A waterproof LED strip light is a linear array of LED packages which are assembled on a flexible printed circuit board, with the entire assembly having a minimum ingress protection (IP) rating of IP65. An IP rating refers to the degree of protection provided by an electronic or electrical enclosure against the intrusion of external dust, fluid, or other objects that may pass through into the product. The first digit indicates protection against solid objects. The second digit identifies the level of liquid protection. The larger the value of each digit, the greater the protection is. Depending on the application, waterproof LED strips can be sealed to an IP65, IP67, or IP68 rating. All products are hermetically sealed for the highest level of protection against solids (dust tight) but the level of protection against liquids varies.
