Waterproof IP Rating

With so many IP ratings—IP44, IP65, IP67, IP68—it’s easy to get confused. Picking the wrong one could mean frequent failures, costly replacements, or unreliable lighting.

This guide will break down IP ratings, compare options, and help you choose the best one for your specific needs, ensuring long-lasting and efficient floodlighting.

Understanding IP Ratings

What Are IP Ratings and Why Do They Matter?

IP (Ingress Protection) ratings are an international standard that measures the degree of protection an electrical device, such as LED flood lights, has against solid particles (dust, dirt) and liquids (water, moisture).

For outdoor LED flood lights, selecting the correct IP rating ensures that the lights can withstand harsh environments, prevent damage, and last longer. Without proper protection, flood lights may suffer from water damage, dust accumulation, reduced brightness, or even electrical hazards.

Breaking Down IP Rating Format (e.g., IP65, IP67, IP68)

Each IP rating consists of two digits, such as IP65, IP67, IP68, where:

  • The first digit (0-6): Indicates protection against solid objects like dust and debris.
  • The second digit (0-9): Indicates protection against liquids, including rain, water jets, and immersion.
