What happens if my LED lights get wet?
LED lights have become a popular and energy-efficient choice for outdoor lighting. However, exposure to natural elements can sometimes pose unforeseen challenges. One common concern for homeowners is the potential consequences when outdoor LED lights encounter moisture. In this blog post, we will delve into what happens when water enters external LED lights and explore features that help prevent water ingress.
Waterproof Ratings for LED Light Strings:
- Dry-rated LED lights are suitable for indoor use, away from water sources.
- Moisture-resistant LED lights can withstand direct contact with water and are suitable for places with minimal moisture accumulation, such as laundry rooms, bathrooms, or covered patios.
- Wet-rated LED lights can be exposed to dripping or flowing water. They are tightly sealed to prevent any moisture from entering the bulb. These lights are ideal for areas near swimming pools or regions expecting rain or snow.
Risks of LED Lights Immersed in Water: The primary risk when LED lights are exposed to water is the potential for electrical accidents when fully submerged. Since water is a conductor, there is a risk of a deviation in the flow of current, leading to potential hazards.
Dealing with Moist LED Light Strings: Here is a quick and simplified guide on what to do when LED light strings get wet:
- Determine the humidity rating. If it is a moisture-resistant LED light string, it typically poses no significant issues. Ensure that you can safely access power in humid conditions without touching live wires. If the fixture should not or cannot be exposed to humid environments, disconnect it from the power source.
- Remove water from LED light bulbs if necessary. Wipe them clean and let the wires air-dry for a few days. Only reconnect them to the power source when you are sure they are completely dry. Clean the area before testing the LED, taking necessary safety precautions.
The tolerance of LED lights in water depends on their sealing method.
Waterproof Measurement for LED Lights: A common method for measuring this tolerance is to refer to the Ingress Protection (IP) rating table, also known as International Standard IEC 60529. The IP rating is a two-digit code, such as IP65.
- The first digit indicates the ability to resist various sizes of objects (such as hands or dust particles).
- The second digit indicates moisture resistance, including dripping, splashing, spraying, jetting, and complete immersion.
Conclusion: Choosing outdoor LED lights capable of withstanding humid conditions is the first line of defense against water damage. Selecting lights with an IP rating of 65 or higher indicates dust resistance and protection against water splashes from any direction. Additionally, consider applying waterproof silicone sealant around edges or openings where water may seep in. Installing protective covers or enclosures, such as glass or plastic lampshades, can further shield the lights from direct exposure to rain or snow.
It's important to note that while waterproofing helps protect outdoor LED lights, it is not a foolproof solution. Over time, even the best-protected fixtures may experience wear and tear, potentially leading to cracks, breakages, or other issues that allow water to enter. Regular maintenance and inspections of outdoor lights are crucial to ensuring they continue to function properly and remain resilient to adverse weather conditions.
