The concept of "Class P" overheating protection type is derived from the "UL935 fluorescent lamp ballast" standard. Now the derivative "Class P" LED driver certification scheme can make the structure and rating of the driver more standardized.

The plan defines the specifications for evaluating the structure and standardized testing of LED drivers. This standard requirement was formulated by the industry associations, and finally approved by the UL8750 standard group, and added to the upgraded version of "UL 8750 LED Lighting Equipment" .

Lighting manufacturers can choose parts from multiple sources based on factors such as cost and delivery speed, without resubmitting to UL for testing and certification. This can prevent the trouble caused by a single LED driver manufacturer's suspension of supply and help maintain the stability of the supply chain.

At the same time, the Class P certification program can also provide end users with a variety of power supply voltages, dimming and other functional application designs without incurring certification costs.
