Rotation Luminaire Goniophotometer

LSG-1700 goniophotometer is an automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, HID luminaires, fluorescent lamps and so on.
