Actual plant performance depends on crop, stage, height, daily light duration, airflow and the wider growing environment.
Onboard dimming control
Start gently for young plants and increase intensity as leaf area develops.
Fanless aluminum heat management
The finned body spreads fixture heat without a light-mounted fan.
Focused placement for small canopies
The board format suits compact tents, propagation shelves and home grow layouts.
performance and placement referenceRead the 2 x 2 ft test area, not the tent dimensions
The published map measures a 60 x 60 cm area inside a 120 x 120 x 200 cm tent, at hanging heights of 30, 35 and 45 cm. The larger tent dimensions are the test enclosure, not a flowering coverage claim.
Reflective walls, plant height, dimmer position, airflow, fixture spacing and measuring equipment can change readings.
MA120 or MA200: match the light to your active canopy
Choose the compact MA120 for a focused 2 x 2 ft plan. Compare MA200 when you need a larger board; confirm flowering light levels for your crop before choosing by tent size.

Frequently asked questions
Practical answers for planning, installing and comparing MA120.
Will the MA120 suit my 2 x 2 ft tent?
The MA120 is intended for a focused 2 x 2 ft canopy, and its published map measures that area. Seedlings, herbs and leafy greens suit this compact format. For flowering, match the illuminated canopy to your crop and its light needs; the full tent footprint is not a guarantee of equal intensity.
Do I need a separate controller to dim this light?
No. Adjust brightness using the onboard dimmer. The knob changes light intensity; it is not a selectable-spectrum control. Confirm compatibility before adding an external controller or linking multiple lights.
How should I install it and choose a starting height?
Secure the fixture using the supplied hanging accessories, leave airflow around the aluminum body and keep electrical connections dry. The map shows test heights, not a universal starting setting. Start young plants at lower intensity and adjust to their response and your crop requirements.
What is included in the box?
The current package image shows the LED panel, adjustable rope hangers, steel hanging wires, a connection cable and the user manual. A grow tent and an external controller are not listed as included.
Should I choose MA120 or MA200?
Choose MA120 for a focused 2 x 2 ft plan and a compact 120W board. Compare MA200 for a larger 200W board and a wider active canopy. Check usable light across the canopy, hanging clearance and ventilation before stepping up.

You can never have enough grow lights when you have too many tropical plants and live in a place where it snows 6+ months out of the year. I saw this huge light and knew it was perfect for my monstera deliciosas. I've been using this light for the last few months and my new leaves are double the size of the ones before using the light. That it proof enough for me to know that this light is a winner!

Plants seem to be enjoying it!Also while it does get hot the heat seems to dissipate at a good rate. So its not causing any damage to the grow tent or things around it.One really nice thing i didnt expect is the vivasun controller does work with it. It can turn it one/off and adjust intensity.

Everything you see in the photo is included in the box. I needed two large carabiners to hang the light in my 2'x4' grow tent, where I overwinter my bush tomato. The light has a dimming knob and also features a port so you can link together multiple lights and dim with just one knob. The power cord is a heavy gauge and grounded, but is rather short at only ~4 feet in length.The light seems well made. It's made of aluminum and has a rather large heat sink. This light puts off a ton of heat. If I have the light at full brightness it gets to be ~95F inside my grow tent. The light is quite bright and suitable for use with established plants and with the dimmer you can dial back the brightness for your plants particular needs.
Thanks for your feedback, we have improved the power cord to 6.5 feet long, hope it helps you!

This light is a full featured grow light that was very easy to set up and install.The banks of diodes give full spectrum, and there is a rotatable knob on the top side of the light to dim/brighten as needed. While it gives a great amount of light, it isn't heavy at all. I used sticky backed hooked on the overhead joists to provide a mount.The height is easily adjustable with the pulley type attachments. In the off season when I'm not raising seedlings, this unit is easily storable- or, I'll likely raise it to the ceiling.I'm so happy, this will be a real plus as I get my garden started this year! Recommended!

I am using the TheOneGrow Dimmable LED over the Sprouting Side of our 4'X8' Grow Tent, we raise our Pepper plants & other Exotics in this area until its time to take them outdoors.I am really Happy with the Quality of the "TheOneGrow" Dimmable LED, the Plants grow Strong & Healthy with the combination of the different LED's that are used in the Grow Light. There is a Marked difference in the color of the leaves that are under the TheOneGrow Dimmable LED, they are much greener than the ones that are under our Professional 4X4 Lighting. I gave the TheOneGrow Dimmable LEDs a Full Five Star Rating Across the Board. They are easy to Setup & Use, Very Reliable, and Provides the proper light spektrum for indoor/outdoor Plants to name a few of them.
