types of LED retrofit lamps. Some IEC Requirements. With the exception of the US, which uses other standards, overvoltage transient surge testing per IEC 61000-4-5 is a global requirement for LED lighting assemblies. In addition, part of IEC61547, “Equipment for General Lighting Purposes” requires EMC immunity testing.
