ABOUT BACKLIT CHANNEL LETTERS
Plan your project around backlit channel letters.
As a professional sign maker, we build high-quality backlit channel letters, custom-made to your needs and lit by LED: safe, reliable, excellent on display, UL Listed, and covered by a 3-year warranty.
Once you confirm the shop drawings, production typically takes about 15 business days, and DHL door-to-door delivery adds about a week, roughly 25 days from approval to your door.
What are backlit channel letters?
With backlit channel letters, each letter has its own light source and its own circuit: a hollow metal letter shell (called a channel in the U.S.) with LEDs inside. Light passes through the acrylic backing and forms a halo in the shape of each letter on the wall, so the sign highlights your brand while staying elegant, lit or unlit, indoors or outdoors. The metal letter shells are made from 304 stainless steel by default, marine-grade 316 for coastal outdoor sites, and aluminum on large letters to cut weight. Every set is built to your exact design, so it truly fits your needs.
Common applications and related pages
Backlit channel letters are widely used on storefronts, brand walls, office reception areas, restaurants and hotels, and building facades, both indoors and outdoors. Here are a few typical industries where they are applied.
A well-made set of channel letters with a strong glow makes your storefront easier to spot and remember from the sidewalk. Signs do bring customers: in a national survey, 76% of consumers had walked into a store they had never visited before because of its signage (per FedEx Office)1.
What we need for your custom project
- Design file
- A vector file is best. A high-resolution raster or an AI-generated flat image also works for a quote. Do not auto-trace a raster into a vector with software: much of the detail is lost, so send the high-resolution raster instead.
- Property sign rules
- Before any design work starts, check the sign rules with your property, landlord, or property manager: the allowed size range, any finish or color requirements, light color temperature limits, and the required mounting method. If the property has written sign criteria, send them to us directly, and both the quote and the shop drawings will follow them.
- Sizes
- Stay within the sign size range your property allows. Readability sets the floor: in a national shopper study, 90.9% agreed that sign letters should be large enough to read from a passing car (per BrandSpark)3. If your sign serves as or includes address numbers, the U.S. model building and fire codes (IRC R319.1 for residential, IFC and IBC 505.1 for commercial) set a minimum for address numbers: a model-code floor of about 4 inches (102 mm) in height and a 0.5 inch (12.7 mm) stroke width5. Some jurisdictions require larger, so always follow your local rules.
- Wall
- Send a photo of where the backlit channel letters will be installed, so we can plan the right mounting method and advise on the light color temperature.
- Power
- Tell us the power available (AC or DC) and the voltage, so we can match the right Mean Well power supply for you.
- Indoor or outdoor
- Describe exactly where the sign will be installed, whether indoors, outdoors, or on a coastal site. For an outdoor sign in an extreme climate (high heat, heavy rain, cold, or dust), please tell us before we lock the production details.
- Finish
- Mirror polished
- Brushed
- Vibration finish
- Painted or powder-coated color, in gloss, semi-gloss, or matte (tell us the exact color and we color-match to Pantone, RAL, SW, or MP swatches)
- Plated metal colors (gold, black titanium, copper, and more)
- Special effects such as wood grain, antique, and marble look
- Light color
- White
- Warm white
- Red, yellow, blue, or green
- Adjustable color (RGB / WRGB)
Choosing your model: Luxury or Common
Backlit channel letters come in two models, Luxury and Common. See the point-by-point comparison in Compare below.
Luxury model
- Opal acrylic backing panel partly exposed, with a stronger halo
- Mounts flush or nearly flush to the wall
- Best for premium storefronts and brand walls
View Luxury Model Common model
- Opal acrylic backing panel hidden inside the metal letter shell
- Mounts about 3/8 to 3/4 in (10 to 20 mm) off the wall
- Suits storefronts, large letters, curved walls, and outdoor sites
View Common Model Installation and electrical
Installation
- We recommend a professional installer: the job involves drilling the wall, setting stud bolts, routing wires, placing the power supply, and low-voltage wiring.
- We provide the 1:1 template, the wiring diagram, and the installation instructions.
- The Common model usually needs off-wall mounting for the reflected halo to form.
Power supply
- The power supply usually sits behind the wall or above the ceiling.
- The Mean Well power supply needs a spot that can shed heat and stays accessible for service.
- For U.S. projects, we plan a 12V DC low-voltage system with a UL Listed power supply before production.
Outdoor planning
- 304 stainless steel by default; marine-grade 316 for coastal or near-coast sites.
- In rainy regions we plan waterproof LEDs and drainage holes, and we detail the edges to prevent light leaks.
Backlit channel letters FAQ notes
- How do I set the letter height?
- Within the sign size your property allows, start from the viewing distance. As a rule of thumb, a letter stays readable up to about 120 times its height (for example, a 1-inch letter reads clearly within about 10 feet), though stroke width and ambient light matter too.
- How do I set the overall size?
- Within the size your property allows, and to keep a balanced look, we usually use the golden ratio or a half-width relationship, so the sign width is roughly 38.2%, 50%, or 61.8% of the wall width.
- Which fonts work well?
- Readable fonts with enough stroke width are the safe choice. Very thin, highly decorative, or tightly spaced fonts reduce readability and manufacturability.
- Can they be customized?
- Yes. We customize to your brand name, logo, brand colors, finish direction, light color, sizes, and installation conditions.
- Can they go outdoors?
- Yes, but confirm climate exposure, wall conditions, waterproof LED planning, drainage, and material choice early.
