1. Precise wavelength: 365nm/395nm mainstream options, single wavelength without clutter for optimal fluorescence excitation;
2. Qualified UV irradiance: ≥300μW/cm² for short distance (1-3m), ≥500μW/cm² for long distance (3-8m), no dark areas in fluorescence display;
Uniform light spot: 45/60° wide-angle lenses recommended, no fault, soft light to avoid local high intensity;
3. No visible light leakage: No purple light in near-UV, no interference with other lights,  4. prevent light pollution;
5. Dimming & control: 0-100% stepless dimming, DMX512 console compatible, remote control optional for commercial models;
6.Scenario adaption: Compact & easy to install, linkable with color wash lights, perfect for wedding/commercial show fluorescence themes.
