📌 Product Overview
The SF-LED-WW120D-V38 is a 220V AC LED flexible strip series engineered for high-density linear illumination. 💡 Designed with 120 LEDs per meter and an external IC configuration, it targets applications requiring high luminous flux without low-voltage drivers. The series supports Warm White and Daylight spectra with a Color Rendering Index (CRI) of ≥90, ensuring high fidelity for commercial lighting environments. 👇 Design focus should be placed on its 8mm PCB width and IP20 rating, necessitating careful consideration of installation environments to ensure electrical safety and optimal thermal dissipation.
🚀 Typical Applications
- Architectural Coving & Accent Lighting: The 220V input and flexible form factor allow for long-run installations without frequent power injection points.
- Commercial Display & Cabinet Lighting: High CRI (≥90) options ensure accurate color rendering for retail merchandise and exhibits.
- Industrial Linear Fixtures: Suitable for integration into vapor-proof or high-bay fixtures where external drivers add complexity.
- Smart Home Integration: Supports APP, Switch, and Voice control protocols, enabling seamless integration into modern IoT ecosystems.

👇 Critical Process Warning: Do not exceed the maximum run length per power supply connector to avoid voltage drop and uneven illumination.
📏 Package, Dimensions & Assembly Notes
💡 The strip features a standard 8mm width PCB, compatible with most 2-channel aluminum profiles for heat sinking. The "External IC" designation indicates that control components are mounted on the strip surface, requiring a minimum installation depth of 12-15mm within the profile.
- Cutting: Units are cuttable every 100mm (V38) or 50mm (V28), marked clearly on the PCB.
- Mounting: 3M adhesive backing is standard; surface preparation (cleaning/degreasing) is critical for long-term mechanical retention.
- Connectors: Uses 2-wire (2-pin) connectors for power input.
📈 Sourcing & Supply Considerations
- Voltage Configuration: Verify if the target application utilizes 110V/220V AC (V38) or 24V DC (V28) architectures before procurement.
- Control Compatibility: Confirm that the "APP/Voice Control" feature is compatible with the specific ecosystem (e.g., Tuya, proprietary hubs) used in the final product.
- Sample Evaluation: Request CRI binning samples for color-critical projects to ensure batch-to-batch consistency.
- IP Rating: The IP20 rating restricts use to dry, indoor locations unless additional encapsulation is applied by the OEM.
❓ FAQ
Q: Can the 220V version (SF-LED-WW120D-V38) be powered by a battery or standard DC driver? A: No. The "V38" series requires 220V AC mains power. Using DC voltage will prevent the LEDs from illuminating and may damage the components.
Q: What is the difference between the V38 and V28 models in this series? A: The V38 models are high-voltage (220V AC) variants with 8W/m power consumption and 100mm cutting intervals. The V28 models are low-voltage (24V DC), consuming 10W/m with higher CRI (≥98) and shorter 50mm cutting intervals for more flexible layout.
Q: Is this strip suitable for outdoor or wet location lighting? A: The datasheet specifies an IP20 rating. This means the strip has no special waterproofing and is intended for dry, indoor use only. For outdoor use, it must be installed inside a sealed IP-rated fixture or channel.
Q: How does the external IC placement affect the installation profile? A: The ICs are placed externally on the strip surface. While this allows for smart control (APP/Voice), it increases the overall height of the strip. Ensure your mounting aluminum profile has sufficient internal clearance to accommodate these components.
Q: What does "CRI ≥90" imply for the end-user? A: A Color Rendering Index (CRI) of 90 or higher means the light source renders colors very accurately compared to natural light. This is crucial for retail, art gallery, or residential lighting where color differentiation is important.
