X‑Cite XLED1 is a professional‑grade LED fluorescence light source, designed for flexible, high-intensity excitation of fluorophores in fluorescence microscopy. The system includes the illumination unit, liquid light guide, microscope adapter, four interchangeable LED modules, excitation filter holders, and optional touchscreen controller. Its modular design allows you to swap LED modules to match your fluorophore panel; rapid wavelength switching (≤ 1 ms via USB, ≤ 10 µs via TTL) supports fast live‑cell imaging and multicolor experiments. The unit delivers stable, uniform illumination without the need for frequent lamp changes, offers extensive control (USB, TTL trigger, sync out), and supports workflows from basic fluorescence to advanced time‑lapse, ratio imaging, or high-speed switching applications.

Feature	Benefit
Modular LED modules (up to 4)	Customize excitation wavelengths to your fluorophores; swap modules as research needs evolve
