FCOB IP66 WS2811 RGB COB LED Strip 24V 16.4ft - High Density Color

Our review of the FCOB IP66 WS2811 RGB COB LED Strip finds it best suited for hobbyists and lighting installers who need ultra-dense, uniform color chasing for interior accent and project work. The single biggest reason to buy is the Flip Chip On Board (FCOB) construction combined with addressable WS2811 ICs, which delivers an exceptionally bright, soft and even wash of color with dense LED placement and fine-grained addressability. It is not a plug-and-play kit: a separate 24V power supply and compatible controller are required, and the IP66 sleeve is splash resistant but not for long-term submersion.

Key Features

• Addressable WS2811: Built-in WS2811 ICs drive groups of LEDs to enable complex dynamic effects like rainbow, wave and snake when paired with the correct controller.
• High density 864 LED/m: Extremely dense 864 LEDs per meter combined with 24 ICs per meter provides very smooth gradients and nearly continuous light output.
• FCOB uniformity: Flip Chip On Board construction produces a brighter, softer and more even color without the dark gaps typical of traditional SMD strips.
• IP66 rainproof sleeve: A plastic outer sleeve protects the strip from splashes and dust for safer indoor/outdoor use, though it is not rated for prolonged immersion.
• Cuttable and re-attachable: Cut points every 1.64 in (41.6 mm) and 3-pin male/female connectors allow custom lengths and end-to-end linking using 3-core ribbon cables.
• Durable build: Double-layer copper PCB improves conductivity and heat dissipation for a long service life of over 65,000 hours.

Who It's For

The strip is ideal for DIY lighting enthusiasts, set builders and interior installers who want high-density, addressable RGB effects for coves, backlighting, cabinets and accent runs where a seamless color wash matters. Its flexibility, strong adhesive backing and included mounting clips make it straightforward to shape around curves and tight spaces.

It is not ideal for users seeking a complete out-of-the-box solution: a separate DC24V power supply and a compatible WS2811 controller are required, and anyone needing fully waterproof underwater lighting should look for a higher IP rating. Novice buyers should be prepared for basic wiring and waterproofing at cut points.

Pros & Cons

Pros

• Very high brightness and near-continuous light thanks to FCOB and dense LED layout.
• Addressable WS2811 ICs enable rich dynamic effects and precise color control.
• IP66 sleeve provides splash protection for indoor and sheltered outdoor uses.
• Durable double-layer PCB for better heat dissipation and long lifetime.

Cons

• Requires a separate 24V power supply and controller; not a complete kit.
• Cut ends are not waterproof and need user-applied sealing for exposed installations.

Specifications

Our Verdict

This FCOB IP66 WS2811 RGB COB LED strip is a strong value for anyone who needs a seamless, high-density color strip for accent and project lighting. Its FCOB brightness, addressability and durable PCB make it worth adding to installations where uniform color chasing matters, provided the buyer supplies a proper 24V power supply and controller and seals any cut ends for moisture protection.

Frequently Asked Questions

Does this strip include a power supply or controller?
No, the strip ships without a power supply or controller; a compatible DC24V power supply and a WS2811-capable controller are required.

Is the IP66 sleeve fully waterproof?
The IP66 sleeve is splash and dust resistant but is not intended for prolonged immersion; cut ends are not waterproof and need user sealing.

How easy is it to cut and reconnect the strip?
The strip can be cut at 1.64 in (41.6 mm) intervals and reconnected with 3-core ribbon cables and connectors, but care is needed when sealing cut portions.
