Very well-designed and high-quality pole lamp! Aluminum is a great material for outdoor lighting because it is lightweight, strong, and resistant to the elements. Its waterproof and rust-resistant properties make it ideal for use in wet or humid environments, The transparent lampshade with high transmittance is also a great feature, as it allows for maximum light output while still providing a soft, diffused lighting effect. The lack of yellowing is also important, as it ensures that the lamp will maintain its clarity and brightness over time. The Spanish courtyard pole lamp is a great choice for anyone looking for a durable, high-quality outdoor lighting solution.
