led strip lights have transformed the way people illuminate their spaces — from cozy living rooms and outdoor gardens to modern kitchens and commercial displays. They are flexible, energy-efficient, and easy to install.
However, one question customers often ask is: “Are all LED strip lights waterproof?”
The simple answer is no. While some LED strips are designed to resist moisture and rain, not every model can handle wet or outdoor environments. Understanding the difference between waterproof and non-waterproof LED strips helps you choose the right product for your application and ensures long-lasting performance.
Waterproof LED strips are coated with a layer of silicone, epoxy, or polyurethane that shields the LED chips and circuits from moisture, dust, and oxidation. This coating forms a barrier against humidity, splashes, and even temporary submersion in some cases.
The level of water and dust protection is measured by the Ingress Protection (IP) rating. This system uses two digits:
The first digit indicates protection against solid particles like dust.
The second digit measures protection against liquids like water or steam.
| IP Rating | Description | Water Protection Level |
|---|---|---|
| IP20 | No special protection; for indoor dry areas only | None |
| IP44 | Protected from small splashes and condensation | Light moisture |
| IP65 | Resistant to low-pressure water jets and rain | Outdoor use |
| IP67 | Can withstand brief immersion in water | High protection |
| IP68 | Designed for continuous underwater operation | Maximum protection |
Not every LED strip carries a waterproof rating, and the absence of a coating means it should only be used indoors or in completely dry environments.
These are the most common type for indoor use. The LED chips and circuits are exposed, allowing maximum brightness and easier heat dissipation. They are ideal for living rooms, bedrooms, under-cabinet lighting, and display shelves but must be kept away from humidity or water exposure.
These strips are lightly protected and can handle minor moisture or occasional splashes. They are suitable for areas like bathrooms, laundry rooms, or semi-covered patios, but they cannot withstand heavy rain or direct water contact.
These models have a silicone or epoxy coating covering the LED surface, making them resistant to rain and wet outdoor conditions. They are perfect for gardens, balconies, signage, and outdoor pathways.
IP68 LED strips are completely sealed and can be submerged underwater for long periods. They are used in fountains, pools, aquariums, and marine environments, where durability against pressure and moisture is critical.
Manufacturers produce both waterproof and non-waterproof options because not all lighting needs involve water exposure. Waterproof coating increases cost and slightly reduces brightness due to the additional layer, so dry-use environments benefit from non-coated strips.
Waterproof coatings trap more heat around the LED chips. For installations that already have good ventilation or heat sinks, non-waterproof strips are preferred for better performance and lifespan.
Non-waterproof LED strips are easier to cut, solder, and bend around corners. Waterproof strips require cutting and resealing to maintain water resistance, which can be more complex during installation.
Waterproof LED strips cost more due to extra materials and manufacturing steps. For dry areas, using non-waterproof strips offers a more cost-effective and practical solution.
| Location | Recommended IP Rating | Notes |
|---|---|---|
| Living Room / Bedroom | IP20 | Dry, indoor use only |
| Bathroom Mirror or Sink Area | IP44 | Protects against splashes |
| Kitchen Under-Cabinet | IP54 | Withstands steam and occasional moisture |
| Outdoor Balcony / Patio | IP65 | Rain-resistant and durable |
| Garden Pathway / Signage | IP67 | Withstands weather exposure |
| Swimming Pool / Fountain | IP68 | Fully waterproof and submersible |
Choosing the correct waterproof level ensures optimal performance and safety for every setting.
Inspect Seals Regularly – Check for cracks or peeling on the silicone surface that could allow water in.
Use Waterproof Connectors – Ensure joints, power adapters, and connectors are sealed to prevent moisture leakage.
Avoid Sharp Bends – Excessive bending can break the waterproof coating and expose circuits.
Clean with a Damp Cloth Only – Never use chemical cleaners that may damage the silicone surface.
Proper Power Supply Placement – Keep power supplies and controllers in dry, protected areas even if the strip is waterproof.
Proper maintenance extends the lifespan of your LED lighting system, especially for outdoor applications.
At Keyfine LED, we manufacture both indoor and outdoor-rated LED strips that meet international protection standards. Our waterproof LED strip series feature:
High-grade silicone encapsulation for long-lasting protection
Stable voltage design to prevent flicker and brightness loss
UV and temperature resistance for outdoor performance
Strong adhesive backing for secure installation on multiple surfaces
Customizable IP ratings (IP20–IP68) to suit any environment
Each product undergoes strict waterproof testing to ensure consistent brightness and reliability under varying conditions.
So, are all LED strip lights waterproof?
No — only those with protective coatings and IP-rated sealing can resist water or moisture. Standard LED strips are for indoor use, while waterproof models are built for outdoor or wet environments.
Before purchasing, always consider where and how the lighting will be used. Matching the correct IP rating to your space not only protects your investment but also ensures safety and performance.
For both indoor elegance and outdoor durability, Keyfine LED provides a full range of LED strip solutions — delivering the perfect balance between brightness, protection, and design flexibility.
