THINKGROW ICL SERIES
Professional Under-Canopy Energy Grid for High-Density Rooms
Effortless Supplemental Lighting
Balanced Intensity. Every Layer.
“Uniform Growth Across Every Plant.”
Eliminate shadows with the ICL Series (ICL-120|150|300) — wide‑angle lighting penetrates deep canopies for consistent flower development across the entire facility.
Lighting
Canopy Illumination
The ICL series delivers wide-angle light (up to 300°) to reach lower canopy areas that overhead lights miss.
Spectrum
Morphological Signaling
Four adjustable spectrum channels let growers fine-tune plant responses and optimize each growth stage.
Quality
Balanced Development
Light the middle and lower canopy to reduce larfy buds and support more even flower growth.
Setup
Modular Integration
Flexible mounting options with TSD stands or pipe mounts make the ICL series easy to install in any grow space.
Under-Canopy Penetration
Elite Supplemental Lighting With Maximum Coverage
“Deliver vital light energy deep into the canopy structure where it’s needed most.”
Stop starving your lower nodes. The ICL series provides wide-angle illumination that penetrates underserved areas traditional overhead fixtures miss.
-
300° Light Pattern: The ICL-300 emits light in a massive 300-degree pattern to saturate the middle and bottom of the plant.
-
Plug-and-Play Integration: Seamlessly connect to TrolMaster controllers for automated dimming and advanced light schedules.
- Shadow-Free Illumination: Eliminates the “shadow effect” from large fan leaves, ensuring every bud site receives direct photon energy for strong, uniform growth throughout the plant.
Precision Spectrum Control
Morphological Signaling For Every Growth Stage
“Manipulate plant responses with independent control over four spectrum channels.”
The ICL series goes beyond basic illumination. ICL-150 and ICL-300 models offer adjustable channels to trigger specific growth targets.
-
Full Spectrum + UV: Replicate natural sunlight or boost terpene production and plant defenses with dedicated UV output.
-
Far-Red Signaling: Use the Far-Red channel to signal the “End of Day,” accelerating the transition to flower and shortening cycles.
-
Deep Red Optimization: Enhance photosynthesis and flower density during critical stages with precise Red spectrum tuning.
Uniform Quality Logic
Balanced Development Across Every Layer
“Eliminate underdeveloped lower growth to ensure consistent, high-grade harvest quality facility-wide.”
Stop sacrificing the potential of your lower branches for top-heavy light intensity. ICL logic ensures that every node receives the energy required for uniform maturation throughout the entire plant structure, preventing the shadow effect that limits deep-canopy production.
-
High-Density Maturation: Applying light directly to the mid-section and bottom of the plant eliminates shaded, low-quality growth and promotes healthy, Grade-A formation on every branch.
-
Uniform Canopy Tracking: Maintain precise light levels deep within the plant structure to ensure consistent maturation and stable flower density from top to bottom.
-
Maximize Marketable Yield: Transforming underserved branches into premium-grade production increases your total facility output and improves the ROI of every harvest cycle.
Versatile Supplemental Precision
Solutions for Every Budget and Goal
“From budget-friendly builds to elite tech arrays—no leaf is left behind.”
The ICL series delivers modular supplemental lighting for any facility. Use the adaptable ICL-120 for budget-friendly grows, or deploy the advanced ICL-150 and ICL-300 for precise control. Every model ensures uniform plant maturation.
-
Adaptable Efficiency: The ICL-120 delivers a cost-effective path to larf-free production, supplying high-intensity full-spectrum light to lower nodes for healthy, A-grade growth.
-
Elite Tech Control: Deploy the ICL-150 or ICL-300 to unlock 4-channel spectrum control, independently tuning White, Deep Red, Far Red, and UV for precise plant signaling and even canopy development.
-
Maximize Facility ROI: By turning underdeveloped flowers into premium A-grade yield, the ICL series boosts profit margins and increases total crop value per cycle.
Remote Command Mastery
Anywhere Access, Total Precision
“Manage your entire supplemental array from the palm of your hand.”
Transition from laborer to director by managing the ICL-120, ICL-150, and ICL-300 through the TM+ Pro app. Remotely control spectrum intensity and photoperiod timing to achieve peak maturation without constant on-site adjustments.
-
Unified App Interface: Control the adaptable ICL-120 and the advanced ICL-150 and ICL-300 from one central system, streamlining facility-wide management and eliminating data silos.
-
Surgical Spectrum Tuning: Use your smartphone to independently adjust 4-channel spectrums on the advanced ICL-150 and ICL-300, triggering precise plant responses in real time.
-
24/7 Alerts & Logging: Monitor performance remotely and receive instant alerts when environmental thresholds are breached, protecting harvest quality with unlimited historical logging and zero monthly fees.
Improve light coverage, reduce larf, and maximize harvest quality.

Expert Support,
Looking for help?
Our engineers are ready to solve your most complex integration challenges. Connect with our team to troubleshoot and scale your facility.
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).
Are the ICL series lights water resistant?
Yes, they are designed for the demanding environments of grow rooms:
- ICL-120 and ICL-150 are rated IP66, featuring a sealed cover for lamp bead protection.
- ICL-300 is rated IP56.
What is the power consumption and light output for these fixtures?
All three models in the series have an input power of 120W.
- ICL-120: Up to 348 μmol/s PPF with an efficacy of 2.9 μmol/J.
- ICL-150: Up to 360 μmol/s PPF with an efficacy of 3.0 μmol/J.
- ICL-300: Up to 360 μmol/s PPF with an efficacy of 3.0 μmol/J.
Can I control the ICL series with a TrolMaster system?
Yes, the ICL series is fully compatible with TrolMaster’s Hydro-X, Tent-X, and Green-X control systems by using the LMA-T adapter
Do these lights support spectrum tuning?
The ICL-150 and ICL-300 support advanced spectrum tuning when connected to an HCS-2 or HCS-3 controller. This allows you to create custom light recipes by independently adjusting the UV, White, Deep Red, and Far Red channels.
How many ICL fixtures can I connect in a single daisy chain?
The number of fixtures you can power in a single string depends on your main power source voltage:
- 120V: 8–9 fixtures.
- 240V: 16–17 fixtures.
- 277V: 19–20 fixtures.
What are the mounting options for the ICL series?
ThinkGrow offers several flexible installation methods:
Hanging: All models can be suspended from the ceiling or above using appropriate rope or cable.
Unistrut: Fixtures can be secured directly to unistrut steel using user-provided hardware.
Vertical Stands: Specialized stands are available for vertical setups, such as the TSD-3 for the ICL-150 and the TSD-1 for the ICL-300.
What kind of warranty comes with the ICL series?
All ICL series fixtures include a 5-year standard warranty against defects in materials and workmanship from the date of purchase.
