Chinese Professional Illuminated Sign Letters - Day/Night Channel Letters Front Lit Channel Letters Signage With Perforated Films – River Stone

Day/Night Channel Letters

The way this works is through perforated black vinyl (perforated films) laid over white faces. There a tiny holes in the black vinyl that will allow light to pass through and at night these channel letters will illuminate as if they were white. Below is a more detailed close up of what this vinyl looks like. This technique is great to use when may have two different colors you want for your sign during the day versus the evening, even for the few municipalities that are restrictive on color of illumination.

This way to be used for medium-term, large-scale backlit external signage where close viewing is not required.
