IP44 vs IP65 vs IP67 Outdoor Lights: Quick Answer

IP44, IP65 and IP67 are not simply three versions of “waterproof outdoor lighting.”

They indicate different levels of protection provided by an electrical enclosure.

Under the IEC IP rating system, the first digit indicates protection against solid foreign objects, while the second digit indicates protection against water ingress. IP44 provides protection against solid objects of 1.0 mm and greater and against splashing water. IP65 is dust-tight and protected against water jets. IP67 is dust-tight and protected against the effects of temporary immersion in water.

For most professional outdoor lighting buyers, however, the key question is not:

“Which IP number is highest?”

The more useful question is:

“Which IP rating is appropriate for the way this product will actually be installed and used?”

A covered decorative string light, an exposed solar garden light, and a ground light installed close to wet soil do not face the same environmental conditions.

That is why importers, wholesalers, retailers and outdoor lighting brands should evaluate the IP rating together with the complete product structure.

What Does IP Rating Mean in Outdoor Lighting?

IP stands for Ingress Protection.

The IP Code is defined in IEC 60529 and is used to classify the degree of protection provided by electrical equipment enclosures against solid objects and liquids.

An IP code normally contains two digits.

For example:

IP65

The first digit is:

6 = protection against solid foreign objects / dust

The second digit is:

5 = protection against water

The two numbers therefore describe two different types of protection.

First Digit: Protection Against Solid Objects

The IEC scale for the first digit runs from 0 to 6.

At the upper end:

• 5 = dust-protected
• 6 = dust-tight

Second Digit: Protection Against Water

The second digit describes the degree of protection against water.

Examples relevant to outdoor lighting include:

• 4 = protection against splashing water
• 5 = protection against water jets
• 6 = protection against powerful water jets
• 7 = protection against the effects of temporary immersion
• 8 = protection against the effects of continuous immersion under specified conditions

These descriptions come from the IEC IP ratings guide.

IP44 Outdoor Lights: When Are They Suitable?

IP44 represents a lower level of environmental protection than IP65 or IP67, but that does not automatically make an IP44 product unsuitable.

An IP44 enclosure is protected against solid foreign objects of 1.0 mm and greater and against splashing water.

For outdoor lighting, IP44 may be considered for applications where the product is relatively protected from severe exposure.

Typical examples may include:

• covered patios
• covered balconies
• pergolas with overhead protection
• semi-protected café areas
• decorative outdoor areas
• temporary decorative installations

The important point is to evaluate the installation environment rather than treating all “outdoor” locations as identical.

LEDORA Product Example: G40 String Lights

In LEDORA’s current outdoor string light catalogue, standard plug-in G40 string lights are specified as IP44.

The range includes:

• G40 LED filament bulbs
• E12 sockets
• PVC cable
• warm white lighting
• US / UK / EU / AU plug options
• multiple string lengths
• connectable configurations

This illustrates an important sourcing principle:

The required IP rating should match the product’s intended application and construction, not simply a marketing preference for the highest possible number.

IP65 Outdoor Lights: A Common Choice for Exposed Outdoor Applications

IP65 represents a significant step up in enclosure protection.

According to the IEC rating system:

6 = dust-tight

and

5 = protected against water jets.

This makes IP65 a common specification to evaluate for products that may experience more direct outdoor exposure.

Possible applications include:

• open patios
• outdoor restaurants
• garden lighting
• solar garden lights
• outdoor decorative lighting
• wall lights
• pathway lighting
• certain outdoor string light installations

However, IP65 still needs to be considered together with how the complete lighting system is constructed and installed.

LEDORA Product Example: S14 Outdoor String Lights

LEDORA’s current plug-in S14 outdoor string light range is specified as IP65.

Available configurations include:

• S14 LED filament bulbs
• E26/E27 sockets
• PVC or rubber cable options
• 1W / 2W bulbs
• warm white
• US / UK / EU / AU plugs
• multiple lengths and socket quantities
• connectable designs

This makes the S14 range useful for buyers developing outdoor patio and hospitality lighting programs where a more substantial bulb style and higher enclosure protection are required.

IP67 Outdoor Lights: What Does IP67 Actually Mean?

IP67 is frequently described in marketing materials as “waterproof.”

Professional buyers should use more precise terminology.

Under the IEC IP code:

6 = dust-tight

and

7 = protected against the effects of temporary immersion in water.

This is an important distinction.

IP67 Does Not Automatically Mean “Permanent Underwater Use”

A common sourcing misunderstanding is:

“If IP67 can handle immersion, it can stay underwater permanently.”

That is not what the IP7 definition means.

The IEC guide distinguishes temporary immersion at level 7 from continuous immersion at level 8.

Therefore, an importer should never interpret IP67 as a blanket guarantee for permanent underwater installation.

The actual product design, manufacturer’s test conditions, installation requirements and intended application should all be checked.

What About IP68 Outdoor Lights?

IP68 goes beyond IP67 in the water-protection classification.

In the IEC guide, the second numeral 8 refers to protection against the effects of continuous immersion in water, under the applicable specified conditions.

This does not mean every IP68 product has identical immersion conditions.

Professional buyers should obtain the relevant product and testing information rather than making assumptions based only on the number.

LEDORA Product Example: Solar Ground Lights

Some models in LEDORA’s current Solar Ground Lights catalogue are specified as IP68.

For example, certain solar ground light configurations combine:

• solar charging
• stainless steel and ABS construction
• rechargeable batteries
• automatic light-control functions
• ground-level installation
• IP68 specification

Ground lights are an example of a product category where buyers may need to pay particular attention to exposure from:

• rain
• wet soil
• ground splash
• accumulated surface water
• irrigation
• drainage conditions

For these products, enclosure protection becomes an especially important part of sourcing and product evaluation.

IP44 vs IP65 vs IP67: Side-by-Side Comparison

IP Rating	Solid Protection	Water Protection	Typical Outdoor Evaluation
IP44	Objects ≥1.0 mm	Splashing water	Covered or semi-protected decorative locations
IP65	Dust-tight	Water jets	More exposed outdoor lighting
IP67	Dust-tight	Temporary immersion	Applications needing greater protection from water exposure
IP68	Dust-tight	Continuous immersion under specified conditions	Specialized products where immersion protection is required

The protection descriptions above follow the IEC IP rating system.

The application column is a practical sourcing guide, not a substitute for project-specific electrical, safety or installation requirements.

Which IP Rating Should You Choose for Outdoor Lights?

There is no single IP rating that is automatically correct for every outdoor lighting product.

A useful starting framework is:

Application	Suggested Starting Point for Evaluation
Covered balcony	IP44
Covered café patio	IP44 / IP54
Open patio	IP65
Open garden lighting	IP65
Solar garden light	IP65 or above depending on design
Outdoor wall light	IP54 / IP65 depending on exposure
Outdoor string lights	IP44–IP65 depending on construction and exposure
Ground lights	IP67 / IP68 depending on design and installation
Exposed outdoor flood light	IP65 or above depending on project requirements

These are sourcing considerations rather than universal installation rules.

Buyers should always confirm the requirements of the destination market and actual project.

Is IP65 Always Better Than IP44?

Not necessarily.

A higher IP rating indicates a higher degree of protection under the corresponding test classification, but this does not automatically mean the product is commercially better for every application.

For example, buyers also need to consider:

• target retail price
• product weight
• construction
• installation environment
• intended lifespan
• application
• cable specification
• plug system
• compliance requirements

If a decorative product is intended for a protected installation, an appropriately designed IP44 product may fit that program.

If the product will be installed in a more exposed environment, the buyer may prefer an IP65 configuration.

The correct specification should follow the intended use.

Don’t Evaluate Outdoor Lights by IP Rating Alone

This is one of the most important points for professional lighting buyers.

An IP number describes enclosure protection under specified test conditions.

It does not tell you everything about the quality of an outdoor lighting product.

The IEC itself notes that an IP rating indicates how a device or enclosure was tested rather than automatically defining every real-world condition in which it can be used.

A professional buyer should therefore inspect the complete lighting system.

1. Cable Entry Points

Check where the cable enters:

• lamp housing
• controller
• socket
• solar panel housing
• battery compartment

These locations can become potential ingress points if the structure is poorly designed.

2. Socket Construction

For outdoor string lights, examine:

• socket housing
• bulb connection
• seals
• cable-to-socket connection
• hanging construction

The IP rating of one component should not automatically be assumed to describe every part of the complete string-light installation.

3. Connectors

For connectable lighting systems, review:

• male/female connectors
• sealing structure
• connector caps
• installation method

4. Plug and Power Supply

The light string may be rated for outdoor exposure while a plug, adapter, controller or connection point has different installation requirements.

Buyers should confirm the complete system specification.

5. Battery Compartment

For solar lights, the battery compartment and housing construction are important because repeated moisture ingress can affect long-term product reliability.

6. Solar Panel Connection

Solar garden lights often combine several elements:

solar panel → cable → controller → battery → LED

Each connection should be considered during product evaluation.

7. Gaskets and Sealing Structure

Check whether the product relies on:

• silicone seals
• rubber gaskets
• ultrasonic welding
• screws
• molded enclosure design
• other sealing methods

8. Installation Design

Even a well-protected enclosure can perform poorly if installed incorrectly.

Installation angle, drainage and cable position can all matter.

What Should Importers Ask Before Ordering Outdoor Lights?

When requesting a quotation, buyers should not simply write:

“Please quote your waterproof outdoor lights.”

Instead, provide a complete requirement.

Compliance Requirements

The required compliance documentation depends on product type and destination market.

Buyers should confirm the applicable requirements before production.

How Should B2B Buyers Verify an IP Rating?

For professional sourcing, do not rely only on an IP number printed on a quotation.

Depending on the size and risk level of the order, buyers may want to review:

1. product specification
2. applicable test report
3. model number
4. test scope
5. relevant product construction
6. sample structure
7. production consistency
8. inspection requirements

A test report for one product should not automatically be assumed to apply to a substantially different model or construction.

For OEM/ODM projects, this becomes especially important if the buyer changes:

• housing
• cable
• connector
• socket
• battery compartment
• solar panel structure
• dimensions
• sealing method

Changes to a product can affect its final technical characteristics.

Why IP Rating Matters for OEM and ODM Projects

OEM outdoor lighting development often involves more than changing a logo.

A buyer may request:

• different housing materials
• new dimensions
• different cables
• custom connectors
• modified battery capacity
• alternative solar panels
• new packaging
• new mounting systems

From a sourcing perspective, buyers should understand that significant structural changes may require the product’s performance and relevant testing to be reconsidered.

Therefore, when developing an OEM outdoor light, the workflow should be:

Define Application → Confirm Product Structure → Confirm Target IP Requirement → Develop Sample → Test → Approve → Bulk Production

This approach is more reliable than selecting an IP number only after product development has been completed.

IP Rating Checklist for Outdoor Lighting Buyers

Before approving an outdoor lighting order, review the following:

• What is the actual installation environment?
• Will the product be covered or fully exposed?
• Is standing water possible?
• What IP rating is required?
• Does the rating apply to the relevant enclosure/product?
• Has the product structure changed from the tested version?
• Are cable entry points adequately designed?
• Are connectors properly protected?
• Is the plug or adapter suitable for the installation method?
• Is the battery compartment properly protected?
• Has the sample been inspected?
• Is relevant testing documentation available when required?
• Will bulk production use the same approved structure?
• Is final quality inspection included?

Frequently Asked Questions

Is IP44 suitable for outdoor use?

IP44 provides protection against solid foreign objects of 1.0 mm and greater and against splashing water under the IEC IP rating system.

Whether it is appropriate depends on the actual installation. It may be considered for some covered or semi-protected outdoor decorative applications, while more exposed environments may require a higher level of protection.

Is IP65 waterproof enough for rain?

IP65 means the enclosure is dust-tight and protected against water jets under the corresponding IEC classification.

However, buyers should avoid reducing product selection to the word “waterproof.” Installation environment, complete product structure, connectors, plugs and other components should also be evaluated.

Is IP67 better than IP65?

IP67 provides a different and higher level of water-ingress protection than IP65 in the IEC rating sequence: IP65 relates to water jets, while IP67 relates to temporary immersion.

That does not mean IP67 is necessary for every outdoor lighting application. The correct rating depends on the intended use.

Can IP67 lights be permanently submerged in water?

IP67 refers to protection against the effects of temporary immersion. IEC distinguishes this from level 8, which relates to continuous immersion under specified conditions.

Therefore, IP67 should not automatically be interpreted as approval for permanent underwater installation.

What IP rating is best for solar garden lights?

There is no single universal rating for every solar garden light.

For exposed garden applications, buyers commonly evaluate higher outdoor-protection configurations such as IP65 or above depending on the design, installation and project requirements.

The complete housing, battery compartment, solar panel connection and sealing structure should also be evaluated.

What IP rating should outdoor string lights have?

It depends on the installation.

LEDORA’s current range provides a useful example of product differentiation: standard plug-in G40 string lights are specified as IP44, while current plug-in S14 string lights are specified as IP65.

The appropriate product should be selected according to exposure, target application and construction.

Is IP68 necessary for solar ground lights?

Not every ground-light application automatically requires IP68.

However, ground lights can face challenging conditions such as wet soil, rain splash, irrigation and accumulated water.

Some LEDORA Solar Ground Light models are currently specified as IP68, illustrating how higher enclosure protection can be used for this product category.

Does a higher IP rating mean a higher-quality outdoor light?

Not by itself.

IP rating describes a specific aspect of enclosure protection.

Overall lighting quality can also depend on:

• materials
• LEDs
• battery quality
• solar panel performance
• cable construction
• electrical design
• thermal management
• manufacturing consistency
• quality control

Professional buyers should evaluate the whole product.

Should importers verify IP ratings before bulk production?

For orders where the IP rating is an important technical or commercial requirement, buyers should confirm the product specification and relevant supporting documentation before approving bulk production.

This is especially important when an OEM/ODM project changes the product’s enclosure or sealing structure.

Conclusion

Choosing between IP44, IP65 and IP67 outdoor lights should not be reduced to selecting the highest number.

Each rating represents a different degree of enclosure protection.

In practical B2B sourcing:

IP44 can fit certain covered or semi-protected decorative applications.

IP65 provides dust-tight protection and protection against water jets and is commonly evaluated for more exposed outdoor lighting.

IP67 adds protection against the effects of temporary immersion.

IP68 relates to continuous immersion protection under specified conditions and may be relevant for specialized product designs.

The most important purchasing principle is:

Match the IP rating to the actual application, and evaluate the complete lighting system rather than relying on one specification alone.

For importers, wholesalers, retailers and outdoor lighting brands, this approach can improve product selection, reduce specification misunderstandings and support more reliable OEM/ODM development.
