Customer Reviews
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!

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.
