According to the requirements of CIE, IESNA and national standards, we have achieved testing methods as B-(B、A-a and C-y through rotating lamps. It is used to test the spatial light intensity distribution as well as variety luminosity parameter of indoor spotlight, cast light lamp and street light. It can work either with double arm or single arm.

Technical support features:
The main shaft and lamp shaft adopt the conductive slip ring with precious metal optical fiber point brush structure, which can run 360 degrees continuously without backlash for measurement. There is no need to rotate back and forth to prevent winding, and never winding;
Adopt a well-known brand of high-speed, high-torque, low-noise, low-vibration three-phase hybrid stepping motor;
It has a laser sight to make the center of the lamp under test coincide with the center of rotation of the rotating table;
Vertical axis rotation range: -180°~180° or 0°~360° rotation;
Horizontal axis rotation range: -180°~180° or 0°~360° rotation;
