A storefront sign is a critical business asset. Every day, countless potential customers walk or drive past your storefront. But does it effectively draw people inside your business?
Channel letter signs are a standard industry solution for this purpose. They are custom-built, three-dimensional signs known for their durability and high visibility.
This guide will help you understand the benefits of channel letter signs. Let's cover their construction, types, lighting options, and the process of acquiring one.
What Are Channel Letters?
These storefront signs are individual, three-dimensional letters constructed from metal and acrylic. Each letter is fabricated separately and then assembled on-site. The name "channel letter" refers to the hollow channel created by the returns, which houses the lighting system.
The anatomy of 3D channel letters is simple:
- Face: The front surface, typically made of colored acrylic, is a lightweight plastic known for its clarity and color options.
- Return: The metal sides (usually aluminum) that create the depth of the letter. These sides are known as 'returns' because they return the face of the letter back toward the wall, forming a hollow space inside.
- Back: A metal plate that encloses the letter.
- Lighting: LEDs or neon tubes placed inside the letter cavity.
Types of Channel Letter Signs You Can Explore
There are three primary types of channel letters. The choice depends on desired aesthetics and building surface.
This is the most common type of illuminated channel letters. The acrylic face allows internal light to shine through, illuminating the entire letter. This style ensures maximum readability day and night, making it a functional choice for most retail and service businesses.
- Reverse (Back-Lit) Channel Letters
These custom channel letter signs have a metal face. Light is directed backward onto the building wall, creating an illuminated outline or "halo" around each letter. This style provides a modern, high-end appearance and is effective on textured surfaces such as brick or stone.
- Open-Face Channel Letters
These LED channel letters omit the acrylic face, exposing the light source (typically LED modules). This results in a very bright, raw light output. The style is often used for retro or industrial branding concepts. They require more maintenance due to exposed components.
Lighting Options: Channel Letters vs. Lightbox Signs
The choice of lighting impacts both performance and presentation.
- Channel Letters: Typically illuminated internally with LEDs, each letter stands out individually, creating a crisp, professional look that enhances brand visibility day or night.
- Lightbox Signs: Use a single illuminated cabinet behind a flat face. While cost-effective and easy to update, they provide a softer, less dimensional effect than channel letters.
Why LEDs Dominate
LED lighting has become the industry standard thanks to its:
- High energy efficiency and lower operating cost of channel letter signs
- Long lifespan (50,000+ hours)
- Durability and reduced maintenance needs
The Process: From Concept to Installation
Acquiring channel letter signs for retail involves a structured process. Working with Baltimore Signsmiths ensures correct execution.
- Consultation: The process begins with discussing your requirements, including brand goals, signage purpose, and budget. We will assess your location's visibility and mounting surface.
- Design and Quotation: Our company's designers create a digital mockup based on your logo and specifications. This proof includes details on dimensions, colors, and type. A formal quote is provided for approval.
- Permitting: Channel letter sign installation requires approval from local municipal authorities. We manage the permit application process. We ensure the design complies with all local zoning and building codes.
- Fabrication: After permit approval and your final sign-off, fabrication begins. This involves metal bending, welding, painting, acrylic face fabrication, and precise LED installation.
- Installation: Our certified technicians install the final product on your building. This involves safely securing the letters, connecting electrical wiring, and ensuring proper weather sealing. Professional installation is necessary for safety, functionality, and longevity.
Maintenance and Care of Your Signs
Maintenance of channel letter signs is minimal. Basic care extends their operational life.
- Periodically clean the acrylic faces with a soft cloth and a mild detergent solution. This removes dirt and grime that can reduce brightness.
- Visually inspect your building sign for damage. Contact us promptly to address issues such as water ingress or flickering LEDs.
- Schedule a professional inspection every few years to check electrical connections and mounting hardware.
