Flickering Issues: Flickering happens when the LED driver cannot provide a stable current and result in eyes strain and discomfort especially in spaces where people spend long hours .
Overheating Problems: Poor-quality COB downlights lack proper heat management systems. This causes LEDs to overheat, leading to reduced lifespan and decreased light output and efficiency.
Low Color Rendering Index (CRI): Cheap COB downlights often have a lower CRI, leading to inaccurate colors. This is problematic where true color representation is essential.
Inconsistent Light Output: Low-grade lenses lead to uneven light distribution, multiple scallops and poor visual comfort.
Short Lifespan and Frequent Failures: Poor build quality and weak drivers causes COB downlights to fail prematurely.
