Modern swimming pool lighting often features ring lights along both the interior and exterior walls, many using RGB IP68 waterproof neon flex. So, when designing lighting effects for pools, aquariums, or outdoor fountains, have you ever hesitated: “Can these flexible LED neon lights really withstand prolonged submersion?” More, pls check A Guide to Underwater Pool LED Strip Lights 2024
Many products on the market claim to be “waterproof,” but not all are truly suitable for underwater environments. IP68 waterproof LED flexible neon lights, due to their “long-term immersion capability,” have become a popular choice for underwater lighting.
However, does the IP68 waterproof neon flex mean absolute safety? What are the key installation details? Are the differences between ordinary waterproof lights and IP68 LED strips?
What is an IP68 Waterproof Rating?
IP (Ingress Protection) is a protection rating standard established by the International Electrotechnical Commission (IEC) to measure the ability of electrical equipment to protect against external solids and liquids.
In IP68, the “6” represents the dustproof rating, indicating complete protection against dust ingress, achieving a “dusttight” level; the “8” represents the waterproof rating, indicating that the equipment can be continuously submerged in water for extended periods under conditions specified by the manufacturer without water ingress.
Once a manufacturer labels a product with an IP68 waterproof rating, it means it can be submerged in water and used in swimming pools. Although there is no uniform mandatory standard for IP68, a common definition is a depth of 3 meters underwater. True IP68 products must pass rigorous third-party immersion tests to ensure normal operation in long-term underwater environments.
Are IP68 Waterproof LED Neon Flex Truly Suitable for Underwater Use?
Yes, genuine IP68 waterproof LED neon flex lights can be safely used underwater. Therefore, if you are purchasing IP68 neon tubes, pay close attention to the product details. Ideally, they should meet three key conditions: Pls check Why Choose LED Neon Flex for Your Swimming Pool Lights?
- The LED strip itself meets IP68 standards: it uses a fully encapsulated liquid silicone sealant in a single, seamless design, capable of withstanding underwater water pressure.
- All connectors are completely sealed: IP68-specific waterproof connectors must be used at all connections, with double protection from heat-shrink tubing. Connectors are a high-risk area for underwater malfunctions.
- Waterproof power supply: The transformer (power adapter) must be installed in a dry location above the water surface; underwater power supply is strictly prohibited.
Additionally, it’s crucial to note that not all products labeled “IP68” are reliable. Inferior products may use ordinary potting processes, which can cause the silicone to crack or delaminate after prolonged immersion in water, leading to water ingress and short circuits. Therefore, it’s best to discuss warranty details with the supplier and request samples for testing.
Which IP68 Waterproof Neon Flex Are Suitable for Underwater Pool Lighting?
We recommend three IP68 neon tubes that have been tested and are suitable for pool and underwater lighting installations.
Top view IP68 Neon Flex: T1616
The T1616 model features a top-emitting structure, providing uniform illumination at the pool edge, steps, or bottom. It has a full silicone extrusion encapsulation, is resistant to yellowing, and is waterproof to a depth of 1.5 meters.
It also supports monochrome or RGB, RGBW control. In short, the T1616 is ideal for pool contour lighting or underwater architectural lighting projects.
Side View IP68 Neon Flex: S1225 & S1616
The S1225 and S1616 feature a side-emitting light design, making them particularly suitable for installation on curved walls, underwater cabling, or narrow edges.
They provide soft, glare-free side lighting and support the DMX512/RGB control system, enabling dynamic underwater color-changing effects.
How to Use IP68 Neon Lights Correctly and Safely Underwater?
To ensure the long-term stable operation of IP68 waterproof LED neon flex lights underwater, please refer to the following key details for installation and use:
- Check product IP68: Confirm that the LED strip, connectors, and power supply are clearly marked with IP68, and refer to the specifications.
- Seal all joints: Use dedicated IP68 waterproof connectors. After connection, use heat shrink tubing to shrink and ensure a seamless seal.
- Avoid mechanical damage: Do not bend excessively during installation (minimum bending radius ≥ 5cm). Use plastic clips for fixation and avoid sharp metal edges scratching the silicone layer.
- Power isolation: The power supply must be placed in a dry, ventilated onshore location, and a waterproof power cord must be used for connection.
- Test before filling with water: After installation, first power on and test the lighting effect to confirm there is no flickering or short circuit, then slowly fill the pool with water and observe.
IP68 Waterproof LED Neon Flex vs. Regular Neon Flex Comparison
IP68 waterproof LED neon flex lights are quite different from ordinary neon lights. Regular neon tubes have an IP67 waterproof rating and are only for outdoor use, not underwater. It’s important to note that only IP68 neon tubes can be used in swimming pools and underwater.
| Comparison | IP68 neon flex | Regular neon flex |
| Waterproof performance | IP68 neon tubes can be used for underwater and swimming pool lighting. | Standard neon tubes have an IP67 waterproof rating and are only suitable for outdoor lighting. They are only water-repellent or moisture-proof. |
| Outer material | All-silicone encapsulation | Partially filled with glue, the inside is hollow. |
| Service life | 3 years warranty | 3 years warranty |
| Application | Swimming pool, underwater, outdoor | Interior and outdoor decoration |
| Installation difficulty | Requires communication with an electrician. | It’s quite simple, you can do it yourself. |
In comparison, we can see that IP68 waterproof LED flexible neon lights not only have a high level of protection, but also better durability and luminous efficiency stability, making them the best choice for outdoor and underwater lighting projects.
How to Choose a High-Quality IP68 Waterproof LED Neon Flex?
When choosing an IP68 neon tube, you need to communicate with your supplier to confirm its IP68 rating and clarify the warranty period. The following details also require attention:
- Certifications and Testing Reports: Check if it has passed CE, RoHS, and IP68 certification tests;
- Colloidal Material: Utilizing premium all-silicone one-piece molded LED strips, resistant to yellowing and aging;
- Soldering Points and Waterproof Terminal Process: Employing professional potting technology and heat-shrink packaging for enhanced safety;
Conclusion
A high-quality IP68 waterproof LED neon flex, thanks to its professional encapsulation technology and top-notch protective design, is perfectly capable of handling underwater lighting tasks. Whether creating dreamy pool lighting or enhancing the quality of outdoor landscaping, our IP68 neon tube series delivers outstanding luminous efficacy and durability.

FAQs
Yes, they can be used underwater for extended periods. However, during installation, it is crucial to ensure that all accessories meet IP68 specifications.
We recommend the following three project-proven IP68 neon tubes: T1616: top view, suitable for pool edges or underwater lighting; S1225: side view, suitable for curved walls or recessed light troughs; S1616: Large-size side view type, higher brightness, suitable for large pools or landscape projects.
Yes, but you must choose LED strips made of corrosion-resistant silicone material and take additional protective measures. Salt water is highly corrosive and requires regular inspection and surface cleaning to prevent salt buildup.
The main thing is to confirm with the supplier whether it is IP68, and check if the product has an IP68 test report or third-party testing certifications (such as CE, RoHS). Furthermore, genuine IP68 light strips typically use a fully silicone one-piece molded encapsulation, rather than relying solely on an outer sleeve for waterproofing.
