When sourcing LED cabinet lighting, you must prioritize Color Rendering Index (CRI); a CRI >90 is essential for retail or high-end displays to ensure colors appear vibrant and true. Additionally, evaluate the Color Temperature (CCT), typically ranging from 3000K (Warm White) for jewelry to 6000K (Cool White) for electronics. Ensure the Luminous Efficacy is at least 80-100 lm/W to balance brightness with energy efficiency, and verify that the Heat Dissipation System uses high-grade aluminum profiles to prevent LED burnout and extend the lifespan to over 50,000 hours.
