SQS FF02 high-voltage LED light engins adopt a proprietary and patented technology including driving scheme which allows LEDs to be driven from 230 V AC directly. The FF02 engines contain mostly surface mounted devices and high-voltage LEDs mounted in the form of bare chips directly attached to the substrate (COB technology) to minimize light engine dimensions and improve thermal management. There are no components that would significantly affect reliability of the LED light engine, e.g. electrolytic capacitors. The light engine is certified according to CE standards.

SQS FF02 LED light engins offer high light efficacy together with high reliability, uniformity, and efficiency in a compact all-solid-state package.


  • long lifetime, high reliability, direct 230V AC power supply, no power converters, no electrolytic capacitors
  • environmentally friendly (RoHS compliant) – lead-free, no restricted substances
  • excellent thermal management – HV LED InGaN chips directly attached to metal core printed circuit board (MCPCB)
  • high lumen output, high light efficacy ^polished mirroring area for back reflections improving light output
  • CRI and CCT variability – luminophore compound customization
  • CCT binning according to ANSI NEMA ANSLG C78.377-2008 standard
  • vynikající teplotní management (Al MCPCB)
  • compact size
  • custom light distribution – wide range of lenses. Materials: silicon, glass, PMMA. Types: spherical, aspherical, TIR, Fresnel, symetrical, asymmetrical.


  • LED lighting fixtures
  • interior and exterior building lighting (residential and public)
  • interior and exterior industrial lighting
  • park and street lighting
