Outdoor wall lights not only have lighting functions, but also need to deal with a variety of external environmental factors, especially the invasion of water. The quality of waterproof performance is directly related to the service life and safety of the lamp. Therefore, it is particularly important to regularly evaluate the waterproof performance of outdoor wall lights.

Understand the waterproof rating
Before evaluating the waterproof performance, it is crucial to understand the waterproof rating of the lamp. The International Protection Rating (IP rating) established by the International Organization for Standardization (ISO) is an important standard for evaluating the waterproof performance of lamps. The IP rating consists of two numbers:
The first number indicates the protection against solid objects, ranging from 0 (no protection) to 6 (completely dustproof).
The second number indicates the protection against liquids, ranging from 0 (no protection) to 9 (can withstand high-pressure water jets).
For wall lights used outdoors, it is recommended to choose products with IP65 and above to ensure that they have good waterproof performance and can effectively resist the intrusion of rain and other liquids.

Check the sealing
The sealing of the lamp is a key factor in ensuring waterproof performance. It is important to check the following aspects regularly:
Sealing strips: The sealing strips of lamps are usually made of rubber or silicone materials, and they must be intact. Check whether the sealing strips are aging, cracking or deforming, which will directly affect the waterproof ability of the lamp. If any problems are found, they should be replaced in time.
Joints: The joints of lamps are the areas where moisture is most likely to penetrate. Check these places regularly for obvious gaps. If gaps are found, it is recommended to use waterproof glue for sealing to prevent moisture intrusion.
Connection between lampshade and lamp body: Make sure that the connection between the lampshade and the lamp body is not loose or falling off, which is also an important part of ensuring waterproof performance.

Check drainage design
Some outdoor wall lamps are designed with drainage holes to prevent moisture accumulation. When checking the drainage design, pay attention to the following points:
Unblocked drainage holes: Regularly check whether the drainage holes are blocked by debris and keep them unblocked to ensure that moisture can be discharged smoothly.
Rationality of drainage design: Ensure that the drainage design of the lamp is reasonable and can effectively guide the water flow to prevent moisture from accumulating inside the lamp and affecting its normal use.

Observe the use environment of the lamp
The use environment of the outdoor wall lamp cannot be ignored in its waterproof performance. The following factors need to be considered:
Installation location: Choosing a suitable installation location can significantly reduce the intrusion of moisture. Avoid installing the lamp in an area prone to water accumulation, or choose a sheltered place to reduce the impact of moisture on the lamp.
Surrounding plants: Regularly observe the growth of plants around the lamp to avoid excessive growth of trees or shrubs that block the lamp and cause moisture to accumulate around the lamp.
Climatic conditions: After heavy rain, snow or other extreme weather, it is especially necessary to check the waterproof performance of the lamp to ensure that the lamp can still work normally under these conditions and avoid failures caused by weather changes.
