Smart Studio Lights are Expensive... So I 3D printed mine!

💡Want professional lighting for your desk or videos without spending a fortune? In this project, I built a slim, customizable RGB key light using an ESP32-C3, WS2812B addressable LEDs, and a 3D-printed case—all for a fraction of the price of commercial options like the Neewer, Godox or Elgato Key Light.

This light is fully controllable via WLED and integrated into Home Assistant, making it perfect for automations or just quick control from your phone. Whether you're a maker, content creator, or just love building smart gear, this project is easy, affordable, and fun to customize.
