Focused on film quality
Kepler is a window film brand first. The ranges are developed for professional installation, with materials chosen for clarity, colour stability and consistent handling on the glass, and they are backed by product information that lets an installer explain what a film will and will not do. That matters, because the labels on window film can be confusing. Visible light transmission describes how much light passes through the film and glass; it says nothing on its own about how much solar heat is rejected. Two films at the same shade can perform very differently, so the comparison worth making is between named films at the same shade, not between dark and light.
