Answer
If you are looking for a material to apply directly to your light box, or you would like window graphics that stand out at night, then Backlit Film may be a good material choice.
Backlit Film is a semi-translucent material that is designed to catch and distribute light when directly lit from behind. This adds more depth to the graphics and allows the design to be visible both night and day. The unique ability for Backlit Film to adhere to both acrylic and glass surfaces makes it great for backlit light boxes and window applications.
Choose the “Inside Glass” option for front adhesive decals that are applied inside the glass facing outside. This option is only recommended for clear acrylic panels and un-tinted windows.
If you would like an easily removable material that can be switched in and out of a lightbox, choose Backlit Poster instead.
