I bought this to cover up our BLUE alarm clock light. It did exactly as we wanted it to- toned down the blue light quite a bit- in fact, during the day you can't really read it unless you are close. However, at night, it is amazing how bright the blue light remains, although it is 100 per cent better than before. I will probably have to just replace the alarm clock at some point. The film itself clings and is easy to work with. I have a life time supply now.
