Description
Lighting Style

Face of each letter is illuminated; the most common style.
LED or neon lights behind translucent acrylic faces
Back-lit (Reverse or Halo-lit)
Light shines from behind the letter, creating a halo effect on the wall.
Opaque faces, clear backs; soft glow around each letter
Front & Back-lit (Combination)
Both the face and the back are illuminated for a dramatic effect.

Open Face
Typically uses neon tubing visible through a clear face or open front.

How Are Channel Letter Signs Made?
Channel letters are custom fabricated, usually from sheet metal like aluminum for durability and corrosion resistance. The faces are generally made from acrylic or polycarbonate for light transmission. Letters are painted or finished to match a business’s branding.
Typical Materials Used
Aluminum: For structural sides and backs (called “returns” and “backs”)
Acrylic or polycarbonate: For the translucent face of each letter
LED modules or neon tubing: For illumination inside the letter
Steps in Manufacturing Channel Letters
Design and layout customized for business branding
Cutting metal and face materials to shape
Forming the letter returns (sides) and backs
Painting and finishing components
Inserting lighting elements (LEDs or neon)
Final assembly and wiring for power
How Are Channel Letter Signs Installed?
Installation is another key part of channel letter sign usage. Signs may be:
Mounted directly to the building wall (flush mount)
Mounted to a “raceway” (an electrical mounting box that attaches to the wall)
Attached to a backer panel if the wall surface is unsuitable for direct mounting
Electrical connections are made to power the lighting, and installation must follow local building codes and safety standards.
Why Are Channel Letter Signs Popular for Storefronts?
Businesses choose channel letter signs for several important reasons:
Visibility: 3D illuminated letters stand out both day and night
Professional appearance: Individual letters look modern and high-end
Brand customization: Colors, fonts, sizes, and lighting match brand identity
Energy efficiency: Use of LEDs reduces power consumption and maintenance costs
Durability: Aluminum and acrylic construction resists weather and corrosion
Compliance with sign codes: Many cities require individual letters rather than large sign boxes for aesthetics
