Side-Lit Channel Letters

Edge-Glow LED Letters for Contemporary Architectural Signage

Side-Lit Channel Letters, also known as Edge-Lit Channel Letters, create a modern architectural lighting effect by emitting illumination from the sides of the letter rather than the face or back. This distinctive edge-glow design delivers a sleek and contemporary aesthetic suited for high-end commercial environments.

Instead of a glowing face or halo effect, light radiates through translucent acrylic side panels, while the front face remains solid and non-illuminated—creating a bold contrast between illuminated edges and a clean metal or acrylic face.

What Are Side-Lit Channel Letters?

Side-lit channel letters are fabricated using:

• Stainless steel or aluminum returns (structure)

• Translucent acrylic side panels for illumination

• Solid non-illuminated front face

• Internal LED modules for edge lighting

The LEDs are installed internally to direct light outward through the acrylic sides, producing a continuous glow along the letter perimeter.

This construction creates:

• Strong edge definition

• Modern architectural lighting

• Clean solid face appearance

• Refined nighttime presence

Construction & Materials

Side-lit letters are engineered for structural durability and long-term performance.

• Returns (Structure): Stainless Steel or Aluminum

• Side Panels: Translucent Acrylic (Illuminated)

• Face: Acrylic, Aluminum, or Stainless Steel (Non-Light Passing)

• Illumination Type: Side Edge LED

• Electrical System: UL Certified LED modules with UL Certified driver

Corrosion-resistant materials ensure suitability for exterior building installations.

Mounting Options

Flush Mount

Letters mount directly against the wall surface with concealed wiring routed through rear wall access.

Stud Mount

Letters project slightly from the wall using threaded studs. This projection enhances edge glow visibility and increases dimensional shadow depth.

Rear wall access is required for routing electrical wiring and connecting to the power supply.

Common Applications

Side-lit channel letters are frequently selected for:

• Modern office buildings

• Technology company headquarters

• Creative studios

• Boutique retail storefronts
