GMS-1800 goniophotometer is a professional test device for the measurement of photometric parameters of various luminaires such as projecting lighting, road lighting and room lighting and its spatial luminous intensity distribution. The measurement parameters include spatial iso-intensity curve, intensity distribution curve of each section (shown with rectangular coordinate system or polar coordinate system), plane iso-illuminance distribution curve, luminance limitation curve, lamp efficiency, glare grade, effective luminous angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux, effective luminous flux,utilization factor and electric parameters (power, power factor, voltage and current) etc.



  • Match the requirements of IEC & relative national standards;
  • Rotating luminaires, reaching many measurement ways such as B-β, A-α and C-γ;
  • Compact structure, divided by double pillars or single pillar, easy for installing FL, down lamps,flood lighting etc;
