For the Goniophotometer, there have two different models, one is LSG-2000 Goniophotometer with Rotating Mirror or LSG-1900 Moving Detector Goniophotometer, this kind of goniophotometer that means luminaires keep stable, the mirror is moving according to the light source of luminaires, this test way is receoomend by LM-79 Clause 3.1 and CIE, CE, it have higher accuracy and better stability; another is LSG-1800B/LSG-1600B High Precision Rotation Luminaires Goniophotometer that means the luminaires is rotating, this test way is recommend by CIE 127: 1997, it have smaller dark room size than LSG-2000. If you interesting in this instrument, according to your maximun luminaires size and budget, you can consider this one; For the Spectrometer, as we know, the spectrometer is working together with integrating sphere, standard light source and other instrument, the integrating sphere provide the test environment, the spectrometer do the calibrate and have a test report last, according to different lamp, there have two models, if you just want test LED, LED luminaires, you can reference LPCE-2(LMS-9000A) High Precision Spectroradiometer & Integrating Sphere; if you also need test CFL, HID lamp etc, you can reference LPCE-1 Spectrophotometer & Integrating Sphere Test System, thanks!
