Hi!
I wanted to share a small project I finished a couple of years ago, .
I’ve modified 2 × IKEA LEDSJÖ LED wall lamps and added addressable RGB lighting around each lamp.
Concept
Each LEDSJÖ wall lamp consists of 5 round lights, and around each one I mounted 4 × WS2812B LEDs.
That gives:
-
4 WS2812B LEDs per light
-
5 lights per wall lamp
-
20 addressable LEDs per wall lamp
-
2 wall lamps = 40 WS2812B LEDs total
Control & electronics
Each wall lamp is driven by its own ESP8266, mounted inside the housing.
The ESPs are configured to:
-
Run the same firmware
-
Be synchronized with each other (same colors, effects, and timing)
-
Control the WS2812B LEDs via a single data line per lamp
The power supply for the WS2812B LEDs is separated from the original LEDSJÖ electronics, so the original functionality remains untouched.
Result
The result is a wall installation where both lamps:
-
Run perfectly synchronized
-
Can display animations, color transitions, and static colors
-
Create a soft RGB glow around each round light
Great as accent lighting in a gaming room, living room, or as decorative wall lighting.
Photos and a video of the final result are attached below 
Feel free to ask if you want details about wiring, code, synchronization, or power setup!
