- Addressable tunable white: adjust the light from warm to cool even in sections, not just across the entire strip, for chasing effects and gradients between warm and cool white.
- From 2700 to 6500 K: from cozy evening warm white to cool white for working, with two rows of LEDs—warm and cool—on the same strip.
- COB technology, 576 LEDs per meter: LEDs are so dense that the light appears as a continuous line, with no visible dots even without a diffuser profile.
- WS2811 chip every 48 LEDs: each chip controls a group of 48 LEDs, i.e., 12 segments per meter that can be managed individually by the controller.
- Requires an SPI controller with CCT mode: not included. SPI controllers that are RGB or RGBW only do not correctly adjust warm and cool; verify CCT mode compatibility for WS2811.
- 24 V power: consumes 10 W + 10 W per meter, up to 20 W per meter with both whites at full brightness. 24 V power supply sold separately.
- 900 lumens per meter: enough light to illuminate a kitchen worktop, a ceiling cove, or the inside of a cabinet.
- Three wires: +24 V, data, and ground: three-pin connector at each end. A printed arrow indicates the signal direction: the controller connects to the DI input.
- Cut at the marked points: shorten the strip at the printed pads between groups without losing functionality of the remaining section.
- Adhesive backing: clean the surface, peel, and press. For better heat dissipation, an aluminum profile is recommended.
- IP20 or IP67 version: IP20 is for dry indoor areas; IP67 is suitable for bathrooms, under eaves, or humid environments.
- Where to use: under kitchen cabinets, in ceiling coves, on stairs, shelves, and closets, where dynamic white accompanies people passing by.

Addressable CCT COB LED strip: warm and cool white flowing in segments
The addressable COB CCT LED strip combines two things that are usually separate: adjustable warm to cool white and the segmented control of digital strips. Inside, there are 576 COB LEDs per meter , so the light comes out as a continuous line. A WS2811 chip for every 48 LEDs divides the strip into segments that the controller turns on and off one by one: the light can flow along the kitchen, up the stairs, or follow anyone walking down the hallway. It operates at 24 V , consumes 10 W + 10 W per meter, and produces 900 lumens per meter. The 5-meter reel is available in an IP20 version for indoors or an IP67 version for humid environments. An SPI controller with CCT mode and a 24 V power supply are sold separately.
Need SPI controller with CCT mode for WS2811 chip
This strip doesn't have the two wires for warm and cool white: it has three wires: +24 V, data, and ground . To control it, you need an SPI controller that sends the digital signal and has CCT mode for the WS2811 chip. RGB or RGBW-only SPI controllers turn it on, but don't handle the warm to cool transition correctly. A traditional two-channel CCT controller, designed for strips that receive power on both whites, isn't suitable either. Before purchasing, check the controller datasheet to see if CCT over SPI signal is listed among the strip types. If you don't need segmented effects, there's the 640 LED per meter COB CCT strip with a standard two-channel controller.
WS2811 every 48 LEDs: 12 segments per meter and cut at marked points
Each WS2811 chip controls a group of 48 LEDs : with 576 LEDs per meter, this creates 12 independent segments per meter. These are the points where the light can change tone or turn on sequentially. The strip is shortened at the printed pads between each group, where +24 V, data, and ground pass: cut them there and the remaining section continues to function. An arrow on the circuit board indicates the direction of the signal. The controller connects to the DI input, at the beginning of the strip, and the signal continues to the DO output. On the back, there is double-sided tape already applied, ready for installation.
Continuous COB light: 576 LEDs per meter without the dotted effect
In traditional LED strips, with spaced SMD diodes, individual points of light are visible, especially on glossy surfaces like kitchen counters. COB technology places the LEDs so close together that the light emerges as a uniform line , without dots, even without a diffuser profile. With 576 LEDs per meter, the reflection on the countertop or tiles remains clean. The COB strip is also more flexible: it follows the corners of a ceiling cove or the curved edge of a cabinet without creating darker areas. The image compares the two strips turned on under the same cabinet.
Flowing light effects in warm, neutral or cold white
The advantage of addressable segments lies in the effects. With a suitable controller, the light can flow along the strip, illuminating step by step, or following a person walking down a corridor. The effect works with cool white (6500K), neutral white (4000K), or warm white (3000K), and the brightness is continuously adjustable. Compared to a standard CCT strip, which changes tone all at once, each segment can have a different intensity. Which effects are available, and at what speed, depends on the SPI controller you choose.
Kitchens, hallways, stairs, bathrooms, and living rooms: where to use it
Dynamic white finds its place in many spaces. In the kitchen , it illuminates the countertops beneath cabinets; in the hallway and stairwell , it accompanies passersby with a flowing light. In the living room, it draws lines on the ceiling and walls; in the office, it marks paths. In the bathroom and humid areas, choose the IP67 version; the IP20 version is for dry interiors. To power the 5-meter coil with the two whites, a maximum of 100 W is required: choose a 24 V power supply with a little margin.
From 2700 to 6500 K: from warm evening white to cool white
The strip has two rows of LEDs, one warm white and one cold white, and the controller mixes them. This way, you can go from warm white 2700K , suitable for evenings and cozy spaces, to cold white 6500K , ideal for working or cooking. In between are all the intermediate tones: 3200K for the living room, 4000K for the kitchen, 5000 or 6000K for bathrooms, offices, and shops. Each tone can be combined with segment effects. If you also need colors, there's the COB IC RGBCCT strip .

Frequently Asked Questions
What controller do I need for this strip?
An SPI controller with CCT mode for the WS2811 chip. RGB or RGBW-only SPI controllers do not adjust warm and cool white properly. The controller is not included.
Is a regular two-channel CCT controller okay?
No. This strip has three wires, +24V, data and ground: the two white ones are controlled by the digital signal, not by two separate current channels.
How many segments does the strip have?
Twelve per meter. Each WS2811 chip controls a group of 48 LEDs, and the strip has 576 LEDs per meter.
Where can it be cut?
On the printed pads between each LED group. The section that remains connected to the controller continues to function.
What power supply should I use?
One at 24 V. The strip consumes 10 W + 10 W per meter: for the 5 meter reel with the two white ones at most you need 100 W, plus a little margin.
Can it be used in the bathroom?
Yes, with the IP67 version. The IP20 version is only suitable for dry interiors.
Can you see the LED dots?
No. It is a COB strip with 576 LEDs per meter: the light comes out as a continuous line even without a diffuser profile.
Which side does the controller connect to?
On the DI input side. An arrow printed on the circuit board indicates the direction of the signal, which goes from the DI input to the DO output.
