Not darkening!
To be clear, this window film does not darken. It will not block light versus not block light depending on whether it is on or not. It only frosts to provide privacy.It frosts very well, so if that's what you're looking for this will do it. But I was looking for something to block street lights from coming into my bedroom windows at night, and this does not do that.
