In recent times, LED lighting has become more popular for its numerous benefits compared to traditional lighting sources. LEDs offer efficiency, affordability, and a longer lifespan, making them a common selection for residential and commercial areas. Yet, when deciding on the ideal LED lighting fixtures, more should be taken into account than just luminescence and design. One major element to look at is the LED IP rating, showing the level of protection that the fixture offers against dust and water.


This article will go into detail about what LED IP rating is, its measuring, why it matters when selecting LED lighting fixtures, the various IP ratings, their meaning, and how to choose the ideal IP rating for individual requirements. At the end of this piece, you will have the know-how necessary to make informed choices when selecting LED lighting fixtures for any setting.


What is LED IP Rating?


In this segment, we will examine IP rating, its functions, and what it specifically implies when discussing LED lighting. We will take a comprehensive approach to help you become familiar with the fundamentals of LED IP rating, which will then pave the way for you to explore its more sophisticated aspects.


What is IP stand for?


Ingress Protection, often referred to by its acronym IP, is a standardized system of rating the effectiveness of an electronic device or its enclosure at resisting dust, water, and other foreign substances.


What is IP rating?


The IP rating is an expression of the amount of shielding a piece of electronic equipment has from foreign objects, water, and other external elements. The first number in the two-digit rating reflects the level of protection from solid elements such as dust, and the second figure denotes the degree of defense from liquids such as water.


What is LED IP rating?


The LED IP rating provides insight into the amount of protection that a given LED light has from foreign materials and liquids. This rating is critical for understanding if the light is suitable for a given area or not.


Solid Proof vs. Water Proof: IP rating chart


An IP rating chart is provided to easily comprehend the level of safeguard a lighting fixture provides against liquids and solids. This two-digit code explains the extent of protection. A straightforward description of the IP rating chart is given below


Solid Protection


  • * IP0X: No protection against solid objects
  • * IP1X: Protection against objects larger than 50mm
  • * IP2X: Protection against objects larger than 12.5mm
  • * IP3X: Protection against objects larger than 2.5mm
  • * IP4X: Protection against objects larger than 1mm
  • * IP5X: Dust-protected (limited ingress of dust)
  • * IP6X: Dust-tight (no ingress of dust)


Water Protection


  • *  PX0: No protection against water
  • * IPX1: Protection against water droplets falling onto it from a vertical position.
  • * IPX2: Protection against vertically falling drops of water when the enclosure is tilted at an angle of up to 15 degrees
  • * IPX3: Protection against sprayed water
  • * IPX4: Protection against splashed water from any direction
  • * IPX5: Protection against water jets (10-15 minutes, 3m jet distance, 30 kilopascals pressure)
  • * IPX6: Protection against powerful water jets from a 12.5mm nozzle
  • * IPX7: Protection against temporary immersion in water (1m deep, 30 minutes)
  • * IPX8: Protection against continuous immersion in water (1.5m, 30 minutes, freshwater)


How to choose the right IP rating for lighting


It's vital to carefully evaluate the intended application of lighting fixtures when determining the suitable IP rating. Depending on the surroundings, varying levels of defense from solid objects and fluids may be necessary.


For Indoor Use


The degree of protection needed for indoor lighting fixtures tends to be lower than for outdoor. To help you, here are some IP rating guidelines for lighting in interior spaces.:


IP20: This is the ideal choice for indoor environments with limited potential for dust and moisture, such as in residences and offices.


IP30:Suitable for use inside, especially in humid places like bathrooms, as it can withstand a small amount of dust and moisture.


IP40: Perfect for indoor use in areas prone to moderate dust and moisture levels, like kitchens or storage spaces.


For Outdoor Use


When selecting lighting fixtures for outdoor use, it is important to consider their protection against dust, water, and other environmental factors. The IP (Ingress Protection) rating system guides the recommended level of protection required in such scenarios. For instance, here are a few IP rating suggestions for outdoor lighting:


IP44: Suitable for outdoor use in areas not directly exposed to rain or harsh weather conditions, such as porches or covered patios.


IP65:Perfect for open-air areas that receive precipitation or hostile weather, making it an ideal option for illumining gardens or outdoor spaces.


IP67 or higher: Fixtures with an IP67 rating or above can be safely utilized in outdoor areas where they may be submerged in water for long durations, such as pools and fountains.


It is necessary to consider both the cost and the amount of protection needed when selecting a lighting fixture, as the higher IP ratings provide better protection but are usually more expensive.


The installation type must also be considered when determining the right IP rating for lighting. For instance, if the lighting fixture is in a difficult-to-access spot, like a tall ceiling, it might be worth investing in a higher IP rating to minimize maintenance and replacements.


While safety is the most important element to consider when picking an IP rating, the aesthetic features must be factored in too. Many higher IP ratings often come with less appealing and larger housing designs that are inappropriate for some spaces or particular styles. As such, a compromise may be necessary between the level of protection and the appearance of the luminaire.


It is critical to consider any relevant ordinances or codes that could affect your installation. In some cases, nearby building codes or rules could necessitate a definite lowest IP rating for lighting fixtures in specific settings.


Final Words


Knowing LED IP ratings is essential for selecting the most suitable lighting fixtures for various surroundings. While picking a rating, think about the amount of coverage desired for the area, the style of installation, and any corresponding codes or guidelines. By opting for the ideal IP rating, you can be confident that your light fixtures will give the proper protection and long-lasting durability for many years.
