Understanding the Impact of Environmental Factors on Garden LED Lighting: A Comprehensive Guide

Modified on Mon, 19 Feb 2024 at 05:52 PM


Investing in garden lighting can significantly enhance your outdoor spaces, transforming them into inviting and ambient areas for relaxation or entertainment. While IP65, IP67, and IP68-rated LED products, including LED strips and neon flex, are popular choices due to their water and dust resistance, it's important to understand that these products aren't invincible. They are designed to withstand certain environmental pressures, but extreme weather conditions, exposure to salty sea air, pool chemicals, or garden fertilisers can still significantly impact their performance and longevity.

Driver Installation Considerations

For an optimal garden lighting setup, we recommend installing LED drivers indoors to avoid direct exposure to outdoor conditions. This approach allows for the cabling alone to run through the garden. It's crucial to ensure correct cable sizing as long distances of 24V cabling can experience voltage drop, which impacts the lighting performance. In situations where it's necessary to install LED drivers outdoors, they must be housed in IP-rated protective boxes to safeguard against weather elements. Specifically, even though our drivers may have an IP67 rating, indicating a high level of protection against dust and water ingress, it's important to remember they are not IP68 rated and thus not designed for prolonged submersion or extreme weather conditions.

Warranty Information and Recommendations

Installing LED drivers in gardens without appropriate protective measures limits the warranty to 1 year due to the potential for weather-related deterioration. Conversely, installations utilising specialised waterproof boxes can extend the warranty to a maximum of 2 years. Proper installation by a skilled installer can significantly extend the operational life of the drivers, often beyond 5 years. However, as we cannot monitor installation quality, the warranty reflects this limitation.

The Impact of Extreme Weather and Flooding in the UK

UK weather, known for its frequent rain, occasional heavy downpours, and potential for flooding, poses significant challenges to the durability and performance of garden LED installations. Despite their resilience, these IP-rated products can be put to the test by persistent exposure to such harsh conditions. Over time, this can lead to degradation of the waterproof seals and an increased risk of water ingress, leading to potential product failure.

Heavy rainfall and flooding represent particular challenges. In the event of a flood, garden LED products can become submerged and exposed to debris and potentially corrosive substances. Even though these products are designed with water resistance in mind, long-term submersion and exposure to corrosive materials are beyond what they're designed to withstand.

Seaside Installations and Chemical Exposure

When installing garden LED lighting near the sea or a swimming pool, unique challenges can arise. The salty sea air and pool chemicals can cause corrosion over time, and the use of garden fertilisers can also contribute to material degradation. While the effects might not be immediate, continuous exposure to these substances can compromise the durability and functionality of your garden lighting system.

Prevention, Mitigation, and Maintenance

Recognising these challenges underlines the importance of proper installation and regular maintenance:

  • Installation: Carefully consider the location of your LED fixtures, especially in flood-prone or seaside areas. Employ protective measures or use housing solutions offering extra protection where necessary.
  • Maintenance: Regular maintenance is key to preserving the longevity of your garden lighting. Clean the LED products to remove any salt deposits or chemical residues. Regularly inspect them for signs of wear, damage, or corrosion, especially after extreme weather events or flooding. Promptly address any issues to prevent further deterioration.

Weighing the Commitment: Making the Right Decision

Before embarking on a garden lighting project, it's essential to consider your readiness to undertake the necessary maintenance. Garden lighting requires commitment. Regular inspections, cleaning, potential resealing, and prompt repairs are all integral to maintaining a garden lighting system.

If you're ready for these tasks, garden lighting can be a rewarding addition to your property. But if the prospect of this commitment is daunting, it may be worth reconsidering garden lighting or exploring less maintenance-intensive lighting options.

In conclusion, while IP65, IP67, and IP68-rated LED products are robust and resilient, they still require care and regular maintenance to ensure optimal performance and longevity. By understanding the environmental challenges and committing to routine maintenance, your garden lighting can continue to shine brightly, creating a captivating outdoor space, whatever the weather.
