Plants love the warm white light these provide, definitely an amazing purchase! The only SF4000 you'll need [;

So I just got my light in today. I am amazed at the quality of the light. Hands down quality. It has already been installed and I can not wait for my plants to bask in the light in the morning. I will update this after I have my results from this cycle. Also, the company responded to my questions super fast and got my order right out the door. I most definitely will be doing more business with them.

Very happy with the 4000s. I ordered six to see how I liked them, then ordered eight more!

My favorite light at this size!!! And his bro and sis of bigger and smaller size get down to! Would highly recommend.

Great light, great price, excellent service,fast delivery and I’m one of those hard to please types. Before you spend your money else where try SonoFarm in South Carolina. Nothing to worry about. Great Company as well.

So it was my fault the dimmer works just fine… I received an email about the switch in the back sorry about that

I got my new light, first order from sonofarm, I read the paper work, and wanted to register for the 5 year warranty, but all my emails had been deleted, tried to reach out to you for help with that, and I NEVER HEARD ANYTHING BACK! so if someone can reach out to me on that I would appreciate it. If not probably one time is all that I would purchase from you.

Seedlings seem to love it! Growing Great! Easy: hang, plug in and your ready to go. We purchased a Sonofarm because of the dimmer feature.

Just got this light looks to be well build can't wait to see what the results will be. Looks impressive!!

So far my plant loves it. This is my second Sonofarm light. Had a question about daisy chaining the 4000 with my existing 2000 so I emailed Sonofarm and Reuben responded in the affirmative in a timely fashion. Great light at a fair price. Now if only they will only heed my suggestion to ship shorter hanging cables. Depending on tent height it may be necessary to craft one's own hanging solution. Not singling out Sonofarm here as other manufacturers are guilty of the same thing. Maybe everyone should own 10' tall tents. So in conclusion 5 stars for the lights 1 for the hangers.

I wanted you to know that I loved my first light so much, that is why I came back to buy another one. I now have two tents set up and isolated in different buildings. I will now be able to produce my own seeds in one of these tents.

I will be sure to let people know about your company. Please keep making great products. I wish you overwhelming success!

This light is a great light brightness is great mean well driver is great. Customers service is A+ for a new business there doing every thing right. Im sonofarm for life. Just bought the sf4000 today. 600watts under $700 and 10x better then HLG.

I am using 4 of these over an 8 x 10 canopy. This is Compound Genetics Jokerz Candy at the end of week 2. Getting 1.76 grams per watt. Sure, environment, genetics and nutrition are huge, but these lights can process the nutes and consume the high 1400 ppm of Co2. . I’m satisfied to the point we are ordering 4 Max Pro 8s for our next run.

I love my new light! The products, shipping, packaging, and customer service from this company are all great!
The SonoFarm PRO – Farmer Series SF2000 will suit my needs perfectly!
I am using this light inside of an AC Infinity 642 GROW TENT 4X2 (48" X 24" X 72")
Thank you, Reuben!!!

Recommend product over all others in this category. Plants shown response within 2 days of using and will be purchasing another light when ready.
