Ultra-Thin. Fully Addressable. Built for Creative Lighting.
The MALIIGAZA 3mm Addressable COB LED Strip combines an ultra-narrow 3mm PCB with 240 individually controllable WS2812B pixels per meter. Its continuous COB light surface delivers smooth RGB lighting with minimal visible light spots, making it ideal for compact spaces, custom installations, gaming setups, TV backlighting, PC lighting, cabinets and vehicle interior ambient lighting.
Why Choose This 3mm Addressable COB Strip?
Ultra-slim design fits narrow channels, edges, furniture gaps and compact DIY projects.
Each LED has integrated WS2812B control for single-pixel addressable RGB effects.
High-density COB construction creates a continuous and uniform illuminated surface with fewer visible light spots.
Create flowing, chasing, animated and static RGB lighting effects through a compatible SPI RGB controller.
Individually Addressable WS2812B Pixels
This is not a conventional RGB strip where the entire strip changes color together.
The integrated WS2812B architecture provides individual pixel control, allowing each LED position to display independently controlled colors and effects when used with a compatible SPI controller.
240 LEDs + 240 ICs Per Meter
Every meter contains 240 LEDs and 240 integrated control ICs. This extremely high pixel density makes the strip especially suitable for detailed lighting animations and compact decorative projects.
Ultra-Fine 3mm Design
At only 3mm wide, this addressable COB LED tape is designed for lighting locations where conventional 8mm, 10mm or 12mm LED strips are too wide.
The narrow flexible PCB can follow different shapes and allows creative lighting installations with minimal visual impact when the strip is turned off.
High-Density COB Light Surface
With 240 LEDs per meter, the COB structure produces smooth, uniform RGB illumination with greatly reduced visible light spots and dark areas compared with many traditional discrete SMD LED strips.
CRI is rated above 90, while the flexible design makes the strip practical for decorative and detail-oriented lighting applications.
Flexible, Cuttable and Easy to Install
The strip can be bent into different layouts and cut to shorter lengths at the designated cutting positions.
Strong adhesive backing allows the strip to be mounted directly onto suitable clean and smooth surfaces.
Only cut the strip at the designated cutting lines. The cutting marks are very small because the PCB is only 3mm wide. If the marks are difficult to see from the front, carefully inspect the rear side under the adhesive backing.
Smart Controller Options
Different controller configurations are available depending on the selected option.
- Bluetooth controller options available
- WiFi controller options available
- Remote control options available
- WiFi controller supports Alexa and Google Assistant voice control
- Compatible smart controller can provide app-based RGB color and dynamic effect control
Perfect for Creative Ambient Lighting
Why Maximum Length Is Limited to 2 Meters
The extremely narrow 3mm PCB combined with 240 addressable pixels per meter creates relatively high current demand.
For this reason, this model is offered in lengths up to 2 meters. Longer runs can experience voltage drop and may exceed the pixel or current capacity of many common controllers.
Your SPI controller must support at least 240 pixels for a 1m strip or 480 pixels for a 2m strip.

Basic Installation Guide
- Measure the required installation length.
- If shortening is required, cut only at the designated cutting position.
- Connect the LED strip to a compatible SPI RGB controller.
- Set the controller pixel quantity correctly: 240 pixels for 1m or 480 pixels for 2m.
- Connect the system to a suitable DC 5V power supply.
- Test the complete system before final mounting.
- Clean the installation surface and secure the strip using its adhesive backing.
Important Power and Safety Notes
- DC 5V ONLY. Never connect this strip to a 12V or 24V power supply.
- For 1m, use a DC 5V power supply rated at least 2A according to the specified product requirement.
- For 2m, use a DC 5V power supply rated at least 3A according to the specified product requirement.
- The controller and power supply must be able to provide sufficient current for the selected strip length.
- Use only an SPI RGB controller with sufficient pixel capacity.
- Do not power the LED strip while it is tightly rolled on a reel. Heat may accumulate and damage the strip.
- Cut only at designated cutting marks.
Troubleshooting Guide
Only Part of the Strip Lights Up
Check the pixel quantity configured in the controller. Set 240 pixels for a 1m strip and 480 pixels for a 2m strip.
The Strip Lights Up but Then Freezes
Insufficient power supply capacity is a likely cause. Check that the power supply can provide enough current, then reset the controller, remote or app as required.
Displayed Colors Do Not Match the Selected Colors
If selecting red produces green or another incorrect color, adjust the RGB color order setting in the compatible controller or app.

excellent product
Nice and small neo pixel strip. Comes coated in a sicone cover which acts a a difuser. There size opens up a whole wider range of applications. Neat...
These led strips get so hot that a heatpipe or a copper strip should be attached to the back of it if it's being used in free floating form.
13 coins await. Add more for up to 20 coins.

Magnificent. As described. Fast shipping. Good seller.
Very very fine and very good lighting, it's amazing.
Utterly incredible lights. You can program each individual led along the strip to be any colour, to flash, pulse, even get sequences of chasing lights in segments, having some leds of or on, perfect for lighting models or for any project. Easy to use app, very bright, very controllable, just be sure to work out which colour or action each led should be before you put it in so you don’t accidentally delete your theme. Can’t recommend it highly enough! Price is excellent and functionality is supreme!
Super tiny leds.
Good!
