What type of cable assembly is most appropriate for outdoor lighting applications?

Weather-resistant cable is the most appropriate choice for outdoor lighting applications due to its ability to withstand various environmental conditions. Outdoor installations face exposure to moisture, temperature fluctuations, UV radiation, and other elements that can deteriorate standard indoor cables over time. Weather-resistant cables are specifically designed to resist these factors, often featuring additional insulation and protective coatings that help prevent water ingress and protect against UV damage, thus ensuring the longevity and safety of outdoor electrical systems.

Low-voltage wire is also used in outdoor settings but is generally suited for specific applications such as landscape lighting and irrigation systems. It may not provide the robust protection needed for standard lighting circuits that require higher voltage and protective features. Standard indoor cable lacks the necessary weatherproofing, making it unsuitable for outdoor use. Non-insulated wire does not provide adequate protection against environmental hazards, making it unsafe and impractical for outdoor applications.

Therefore, for outdoor lighting installations, weather-resistant cable is essential to ensure safety and durability.
