Readability
Letter height, face color, return contrast and background all affect how quickly the sign can be read. Review the layout at the main customer approach instead of judging it only on a flat proof.

When you buy from a trading company, you pay a middleman and wait on someone else's production line. When you buy from SignLumi, you talk directly to the factory that cuts, welds, assembles and wires your signs.
Front-lit channel letters illuminate the face while the return defines the letter shape. This construction is often selected when the name must be recognizable quickly from the street, sidewalk or parking area.

The acrylic face controls how the light is diffused and how the color appears when the sign is switched on and off. Approve the color and finish in the intended lighting.
Confirm the supply, driver location, timer or switch, and service access before fabrication. The installation plan should match the building's electrical arrangement.
Exterior signs need sealed LED modules, weather-rated wiring and a finish suitable for rain, heat and the local environment. Confirm these details in the bill of materials.
Confirm who prepares the wall, power connection and switching point. The factory should provide clear fixing information and label the letters for the installer.
| Decision | What to compare | What to send |
|---|---|---|
| Letter size | Height, width and viewing distance | Facade photo and dimensions |
| Face | Acrylic color, diffusion and finish | Logo color and sample reference |
| Return | Metal type, depth and finish | Mounting surface and recess limits |
| Power | Driver location, switch and timer | Electrician site notes |
| Service | Face or module access | Maintenance requirements |
Indoor letters run about 30mm; outdoor storefronts use 50–80mm. Deeper bodies hold more LED modules for brighter, more even light, so we recommend 80mm once letters exceed 24 inches tall.
There is no single size that fits every storefront. Letter height depends on the viewing distance, facade width, surrounding signs and required message. Provide a facade photo with dimensions so the layout can be evaluated at the intended distance.
Serviceability depends on the construction and installation. Ask how the face and LED modules can be accessed, where the driver will be located and whether replacement components can be supplied.
Our standard setup reaches 800–1200 cd/m² across the face — readable in full sun. We can raise or lower LED density to suit the location and your preference.
Yes. We tint the acrylic face to any RAL, Pantone or physical sample you send, and powder-coat the aluminum returns to your trim colour.
