How are waterproof lights waterproof? How long is the normal lifespan?

There is a type of lamp specifically designed for lighting equipment in outdoor or humid environments, which has the characteristics of being waterproof and dustproof. This is called a waterproof lamp. How are waterproof lights waterproof?

Two Principles of Waterproof Lamps

There are two principles for waterproof lamps. One method is to use a sealed structure to isolate the light source and power supply, preventing moisture from entering the interior. This structure usually includes parts such as lamp shells, sealing rings, glass, etc., which can effectively prevent water infiltration. Another method is to use an airtight structure to seal the entire lamp body, forming an airtight space. This structure is more reliable in terms of waterproof effect, but has a higher manufacturing cost.

Lifetime of waterproof lamps

The lifespan of ordinary waterproof lamps is generally around 2-5 years, which depends on factors such as the quality of the lamp, usage environment, and usage method. Generally speaking, the lifespan of waterproof lamps is related to their sealing performance, material quality, etc. High quality waterproof lamps can have a lifespan of over 5 years. In actual use, if the lamp is frequently corroded by rainwater or moisture, its lifespan will be correspondingly shortened.

The waterproof performance of waterproof lamps is very important for lighting equipment in outdoor or humid environments. In addition to sealing and airtight structures, there are also other waterproof measures that can be taken, such as using special materials, coating treatment, etc. When purchasing waterproof lamps, attention should be paid to selecting products with reliable quality and stable performance to ensure their long-term stable operation.

So, waterproof lamps are a very practical lighting device with waterproof, dustproof and other characteristics, which can be used safely and reliably outdoors or in humid environments. Considering the service life of waterproof lamps, it is recommended to purchase high-quality ones and cherish them during use, which will last longer.
