Prismatik is an open-source utility designed for Windows that facilitates the control of USB-driven LED backlights, primarily for Lightpack devices. This software captures screen content, analyzes the visual data, and generates corresponding ambient lighting to enhance the viewing experience. The application is particularly useful for gaming and media consumption, providing soft and gentle illumination that complements on-screen action.

In addition to Lightpack, Prismatik supports a variety of other devices including Adalight, Ardulight, and Alienware LightFX systems. As an unofficial fork, it retains the core functionalities of its predecessor while offering expanded compatibility and user-friendly controls. The software is available for free, making it an accessible option for users looking to elevate their ambient lighting setup.
