Everything you need to know about IK-Value for LED lighting

If you're looking for quality LED lighting for your home or business, you've probably come across the term "IK-value." But what does this actually mean? In this article, we'll explain what IK value is, the different values and why it's important when choosing LED lighting.

What is IK value?

The IK value is a measure of the impact resistance of an electrical device, such as LED luminaires. It indicates the extent to which a device can withstand external mechanical shocks. In other words, it tells you how well the light fixture can withstand impacts such as knocks, falls or vandalism.

Different IK values

The IK value is shown on a scale from IK00 to IK10, with IK00 indicating the lowest and IK10 the highest impact resistance. The higher the IK value, the more resistant the lighting is to external impacts.

IK00 - No impact resistance: Lighting with an IK00 rating provides no protection against external impacts and is highly susceptible to damage.

IK01 to IK04 - Low impact resistance: Lighting with an IK01 to IK04 rating provides limited protection against light impacts, but can still be easily damaged.

IK05 and IK06 - Medium impact resistance: Lighting with an IK05 or IK06 rating is more resistant to impact and can withstand some degree of impact. It is suitable for use in environments where there is a chance of minor damage.

IK07 and IK08 - High Impact Resistance: Lighting with an IK07 or IK08 rating is highly resistant to impact and can withstand high levels of impact. This makes it ideal for applications where vandalism or harsh conditions are likely.

IK09 and IK10 - Very high impact resistance: Lighting with an IK09 or IK10 rating offers the highest impact resistance. It can withstand severe impacts and vandalism, making it suitable for use in high-risk environments.

Why is the IK value important?

Knowing the IK value is essential when selecting LED lighting fixtures, especially if you plan to install them in places where physical damage may occur. Choosing lighting with the right IK value will help ensure the durability and longevity of your lighting fixtures. It also helps minimize the cost and inconvenience of replacing damaged fixtures.

Benefits of LED lighting with a high IK value

LED lighting with a high IK value offers several advantages. First, it extends the life of lighting fixtures by making them resistant to shocks and impacts. This reduces the frequency of replacement and associated costs.

In addition, a higher IK value provides a higher degree of safety. In environments where vandalism, rough handling or potential impacts play a role, LED lighting with a high IK value offers a reliable solution. This is especially relevant for public areas, parking lots, sports facilities and industrial environments.

Tips for choosing the right IK value for your LED lighting

When selecting LED lighting with the right IK value, it is important to consider the specific environment and intended use. Consider the following factors:

  • Location: Identify whether the lighting will be used indoors or outdoors. Outdoors, the risk of vandalism and impacts is often greater.
  • Risk of impacts: Assess the risk of potential impacts, such as near doors, stairs, parking lots or playgrounds.
  • Safety regulations: Check if specific safety regulations apply to your application. Some industries require specific IK values to meet applicable standards.

By considering these factors, you can determine the appropriate IK value and ensure that your LED lighting is suitable for the intended application.


The IK value is an important factor to consider when choosing LED lighting. It indicates the extent to which the lighting can withstand external shocks and impacts. By selecting the right IK value, you can ensure the durability, safety and reliability of your lighting solutions.
