2. What is an IP Rating?


The Ingress Protection (IP) rating is an international standard (IEC 60529) that classifies the degree of protection provided by electrical enclosures against the intrusion of solid objects (including dust) and liquids (especially water). It consists of two digits:  
The first digit (0-6 or X): Indicates the level of protection against solid objects.   
The second digit (0-9 or X): Indicates the level of protection against liquids.  
For waterproof LED strip lights, we are primarily concerned with the second digit. Here's a breakdown of what the common second digits mean:
0: No protection against liquids.  
1: Protection against vertically falling water drops.
2: Protection against vertically falling water drops when the enclosure is tilted at an angle of 15 degrees.  
3: Protection against spraying water at an angle of up to 60 degrees from the vertical.  
4: Protection against splashing water from any direction.
5: Protection against water jets from any direction.
6: Protection against powerful water jets.  
7: Protection against the effects of temporary immersion in water (up to 1 meter depth).  
8: Protection against the effects of continuous immersion in water (beyond 1 meter depth, specified by the manufacturer).
9: Protection against powerful high-temperature water jets.

This is ideal for pool lighting, underwater features, and marine applications.

5. Confusion Between IP54 and IP65 LED Strips


It's easy to get IP54 and IP65 confused, as both offer some level of water protection. The key difference lies in the type of water exposure they can withstand:
  • IP54: Protected against splashing water from any direction. Think of accidental splashes from a sink or light rain.  
  • IP65: Protected against water jets from any direction. This means it can handle more forceful water exposure, like being sprayed with a hose.  
For outdoor applications where direct rain or washing is expected, IP65 is generally the minimum recommended rating.

6. Common Materials Used to Make Waterproof LED Strip Lights


The waterproof protection of LED strips is typically achieved using these materials:
  • Epoxy Resin: A hard, rigid resin that can be applied as a coating. While offering good protection, it can sometimes yellow or crack over time with UV exposure or flexing.  
  • PU Glue (Polyurethane Glue): A flexible adhesive that can provide a degree of water resistance (typically IP54). It's generally less robust against prolonged water exposure compared to silicone.
  • Silicone: A highly flexible, durable, and UV-resistant material that offers excellent waterproofing capabilities (IP65 and higher). It remains flexible over a wide temperature range and is a popular choice for higher IP ratings. ADLED is a high-quality LED strip light manufacturer. All of our waterproof LED strip lights use premium silicone waterproofing to ensure excellent durability and long-term performance.
