U120C 120W Under-Canopy LED Grow Light
The U120C is a slim, full-spectrum bar intended to bring light to the lower part of a dense canopy. It is an addition to a correctly sized top light, not a substitute for one.
Choose This Fixture for the Right Job
Use it when top leaves are receiving light but lower sites remain consistently shaded. First confirm the main fixture, extraction and plant spacing are already working; then add lower-canopy lighting as a targeted improvement.

120 x 120 cm footprint
The intended working area for a single U120C in a dense, netted flowering layout.
150 x 150 cm footprint

Set Up Before You Increase Intensity
Install only after confirming secure hanging points, the product selector, cable routing and ventilation. Start with a conservative height and output setting, then adjust from plant response rather than from a generic percentage. For repeatable schedules, use a compatible plug-in timer switch and keep electrical connections dry and accessible.
Confirm the physical growing footprint, mounting height, room extraction, available circuit and any controller or cable compatibility. The product selector and current listing are the source of truth for the purchasable configuration. Check the required plug, supplied hardware and cable length before committing to a layout.
For a primary fixture, compare the LED grow lights collection before adding supplemental light below the canopy.

120W under canopy grow light FAQ
Answers to common questions about placement, compatibility, control and purchase options.
Does the U120C replace my main grow light?
No. It is designed to complement a main fixture by addressing lower-canopy shade.
Which selector option includes lamps?
Choose the 2 x lamp option when tubes and the relevant power and extension cords are required. Lamp-only and cord-only choices are replacement or expansion options.
How close should the bar sit to plants?
Mount it only after checking plant spacing and airflow. Keep it clear of foliage and adjust position if leaves react poorly.
Can one unit cover a large 150 x 150 cm canopy?
It can add light below part of a large canopy, but uniform lower-level coverage across that footprint may need more than one unit.
