What is the difference between UL Recognized vs UL Listed?

The main difference between UL Listed and UL Recognized is that UL Listed products have undergone comprehensive testing and certification by UL, whereas UL Recognized products have only been tested as components or materials.

Another key difference is that UL Listed products are considered to be of higher quality and safer than UL Recognized products. This is because UL Listed products have undergone more rigorous testing and certification processes.

In terms of applications, UL Listed products are typically used in products that have a higher risk of danger, such as electrical appliances, whereas UL Recognized products are used in products that have a lower risk of danger, such as electronic devices.
