Waterproof LED Strip Light ( IP55, IP65, IP67) Buying Guide

LED strip lights are widely used, in households and offices. But on many occasions, we need to use waterproof strips. Such as in the bathroom, kitchen, outdoor, swimming pool, sauna, and so on.

Waterproof LED Strip Lights

Waterproof LED strip lights are designed with IP65, IP67, or IP68 grade waterproof rating. Therefore they can be used in wet locations. The IP code is an international standard for rating the water resistance of electrical equipment. In this article, we will discuss the different levels of waterproof ratings for LED strip lights and the advantages and disadvantages of each one.

    1, What is IP Rating?

    LED strip lights can be used in the bathroom for decoration or to provide light for makeup.

    The kitchen is also a place that needs waterproof strips. You can put it on the ceiling and use it as a lamp or even as a decoration for your kitchen.

    If you want to install LED strip lights outside your home or office, then this is one of the best choices that you can make because it has high resistance to water or moisture. It will not be damaged due to rain or humidity if you want them installed outdoors.

    3, How Many Different Ways to Waterproof LED Strip Lights?

    KayTai is a professional led lighting manufacturer. There are different ways to waterproof led strip lights. If you want to waterproof the led strip lights, here we will introduce the silicone gel and silicone sleeve for waterproof of LED strip lights.

    IP55 Waterproof - Silicone Coating

    Waterproofing: Adding a layer of silicone coating on top of the strip. It prevents dust and moisture.

    IP55: 5 represents good dust-proof and touch protection, and 5 represents good moisture proofing.

    Application: Suitable for dry or wet areas, such as the living room, kitchen, and bathroom. It’s not recommended to use it where water can be splashed.

    IP65 Waterproof - Silicone Tube

    Waterproofing: Wrap the strip with a hollow silicone casing. Seal both ends with silicone end caps.

    IP65: 6 represents good dust-proof and touch protection. 5 stands for preventing spraying water from all directions.

    Application: Suitable for wet or water splashed areas for e.g. the kitchen, bathroom, eaves. As the casing is hollow, it’s not recommended for outdoor use.

    IP65 Waterproof - Silicone Tube+Silicon Injection

    Waterproofing: Wrap the strip with a hollow silicone casing. Then, fill the hollow casing with silicone to form a sealing effect.

    IP67: 6 represents good dust-proof and touch protection. 7 stands for underwater protection against water intrusion.

    Application: can be immersed in water, such as a swimming pool, or fish tank.

    4, What Material Can Make Waterproof LED Strips?

    This article will cover three types of waterproof materials, but before we start talking about them let’s understand why we need them and what are their pros and cons.

    When it comes to waterproofing, there are three most popular types of materials:

    • Epoxy resin
    • PU glue
    • Silicone glue

    4.1 Epoxy Resin

    KayTai Epoxy resin has the advantages of low cost, good maneuverability, and low toxicity. So, it’s a popular waterproof material for most cheap LED strips on the market. But there’s a fatal flaw in its molecular structure.

    First of all, its heat conductivity is poor, this will reduce the lifespan of the strip lights. Secondly, epoxy resin is easy to yellowing after half a year, this yellowing will affect the color temperature of the strip lights. Besides, the epoxy resin cannot resist high and low temperatures. It will harden and crack very easily under an ambient temperature below 0°C.

    4.2 Polyurethane Glue

    The cost of KayTai PU glue is higher than epoxy resin. It has better yellowing resistance, low-temperature resistance, and better thermal conductivity. But it’s toxic. When polyurethane adhesive is cured, it will produce some small molecular compounds. These compounds have a very bad smell and are not conducive to health. Secondly, it is not resistant to high temperatures. Do not use the strip with PU glue in places where the ambient temperature is higher than 80 ℃.

    4.3 Silicone Glue

    The cost of KaiTai silicone glue is the highest. It is an environmentally friendly material and has the advantages of both PU glue and epoxy gel. First of all, the heat resistance and low-temperature resistance are very good. The ambient temperature of -50 °~ 300° won’t affect its structure and performance. We can rely on Silicon LED strips for saunas and refrigerators. Secondly, the silicone glue will not turn yellow for a long time. This also ensures the long-term stability of the color temperature of the LED strip. It is particularly important for high-end lighting projects such as hotels, yachts, etc. As silicone glue has good thermal conductivity, it promotes the heat dissipation of the LED strip. But, we need to add aluminum channels for high-power (over 20 W) strip lighting for heat control.

    Waterproof led strip lights are a very good lighting product. They have many waterproof rating, and we can choose different IP rating for our outdoor application.

    What IP rating should I use outside?

    The IP rating is a numeric code that indicates the degree of protection provided by the enclosure. The first digit indicates the protection against solid objects such as dust, while the second digit refers to liquid ingress protection. The third digit represents the degree of protection against mechanical stresses such as vibration and shock.

    IP Rating Chart:

    0 – No special protection (transparent)

    1 – Protected against solid bodies larger than 50mm (e.g., finger)

    2 – Protected against solid bodies larger than 12mm (e.g., tools and wires)

    3 – Protected against solid bodies larger than 2.5mm (e.g., tools, wires and small wires)

    4 – Protected against solid bodies larger than 1mm (e.g., large wires)

    5 – Protected against immersion between 15cm and 100cm (e.g., washing machine)
