Another issue that needs to be noted is the IP protection level of lamps and lanterns, which is an indicator of the classification of electrical equipment according to its dust and humidity characteristics. IP protection level is composed of two numbers. The first number indicates the level of dust-proof and invasion-proof of electrical appliances (the external objects include tools, people's fingers, etc. can not touch the charged part of the electrical appliances, so as to avoid electric shock). The second number indicates the degree of sealing of electrical appliances against moisture and water-proof invasion. The larger the number is, the larger the meter is. The higher the protection level is.
And the outdoor wall lamp IP protection level is best to achieve IP53 or above, that is, to prevent dust into the interior of the lamps and lanterns to cause damage to the equipment, while preventing the water is not easy to cause internal damage to the equipment. Of course, the higher the IP protection level, the more durable it is.
