Description
Light the Lower Canopy, Not Just the Top
The ThinkGrow ICL-300 Inner Canopy LED Bar is a 120W four-spectrum LED bar that sits inside the crop rather than above it. Diodes on three sides throw light in a 300-degree pattern, reaching the lower and inner leaves that top lighting leaves in shade. Its driver is built in, it puts out more than 314 µmol/s (about 2.6 µmol/J), and its IP56 housing copes with the humidity deep in a dense canopy.
Key Benefits
- Light where top lights cannot reach - 300-degree output feeds the mid and lower canopy directly
- Four spectrum channels - white full spectrum, deep red, far red and UV, each adjustable from a TrolMaster controller
- Built-in 120W driver - no separate driver box to mount
- Moisture resistant - IP56, rated for up to 90% humidity and 0-40 °C
- Long life - L90 above 54,000 hours, with a 5-year manufacturer warranty
Why Do Lower Leaves Underperform Under Top Lighting?
Light from overhead fixtures falls away quickly through a dense canopy, so the lower and inner parts of each plant get a fraction of the intensity at the top. Those shaded leaves contribute little, and the growth they support stays weak and uneven. Adding light inside the canopy evens out intensity from top to bottom, so more of each plant works for you without pushing the top lights harder and adding heat.
How to Use
- Position it inside the canopy - hang it, or stand it on two ThinkGrow TSD-1 stands (sold separately), between rows of plants.
- Power it - it connects to the mains through a ThinkGrow Model One UK power cord (TDC-240u), which is not included and must be bought separately; further Model One fixtures daisy-chain from it with Model One daisy-chain cords, up to 16 ICL-300s on one 230V circuit.
- Connect a TrolMaster controller - a Tent-X or a four-channel Hydro-X system - to set each spectrum channel and its schedule; without one, the far-red diodes stay off.

Frequently Asked Questions
Do I need a controller?
It lights without one, but the far-red diodes stay off and you cannot set the four channels separately. A TrolMaster Tent-X or a four-channel Hydro-X system unlocks full control; the original Hydro-X HCS-1 handles only two channels.
How do I mount it inside the canopy?
Hang it between rows, or stand it on a pair of ThinkGrow TSD-1 stands, which set the height and make daisy-chaining a row of bars easier.
Is a power cord included?
No. To run it you need a ThinkGrow Model One UK power cord (TDC-240u), which is not included and is bought separately. Further ICL-300s or Model One fixtures then daisy-chain from it with Model One daisy-chain cords.
