U120 120W UV+IR Supplemental Grow Light
The U120 is a 120W UV and IR supplemental fixture for growers who need broader coverage than a single compact bar can provide. Its twin-bar layout is intended to be used alongside – not instead of – a high-output full-spectrum main light.
Choose This Fixture for the Right Job
Treat UV as a controlled variable. The practical approach is to fit the bar safely, begin with a limited exposure window, then adjust only after observing plant response and confirming the room is operating predictably.
Wide commercial canopy
Twin bars spread supplemental output more broadly than a single U60 bar.
OC1600-class main fixture
The listed pairing is for large, high-output canopy systems.
Late-stage schedule
Confirm this late-stage schedule plan against the listed footprint, mounting height and room conditions.
Verified canopy area
Size the fixture from the real growing footprint rather than the room name.
Why This U120 120W UV+IR Supplemental Grow Light Fits Its Role
The U120 is a 120W UV and IR supplemental fixture for growers who need broader coverage than a single compact bar can provide. Its twin-bar layout is intended to be used alongside – not instead of – a high-output full-spectrum main light.
Performance varies with plant stage, mounting height, daily light duration and the wider growing environment.

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.
This page describes the listed model rather than promising an outcome. Plant performance remains dependent on the crop, climate, watering, nutrition, canopy management and the way the fixture is installed.
For a smaller supplemental channel, compare the U60 60W UV+IR supplemental grow light.

UV grow lights for plants FAQ
Answers to common questions about placement, compatibility, control and purchase options.
Can the U120 replace a full-spectrum LED?
No. It is a UV and IR supplement, not a primary growing light.
Why choose twin bars?
The twin-bar layout is intended to distribute supplemental light across a wider canopy more evenly.
How long should UV be run?
Begin with short, gradual windows and monitor the crop. Do not assume that more exposure is automatically better.
Which main fixture does it suit?
The listed pairing is an OC1600-class canopy, though physical fit and electrical compatibility should be checked first.
Is it suitable for seedlings?
No. It is designed for controlled supplementation in an established, mature plant setup.
