded Housing Designs
  • 1%  -  100% Control with Conventional Dimmers
  • Light Guide Drivers,  Display Case  and  Cove Lighting
  • LED Border Lighting      (Replaces Neon)
  • Interior  &  Exterior,   Garage  &  Streetlight Luminaires
  • Refrigerated Case Lighting
  • Billboard Luminaires
  • LED Track Lights,  1600 Lumen,  12°  &  50°  Beam
  • Custom and OEM Light Engines

    Rest assured, the correct and incorrect practices are well established.  Here and now from a single source, you get the proven science and experience to make your product an Industry leader in solid state illumination.
