Mounting an LED or neon shop sign

“Neon sign Singapore” and “custom neon sign Singapore” are mostly workshop searches. Studios bend glass or plot LED flex onto acrylic. That workshop is not this catalogue. The visit we price, and the price is quote on inspection, is fixing the finished panel to a wall or a window bay and connecting it to a suitable supply. If you do not yet have the panel, the maker’s quote stays the maker’s quote.

The two lamps are easy to confuse in a photo and different on a ladder. LED neon flex is a diffuse strip in a silicone jacket, set into a groove or stuck to a clear sheet, fed by a low-voltage driver. It is what most new shop “neon” actually is. Glass neon is a tube on fire-rated supports, with a transformer that steps mains up. Glass breaks, the transformer is heavier, and the cable is not something to tuck behind a curtain. Both can be made to stay steadily lit. Both can also be programmed to flash. The programme is the legal problem, not the word neon.

BCA’s prohibited list includes advertising signs and signboards illuminated by flickering, flashing and running lights, except certain streets along Orchard Road, Bras Basah and Bugis, and Chinatown on New Bridge Road and Eu Tong Sen Street. BCA tells you to use URA’s circulars for the boundary of those areas. Outside those boundaries a chasing border is not a style choice. HDB’s shop A&A page says only non-flickering lighting is allowed and gives neon as the example, which means a steady neon, not a flashing one. A condo residential facade is a worse place for it: BCA prohibits advertising signs on residential buildings and on the residential component of mixed-use buildings.

Curtains, blinds and roller shades are not part of this booking.

LED flex on an acrylic panel is mounted like a light letter: stand-offs or a French cleat into structure, not picture hooks. The panel is light until the driver and the cable are added, and people under-anchor it. The driver is the heavy, hot part. It belongs in a ventilated box you can open, or on the panel where the maker left a pocket with air, not in a sealed ceiling with the insulation packed against it. Good work leaves a drip loop on the cable so water on the window does not run into the driver. Sloppy work leaves the driver on the floor of the display, the flex peeling at the corners because the adhesive was applied to a dirty acrylic, and a USB-style connector as the mains.

Glass neon is mounted on its standoffs at the spacing the tube maker used. You do not bend a tube “a little” to fit a shorter window. A tube that is forced onto the wrong centres cracks at the electrode. The transformer is fixed to a non-combustible surface, ventilated, and out of reach of the public. If the window is the only place and the transformer would sit in the customer zone, the sign does not go there. Isolation is a switch that cuts the primary. We do not ask staff to unplug a transformer behind a display every night as the means of isolation.

Mains, when it is a new circuit, is the DB-page sentence S$220 to S$450 and an EMA licensed electrician. A fused spur that already exists, in good condition, is not that sentence. Say which one the photo shows. Low-voltage wiring from the driver to the flex is part of the sign if the maker terminated it. Extending it across a wet five-foot way in bell wire is refused. Outdoors, the driver and any joint need to be in an enclosure suited to weather. An indoor driver under a leaking awning is how these signs die in a monsoon week.

A steady “open” sign inside the glass, in a fully enclosed shop, may fall outside BCA’s outdoor definition. That is a reading of BCA’s words, roofed and not fully enclosed and used by the public, against your actual shopfront. It is not a ruling. If the sign is readable from the five-foot way as an outdoor device, treat it as outdoor until ALS says otherwise. Either way the flicker rule is the one that catches cafes. A sign that flashes the word open is the prohibited behaviour even when the letters are pretty. We will mount a steady sign. We will not enable a chase programme to “make it pop” on a street that is not in the exception.

Say glass or LED flex. Send the panel size and the driver model if it is printed on the label. Photograph the window or wall and the socket or isolator. If the sign flashes in the video you send, say whether you can accept it steady. We will not quote a flashing version for a normal HDB shop or a normal street.

A mall that only allows night work is the mall overnight row when the scope matches, S$380 to S$650 for permit-to-work admin and one hardware fix. Hanging a neon and wiring it is often more than one hardware fix. Expect quote on inspection. Do not add curtains or a roller shade to hide the driver. Those are not part of this booking.

The lamp type and the programme decide the visit. The price does not change that.

Questions a business should ask

Ask the studio and the fitter before the acrylic is cut.

1. Is this glass neon or LED flex?
2. Does any part flash, fade or chase?
3. Which street is the shop on, and is it an HDB shop?
4. Where will the driver or transformer sit, and can it shed heat?
5. Is the mains an existing spur or a new cable?
6. Who holds the EMA licence if the cable is new?
7. Is fabrication already invoiced by the studio?

The same open sign is a different decision in an HDB corridor and on a named exception street.

Read BCA’s prohibited list on the licence page together with HDB’s non-flicker line if the shop is an HDB shop. The exception streets are not a mood board. URA circular DC21-04 is the Central Area outdoor-sign circular BCA’s process sits under for non-conserved Central Area buildings, and it says the application goes to BCA before installation. A neon that is also a large structure can trip the Permit To Use tests on BCA’s supporting page: over 10 square metres on a structure, or a structure 4 metres or higher. Most shop neons do not. A roof-mounted one might, and roof parapet advertising is itself on the prohibited list.

SCDF clause 8.1 exit signs are not a design opportunity for a neon open sign placed in the line of sight of the exit. The clause says decorations or brightly illuminated signs, other than exit signs, must not impair the exit sign. We will not mount a neon that competes with the exit sign. New electrical work is an EMA licensed electrician.

How you're charged

A job that already has a sentence on HomeySG uses that sentence. The hour is not added on top of a band unless the written scope says so. There is no fuel surcharge and no published night premium except the mall overnight row.

No neon or LED-flex band exists. The circuit band is only the new cable, invoiced as electrical work. The sign remains quote on inspection.

Ways to keep the bill smaller

• Order it steady. A programme you must disable after a complaint is a second visit.
• Put the driver where the next person can change it. A sealed ceiling costs more when it fails.
• Use LED flex rather than glass if the lease is short and the window is public. Glass breakage is the maker’s material risk and your downtime.
• Do not buy a sign that is wider than HDB’s front-door limit if you are in an HDB shop. The limit is on HDB’s page: 600 mm high and the width of the shop, for the position immediately above the front entrance.
