Philips RGBIC Floor Lamp WLED Mod

Overview

This project describes how to convert a Philips RGBIC Ambient Floor Lamp into a fully controllable WLED device using an ESP32-C3 or an S3 for Sound Reactive. The original controller inside the lamp is replaceable to control the LED strip with WLED direct. The lamp can be purchased @Action here is the Link: https://www.action.com/de-de/p/3219917/philips-stehlampe/

Price is : ~14€ – 19€ depending on availability, i bought two units 2025 during the Christmas season for experimentation.

Motivation

Remove remote(i hate searching it) & vendor lock-in
Gain full control over the LED strip
Integrate into Home Assistant / local network
Use WLED effects and automation
Optional: sound reactive lighting

Cost Estimate

Approximate cost for modification:

ESP32-C3 Mini: ~2$ (with out sound reactive) / in the end it was an ESP32-S3 Mini (with sound reactive) ˜7$
Step-Down Converter: ~1$
Microphone (optional): ~2$
Resistors, wiring: maybe 2/3$ whatever was available in AFRA

Total: ~17/25$ Most components are easily available.

Time:

- Version 0.2 ˜relaxed 3.5 hrs.

- Version 0.1 maybe ˜6 (rebuilds and searching the parts)

Hardware

Required:

ESP32-C3

Step-Down Converter (MP1584)
330–470Ω resistor (data line)

Optional:

INMP441 microphone
BC558C transistor
Electrolytic Capacitors: 470uF 10V && 470uF 16V
Capacitors: 220Ω / 330Ω / 470Ω / 4.7kΩ / 110kΩ

LED Internals

Inside the lamp:

Red → 12V
Black → GND
Yellow → Data

LED strip:

WS281x compatible (likely WS2811 segmented)
38 addressable units

Power Setup

* check Step-Down by voltmeter

* Step-Down need to have an output of exactly 5V (+/-0.2V) before connecting the ESP
