channelletters

Channel letters are a type of three-dimensional sign used for business storefronts and building signage. They are typically mounted on exterior or interior walls and are designed to be visible both day and night. The letters are hollow and illuminated from within, creating a distinctive glow.

Construction and lighting are central to channel letters. Each letter usually includes a translucent face made of acrylic or polycarbonate, attached to a surrounding shell or return that forms the sides of the letter. The interior cavity houses a lighting element, most commonly LEDs in modern installations, though neon tubes were used in the past. Lighting can be front-lit, where light exits through the face, or halo-lit (reverse-lit), where light shines onto the wall behind the letter.

Materials and configurations vary. Returns are typically made from aluminum or other metals, chosen for weather resistance and structural strength. Faces come in colored translucent materials to achieve the desired appearance. Common configurations include standard channel letters, open-face channel letters (lacking a back wall), and reverse-lit or halo-lit designs. Channel letters are available in a wide range of sizes, fonts, and color options to match branding.

Installation and maintenance involve electrical and structural considerations. Letters are usually mounted with studs or brackets to the building surface, sometimes connected to a weatherproof raceway or power supply. Compliance with local sign codes, building codes, and electrical standards is often required, and permits may be necessary. Routine maintenance focuses on cleaning the faces and ensuring electrical components remain sealed and functional.

Channel letters are valued for brand visibility and night-time legibility, offering a durable, customizable signage solution for storefronts and corporate signage.
