LED Ethernet Controller 3 (LEC3)
Advanced pixel LED controller built around the proprietary LED Strip Studio pixel protocol, with real-time compression that significantly reduces network traffic and enables reliable control of large-scale pixel LED installations. The LEC3 system has been successfully used to control installations with up to 200,000 individual RGB pixels.
It also supports Art-Net/sACN, DMX, and seamless integration with LED Strip Studio software. In stand-alone mode, pixel LED content can be played directly from an SD card, allowing the installation to run without a computer.

LED Strip Studio Software
Included with LEC3 is a lifetime LED Strip Studio Software license. Built specifically for pixel mapping, LSS4 makes complex LED installations easy — from drawing curved segments that match real layouts to running multi-layer video across massive displays.
LSS4 communicates with LEC3 using the proprietary LED Strip Studio pixel protocol, featuring real-time data compression that significantly reduces network traffic while maintaining reliable control of large pixel installations. This allows LEC3 and LSS4 to work together as a highly optimized system, proven in installations controlling up to 200,000 individual RGB pixels.
Built-In Protection That Resets Itself
Every SPI output is protected by a self-resetting fuse, helping prevent damage caused by short circuits or overloads. Once the problem is resolved, the output automatically returns to normal operation, reducing downtime and simplifying maintenance.
Advanced Multi-Device Synchronization
Synchronize multiple LEC3 controllers in stand-alone mode over Ethernet or DMX, keeping playback precisely aligned across the entire installation. This distributed architecture allows large-scale displays with 100,000+ pixel LEDs to run independently — without a computer — in perfect synchronized harmony.
