The IP (Ingress Protection) Rating

The IP (Ingress Protection) Rating

Understanding IP Ratings for Illumination

IP (Ingress Protection) ratings indicate a light fixture's resistance to dirt and water ingress, essential for durability and safety in various environments. Higher ratings denote greater protection against external elements, ensuring reliable performance and longevity. 

With the right IP rating, your lighting fixtures can thrive indoors or outdoors, regardless of moisture or dust levels.

Comprising two digits, the IP rating's first digit signifies defense against solid objects, while the second digit denotes liquid protection. Higher digits signify enhanced protection. The IP level encompasses waterproofing and defense against dust and solid particles. 


Typically, indoor lighting fixtures have an IP20 rating, adequate for most indoor settings. Ratings ranging from IP44 to IP65 are suitable for indoor and outdoor use if installed in sheltered areas and shielded from severe weather. 

Level of protection

Lower IP ratings, typically below IP44, are designed for indoor settings with minimal dust or water exposure, such as living rooms or bedrooms. Most indoor fixtures boast an IP20 rating, suitable for common indoor needs. 


Ratings falling between IP44 and IP65 are versatile, fitting for both indoor and outdoor use if placed in sheltered areas away from severe weather. 


Higher IP-rated fixtures are ideal for harsh weather conditions. For environments prone to dust or liquid exposure, opting for a high IP rating ensures superior protection. 


Fixtures with IP65 and above are waterproof, suitable for indoor and outdoor applications. Common ratings like IP65 and IP66 provide enhanced protection, with IP65 lights enduring water projection and IP66 lights withstanding forceful water spray, though both should avoid submersion. 

Why are IP ratings required across industries?

IP ratings are essential for lighting products, especially LED luminaires, to ensure they meet necessary protection standards against environmental factors. These ratings determine the level of protection against dust and water ingress, crucial for maintaining functionality and safety. 


In commercial and industrial settings, selecting luminaires with appropriate IP ratings is vital to safeguard against potential hazards. Without adequate protection from dust, particles can infiltrate the luminaire's power supply cavity, leading to corrosion, damage, and even fire hazards. Similarly, water ingress can result in short circuits within the luminaire's internal circuitry, affecting both functionality and safety. Additionally, water intrusion can compromise the efficiency of LED luminaires and ultimately impact lighting performance. 


Industries like manufacturing and factories, known for their high dust levels, pose additional risks, as dust particles encountering electrically charged parts of LED luminaires can cause explosions. Therefore, ensuring LED luminaires have suitable IP ratings is crucial for longevity, efficiency, and safety in various environments.
