A fully customizable 3D acrylic letter sign built from solid light-diffusing acrylic, so the entire letter glows — face and sides together. Weatherproof and built for indoor or outdoor storefronts, lobbies, and displays.

Product Details

Make a lasting impression with fully illuminated 3D acrylic letters:

  • Edge-to-Edge Glow: Solid light-diffusing acrylic lights the entire letter — face and sides — for a soft, even block of light with no dark edges.
  • Fully Customizable: Choose your font, size, and color. Set face and side colors independently, or pick RGB for multi-color.
  • Versatile Use: A clean, modern look for storefronts, reception walls, restaurants, cafés, and interior displays.

Weatherproof
Built for both indoor and outdoor use in rain, snow, sun, and UV.

Dimensions:

  • Standard Heights: Available from 5” to 20”.
  • Custom Sizes: Larger sizes and custom logo shapes available upon request.

Materials & Construction:

  • Body: Solid light-diffusing acrylic — face and sides illuminate together (available in 13 colors plus RGB).
  • Side Color: Selectable independently from the face color.
  • Backing: Sturdy acrylic panel for structural integrity and secure mounting.
  • Lighting: High-brightness, energy-efficient LED modules (white or RGB).
  • Environment: Weatherproof and fade-resistant construction, designed for both indoor and outdoor installation.

How to Install Your Full Lit Acrylic Letters:

Step 1: Mount the Template
Tape the included paper installation template exactly where you want your sign to go. Use a level to make sure it’s perfectly straight before moving on.

Step 2: Drill & Feed Wires (For a Clean Look)
For a seamless look with no visible wires, use the guides on the template to drill small holes for each letter. Feed the attached wires through so the connections sit hidden behind the wall.

Step 3: Secure to the Wall
Attach each letter to your surface using the included screws — flush to the wall, or raised on studs/standoffs for added depth.

Step 4: Connect the Power
Once all letters are mounted and the wires are tucked behind the wall, connect to the 12V power supply via hardwire or the included plug-in adapter.

(Note: Because installation can involve feeding wires and making connections behind the wall, we recommend hiring a professional sign installer or electrician to ensure it’s done safely and correctly.)

Can these letters be used outdoors?

Yes. The solid acrylic construction is weatherproof and built for both indoor and outdoor installations.


How do the letters light up?

Each letter is made from light-diffusing acrylic with internal LED modules, so the entire letter glows — face and sides together — not just the front.


Can the face and sides be different colors?

Yes. Choose from 13 face colors and set the side color independently. Full RGB is also available for multi-color letters.


What size letters can I order?

Standard heights run from 5” to 20”. Larger custom sizes are available through our custom quote request.


Can I order a custom logo or shape instead of letters?

Yes. Upload your logo or design and we’ll build a custom illuminated sign to match your artwork.


What comes in the package?

Each order includes the LED-lit acrylic letters, the 12V power supply (hardwire or plug-in adapter), and the wall-mount hardware.


How do I install the letters?

Letters mount individually with the included screws — flush to the wall or raised on studs/standoffs. Most customers can install them, but professional installation is recommended for complex layouts or storefronts.


What is the production time?

Production takes about 8–12 business days, with shipping typically 6–8 business days after.


What other illuminated storefront sign styles do you offer?

Full lit acrylic letters are one of several illuminated sign styles we make. For a sharper, more traditional look with metal sides and a lit face, our Front-Lit Channel Letters light the face through a metal-sided body. For a softer glow that projects behind the letters onto the wall, our Backlit Channel Letters create an architectural halo effect. Or browse our complete custom business signs and storefront signage collection to compare all options.

Everything That Makes These Letters Shine

Edge-to-Edge Illumination

The entire letter is solid light-diffusing acrylic, so the face and sides glow together — a soft, even block of light with no dark edges, dim spots, or visible seams.

Two-Tone Color, Your Way

Choose from 13 face colors plus full RGB, and set the sides independently — a colored face with bright white returns, or any pairing you like, lit clean and saturated day or night.

Built to Fit Any Space

From storefront facades to reception walls and lobbies, the weatherproof acrylic build works indoors and out — mounted flush or raised on standoffs for added depth.
