LED Channel Letters

How Are LED Channel Letters Fabricated and Powered?

Custom channel letters are individually crafted three-dimensional characters spelling out your company name. Fabrication begins by feeding sheets of high-grade 0.040" structural aluminum into an automated CNC bending machine. The machine bends the aluminum strip coils to match the exact font geometry, creating the letter walls, which are called returns (usually 5 inches deep). A flat aluminum backing panel is then cut and welded to the returns using computer-guided stitch welders.

For face-lit configurations, the front of each letter is routed from 3/16" thick light-diffusing acrylic sheets. The acrylic face is permanently bonded to the aluminum returns using an extruded plastic trim cap. Inside the letter enclosure, we install parallel arrays of 12V Samsung LED modules with integrated optical lenses that project light at 160-degree angles. This ensures the sign face glows evenly without any dark spaces or bright spots. The individual letters are wired back through flexible conduit lines to a primary IP67-rated waterproof power supply, allowing the entire configuration to run safely on a low-draw 12V DC electrical current.

Why Face-Lit Channel Letters Make the Best Storefront Signs

When choosing signs for shopping plazas, office centers, and retail stores, business owners prefer channel letters because of their professional design and durability:

• 3D Visual Depth: The 5-inch return walls give the letters a strong physical depth, making your business name stand out visually from angle views, unlike flat signs.
• plaza-Compliant Standards: Most commercial property managers and municipal zoning boards in Florida strictly require individual channel letters on building facades, making this sign the perfect choice for regulatory compliance.
• Superior Contrast: Combining colored acrylic faces with dark return coatings ensures that your branding remains highly legible during high-glare daytime hours.
• Extreme Durability: Constructed with rustproof aluminum, UV-stabilized acrylic, and solid-state LED elements, our channel letters are built to withstand high winds, heavy rain, and intense solar exposure.

Raceway vs. Flush Wall Mounting Configurations

Depending on your building's facade and landlord guidelines, channel letters can be mounted in two ways:

Raceway Mounting: The letters are pre-installed on a long, rectangular metal mounting box (the raceway), which houses all the electrical wiring and power supplies. This approach is highly recommended because the raceway requires only a few mounting holes drilled into the building exterior, keeping building facade damage to a minimum.

Flush Mounting: Each letter is mounted directly to the wall surface using threaded metal pins, with the wiring fed individually through the wall to the power supplies stored inside the building ceiling. Flush mounting delivers a clean look, but requires more installation time and leaves a larger footprint of wire penetrations on the exterior surface.
