LED LIGHT SHEET
Product Overview
Single Color Flex LED Sheet for Stretch Ceilings, Light Boxes & Translucent Stone
Unlike a single strip placed around an edge, a flexible LED light sheet distributes LEDs across the back of a translucent surface. The repeatable 500 x 240 mm module helps project teams estimate sheet quantity, wiring branches and service access before installation.
Verified specifications support lighting brands, project contractors, wholesalers and procurement teams reviewing samples, layouts and quotations for indoor backlighting projects.

PRODUCT FEATURES
Why Choose Our Flexible LED Light Sheet
Review every product feature against the actual material, layout and electrical plan before project approval.
Uniform Full-Surface Backlighting
The 500 x 240 mm sheet distributes 120 SMD2835 LEDs across a backlit area. Confirm the material, cavity and layout with a project sample when light appearance is critical.
- 120 pcs SMD2835 LEDs per sheet
- 500 x 240 mm sheet format
- 2370 lm per sheet
Cuttable Along Marked 20 mm Lines
Plan the final outline and connection points before cutting. The sheet is cut only on its marked 20 mm lines so electrical components and conductors remain intact.
- Cut only along marked 20 mm lines
- Do not cut LEDs, resistors or conductors
- Confirm layout before cutting
Flexible Layout for Indoor Surfaces
Use the sheet as part of an indoor indirect-backlighting layout behind suitable translucent materials. Avoid sharp folds and coordinate fixing, wiring and service access with the finished surface.
- Indoor indirect backlighting only
- Plan fixing and service access
- Avoid sharp folds
Three Project White-Light Options
Specify 3000K, 4000K or 6500K nominal CCT to suit the project brief. CRI 80+ and CRI 90+ are available options; approve appearance behind the actual material.
- 3000K, 4000K or 6500K nominal
- CRI 80+ or 90+ options
- Sample approval for critical appearance
DC24V Constant-Voltage Power Planning
Each sheet uses DC24V, 1A and 24W. Plan the power supply and cable routing for the connected load, cable loss and the project design margin.
- DC24V constant-voltage input
- 24W and 1A per sheet
- Maximum 10 sheets in one connected run
Designed for Shallow Indoor Backlighting
The flexible sheet supports layouts where the project team must work within a shallow indoor cavity. Determine the required installation depth from the actual material, layout and light appearance during sample review.
- 500 x 240 mm modular sheet
- Confirm installation depth with sample
- Dry indoor indirect backlighting

BUYER QUESTIONS
Frequently Asked Questions (FAQs)
Flexible LED light sheet: Expert Q&A
01. Which applications suit this flexible LED light sheet?
This sheet is for dry indoor indirect backlighting, including suitable translucent stone, stretch ceilings, advertising light boxes and custom indoor displays. Confirm the finished material, layout, installation depth and service access for the project.
02. Can it be used for a kitchen island or translucent stone?
Yes, it can be planned behind suitable translucent stone and decorative surfaces for a kitchen island or backsplash. Approve a sample behind the actual material and provide the cavity depth, layout and access details before quotation.
03. What are the cutting rules for the LED light sheet?
Cut only along the marked 20 mm grid. Do not cut LEDs, resistors, conductors or unmarked areas, and confirm the final layout and connection points before cutting.
04. What bending and installation limits should be followed?
Avoid sharp folds and protect the sheet, components and conductors during installation. Use it only for dry indoor indirect backlighting and plan fixing, wiring and service access for the completed installation.
05. Which CCT should I select?
Choose from 3000K, 4000K or 6500K nominal according to the intended white-light appearance. Approve the selected CCT behind the actual material when color appearance is important.
06. Which CRI options are available?
CRI 80+ and CRI 90+ are available options. State the required option in the RFQ and confirm it against the project material and lighting brief.
07. How many sheets can be connected in one run?
Connect a maximum of 10 sheets in one connected run. When the layout exceeds that limit, plan separately designed parallel branches or supplementary feeds with the DC24V power arrangement.
08. How should the DC24V power supply be sized?
Use a DC24V constant-voltage power supply sized for the total connected load, cable loss and the project design margin. Ten sheets equal 240W before cable loss and design margin.
09. Is the sheet for indoor use and what is the warranty scope?
The sheet is for dry indoor indirect backlighting only and has a 3-year indoor warranty from shipment. Keep it protected from outdoor exposure and confirm project conditions before installation.
10. What is needed for samples, drawings and a project quotation?
Share the application, finished material, dimensions, installation depth, CCT, CRI option, sheet layout, power location, quantity, destination and sample requirement. These inputs help prepare a project-specific quotation and sample plan.
