Performance in terms of sealing: If the Solar Studs are not totally sealed, water will naturally leak in. This will result in a circuit short, with disastrous results. A qualified Solar Studs must therefore pass the seal. There are numerous ways to enhance Solar Studs‘ sealing abilities: (1) A distinct design. An isolation design is used for the internal circuit board and the LED lampshade. (2) Strong neutral bonding materials are used to ensure that the solar panel, the LED lampshade, and the road stud housing are tightly attached, with no gap in the middle, so that even if the LED lampshade is broken, the interior of the Solar Studs is still assured not to seep.
