Can LED Neon Signs Get Wet? Understanding IP67 and IP68 Waterproofing

LED neon signs have become increasingly popular for homes, businesses, weddings, events, and outdoor advertising. Their vibrant glow, energy efficiency, and customizable designs make them an excellent alternative to traditional glass neon.

One of the most common questions customers ask is:

Can LED neon signs get wet?

The answer depends on the sign's waterproof rating. While some LED neon signs are designed exclusively for indoor use, others are specifically engineered to withstand rain, moisture, and even temporary submersion in water.

In this guide, we'll explain how waterproof LED neon signs work, what IP67 and IP68 ratings mean, and how to choose the right waterproof level for your project.

Can LED Neon Signs Get Wet?

Yes, waterproof LED neon signs can get wet, but not all LED neon signs are waterproof.

Standard indoor LED neon signs typically feature exposed wiring, open connectors, and power supplies that are not protected against water. Exposure to rain or excessive moisture can damage the electronics and create safety risks.

For outdoor or wet environments, manufacturers use waterproof silicone encapsulation, sealed wiring, and specialized power components to protect the sign from water intrusion.

The key factor to check is the Ingress Protection (IP) rating.

What Is an IP Rating?

An IP (Ingress Protection) rating is an international standard that measures how well an electrical product is protected against:

• Solid particles (dust, dirt, debris)
• Liquids (water, rain, moisture)

The rating consists of two numbers:

IPXY

• X = protection against solids
• Y = protection against water

For LED neon signs, the most common waterproof ratings are IP67 and IP68.

Understanding IP67 Waterproof LED Neon Signs

What Does IP67 Mean?

IP67 indicates that the sign is:

• Completely protected against dust
• Protected against temporary water immersion up to 1 meter (3.3 feet) for 30 minutes

This level of protection makes IP67 LED neon signs suitable for most outdoor applications.

Best Uses for IP67 LED Neon Signs

• Storefront signage
• Outdoor business signs
• Patio décor
• Garden lighting
• Event signage
• Restaurant exteriors
• Wedding signs

Advantages of IP67 Signs

✔ Resistant to rain and snow

✔ Suitable for humid climates

✔ Durable outdoor performance

✔ Lower cost compared to higher waterproof ratings

Limitations

Although IP67 signs can withstand temporary immersion, they are not designed for continuous underwater use.

Understanding IP68 Waterproof LED Neon Signs

What Does IP68 Mean?

IP68 provides a higher level of water protection than IP67.

IP68-rated LED neon signs are:

• Completely dustproof
• Designed for continuous immersion in water under manufacturer-specified conditions

Because testing standards can vary, manufacturers may specify different immersion depths and durations.

Best Uses for IP68 LED Neon Signs

• Swimming pool areas
• Water features
• Fountains
• Marine applications
• Waterfront installations
• High-humidity environments

Advantages of IP68 Signs

✔ Maximum water resistance

✔ Suitable for extreme weather conditions

✔ Ideal for installations near water

✔ Long-term durability in challenging environments

Considerations

IP68 signs are generally:

• More expensive
• Heavier due to additional sealing materials
• More complex to manufacture

For most outdoor signage applications, IP67 is often sufficient.

IP67 vs IP68: Which Waterproof Rating Should You Choose?

Choose IP67 If:

• Your sign will be mounted outdoors
• It will be exposed to rain and weather
• You want reliable protection at a lower cost

Choose IP68 If:

• Your sign will be installed near water features
• It may experience prolonged water exposure
• Maximum waterproof performance is required

Are the Power Supply and Connectors Waterproof Too?

This is an important detail many buyers overlook.

Even if the LED neon sign itself is waterproof, the entire system is only as waterproof as its weakest component.

For outdoor installations, ensure that:

• The power adapter is outdoor-rated
• Connectors are waterproof
• Wiring junctions are sealed
• Cable entry points are protected

A waterproof sign paired with a non-waterproof power supply can still fail when exposed to moisture.

How to Maintain Waterproof LED Neon Signs

To maximize lifespan:

Regularly Inspect Seals

Check silicone edges and cable connections for damage or wear.

Avoid Physical Impact

Cracks in the waterproof housing can allow water to enter.

Clean Properly

Use a soft damp cloth to remove dirt and debris.

Avoid:

• Abrasive cleaners
• High-pressure washers
• Harsh chemicals

Protect Electrical Components

Mount power supplies inside weatherproof enclosures whenever possible.

How Long Do Waterproof LED Neon Signs Last?

High-quality waterproof LED neon signs typically last:

• 30,000–50,000+ hours
• Up to 5–10 years or more depending on usage conditions

Factors affecting lifespan include:

• Product quality
• Installation method
• Environmental exposure
• Power supply quality
• Maintenance practices

Because LED technology generates minimal heat, waterproof LED neon signs are generally safe for long-term operation, including overnight use.

Frequently Asked Questions

Can LED neon signs stay outside in the rain?

Yes, if the sign has an IP67 or IP68 waterproof rating and uses waterproof electrical components.

Can an indoor LED neon sign get wet?

No. Indoor signs are not designed for water exposure and may be damaged if exposed to rain or moisture.

Is IP67 enough for outdoor signs?

For most outdoor signage applications, IP67 provides more than enough protection against rain, snow, and humidity.

Is IP68 always better than IP67?

Not necessarily. IP68 offers greater water resistance but may be unnecessary for standard outdoor installations and typically costs more.

Can waterproof LED neon signs be left on overnight?

Yes. High-quality waterproof LED neon signs are designed for continuous operation and can safely remain illuminated overnight when installed correctly.

Final Thoughts

So, can LED neon signs get wet? Absolutely—but only when they are designed with the appropriate waterproof protection.

For most outdoor signs, IP67 waterproof LED neon signs provide excellent protection against rain, dust, and harsh weather. If your installation is near pools, fountains, or areas with frequent water exposure, IP68 waterproof LED neon signs offer the highest level of water resistance available.

Before purchasing, always verify not only the sign's waterproof rating but also the protection level of the power supply, connectors, and wiring. Choosing the right waterproof specification ensures your LED neon sign remains bright, safe, and reliable for years to come.
