## Long description

The Sirius Top-Line Energy Cluster Lights supplement set with 500 LEDs (model 50821) is an add-on lighting module intended to extend and increase the density of existing cluster light installations. Designed for use with Sirius cluster systems, the supplement set offers a contiguous run of densely spaced LEDs suitable for seasonal façade lighting, tree wrapping, window displays and indoor decorative arrangements. The module integrates with the main installation without changing the primary control hardware and provides additional illuminated length where required.
Advantages
This supplement set provides increased LED coverage and higher visual density to existing Sirius cluster light configurations while preserving compatibility with the original control system. The compact LED spacing produces an even, continuous appearance across surfaces and structures. Installation is designed to be straightforward when connected to a compatible base system, allowing targeted extension of lighting length without the need to replace the entire installation.

How to use
