ThinkGrow 4' Inner Canopy LED Bar (ICL-300)
The ThinkGrow 4' Inner Canopy LED Bar (ICL-300) is a specialized 120W supplemental horticultural LED light designed to bring additional light deep into the middle and lower sections of dense plant canopies. Unlike traditional overhead grow lights, the ICL-300 features a unique three-sided LED design with 300° light coverage, helping illuminate areas that may receive insufficient light from fixtures positioned above the canopy.
Its compact 4-foot format, built-in driver, four adjustable spectrum channels, and integration with TrolMaster control systems make the ICL-300 an advanced solution for commercial indoor growing environments and high-density cultivation.
300° Inner-Canopy Light Coverage
The ICL-300 is specifically designed for inner-canopy lighting. Its three-sided LED surface distributes light across a 300° pattern, allowing photons to reach the middle and lower portions of the plant structure where overhead lighting may be blocked by upper leaves.
By supplementing light inside the canopy, growers can improve overall light distribution and create a more consistent lighting environment throughout the plant.
4 Adjustable Spectrum Channels
The ThinkGrow ICL-300 provides four adjustable spectrum channels for advanced lighting control:
- White / Full Spectrum
- Deep Red
- Far Red
- UV
These independently adjustable channels give growers greater flexibility to tailor supplemental lighting according to different cultivation stages and lighting strategies.
When paired with a compatible TrolMaster HCS-2 or HCS-3 controller, the four spectrum channels can be independently adjusted to create customized lighting recipes.
120W Supplemental LED Performance
The ICL-300 combines a compact design with efficient supplemental light output.
Key performance specifications include:
-
Input power of 120 W
-
PPF greater than 314 µmol/s
-
Autosensing 100–277 V, 50/60 Hz input
-
Operating temperature of 32–104°F / 0–40°C
-
Operating humidity of ≤90%
Its integrated 120W driver helps simplify installation by eliminating the need for a separate external power supply.
4-Foot Three-Sided Design
The ICL-300 uses a compact 4 ft / approximately 1.2 m format designed for placement directly within the crop.
Its three-sided LED construction distributes light in multiple directions instead of concentrating output in a single downward-facing beam. This makes the fixture particularly useful for dense cultivation layouts where conventional top lighting may not adequately reach lower sections of the canopy.
TrolMaster Compatibility
The ThinkGrow ICL-300 is compatible with TrolMaster lighting control systems, allowing growers to integrate supplemental inner-canopy lighting with centralized environmental and lighting management.
Compatible systems include:
You can connect the ICL series to compatible TrolMaster systems using the LMA-T Lighting Control Adapter.
For advanced independent control of the ICL-300's four spectrum channels, ThinkGrow specifies the HCS-2 or HCS-3 controllers.
Up to 256 Fixtures per LMA-T
The ICL-300 is designed for scalable commercial installations. A compatible TrolMaster LMA-T adapter can support up to 256 ICL fixtures, allowing multiple supplemental lights to be incorporated into a centralized lighting network.
This makes it easier to expand an inner-canopy lighting system as the cultivation facility grows.
Daisy-Chain Power Capability
Multiple ICL fixtures can be connected within a power chain, with the maximum number depending on the facility's supply voltage.
ThinkGrow lists approximately:
-
120 V: 8–9 fixtures
-
240 V: 16–17 fixtures
-
277 V: 19–20 fixtures
This scalable power architecture can help simplify wiring in larger commercial installations.
Flexible Installation Options
The ICL-300's modular design lets you adapt it to different cultivation layouts.
Installation options include suspension, mounting to structural supports, or vertical positioning using the compatible ThinkGrow TSD-1 LED Stand for ICL-300.
This flexibility lets you position the fixture where supplemental light is most needed inside the canopy.
IP56 Protection
The ICL-300 has an IP56 protection rating, protecting against dust intrusion and powerful water jets.
This makes the fixture suitable for the humid, demanding conditions commonly found in professional indoor cultivation facilities.
