What are front-lit letters?
Front-lit acrylic letters are built-up 3D letters whose faces are made of translucent acrylic. LED modules inside each letter light the face, so the whole letter glows evenly. They are the most readable illuminated sign at night, which is why they are the standard choice for shopfronts, mall storefronts and building fascias.
Each letter is a small, sealed light box: an acrylic face, a metal or acrylic return around the edge, and a back panel holding the LEDs. We cut faces and returns to your artwork, assemble and light every letter in our workshop, and check it for even glow before it leaves for site.
Where it works
- Shopfront and fascia signs on the high street
- Mall storefronts where the brand must hold its own against neighbours
- Building-top and name signs that need to be read from a distance
- Showroom frontages and indoor feature walls in brand colours
Material options
- Faces: opal white or coloured acrylic. For an exact brand colour we can apply translucent vinyl over a white face.
- Day/night film: a special film that looks dark in daylight and glows white when lit, useful when a brand wants black letters by day.
- Returns (sides): aluminium or steel strip, painted to match, or stainless steel and gold PVD for a premium edge. Acrylic returns are used for an all-glowing letter.
- Backs: ACP or acrylic sheet, sealed to keep dust and insects out.
Lighting options
- LED modules are spaced to suit the letter depth so the face glows evenly, without visible spots.
- Deeper returns usually give a smoother glow; very thin strokes need careful module selection.
- Choose warm white, neutral white, cool white or a single colour. Timers and photocell switches can be added.
- Power supplies are placed where they stay ventilated and reachable for service.
Finish choices
- Returns in PU paint matched to your brand colour, brushed or mirror stainless steel, or gold PVD
- Trim cap or trimless (face bonded directly to the return) for a cleaner edge
- Gloss or matte face finish
Care and maintenance
- Clean faces with a soft cloth and mild soap solution. Avoid thinners, alcohol and strong solvents, which can crack acrylic.
- Outdoor letters have drain holes; keep them clear after the monsoon.
- LED modules and power supplies can be replaced individually if one fails.
- An occasional check of fixings and wiring is sensible on exposed façades.
What affects the cost
| Factor | Why it matters |
|---|---|
| Letter height and number of letters | Larger and more letters use more material, LEDs and labour |
| Return depth and material | Stainless steel or PVD returns cost more than painted aluminium |
| Face treatment | Applied vinyl, day/night film or special colours add cost |
| Lighting and power | More LEDs and power supplies for larger or brighter letters |
| Mounting height and access | Ladders, scaffolding or lifts may be needed |
| Site timing | Malls often allow work only at night or in fixed windows |
Common questions
Are front-lit acrylic letters suitable for outdoor use?
Yes. Outdoor letters are sealed, fitted with drain holes and use weather-rated LEDs and power supplies. We also choose acrylic and paints that hold up to strong sun.
Can the face match my exact brand colour?
Usually, yes. We either use coloured acrylic or apply translucent vinyl to a white face. We can show you a lit sample of the colour before full production.
