It is important when installing any lighting products that the IP rating is suitable for the application. In a nutshell, ingress protection (IP) is an international standard for classifying the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water.
LED tapes, being one of the most popular LED lighting products on the market, are generally available in four IP ratings explained below. Ensuring that you use the correct level of protection will minimize safety issues and premature failure of the luminaires. For example, installing an IP20 LED tape in an external environment will result in the product failing in a very short time as the copper of the FPC, the resistors, and the LED chips are fully exposed to the elements. The same applies to any other electrical products such as LED drivers, controllers, receivers, decoders, etc.
Any electronics that are not IP rated for external use must be situated inside a suitable IP-rated enclosure to provide adequate protection.
