Lighting EMC Testing Services

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate as required in its electromagnetic environment without causing intolerable electromagnetic interference (EMI) to any equipment in its environment. EMC includes two aspects:

1. On one hand, the electromagnetic interference generated by the device during normal operation must not exceed a certain limit (EMI).

2. On the other hand, the device should have a certain level of immunity to electromagnetic interference existing in the environment, referred to as electromagnetic sensitivity (EMS).

Except for incandescent lamps (including all incandescent lamps such as halogen lamps) without dimming devices or electronic switches, which are exempt from emc testing, other lighting fixtures must undergo emc testing. Lighting fixtures without electronic devices are exempt from EMS testing.

Lighting fixtures in the United States must comply with the requirements of fcc part 18 and undergo the Declaration of Conformity (DoC) certification.
