In this guide, we’ll walk you through the benefits, applications, and installation tips to help you make the most of waterproof LED strip lights for your next project.

What’s Waterproof LED Strip Light?

Waterproof LED strip lights are flexible lighting solutions encased in protective materials, such as silicone or polyurethane, to prevent moisture and water from damaging the internal components. These lights are ideal for environments where they may come in contact with water, such as bathrooms, kitchens, outdoor spaces, pools, and fountains. By utilizing waterproof materials, these LED strips ensure longevity and safety in wet conditions.

What’s an IP Rating?

The IP (Ingress Protection) rating is an international standard used to define the level of protection an electrical device offers against solid particles like dust and liquids like water. IP ratings consist of two numbers: the first digit represents protection against solid objects, while the second indicates protection from liquids.

First Digit (Solids): Ranges from 0 (no protection) to 6 (dust-tight).

Second Digit (Liquids): Ranges from 0 (no protection) to 8 (protected against immersion in water).

For example, an IP65 rating means the device is dust-tight and protected from low-pressure water jets from any direction, making it ideal for outdoor use.

Types of Waterproof LED Strip Lights

Different waterproof levels are available based on the IP rating. Here's a breakdown of the types:

The common material to make waterproof LED strips

The most common materials used for waterproof LED strips are Epoxy resin, PU glue, and Silicone, each with distinct properties. Let’s compare them:

Epoxy Resin
Epoxy resin is a low-cost, easy-to-use material commonly found in budget LED strips. It has minimal toxicity, making it popular in cheaper products.

However, it has significant drawbacks:

Thermal conductivity is poor, which shortens the lifespan of the LED strips.

It tends to yellow within six months, impacting the light's color temperature.

Its temperature resistance is weak, causing it to harden and crack in cold conditions, especially below 0°C.

PU Glue (Polyurethane)
PU glue offers better performance than epoxy resin but at a higher cost. It resists yellowing, performs better in low temperatures, and has improved heat conductivity.

However, it also comes with downsides:

Toxicity is a concern, as PU glue releases unpleasant, harmful compounds after curing.

It is not suitable for high-temperature environments, as it cannot withstand temperatures above 80°C.

Silicone Glue
Silicone is the most expensive option but provides the best overall performance.

It combines the advantages of both epoxy resin and PU glue:

It has excellent heat and cold resistance, remaining stable in temperatures ranging from -50°C to 300°C, making it ideal for extreme environments such as saunas or refrigerators.

No yellowing occurs over time, maintaining color temperature stability, which is critical for high-end projects like hotels and yachts.

Silicone also has good thermal conductivity, which aids in heat dissipation. However, for high-power LED strips (over 20W/m), aluminum channels are recommended to further manage heat.

What’s the Wire Length Suggestion for Waterproof LED Strip Light?

24V Voltage Drop & Wire Length Distance (3% Drop or 23.28V)

12V Voltage Drop & Wire Length Distance (3% Drop or 11.64V)

How to Choose a Power Supply for Waterproof LED Strip Lights?

Selecting the right power supply is critical for optimal performance and safety. Here’s how to choose one for waterproof LED strip lights:

Determine Voltage Requirements: Most LED strips operate on 12V or 24V. Check your strip’s specifications to ensure you select the right voltage power supply.

Calculate Wattage:

Multiply the wattage per meter of the strip by the total length of the strip to get the total wattage required. Add a 20-30% safety margin to ensure the power supply is not overloaded.

For example, if your LED strip consumes 5W per meter and you have a 10-meter strip:

5W/m × 10m = 50W.

Add a safety margin:

50W × 1.3 = 65W. You’ll need a power supply that can deliver at least 65W.

Here is a table for your reference:

Waterproof Power Supply:

If your installation is outdoors or in a wet environment, opt for a waterproof power supply (IP67 or higher).

Constant Voltage:

Ensure that the power supply is a constant voltage power supply, as LED strips are designed to operate under constant voltage conditions.

What Brightness Do You Want for Waterproof LED Strip Lights?

The brightness of LED strip lights is measured in lumens per meter (lm/m). The required brightness depends on the application:

Accent Lighting: 150-300 lm/m is ideal for subtle ambiance lighting in bedrooms, under cabinets, or along staircases.

Task Lighting: 500-700 lm/m is suitable for workspaces like kitchens, desks, and garages.

Outdoor and Pathway Lighting: 300-500 lm/m provides adequate brightness for outdoor paths, gardens, and decks.

High-Brightness Applications: 1000+ lm/m is recommended for larger areas or places where bright lighting is essential, such as outdoor patios or pool areas.

Consider choosing dimmable LED strips if you want flexibility in adjusting the brightness for different scenarios.
