Product Information

This 24V cuttable flexible LED light sheet delivers modular addressable RGBW illumination across a 490 × 245 mm black flexible circuit board. Engineered for uniform backlighting behind translucent stone, acrylic, signage, and architectural features, each sheet incorporates 144 SMD 5050 4-in-1 LEDs grouped into 24 individually controllable pixels. The integrated WS2814B IC provides breakpoint transmission, which prevents a single failed LED from interrupting subsequent signals across your display. Each unit can be field-cut every 6 LEDs along 61.25 × 81.66 mm grid sections to fit custom shapes and irregular enclosures. Four terminal connectors allow rapid daisy-chaining and DC 24V power injection. Pair this unit with an addressable RGBW controller and a regulated MeanWell indoor power supply for smooth dynamic scenes. 

Key Features

WS2814B Breakpoint Resume

Dual data lines allow dynamic control signals to bypass a defective pixel, preserving signal continuity across the remaining panel.

Field Cuttable Grid

Divide the sheet every 6 LEDs into 61.25 × 81.66 mm modules along marked lines to accommodate tight enclosures or irregular geometries.

24 Addressable Pixels

Control 24 separate zones per panel independently to generate scrolling patterns, gradients, and custom chasing sequences.

Four Quick Terminals

Each board features one input port, one output port, and two dedicated power injection ports to minimize voltage drop.

Direct or Standoff Mounting

Mount directly using adhesive backing and pre-punched screw holes, or install with clear PC support pillars for diffusers.

RGB Plus Dedicated White

Combines 16 million RGB colors with dedicated white diodes in 3000K, 4000K, or 6500K for clean pastels and pure white task lighting.

Application Scenarios

Translucent Stone and Countertop BacklightingProvides shadow-free diffusion beneath onyx, quartz, and marble reception desks. The cuttable flexible led light sheet geometry allows installers to navigate sink cutouts and angled perimeters without dark voids.
Curved Signage and Lightbox IlluminationsPaper thin flexible cuttable led light sheet backlight hardware bends smoothly around concave and convex surfaces. Addressable RGBW control allows dynamic chasing effects behind graphic film or fabric stretch ceilings.
Architectural Niches and Showcase DisplaysDelivers uniform area backlighting for luxury retail shelves, museum display cases, and hotel decorative panels. The cuttable led light sheets adapt to custom millwork dimensions via marked cutting grids.

How to Install & Use This LED Strip Light Sheet

  1. Connect the sheet to a DC 24V power supply and a compatible WS2814B controller before adhering to verify color rendering and pixel continuity.
  2. Connect the data input to the controller. When tiling multiple sheets, wire DC 24V power directly into the supplementary injection terminals to prevent voltage drops.

⚠ Precautions

  • Operate strictly with regulated DC 24V power supplies; applying higher voltage will cause immediate component failure.
  • Always calculate power supply capacity with at least 20% operating headroom (e.g., provide 50W driver capacity per 40W sheet).
  • When joining multiple panels in series, inject DC 24V power to prevent voltage drop and color shifting.

Frequently Asked Questions

Q: Can this LED strip light sheet be cut to fit custom dimensions?

A: Yes, you can cut the sheet along the printed grid lines every 6 LEDs into 61.25 × 81.66 mm sections without damaging the remaining pixels.

Q: What is the benefit of the WS2814B breakpoint resume IC?

A: The WS2814B chip incorporates dual data signal lines. If an individual LED chip fails, data automatically routes through the backup line so subsequent pixels stay illuminated.

Q: How do I control the RGBW color effects?

A: You need an addressable SPI controller compatible with the WS2814B protocol, which allows independent control of the RGB diodes and the dedicated white channel.

Q: How do I mount a diffuser panel over the LED sheet?

A: You can stick the sheet directly to a flat backing using the pre-applied adhesive tape, then install clear plastic PC support pillars through the board holes to support an acrylic diffuser.

Q: Can this flexible light sheet be used in damp or outdoor environments?

A: The standard version is IP20 for dry indoor applications. An IP54 coated variant is available for damp indoor areas, but neither model should be submerged or exposed to open rainfall.

Q: What warranty is provided with this product?

A: The FLS24V-WS2814RGBW-144 flexible LED light sheet is backed by a 3-year limited warranty and has an expected operational lifespan exceeding 36,000 hours.
