Buyers must ensure the fixtures meet CE, RoHS, and FCC certifications to guarantee electrical safety and environmental compliance. Key technical benchmarks include a CRI (Color Rendering Index) of ≥90 for natural skin tones and a beam angle of 60° to 120° for effective audience blinding. For outdoor events, look for an IP65 rating to ensure dust and water resistance. Furthermore, check for DMX512, RDM, and Art-Net protocol compatibility to ensure seamless integration with standard lighting consoles like MA Lighting or Avolites.
