Selecting high-quality LED lights requires a focus on luminous efficacy (lm/W), thermal management, and driver reliability. For commercial spaces, prioritize a Color Rendering Index (CRI) of 80 or higher to ensure accurate color representation. For industrial environments like warehouses, look for IP65 or IP67 ratings to ensure dust and water resistance. Always verify the heat sink material; die-cast aluminum is superior for heat dissipation, which directly extends the LED lifespan to over 50,000 hours.
