[DelLillian]

LLumar's exclusive supply for 4S stores includes three main series: Zunyi, Changyi, and Siyi. Here is more information about LLumar: 1. Automotive window films: Thermal insulation performance is the most important. 2. Thermal insulation performance: Among the products exclusively supplied to 4S stores, the Zunyi series outperforms the Changyi series, which in turn outperforms the Siyi series in terms of thermal insulation. 3. Functions: LLumar products are installed on the inner side of the glass and primarily serve to block solar heat, thereby reducing heat damage to in-car instruments, lessening the burden on the engine, and creating a comfortable driving space. LLumar films also reduce glare, prevent blurred vision and visual fatigue, block UV rays that harm the skin, and provide a certain level of tint for privacy protection.
