What Is LED Sheet Light?
LED Sheet Light is a large-area LED lighting panel made with ultra-dense LED chips on a flexible PCB sheet.
It delivers perfectly uniform backlighting without hotspots, even behind thick marble, onyx, acrylic, or retail displays.
Compared with traditional LED strips, LED Sheet Light provides much better uniformity, easier installation, and flexible cutting options.

How to Install LED Sheet Light
1. Clean the installation surface.
2. Peel off 3M tape and stick the sheet.
3. Connect wires (positive / negative).
4. Test illumination and uniformity.
5. Install stone or acrylic cover panel.
6. Add aluminum sheet if additional heat dissipation is needed.
Safety Note:
Always test illumination before installing stone panels.
How to Cut LED Sheet Light
LED Sheet Light can be cut along the printed cut lines without damaging the circuit. You can create L-shapes, curved shapes, or custom sizes depending on the project.
As shown in the figure, horizontal cutting, vertical cutting and oblique cutting can be carried out along the lines on the panel. When cutting, do not cut components by mistake
Always avoid cutting through LED chips or resistors.

FAQ:
Q1: Will LED Sheet Light show hotspots?
No, AiDiWatt LED Sheets are designed with ultra-dense LEDs to ensure perfectly uniform illumination with zero hotspots.
Q2: Can the sheet be bent or curved?
Yes. It can handle gentle bending and can be applied on slightly curved surfaces, making it suitable for creative shapes.
Q3: Is LED Sheet Light suitable for stone backlighting?
Yes — LED Sheet Light is the best solution for backlighting onyx, marble, jade, and resin panels due to its thin profile and uniform plane-light output.
Q4: Can I order custom sizes or shapes?
Yes. We provide custom shapes, sizes, cut-outs, and layouts based on your project requirements.
Q5: Is waterproof protection available?
Yes. IP54 and IP65 versions are available upon request for semi-outdoor or humid environments.
Q6: How do I choose the correct wattage?
Thicker or darker stone requires higher wattage.
Thin or translucent stone can use lower wattage.
If you’re not sure, share your stone photo and thickness — we will recommend the best wattage.
Q7: How many sheets do I need for my wall or panel?
Measure the total illuminated area (width × height), then divide by the usable sheet area.
For example:
A 3m × 1.2m wall = 3.6 m²
One 480×240 mm sheet ≈ 0.115 m²
So you need about 32 sheets.
Send us your drawing, and we can calculate the exact quantity for you.
Q8: What power supply should I use?
Use a constant-voltage power supply that matches the sheet voltage (24V/36V/48V).
Choose a power supply with at least 20–30% extra capacity above total wattage for stable performance.
Q9: Can LED Sheet Light be dimmed?
Yes. It supports PWM dimmers, 0–10V dimming, TRIAC dimming, DALI dimming, and smart controllers depending on your power supply.
Q10: Can I cut the sheet myself?
Yes. Sheets can be cut horizontally, vertically, or diagonally along the printed cut-lines without damaging the circuit.
Avoid cutting outside the marked lines.
Q11: Can I connect multiple sheets together?
Yes. Sheets can be daisy-chained using the included connectors, allowing large-area installations with uniform brightness.
Q12: What is the lifespan of LED Sheet Light?
Typically 50,000–100,000 hours, depending on wattage and heat management.
Adding an aluminum backing can extend lifespan.
Q13: How thick is the LED Sheet Light? Will it fit behind stone?
The sheet is only 2–4 mm thick, so it fits into shallow cavities behind onyx and marble panels even when space is limited.
Q14: What color temperatures and versions are available?
We offer:
Single CCT (2700K–6500K)
Tunable White
RGB
RGBW
SPI-RGBW addressable pixel version
All in the same ultra-thin plane-light format.
Q15: Can LED Sheet Light be used continuously 24/7?
Yes. AiDiWatt LED Sheets are built for long-term commercial operation in hotels, bars, retail stores, and signage applications.
Ensure proper ventilation and appropriate power supply.
