At BTF Lighting, we continuously strive to push the boundaries of addressable LED technology. Today, we are thrilled to introduce our latest breakthroughs in flexible lighting: the FCOB SPI RGBCCT IC LED Strip with WS2811 (840 LEDs/m) and the Ultra-High Density 960 LEDs/m version. Click here to check the lighting effect. 

These new products combine the smooth lighting effect of FCOB (Flexible Chip on Board) technology with the full-spectrum control of RGBCCT, offering unparalleled brightness, color accuracy, and dynamic addressable effects.

What Makes FCOB RGBCCT So Special?

Traditional LED strips have visible individual light dots. FCOB changes this by mounting numerous LED chips closely together under a continuous phosphor coating. The result? A seamless, continuous line of light with no hotspots or gaps—perfect for direct-view applications like cove lighting, signs, or architectural accents.

But these strips go further by offering RGBCCT:

• RGB gives you the full spectrum of vibrant colors.

• CCT (Correlated Color Temperature) adds tunable white light, ranging from warm white to cool white.

This means one strip can produce millions of colors and any shade of white light, from candlelight to daylight.

Head-to-Head: 840 LEDs/M vs. 960 LEDs/M

Both strips operate at DC24V and use the WS2811 addressable IC, but their density and design differ for specific use cases.

Key Similarities:

• High CRI (Ra >90): Excellent color rendering for whites and colors.

• 180° Viewing Angle: Wide, even light distribution.

• Dual White CCT: 3000K + 6000K on the same strip.

• Recommended Controller: SP530E and SP630E.

Which Strip Should You Choose?

Choose the 840 LEDs/M (10mm width) if:

• You need a slightly narrower strip for tight spaces.

• You want a balance of ultra-high density and power efficiency.

• Your project involves curved surfaces or smaller radius bends.

Choose the 960 LEDs/M (12mm width) if:

• Maximum pixel density is critical – this is one of the densest addressable strips available.

• You want the absolute smoothest, most continuous lighting effect, even at close viewing distances.

• Your application (like high-end retail displays or cinematic lighting) demands no perceivable dots.

Practical Applications & Installation Tips

Both strips shine in:

1. Architectural Cove Lighting: Seamless color and tunable white for mood lighting.

2. Entertainment & Gaming Rigs: Dense pixels for smooth animations and effects.

3. Signage & Channel Letters: Uniform light without hot spots.

4. Professional Photography/Videography: High CRI tunable white for studio use.

Installation Notes:

• Power Supply: Use a sufficient DC24V power supply (not included).

• Controller: BTF-LIGHTING SP530E, SP630E, ESP32-WLED SP803E(version 16.0) Controller.

• Solder Joints: The strip has solder joints every 0.5 meters – this is normal for flexible circuits.

• Cutting: Cut only at the designated points (every 71mm for 840LED, every 63mm for 960LED).

Final Verdict

BTF-LIGHTING’s FCOB RGBCCT WS2811 strips represent a convergence of three major lighting trends: seamless FCOB optics, versatile RGBCCT color control, and addressable pixel mapping. Whether you choose the 840LED or 960LED version, you’re getting a premium, high-density strip that eliminates the "dotted line" look of traditional addressable LEDs.

For most prosumers and installers, the 840LEDs/M offers the sweet spot of performance and value. But if you demand the absolute best in density and smoothness, the 960LEDs/M version is a world-class choice.
