LSG-1950 is a CIE A-α goiophotometer. The photometer head keeps static and it faces to the sample under test while the sample is rotating around both horizontal axis and vertical axis. So the luminous intensity and illuminance of the lamp or luminaires can be tested. Fully meet the Final Report PC13050202 Oregon, ECE-R65, FMVSS108, GB13954 and GB 25991 Standards.

• A axis rotating angle: -180~180° and α axis rotating angle: -180~180°
• The accuracy of angle: 0.01°.  The resolution of angle: 0.001°
• Luminosity testing range: illuminance 0.001lx~99,999lx; Light intensity 1.0cd~107cd (detector)
• Accuracy of photometry: CIE Class A or Class L (option)
• Testing accuracy: 2% (Under Standard lamp); Stray light: less than 0.1%
