LED Grow Light, 320W Grow Lights for Indoor Plants Full Spectrum Foldable, Dimmable Daisy Chain for Samsung LM281B Diodes, Seed Veg Plants Vertical Farming Commercial Grow Lights 3x3 Grow Light

For the price. I'm convinced this is the best LED grow light on Amazon. You won't regret buying it. I got her Turned to about 60% and she's hanging close to 24inches from the canopy of my veg tent and it's putting out well over 400ppfd at 60% and 24inches. Turned it all the way up just to see what it was looking like and I had a uniformed ppfd completely covering a 3×3 tent and 750-1000 ppfd at 100% still 24inches away from the canopy. This thing puts out some serious light. Would probably even work for flowering a 4×4 tent but that's about the most I'd use it for.

UPDATE::: THIS LIGHT WORKS VERY WELL IN Veg. It has given me vero issues. The plants like it and pray to it every day! I would recommend this to anyone who needs a veg light on the cheap.So from the unboxing I noticed the frame is not as high quality as others. However I did get it in on sale for $289. That being said it's decent for the money. I'm a little confused seeing there is no driver on the exterior of the light. I have heard the newer models are going to invidual driver on the lights. It is bright and not as much red as others. I can't nor verify that they are samsung led. Mine was also missing the cable used for hangingg but I had an extra so that was all good. I can't verify I'd it's actually 720 watts. But I can say it's brighter than my 650 watts. This is a 100% honest review. I'll update as I find pros and cons.

Definitely not 320 watts more like 250

The packaging is scary bad. A couple pieces of foam and a bag with hangers and a couple cables. No instructions at all. However, if you need a big powerful light this is it. Nothing even close when it comes to watts and size. I have it in a 4x4 and this light is not only super bright, but oddly runs cool. We shall see for long term, but I am more than happy for $279.

Looked great and was excited. Plug it in and nothing so go to directions nothing worked to get it powered up and the web site and customer service contact does not exist on line so I just returned the light and received another more common company lights that worked excellently the next day and put them to use.

I had a marshydro that pulls 220 from the wall and figured I'd give this one a try and wow!! I would say probably 3-4 times as bright and I have it setup in a 2x4. And everything is 2-3 times larger at my current growth stage than under the mars

I’m a bit concerned about the fact the listing changed from 720 watts to 320 watts. I’m buying a power meter to see if the originally listing was accurate. If not, I’m most certainly be returning it and filing a complaint.As for the product itself? It seems to be in perfectly fine working condition. I’ll be sure to update the review after testing the wattage.

Super output and spread/coverage, I'm convinced the bar-style lights are the best in terms of lighting uniformity.The construction is thick aluminum, light for so much metal. This thing fills up my 4x4 tent perfectly.Uniformly spread allows me to keep these at a 12" distance without leaf tip burns.The light is also very energy efficient. It uses significantly less power than traditional grow lights, which is a big plus for my electricity bill. Additionally, the light's heat dissipation system ensures that my plants don't get too hot, which is important for their health.Overall, I am super satisfied with this purchase. I doubt I will ever use another brand as BUTTERFLY FARM meets all my needs and exceeds my expectations every time.
