Technical Specs & Certifications
The WS2811B LED strip is a digitally addressable RGB LED strip that utilizes the WS2811B integrated control chip, offering precise color control and consistent performance across each LED node. While the WS2811B itself refers primarily to the driver IC, the complete LED strip assembly combines this IC with RGB light-emitting diodes on a flexible printed circuit board.
In terms of luminous efficacy, typical WS2811B LED strips produce approximately 18 to 22 lumens per watt, depending on the binning of the LEDs and the drive current used. This efficiency is standard for 5050-sized RGB LEDs commonly used in such configurations. However, it’s important to note that these strips are primarily designed for dynamic color effects and decorative lighting rather than high-lumen output or energy-efficient white light applications.
Regarding Color Rendering Index (CRI), standard WS2811B strips utilize RGB (red, green, blue) LEDs which inherently produce light through color mixing rather than broad-spectrum emission. As such, they do not have a CRI in the traditional sense when operating in full-color mode. When displaying white light by mixing RGB outputs, the resulting white is often cool and lacks spectral continuity, typically yielding an effective CRI below 70, which is significantly below the CRI >90 requirement. Therefore, the WS2811B strip is not suitable for applications requiring high color fidelity.
For applications demanding both addressability and high CRI, alternative solutions such as RGBW strips with a dedicated warm white LED (e.g., 2835 or 5050 with CRI 90+ white diodes) may be considered, though these typically use different driver ICs or configurations.
As for Ingress Protection (IP) ratings, the WS2811B LED strip is available in multiple variants depending on the level of environmental protection. Common configurations include:
IP20 – Uncoated or bare strip, suitable for indoor, dry environments with no exposure to moisture or dust.
IP65 – Silicone-coated strip offering protection against dust and low-pressure water jets. Ideal for outdoor use in covered areas or damp indoor environments.
IP67 – Fully encapsulated in a silicone sleeve, capable of temporary submersion in water up to 1 meter for 30 minutes. Suitable for harsh outdoor environments or installations exposed to moisture.
IP68 – Similar to IP67 but rated for continuous submersion under deeper water, depending on the manufacturer’s specifications.

Their programmability allows for synchronized lighting shows during holidays or events, enhancing customer engagement.
In office environments, use is more limited and should be carefully considered. While general office workspaces typically require consistent, neutral lighting, the WS2811B can be used in reception areas, conference room accents, or breakout zones to add brand-aligned color accents or support wellness-focused lighting schemes. However, it should not replace task lighting and is best reserved for decorative applications.
When installing WS2811B LED strips, proper planning and execution are essential for optimal performance and longevity. Always ensure the power supply matches the voltage and current requirements of the strip—most WS2811B strips operate at 12V or 24V DC. Calculate total power draw based on strip length and LED density to avoid overloading the power source.
Install the strip in a clean, dry environment. While some versions are available with silicone coating for moisture resistance, they are generally not suitable for outdoor or high-humidity areas unless properly protected. Use aluminum channels with diffusers to protect the strip, improve heat dissipation, and provide a smooth, even light output.
Secure the strip using its adhesive backing only on clean, dry, and smooth surfaces. For long runs or areas with vibration, mechanical fasteners or clips are recommended to prevent peeling. Avoid sharp bends—follow the minimum bend radius specified by the manufacturer to prevent damage to the PCB.
For data signal integrity, especially in long installations, consider signal amplification every 5 to 10 meters depending on data speed and controller capability. Connect the data line in the correct direction (input to controller, output to next segment) and use twisted-pair cables for data transmission when extending connections.
Finally, use a compatible controller and software platform that supports WS2811B protocol for smooth color transitions and reliable performance. Test the installation before final mounting and ensure all connections are insulated and protected from accidental contact.
