ThinkGrow Model One ICL-300 LED Bar – Inner Canopy Supplemental Lighting

ThinkGrow Model One ICL-300 Inner Canopy LED Bar – 120 W Driver Built In

Versatility in one bar — use it as under-lighting or inter-lighting — you choose. The ThinkGrow ICL-300 is a 4 ft inner-canopy LED bar engineered to transform light penetration in dense plant structures. By emitting light in a 300-degree pattern, the ICL-300 delivers energy to lower and inner leaves that would otherwise be shaded, improving yield quality and overall plant health.

Traditional top lighting leaves the mid and lower canopy starved of light intensity, often leading to weaker growth and smaller flowers. The ICL-300 solves that by bringing full-spectrum illumination into the middle of the plant canopy, producing stronger secondary sites and more uniform development from top to bottom.

Important Note: The ICL-300 LED will not function properly with the Hydro X Station (HCS-1) controller. The ICL-300 is a four-channel fixture, while the HCS-1 supports only two channels. For full functionality, use a compatible ThinkGrow controller like the Tent-X

The ICL-300’s modular design allows it to fit any grow space configuration, making it ideal for high-density indoor operations or commercial vertical farms. Whether used beneath the canopy or between plant rows, it provides consistent supplemental light exactly where plants need it most.

*Power cord and stands are sold separately.
