color strongly, unfortunately aging too fast

I have the film for a shelf with free-hanging glass shelves in the bathroom in operation. The floors are backlit with cold-white LED's. This is so at the factory. With the film, the floors now radiate golden yellow. Unfortunately, the LEDs have such high power densities that the film, as in front of it sits faded quickly. Every four weeks I have to continue to push the 2 mm sheet, then it is again really orange. Because of the short shelf 2 star deduction. Not because of the price-performance ratio, but the resulting maintenance.
