What Is a 420W Hybrid Light With High CRI?
A 420W hybrid light with a high Color Rendering Index (CRI) is a specialized lighting fixture designed for applications where accurate color rendering is essential, such as horticulture and professional grow operations. These lights combine different spectrums to support various growth stages (hybrid) while maintaining a high CRI (typically 80+) to ensure that plants appear natural, allowing for easier health assessment. They balance energy efficiency at 420W with powerful light output, making them ideal for achieving optimal growth and yield in controlled environments.
