Product Information
This 12V individually addressable COB LED strip light packs 240 LEDs per meter onto an ultra-slim 5mm flexible circuit board, delivering a continuous, spot-free beam across all 16.4ft (5 meters). Powered by integrated WS2812B control chips, every individual LED functions as an independent pixel, giving you 1200 addressable points per reel for fluid chasing, gradient fading, and custom animation sequences without visible dark spots.
Operating at DC 12V with 7.5W per meter (37.5W total per reel), this 5mm mini cob led light strip maintains uniform luminance and color balance from the input header to the tail when powered from one side, eliminating the harsh color fading common on 5V addressable LED tapes. For control, pair the 3-pin input with a compatible SPI LED controller.
Key Features of This 12V Addressable COB LED Strip
1200 Individually Addressable Pixels
Each diode across the 5-meter run contains a dedicated WS2812B IC driver, providing 240 addressable zones per meter for high-resolution graphics and chasing effects.
Continuous Spot-Free COB Light
Chip-on-board packaging beneath a uniform silicone phosphor matrix eliminates visible diode dots, outputting a smooth 180-degree beam directly from raw tape.
Ultra-Narrow 5mm PCB Profile
The 5mm circuit width slides directly into compact linear extrusions, narrow furniture reveals, and tight architectural grooves.
12V Uniform Single-End Power
Operating at DC 12V and 7.5W/m minimizes current load, allowing an entire 5-meter reel to hold consistent color and brightness with single-ended power injection.
Tight 12.5mm Cut Intervals
Cut points positioned every 12.5mm allow exact trimming down to the fraction of an inch to match tailored cabinet, display, and sign dimensions.
Two Environmental Formats Available
Available in 2 waterproof choices: IP20 bare board with adhesive back for dry interiors, or transparent heat shrink tube IP67 for damp and outdoor moisture areas.
Engineering Advantages & Performance Metrics
- 12V architecture draws 3.125A per 5m reel at 7.5W/m, preventing the red-shift voltage decay typical of 5V digital strips over 2m distances.
- Factory-soldered female 3-pin JST-SM connector at the input carries 12V+, GND, and DAT data lines; the output end provides dedicated 2-pin DC power injection leads.
- Compatible with FastLED, Adafruit NeoPixel, WLED, and standard commercial SPI digital decoders communicating via the 800kHz WS2812B protocol.

Recommended Installation Applications
How to Install & Wire This 12V Addressable COB LED Strip
- Inspect the LED strip for the data direction arrows (DIN to DOUT). Always feed the control signal into the female 3-pin input side.
- Measure the installation track. If trimming is necessary, cut only along the marked copper solder pads placed every 12.5mm using clean shears.
- Peel back the adhesive backing and press the tape firmly into place.
- Connect the 3-pin JST input to your SPI pixel controller, matching +12V (Red), Data (Green), and Ground (White/Black). Please note that the power cords on the output side must not come into contact with each other, as this could cause a short circuit.
- Wire a 12V DC power supply to the controller and LED strip. For multi-reel layouts beyond 5 meters, run separate DC power feeds in parallel.
