While consumers often evaluate lights based on typical performance metrics, there's one specification unrelated to light efficiency that could be crucial to preserving your investment and ensuring visibility in the dark. The IP rating becomes especially important when facing harsh weather, crossing rivers, or enduring dust storms. Lights and various electrical devices are commonly installed on rooftops, bull bars, trailers, and other surfaces that encounter the elements every day.

Initially, the acronym "IP" stands for "Ingress Protection." It indicates how well an electrical product, like an LED light bar or work lamp, is shielded from solid and liquid particles. When you notice 'IP' on packaging or a product, it signifies that the item is designed to prevent the intrusion of fluids, dust, and other particles, which could otherwise harm the internal components or compromise its performance.

If a manufacturer provides legitimate IP ratings, it indicates they've rigorously tested the equipment to verify its level of ingress protection. You might find these ratings conspicuously missing from cheap knock-offs in bargain stores.

Let's delve into the numbers! An IP rating is usually accompanied by numerical and sometimes letter combinations, such as IP68. The number isn't simply 68; it's composed of two distinct figures, 6 and 8. Each of these digits holds significant meaning, providing specific details about the protection level.

The first digit indicates protection against the entry of solid objects, such as dust and small stones, while the second digit specifies the level of protection against the penetration of liquids like water.

An IP00 rating indicates that the product offers no resistance against the ingress of solids or liquids, which could lead to damage. Owning such a product is not advisable for activities like boating or off-road driving. On the other hand, an IP04 rating means the product isn't protected against solid intrusions, but it is capable of withstanding exposure to water spray.

Having two ratings might appear unusual, but it signifies that the product has undergone two separate tests. Achieving the highest rating, IP69K, doesn't imply it has passed every possible test below that level.

Referring to the IP chart, it's evident that while both ratings offer excellent protection against solid particles, the product is designed to endure continuous immersion in water according to the manufacturer's specifications. Additionally, it is safeguarded against high-pressure, high-temperature spray downs at close range.
