24V LED SHEETS · SINGLE-COLOR & RGBW
These 24V LED backlight panels are LED PCB sheets for stone backlighting. Each 240 × 480 mm sheet has 288 LED packages. Compare the 2835 single-color and 5050 RGBW versions, then plan the layout, wiring and light cavity around your stone installation.
Press R, G, B or W to preview the panel in red, green, blue or white.
White light · W selected
RGBW version preview. W represents the white channel, not RGB mixing. LED positions and glow are illustrative; actual appearance depends on the selected panel, stone and installation. Buttons operate this preview only.

Review the inputs needed to start
↓APPLICATION FIRST
Use the single-color version for a consistent lighting tone, or the RGBW version for red, green, blue and white lighting channels. Select the white-light color temperature and control method with your project brief. The finished appearance still depends on stone transmission, thickness, diffusion and LED-to-stone distance.
01 / COMPARE THE PANELS
Two confirmed configurations for a stone backlighting brief. The LED count refers to complete LED packages per sheet, not the number of chips inside a package.
One lighting color for a consistent appearance.
Specify the desired color. For white-light projects, confirm CCT and CRI before ordering.
Discuss single-color panels →Color lighting with a separate white channel.
RGBW is not dual-CCT. Confirm the white-channel CCT, channel loads and compatible controller.
Discuss RGBW panels →02 / PLAN THE FINISHED SURFACE
Use an actual stone sample to agree on the appearance before committing to a full installation.
Record stone type, thickness, translucency, veins and visible area. Opaque areas will not behave like translucent ones.
Trial the LED-to-stone spacing and any diffuser or reflector. Check hotspots, edges and joints using the intended viewing distance.
Confirm measured or rated load, cable lengths, feeds, dimming and heat dissipation. For RGBW, review the load of each channel.
Coordinate supports, openings, connectors and service access. Confirm permitted cutting and connection points before modifying a sheet.
Include the illuminated dimensions, cavity depth, panel choice, desired white tone or color effects, quantity and control requirements.
DEFINE BEFORE DESIGN
Confirmed requirements, preferred targets, and open questions can all be included in the first brief. Unknown values stay visible until they are reviewed.
Material, thickness, dimensions, transmission variation, cutouts, edges, and the areas that must remain uniform.
LED-to-stone distance, diffuser or reflector, internal surfaces, viewing distance, and acceptable hotspot level.
CCT, CRI, brightness, color consistency, dimming range, and the agreed evaluation method.
Panel size, board shape, LED spacing, modular joints, keep-outs, mounting, and replacement access.
Input, driver, circuits, current, wiring length, voltage drop, heat path, ambient, and duty cycle.
Connectors, polarity, cable route, supports, serviceability, moisture, enclosure, and installer instructions.
PROJECT FIT
Each stone installation needs its own panel geometry, optical spacing, drive, thermal path, wiring, and service plan.
Custom panel geometry coordinated with supports, openings, edges, and service access.
Modular coverage, wiring routes, dimming, uniformity, and installation sequence.
Compact cavities and thermal constraints reviewed with the visible stone surface.
Shape, brightness, touch or dimming control, wiring, and replaceable module design.
CONTROLLED DEVELOPMENT PATH
A review result, prototype, or sample remains a project stage. Production begins only from the information and acceptance criteria approved for that project.
Confirm geometry, electrical input, optical target, thermal conditions, quantity, and the available source material.
Define the board, emitter arrangement, drive conditions, connections, mounting, and prototype route.
Review the agreed electrical, optical, thermal, mechanical, and safety-related acceptance points.
Carry the confirmed design, BOM, assembly, inspection, labeling, and packing information into production.

PROJECT QUESTIONS
These answers describe how a project can begin. They do not promise an unreviewed specification, performance result, certification, schedule, or price.
Both are 24V, 240 × 480 mm and have 288 LED packages per sheet. The single-color version uses 2835 LEDs; the RGBW version uses 5050 LEDs. RGBW means red, green, blue and white, not tunable white.
This page shows LED PCB sheets used as light sources for stone backlighting, not a complete lightbox or light-guide panel. Stone, diffusers, power supplies and controllers are not implied inclusions; confirm the supply scope in the quotation. Custom-size requests require a separate feasibility review.
Rated wattage and current have not yet been specified. Confirm the selected version and operating conditions before sizing the power supply, controller or wiring. Do not calculate power from LED count alone.
Spacing depends on stone transmission, thickness, cavity depth, diffuser or reflector, LED optic, drive level, viewing distance, and the accepted uniformity target. Samples or mockups are often needed.
Custom board outlines or modular arrangements can be evaluated against manufacturing limits, support points, wiring, thermal path, installation, and service access.
They can be included as project targets. LED selection, binning, operating current, optics, stone variation, driver, tolerance, and measurement method must be confirmed.
Send stone dimensions and thickness, photos or samples, cavity depth, support and opening drawings, desired appearance, power and dimming needs, installation method, quantity, and target date.
