Not all LED light strips are waterproof. LED light strips on the market are divided into two categories: waterproof and non-waterproof, depending on their application scenarios. Waterproof light strips are mainly used in environments that need to resist moisture and water, such as outdoors, bathrooms, swimming pools, etc. In contrast, non-waterproof light strips are more commonly used in indoor scenarios, such as home decoration, store displays, and office spaces. These light strips are not specially waterproofed during the production process, so they are easily damaged when used in humid environments. When purchasing LED light strips, it is important to know whether they are waterproof, especially if you plan to install them in areas where they may be exposed to moisture.
“How to Identify Waterproof vs Non-Waterproof Strips”
It is not difficult to distinguish waterproof from non-waterproof LED light strips. There are usually several simple ways to identify them:
Material appearance: Waterproof LED light strips are usually wrapped in a layer of transparent or translucent silicone, PVC or epoxy resin to form a protective layer. This material not only effectively blocks moisture from entering, but also protects the light strip from physical damage to a certain extent. In contrast, non-waterproof light strips are exposed to the outside, and the lamp beads and circuit boards are directly exposed to the air without an additional protective layer.
IP rating: The IP rating of the light bar is usually indicated on the light bar packaging or product specifications. The IP rating is an important mark to distinguish the protection ability of the light bar. Specifically, ratings such as IP65 and IP66 indicate that the light bar is waterproof, while lower ratings such as IP20 indicate that the light bar is not waterproof.
Usage scenario: The applicable scenario of the light bar is usually mentioned in the product introduction. For example, light bars that are clearly marked as suitable for outdoor, bathroom or other humid environments are usually waterproof.
“IP Rating and Water Resistance of Light Bars”
The protection level of waterproof light bars is usually indicated by the IP (Ingress Protection) code, and the second digit of the IP code indicates the waterproof ability. Common IP ratings for waterproof LED light bars include:
IP65: This rating indicates that the light bar can prevent the intrusion of jets of water, but cannot be completely immersed in water. IP65 light bars are suitable for outdoor rain environments, but it is not recommended to soak in water for a long time.
IP66: Similar to IP65, but with stronger waterproof performance and can prevent stronger water spray or wave impact.
IP67: This rating means that the light bar can be immersed in water for a short period of time, generally 30 minutes, and the depth does not exceed 1 meter. This type of light bar is suitable for temporary submersion environments, such as the edge of a garden pool.
IP68: This rating means that the light bar can be immersed in water for a long time, and the specific depth and time need to be based on the manufacturer’s specifications. This type of light bar is often used in swimming pools or other places where it is immersed in water for a long time.
In general, if the application needs to be immersed in water for a long time, it is recommended to choose IP68-rated light bars. IP65 and IP66 light bars are more suitable for outdoor rainproof or temporary water contact environments.
Installing IP67 light bars in swimming pools
Special attention should be paid to installing waterproof light bars in swimming pools to ensure that the light bars are not only waterproof, but also can withstand long-term immersion in water. Here are the installation steps:
Choose the right light bar: As mentioned earlier, IP68-rated waterproof light bars should be selected in swimming pools. These light bars are specially designed to be used underwater for a long time.
Prepare installation tools: Tools such as waterproof glue, sealing tape, and mounting clamps are required for installation. These tools can help ensure that the light bar is firmly fixed and the joints are sealed to prevent moisture from seeping in.
Determine the installation location: Choose the installation location of the light strip, which should usually be placed at the edge or bottom of the swimming pool wall. This not only creates a beautiful light effect, but also prevents the light strip from being damaged by external forces.
Laying the cable: Since the light strip needs to be connected to the power supply, the laying of the cable is particularly important. Make sure the cable is also waterproof and use a sealed connector to connect to prevent the wires from being exposed to water.
Test operation: After installation, test the operation of the light strip without filling it with water to ensure that all connections are good and the light strip brightness is normal before filling it with water for use.
How to cut waterproof light strips?
Cutting waterproof light strips requires extra care to avoid damaging the waterproof layer. Here are the cutting steps:
Find the cutting mark: Most LED light strips have pre-marked cutting marks on them, which are usually located between two lamp beads. Be sure to cut at these marks to avoid damaging the circuit.
Use sharp scissors: Choose a sharp pair of scissors to ensure a smooth cut. If possible, it would be better to use professional cutting tools.
Reseal the cut: After cutting, the cut part of the light bar will be exposed and needs to be resealed to maintain waterproof performance. Silicone or other waterproof sealing materials can be used to cover the cut part to ensure that moisture cannot penetrate.
Connect a new power cord: If you need to continue to use the cut part after cutting, you may need to weld a new power cord and seal it again.
Connecting IP67 Light Bars to Outdoor AC Power
When installing waterproof light bars on outdoor trees and powering them with AC power, pay attention to the following steps:
Choose a waterproof power adapter: Since the outdoor environment will inevitably encounter moisture or rain, it is crucial to choose a waterproof AC power adapter. It is usually recommended to choose an IP65 or higher power adapter to ensure safety.
Install a waterproof connector: At the connection between the light bar and the power adapter, use a waterproof connector for sealing to prevent rain from entering the connector and causing short circuits or damage.
Cable routing: Make sure that the cable is laid reasonably, not only to ensure beauty, but also to avoid excessive pulling or winding to prevent cable wear or breakage. In addition, cable ties can be used to fix the cable to the tree trunk to avoid looseness.
Testing and safety check: After the connection is completed, first test to ensure that the light strip is working properly. Then, check the entire wiring system to ensure that there are no exposed wires or loose joints. If necessary, waterproof tape can be used to further protect the wires.
Set a timer or remote control: For ease of use, a timer or remote control system can be installed to facilitate remote control or timed switching of lights and save energy.
Conclusion
By understanding the above, you should now be able to better understand and distinguish between waterproof and non-waterproof LED light strips. Correctly selecting and installing waterproof light strips, especially in outdoor or underwater environments, can not only extend the life of the light strip, but also ensure its safety and functionality. Whether it is the underwater lighting design of the swimming pool or the holiday decoration of the outdoor trees, it is crucial to choose the right LED waterproof light strip and the correct installation method. For wholesalers like you, mastering this knowledge can not only help customers make wise choices, but also enhance your service quality and professional image.
