ThinkGrow 4' Inner Canopy LED (ICL), Integrated 120W driver

Light the Canopy From Inside, Not Just From Above

Overhead fixtures alone often never reach the lower canopy, leaving potential yield sitting in the shade of the plant's own upper growth. The ThinkGrow ICL-300 is an inner canopy LED bar built to work from within the plant structure instead of above it, with diodes across three sides emitting light in a 300-degree spread.

Placed inside the canopy, lower sections of the plant absorb that light directly, which can help replace weaker lower-bud formation with healthier growth, and its integrated 120W driver means there's no separate driver to mount.

Key Features & Benefits

• 300-Degree Light Coverage — reaches the lower canopy with diodes on three sides.
• Integrated 120W Driver — is built directly into the bar with no separate driver to mount.
• 314 umol/s PPF Output — delivers meaningful supplemental light to mid and lower canopy zones.
• Wide Voltage Range — operates on 100-277VAC, 50/60Hz.
• IP56 Rated — resists dust and water splashes in typical grow room conditions.

Who Should Use the ICL-300

Growers who already run overhead lighting and want to add inter-canopy or lower-canopy light, especially in larger or densely planted rooms where overhead light alone misses lower bud sites, are the intended users of the ICL-300. It's a supplement to existing overhead fixtures rather than a stand-alone lighting solution.

About ThinkGrow

ThinkGrow, TrolMaster's lighting brand, designed the ICL-300 to address a gap overhead-only lighting can't close on its own: light reaching the lower parts of a dense canopy. Its modular design fits installations of any shape or size, backed by ThinkGrow's standard 5-year warranty.

Frequently Asked Questions

Does the ICL-300 include a power cord?

No, a 7-foot splitter power cord is sold separately in 120V (TRLTDC120) or 240V (TRLTDC240) versions. Choose the version matching your circuit's voltage.

How is the ICL-300 mounted inside the canopy?

Using the included mounting hooks and adjustment knobs, optionally paired with the separate TSD-1 stand for freestanding placement. That combination lets the bar sit at whatever height reaches the lower canopy best.

What's the rated lifetime?

L90 greater than 54,000 hours under normal operating conditions. That's the point at which output is expected to drop to 90% of its original level.

What's included in the box?

One inner canopy LED bar with a built-in driver, 2 mounting hooks, and 2 adjustment knobs. Power cord and stand are sold separately.

Can I mount multiple ICL-300 units together?

Yes, the modular design and optional TSD-1 stand support daisy-chaining multiple units. That lets a larger canopy get inner-canopy coverage from more than one bar.

What temperature range does it operate in?

32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). That range covers typical indoor grow room conditions.
