Lightbox Signage
Lightbox signage is the most cost effective way to get a large, bright, evenly lit sign, which is why it remains the most common illuminated signage in Singapore. A sealed box, an illuminated face carrying your artwork, and LEDs inside. We build custom light boxes in any size and shape from our own workshop, including projecting and double sided units.
What is lightbox signage?
A lightbox is a sealed aluminium frame with a translucent face on the front, LEDs mounted inside, and your artwork either printed onto the face or applied as cut vinyl. When lit, the whole panel glows evenly and the graphics read as dark or coloured shapes against a bright background, or the reverse. It can be single sided and flush against a wall, or double sided and projecting out from a frontage so it is visible along the street.
Its advantage over individually made letters is simple economics. Because you are illuminating one continuous panel rather than fabricating and wiring each character separately, you get far more lit area for your money. Its disadvantage is that it reads as a panel rather than as lettering, which is less refined than frontlit channel letters. For most retail, F&B and service businesses that trade-off is worth making.

Why lightboxes remain the default
Where lightbox signage works
Wherever brightness, size or changeable artwork matters more than sculpted lettering.
Acrylic face or flex face, and when each is right
Two face materials cover almost all lightboxes and they behave quite differently. Acrylic is rigid, holds a crisp printed image, and gives a clean flat surface. It is the standard choice up to roughly two metres, beyond which large acrylic sheets become heavy, expensive and prone to bowing in heat.
Flex face, a tensioned PVC fabric stretched across the frame, takes over for larger formats. It is lighter, cheaper per square metre at size, and can be removed and re-tensioned. The trade-off is that it is slightly less crisp up close and can develop a soft ripple over years if the tensioning is not maintained. For a sign viewed from twenty metres, neither matters.
For most shopfront work under two metres wide, acrylic is the better product. For a long fascia running the width of a unit, flex face is usually the sensible answer. We will tell you where the crossover falls for your particular dimensions rather than defaulting to one.
Why cheap lightboxes look patchy
The most common complaint about lightbox signage is visible banding: bright stripes where the LED strips sit and darker bands between them. It happens when the box is too shallow for the LED spacing used, so the light has not spread and merged by the time it reaches the face.
Depth is the main lever. A deeper box gives light room to diffuse, so modules can sit further apart and still produce an even wash. Slim boxes, which are popular because they look neater against a wall, need either much tighter LED spacing or edge-lit panels with a diffuser sheet, both of which cost more. Buying a slim box at a standard-box price is usually how people end up with banding.
The second factor is face diffusion. An opal or diffusing face hides the light source; a clear or lightly tinted face shows every LED behind it. We specify depth, module spacing and face diffusion together for each box, and test light every unit fully assembled before it leaves us.
Refacing an existing lightbox
If you have taken over a unit with a lightbox already in place, or your branding has changed, you very often do not need a new sign. The box, the frame, the wiring and the mounting are usually the expensive parts, and they are also the parts that last. Replacing just the face is a fraction of the cost of a new build.
Refacing is also the moment to deal with old lighting. Many existing lightboxes in Singapore still run fluorescent tubes, which draw considerably more power than LEDs, fail more often, and dim unevenly as they age. Converting to LED at the same time as a reface typically cuts running cost substantially and removes the recurring tube replacement.
We will assess honestly whether the existing frame is sound. If it has water ingress, corrosion in the housing or a failing structure, refacing good money onto a dying box is not worth it, and we will say so.
Specification choices
These six decisions set the price and the quality of the finished lightbox.
- Configuration: single sided flush mounted, or double sided projecting from the wall
- Face material: acrylic for crispness up to around two metres, flex face for larger formats
- Box depth, which is the main factor in achieving even illumination
- Face graphics: full colour printed, or cut vinyl applied to a coloured face
- Frame finish: powder coated to a brand colour, or standard anodised aluminium
- Control: switched, timer, or photocell so the box lights itself at dusk
If you want sculpted lettering rather than a lit panel, compare frontlit signage and acrylic signage, or see everything on the signage Singapore hub.
What lightbox signage costs in Singapore
Lightboxes are priced largely by area, with depth, face material and whether the unit is double sided as the other main factors. They give more lit area per dollar than any other illuminated option.
| Small boxes and menu panels | from around S$300 to S$700 | Compact single sided units, menu boards, poster frames and small interior lightboxes. |
| Standard shopfront fascia boxes | around S$800 to S$2,800 | Full width single sided fascia panels and most double sided projecting blade signs. |
| Large format and pylon faces | S$2,500 to S$5,000 and above | Large flex face installations, multi-panel directories and illuminated pylon or totem structures. |
Budgeting ranges rather than quotes. Refacing an existing box costs considerably less than any of these, so if you already have a lightbox it is worth asking. Site visits and assessments are free.
How we work
Four stages, whether it is one menu panel or a full shopfront fascia.
Why Creative Sign for lightboxes
Lightboxes are the easiest signage to build cheaply and the easiest to get wrong. Underspecify the depth or stretch the LED spacing and you get banding. Skip drainage on an exterior box and water sits inside it. Use a face with too little diffusion and every module shows through.
We specify depth, spacing and face diffusion as one set of decisions rather than separately, and test light every box assembled before it ships. If you already have a box in place, we will always tell you when refacing is the better value than replacing.

Licensing, insurance and warranty
Every lightbox is mains connected, so the electrical work is part of the job rather than something to hand off. We are BCA-LEW licensed and make the final supply connection ourselves, which matters most on projecting and exterior units where the wiring route is not trivial.
Public liability insurance covers all on-site installation. Fabrication is warranted for 12 months and installation for 6 months, written into your quote. Where we reface or convert an existing box rather than building new, the same warranty applies to the work we carry out, though it cannot extend to the existing frame we did not build.

- Refacing and LED conversion warranted on the work performed
Frequently asked questions
How much does a lightbox sign cost in Singapore?
Small boxes and menu panels start around S$300 to S$700. Standard shopfront fascia boxes and projecting blade signs run roughly S$800 to S$2,800. Large flex face and pylon work goes from S$2,500 upward. Lightboxes give more lit area per dollar than any other illuminated signage, which is why they remain the most common choice.
Can I change the artwork later without replacing the sign?
Yes, and this is one of the main reasons to choose a lightbox. The face is replaceable while the frame, LEDs, wiring and mounting stay in place. Refacing costs a fraction of a new sign, which makes lightboxes well suited to businesses whose branding, menu or promotions change.
Why do some lightboxes have visible stripes when lit?
That banding happens when the box is too shallow for the LED spacing used, so light has not merged before it reaches the face. Deeper boxes let light spread evenly. Slim boxes need much tighter LED spacing or edge-lit panels with a diffuser, which costs more. Face diffusion matters too, since a clear face shows the modules behind it.
Should I choose acrylic or flex face?
Acrylic up to roughly two metres, flex face beyond that. Acrylic is rigid and crisper up close but gets heavy, costly and prone to bowing at large sizes. Flex face is lighter and much cheaper per square metre at scale, at the cost of being slightly less sharp on close inspection. We will tell you where the crossover sits for your dimensions.
Can you convert my old fluorescent lightbox to LED?
Yes, and it is usually worth doing. Fluorescent tubes draw considerably more power, fail more often and dim unevenly as they age. Converting to LED typically cuts running cost substantially and removes recurring tube replacement. It is commonly done at the same time as refacing, since the box is open anyway.
Can lightboxes be double sided?
Yes. Double sided projecting or blade signs mount perpendicular to the wall so they are readable by people walking along the street rather than only those facing your frontage. They are one of the most effective formats for shophouse rows and corridor units. Note that projecting signs are more likely to need landlord or authority approval.
Are lightboxes suitable for full outdoor exposure?
Yes, with the right build: a sealed aluminium frame, UV stable face material so colour does not fade, drainage so water cannot pool inside, a weatherproof driver housing and corrosion resistant fixings. Drainage is the one most often skipped on cheap exterior boxes and the one that causes the most failures.
How long does a lightbox last?
The frame typically lasts many years, and LED modules commonly run beyond 30,000 hours. The face is what ages visibly, through UV fading rather than mechanical failure, and it is also the cheapest part to replace. A well built box is usually refaced two or three times over its life rather than being replaced.
What warranty and insurance do you provide?
Every sign we make carries 12 months warranty on fabrication and 6 months on installation, and those terms are stated in writing on your quote rather than left implied. We also carry public liability insurance for all on-site work, including installations needing scaffolding or a boom lift, and we are BCA-LEW licensed, so any mains connection is made by our own licensed electrical worker.
