Classic 128 LED Light Sheet – Even Backlighting for Awkward Shapes
Some signs and displays will not take a strip or a rigid module. Curved reception fronts, shallow lightboxes, irregular shapes cut to a template. The Classic 128 LED Light Sheet is built for exactly those jobs: a thin flexible panel that lights evenly across its whole face and can be cut and shaped to fit.
Here's how it works: 128 surface-mount 2835 LEDs sit on a flexible PCB behind 175° wide-angle lenses. The wide lenses spread each LED's output so the panel reads as one even sheet of light rather than a grid of dots, even close behind diffuser. Power clips onto a terminal at the panel edge; further panels link off it with Jumper Cables.
Why it matters: Uneven backlighting is the fastest way to make a professional sign look cheap, visible hotspots, dark bands between LEDs, bright corners. A wide-angle sheet at the right depth removes that problem, and because it flexes and cuts, one product covers shapes that would otherwise need custom fabrication.
Buying singles or a 4-pack? The connectors differ, read this first:
-
4-pack: arrives complete, 4 sheets plus 1 Power Cable and 5 Jumper Cables included. Ready to install as a linked run, nothing else to add.
-
Individual sheets: you receive the sheet only, no connectors. Buy a Power Cable (one per run, feeds up to 10 sheets) and a Jumper Cable for each join between panels.
Connectors are only included with full 4-packs. Loose single sheets do not come with any.
Key Advantages
-
175° ultra-wide beam – Lenses spread the light so there are no visible LED hotspots, giving even illumination at shallow depth behind a diffuser.
-
Flexible PCB, 25mm bend radius – Wraps around pillars, curved desk fronts, and architectural curves without damaging the board or LEDs.
-
Cuttable at every LED – Marked cut lines at each LED position let you trim panels to irregular shapes and exact lightbox sizes.
-
Edge connection, links up to 10 panels – Power enters at a panel edge; further sheets daisy-chain off it, up to 10 panels on one supply.
-
High efficiency, over 130 lm/W – Over 2,800 lumens at just 24W per sheet, so a multi-panel sign stays within a sensible driver size.
Perfect Applications
-
Lightbox illumination – Even edge-to-edge light for signage, menu boards, and display cases where build depth is tight.
-
Curved surface backlighting – The flexible panel wraps pillars, curved walls, and shaped architectural features a rigid board cannot follow.
Also ideal for reception desk features, retail shelf and cabinet lighting, exhibition graphics, and architectural accent lighting in commercial and hospitality interiors.

Product Supply Options
Available as individual sheets or as a value 4-pack. What you receive in the way of connectors depends on which you buy, so check this carefully before ordering.
What's In the Box
If you buy a 4-pack of sheets:
- 4 x Classic 128 LED Light Sheets (503mm x 240mm)
- 1 x Power Cable – feeds the run from your 24V supply
- 5 x Jumper Cables – link the sheets together
A 4-pack arrives ready to install as a linked run. No separate connector order needed for a standard 4-panel job.
If you buy individual sheets (any quantity that is not a full pack multiple):
- The sheet only. No Power Cable or Jumper Cables are included.
- Connectors are bought separately to suit your layout: one Power Cable per run (feeds up to 10 sheets), plus one Jumper Cable for each join between panels.
In short: Full 4-packs come with all the connectors for that pack. Loose single sheets come with no connectors. If you are buying singles and linking them, add a Power Cable and the right number of Jumper Cables to your order.
What's Not Included:
- 24V DC power supply – Required for operation. Size it to total load (24W per sheet) with headroom. Browse 24V Power Supplies.
- LED dimmer / controller – Optional, for brightness control. Must be 24V DC and rated for total system wattage. Browse LED Dimmers & Controllers.
- Connectors when buying single sheets – Power Cable and Jumper Cables sold separately (see above).
- Mounting accessories – The rear adhesive suits most clean, dry surfaces; additional clips or channels are available if adhesive is unsuitable.

What This Actually Is
A flexible printed circuit, roughly A4-ish in size, carrying 128 LEDs behind wide-angle lenses, with a sticky back and edge power terminals. It behaves like a sheet of even light that you can bend to a curve and cut to a shape.
In Plain English: A bendy, stick-on light panel about the size of a sheet of A4, that you can trim with scissors and link to more panels. One 24V supply runs up to 10 of them.

Cutting & Customisation
The sheet has cut lines at every LED position. Trim along the marked lines with sharp scissors or a craft knife to fit irregular shapes or exact lightbox sizes. A cut section needs a new power connection point on the piece you intend to keep powered. Seal cut edges if there is any moisture risk, though note this is an IP20 panel for dry indoor use only.
Installation & Compatibility
- Mounting: Pre-applied adhesive on the rear. Fix to a clean, dry, smooth surface. No extra hardware needed for most installs.
- Power connection: Clips onto the panel edge terminal using the Power Cable. Further panels link with Jumper Cables.
- Compatible supplies: Any 24V DC constant-voltage LED supply, sized above total load. A 4-panel run is 96W (use 120W minimum); a 10-panel run is 240W (use 300W).
- Compatible dimmers: Any 24V DC PWM or 0-10V dimmer rated for total system load.
- Maximum chain: 10 panels per supply feed. Larger installs need multiple power zones, the technical team can plan distribution.
Quality Notes
- Batch consistency: Sheets ordered together are matched from one production batch for consistent colour. Sheets bought at different times may vary slightly in tone.
- Driver sizing: Always size the 24V supply above total load. 24W per sheet x panel count, then up to the next sensible supply rating.
- Professional installation: For commercial or complex multi-panel arrays, professional installation is recommended to get power distribution and panel matching right.
