Outdoor lights refer to the lights that are used outdoors. Outdoor lights suffer more damage than indoor lights due to the harsh outdoor environment. To protect outdoor lights, appropriate protection measures should be taken when selecting outdoor lights. First, waterproof rating should be considered when selecting outdoor lights. Lights that are used outdoors need to be able to withstand all kinds of weather conditions. Therefore, when choosing the lights for outdoor use, you should make sure that the lamps have a high waterproof rating, otherwise it will easily stop working in rainy or humid days when it is raining. Second, choose an appropriate size. Outdoor lights need to be able to deal with all kinds of wind and rain, so the size should be larger than that of indoor lights. It is recommended that the width should be at least double that of the indoor lights, so as to prevent the lights from being blown away in strong wind or storms. Finally, pay attention to the material of the lights. Generally speaking, outdoor lights are made of stainless steel, aluminum alloy or plastic. Stainless steel will be relatively heavy, but better waterproof and corrosion resistance. Aluminum alloy is lightweight and has good performance in various weather conditions. Plastic is easy to be damaged by sunlight, so it is not recommended. In short, when selecting outdoor lights, waterproof rating, appropriate size, and durable material should be taken into consideration. Only in this way can outdoor lights have a good performance and long lasting time span.
