The ingress protection rating of an Explosion Proof Floodlight is a measure of how well the light's enclosure protects the internal components from the entry of solid objects and liquids. This rating is specified by the International Electrotechnical Commission (IEC) in their IEC 60529 standard. The rating consists of two digits, where the first digit represents the protection against solids while the second digit represents protection against liquids.

For Explosion Proof Floodlights, the minimum ingress protection rating is IP65. This means that the fixture is protected against dust and low-pressure water jets from any direction. However, many manufacturers provide higher protection ratings, such as IP67 or even IP68, which means that the lights are protected against immersion in water for long periods.
