UL IK & IP Rating Test for Lighting Products

Ratings that demonstrate the degree of Impact Protection (IK) and Ingress Protection (IP) are critical for street, roadway and other lighting products. IP ratings are required per IEC/EN 60598-2-3 for all roadway and street applications. IK ratings are required in specific applications when high impact glass provides protection for the enclosed lamp.

IEC 62262 specifies the way enclosures should be tested for IK ratings which are defined as the level of protection the enclosures provided against external mechanical impacts. IEC 60598-1 (IEC 60529) specifies the test method used to classify and rate the degree of protection an enclosure provides against intrusion of various sized solid objects from fingers and hands to fine dust and the protection against water intrusion from falling drops to a high pressure water jet.
IEC 60598-2-3 is the International Standard for Luminaires for Road and Street Lighting.

UL offers complete testing and certification services for street and roadway luminaires to IEC 60598-2-3

IK ratings are defined as IKXX, where “XX” is a number from 00 to 10 indicating the degrees of protection provided by electrical enclosures (including luminaires) against external mechanical impacts. The IK rating scale identifies the ability of an enclosure to resist impact energy levels measured in joules (J). IEC 62262 specifies how the enclosure must be mounted for testing, the atmospheric conditions required, the quantity and distribution of the test impacts and the impact hammer to be used for each level of IK rating.

IP ratings are defined as IPXX where the first X indicates the degree of protection against solid objects and the second X indicates the degrees of protection against water. A luminaire or lighting component with a rating of IP66 is dust-tight and protected against powerful water jets as described in IEC 60598-1 (IEC 60529).

Which IP rating products should we choose?

For indoor and outdoor LED lights, they come with different Ingress Protection (IP) ratings. An IP rating of LED light is the measurement of protection that LED light will have against liquid (water) and solid (dirt, dust etc.) objects. There are two numbers in the IP rating,The first number (0 to 6), in an solid IP rating. It shows the resistance against solid objects. The second number (0 to 8) implies the protection against water.

Now Let’s have a look at different IP ratings to get an idea of how they work. And different IP rating offer different protection against solids and liquids.

IP67 Rating LED lighting products

IP67 LED lights ratings give complete protection against solid and water. They are similar to IP65 and and IP64. The protection against liquids is same. However,LED lights with this rating are much more resistant to water as compared IP65. Water will have no effect on LED light even if it is immersed in water of the depth of 1m.

The most common waterproof LED lights are IP65 LED lights. They provides maximum protection against solid particles and a good amount of resistance against liquid particles as well. They can be fit to use for both in domestic and commercial purposes. However, if you are looking for use the lights in such a place where there is a risk of water, or need the ability to hose lights off then you need to choose LED Waterproof lights.

IP65 Rating LED lighting:

These lights are perfect for domestic and commercial use. IP65 rating gives complete protection against foreign bodies and water jets. Water disposed of by a nozzle of 6.3mm will have no damaging effect on LED light.

When you are purchasing an outdoor lighting fixture it should be IP65 rated. This includes things like LED Vapor tight and LED wet location fixture.

IP64 Rating LED lights

As you know see, the first digit in this IP rating is 6. It also gives a strong protection against the solid objects. It is not possible for any solid particle (dust, dirt etc) to affect the LED light. The second digit, 4, implies that the LED provides protection against splashing water only.

By definition this is the highest rating of most LED corn Light Bulb can get. That is because the bulb will always have to screw into a base and that base cannot be sealed. But as most LED corn lights are used in the lighting fixtures,IP64 is enough.

IP65 Rating LED lighting

LED lights with IP54 provide a complete dust protection. However, for liquids, it gives a protection against splashing water only. This will be common in basic led light bulbs and indoor fixtures.

IP40 Rating LED lighting

IP40 LED lights are normally used in an enclosed fixtures or indoor. An IP40 LED light should never be outdoors unless the fixture is sealed. It is usually fine indoors unless it’s an area of high humidity or other harsh conditions.  A lot of indoor LED Lights, LED retrofit kits and other fixtures fall in this category.
