Reverse channel letters are used by clients who want an impactful and classy look for their signage. Used indoor and outdoor, it also referred to as “halo” or “back-lit” letters. Reverse lit channel letter signs are mounted away from the wall, causing the light to form a halo effect behind the sign. The distance from the sign to the wall mount surface enables the halo of illumination around each individual character, helping the reverse lit channel letters to stand out.
