The reason why the lamp strip is added to the silica gel itself is that the transparency of the silica gel is not bad, and the silica gel material is soft and will not damage the lamp strip.

Moreover, silica gel itself has good insulation and sealing functions, which can prevent electric shock and water leakage and further protect the lamp belt. Silica gel itself can also be made into various colors, which can make the lamp strip more colorful under the irradiation of light. I hope it helps you!
