Buyers should prioritize Luminous Efficacy (lm/W) to ensure energy efficiency, aiming for at least 100 lm/W. The Color Rendering Index (CRI) is vital for aesthetics; a CRI >80 is standard, but CRI >90 is recommended for high-end hospitality or retail. Additionally, verify the Driver Brand (e.g., MeanWell, Philips, or high-quality local brands) as the driver is the component most prone to failure. Ensure the Heat Dissipation System uses 6063 Aluminum to prolong the LED lifespan to the rated 50,000 hours.
