Key Features of Flexible Tunable White LED Light Sheet
1. Smooth Tunable White Lighting from 2700K to 6500K
This tunable white LED light sheet provides seamless color temperature adjustment from 2700K warm white to 6500K cool white, allowing users to create different lighting atmospheres with a single lighting system. From warm ambient illumination to bright daylight-style lighting, the sheet adapts easily to changing commercial and architectural lighting requirements.
2. Flexible FPC Design for Flat and Curved Installations
The high-quality flexible FPC board can be installed on flat, curved or irregular surfaces without sacrificing lighting performance. Whether used in round light boxes, custom-shaped displays or architectural features, the flexible construction allows greater design freedom while simplifying installation.
3. Single LED Cuttable for Fully Customized Layouts
Featuring a 24 × 24 mm cutting unit, each LED section can be cut individually to fit custom dimensions. This flexible cutting capability reduces installation waste and enables quick adaptation for irregular light boxes, decorative panels and bespoke commercial lighting projects.
4. OEM & ODM Customization from a Professional Manufacturer
As an experienced LED light sheet manufacturer, YESUN offers OEM and ODM customization, including custom FPC sizes, color temperatures, voltages, LED layouts, connectors and packaging. Our engineering team works closely with customers to develop lighting solutions tailored to commercial signage and architectural lighting projects.

Connection Methods and Installation Guide for Flexible Tunable White LED Light Sheet
Our LED light sheets support two standard wiring configurations to fit projects of all sizes, with additional scalable solutions available for large-area installations. Both core setups are quick to install using the matching accessories below.
Method 1: Cascade connection Connection (Figure 1)
Ideal for compact layouts with a small number of LED light sheets.
1. Plug one end of the sheet-to-power connection wires into the terminal of an LED light sheet, and connect the opposite end to your power supply.
2. For multi-sheet setups: Use sheet-to-sheet connection wires to link the adjacent terminals of two LED light sheets. Repeat this step to cascade connection additional sheets in sequence.
Important Notice: The maximum cascade connection quantity per single circuit varies by product model. For DC 12V or 24V systems, always verify the exact limit in the product’s technical specifications. Exceeding this rating will cause noticeable voltage drop, uneven brightness along the run, and risk of power supply overload. For larger installations, upgrade to a higher-wattage power supply, use the branch wiring method below, or deploy multiple power supplies for zoned independent power delivery.
Method 2: Main Cable Branch Connection (Figure 2)
Recommended for large-area installations with a high volume of LED light sheets, to ensure stable performance and consistent light output across the full space.
1. Connect the main trunk line of the main cable connector to your power supply.
2. The main cable connector features multiple tap outputs to form independent branch circuits.
3. On each individual branch, follow the cascade connection steps from Method 1 to connect your LED light sheets separately.
This distributed wiring design minimizes long-run voltage drop and avoids overloading a single circuit. Note that this is not the only high-capacity solution — using multiple power supplies for zoned independent power is also a standard, reliable approach for extra-large or multi-zone projects.
Flexible Tunable White LED Light Sheet for Cutting Matters and Suggestions
Our FPC LED light sheets can be trimmed to custom dimensions to fit your installation layout. Follow the guidelines below to avoid damaging the internal circuit and ensure normal operation.
✅ Valid cutting (left panel): Both straight cuts (horizontal / vertical along grid lines) and diagonal cuts are allowed, as long as you trim along designated unit boundaries to retain complete LED circuit groups. The diagram demonstrates correct diagonal cutting examples; straight perpendicular cuts along the grid also follow this valid cutting rule.
❌ Invalid cutting (right panel): Cutting through incomplete circuit units, or trimming a diagonal strip with only 1 LED group, will break the internal circuit and cause partial LEDs to malfunction.
Important Precautions
1. Cutting Unit Rules
• For straight cuts (horizontal or vertical along the grid lines, i.e. positive-direction cutting), the minimum valid cutting unit is 1 complete LED group.
• For diagonal cuts, the trimmed section must contain at least 2 complete LED groups. Cutting a single diagonal LED strip will break the internal circuit and cause LED failure.
• Always cut slightly beyond the marked cutting line for a clean full cut. Avoid cutting through connector positions whenever possible.
2. Cutting Operation
• Use sharp scissors and cut firmly through the full thickness of the FPC sheet. Trim away any burrs on cut edges before installation.
3. Installation Requirement
• Leave a 1–2 mm gap between adjacent cut FPC sheets during assembly. The sheets must not come into direct contact with metal surfaces.
3. Edge Insulation
• Seal and insulate all cut edges and exposed solder pads with insulating tape or adhesive to prevent short circuits.

Recommended Applications for Flexible Tunable White LED Light Sheet
1. Premium Light Boxes with Adjustable White Lighting
Unlike fixed-color light sheets, the tunable white LED light sheet allows users to switch between warm and cool white illumination, making it ideal for retail light boxes, luxury brand displays and commercial advertising where different lighting moods are required throughout the day.
2. Luminous Ceilings and Stretch Ceiling Systems
Designed for backlit ceilings, stretch ceilings and luminous architectural panels, this product provides soft, uniform illumination across large ceiling areas. Adjustable white lighting allows hotels, shopping malls, offices and hospitality venues to create different lighting environments for daytime and evening use.
3. Backlit Marble, Onyx and Translucent Stone
The adjustable color temperature enables designers to highlight different textures and colors of marble, onyx, quartz and translucent decorative stone. Warm white lighting creates a luxurious atmosphere, while cool white enhances the natural details of the material, making it perfect for reception desks, feature walls and illuminated furniture.
