Product Information
Unlock complete design freedom with our Super Flexible LED strip. Engineered with a unique S-shaped, serpentine PCB, this strip bends and contorts to create tight turns and custom curves effortlessly. It's the ultimate solution for projects that standard, rigid strips can't handle, such as intricate channel letter lights, complex logos, and curved architectural accents.
The slim 6mm profile fits into the narrowest of spaces, while the high-density 2835 SMD LEDs deliver smooth, consistent illumination. Available in nine stunning single colors and both 12V and 24V DC options, this strip provides professional-grade lighting for detailed and demanding applications. For higher brightness, a 6mm 120LEDs/m S version is also available. We also offer similar models, including the 5mm 60-LED, 5mm 72-LED, and 8mm 60-LED cobra strips. Please select the strip width and brightness based on your specific needs.

Key Features
Unique S-Shape PCB Design
The innovative serpentine circuit allows the strip to bend laterally, making it easy to form tight curves and complex shapes without damaging the components.
Ultra-Slim 6mm Profile
Its narrow width is perfect for installation in slim channel letters, tight corners, and compact backlighting applications where space is limited.
Wide Range of Color & Voltage Options
Choose from nine vibrant single colors and multiple white temperatures, available in both 12VDC and 24VDC to match your project's specific requirements.
Precision & Versatility
The strip can be cut every 3 or 6 LEDs for custom lengths, and its strong 3M adhesive backing allows for simple and secure peel-and-stick installation.
Technical Highlights
- Specifically engineered for fabricating channel letters and custom signage.
- Epistar 2835 SMD chips ensure reliability and consistent light output.
- Fully dimmable to create the perfect ambiance for any setting. See compatible LED dimmers
- Low voltage operation (12V/24V) for safe and easy handling.

Application Scenarios
How to Install & Use This LED Strip
- Ensure the installation surface is clean, dry, and free of dust or oils.
- Measure the required length and carefully cut the strip along the designated copper cut marks.
- Connect the strip to a compatible 12V or 24V DC power supply. For dimming, connect a single-color LED dimmer between the power supply and the strip.
- Peel the protective layer off the 3M adhesive backing and firmly press the strip onto the surface, shaping it as needed.
- Power on the strip to test the connection and enjoy your custom lighting installation.
How To Wire Single Color LED Strip Lights?
1) LED strip lights directly connect to the led power supply:

2) Multiple led strips are conneted to the switching power supply:

3) Dimming 2 pin single color led light strips:
- Always use the correct voltage (12V or 24V DC). Connecting to the wrong voltage will permanently damage the strip.
- This is an IP20 non-waterproof strip. It is intended for indoor, dry environments only.
- For runs longer than 16.4ft (5m), power may need to be injected from both ends to avoid voltage drop and ensure consistent brightness.
Frequently Asked Questions
Q: What makes this 'S-Shape' strip different from a regular LED strip?
A:Its unique serpentine (S-shaped) PCB allows it to bend and curve sideways to follow complex shapes, a feat impossible for standard strips which can only bend on one axis.
Q: What is the main application for this type of flexible strip?
A:It is specifically designed for creating custom LED signs and channel letters, where illuminating tight curves and intricate fonts is essential.
Q: Can I use this LED strip outdoors?
A:No, this is an IP20 rated strip and is not protected against moisture. It should only be used in dry, indoor locations.
Q: How do I choose between the 12V and 24V versions?
A:The 24V version is generally recommended for longer continuous runs as it experiences less voltage drop, resulting in more consistent brightness from end to end.
