Lamp 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 to any device in its environment. 

EMC includes two requirements: on the one hand, it means that the electromagnetic interference caused by the equipment to the environment during normal operation cannot exceed a certain limit (EMI); on the other hand, it means that the electromagnetic interference existing in the environment of the equipment has A certain level of immunity, known as electromagnetic susceptibility (EMS).

Electromagnetic Compatibility (EMC) refers to the ability of a device or system to operate effectively within its electromagnetic environment without causing unacceptable electromagnetic interference (EMI) to other devices in that environment. EMC encompasses two main requirements:
  1. Electromagnetic Interference (EMI): The device must not emit electromagnetic interference that exceeds specified limits during normal operation.
  2. Electromagnetic Sensitivity (EMS): The device must be able to withstand a certain level of electromagnetic interference present in its environment, demonstrating sufficient immunity.
Exceptions and Requirements for Lighting Fixtures:
  • Incandescent Lamps: Incandescent lamps (including halogen lamps) that do not have dimmers or electronic switches do not require EMC testing.
  • Other Lighting Fixtures: All other lighting fixtures must undergo EMC testing. Fixtures without electronic devices are exempt from EMS testing.
In the United States, lighting fixtures and equipment must comply with the requirements of FCC Part 18 and must complete the Declaration of Conformity (DoC) certification.
