Versions:
xLights 2026.03, released by xLightsSequencer as the seventeenth major iteration of the open-source application, belongs to the lighting-control category and serves hobbyists, schools, churches, and professional installers who need to orchestrate large-scale LED, pixel, and conventional light shows. The package imports audio, video, and timing tracks, then generates channel-level data for thousands of DMX universes, E1.31 Ethernet, Art-Net, sACN, and serial controllers so that houses, concert stages, theme parks, and broadcast studios can synchronize color effects with music or video playback. Typical use cases include sequencing holiday rooflines, programming pixel megatrees, mapping props for television productions, and rehearsing touring stage rigs; the timeline-based editor supports layers, morphs, transitions, and built-in effects such as spirals, meteors, and curtain wipes, while a 3-D preview renders the entire layout against imported venue models to verify coverage and eliminate blind spots before deployment. Because the project stores sequences in an open XML format, users can share sequences online, collaborate across operating systems, and automate rendering through command-line tools. The 2026.03 build adds native Apple silicon support, improves H.264 export performance, and refines the model-blending engine for smoother gradients on high-density matrices. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
