      FAQ

      What is the primary purpose of the ICL series?

      Traditional overhead lighting often fails to reach the lower sections of plants, leaving leaves beneath the canopy with insufficient light. The ICL series addresses this by providing supplemental light to the middle and bottom of the plant structure, which helps eliminate lower-quality flower formation and replaces it with healthy blooms, ultimately increasing overall yield and quality.

      What are the main differences between the ICL-120, ICL-150, and ICL-300?

      The primary differences lie in their beam angles and spectrum capabilities:

      • ICL-120: An under-canopy bar with a 120-degree light pattern and a single full-spectrum channel.
      • ICL-150: A multi-purpose bar with a wider 150-degree beam angle. It is compatible as a top, side, or under-canopy light and features four spectrum channels (Full Spectrum, Deep Red, Far Red, and UV).
      • ICL-300: An inner-canopy bar with a 300-degree light pattern for maximum coverage within the plant structure and features four spectrum channels (Full Spectrum, Deep Red, Far Red, and UV).
