It's a beast of a light .
I now have 3 of these lights. Sonofarm is an outstanding company, great service and great quality.
i needed another grow light and researched them all and found that the sonofarm was the best quality and price. this sf 4000 is very bright and well built, pretty too.i already have a mars hydro but this light is better quality and less money so you cannot beat sonofarm if you need a really good growlight and shipping was very fast , recieved it the third day after ordering/i am well pleased with sonofarm,and they are americans with great customer service,unlike the chinese people. thank you sonofarm
Have bought 4 lights from them and are planning on buying more they just look good in my gorilla tents and out preform any other light I have had in the past. They are Made in American. Had the lights in 2 days from SC to MO each time I have bought lights This company is on point with everything. Thxs SonoFarms for a outstanding product.
I did weeks of research before purchasing this light. I compared this light to lights like the gavita 650w. This light out performs the competition on many aspects and is built extremely well. I definitely will be ordering more lights from you guys! It has Samsung lm301b diodes which is a nice and efficient diode. The power draw is about 645watts from the wall. The operating temperature is reasonable for the light and also you can remove the driver and mount it outside of your grow space. Thank you for making a quality affordable product for the indoor agricultural community! I would definitely recommend this light if you a grower on a budget or even if you can spend as much as you want.
I currently own 3 sonofarm lights and they all kill the game but this new ultra X is no joke my inner node stacking is so nice and tight. Can't wait to review again and share my end result.
Hey guys, glad to be dealing with a US-based company...(maybe don’t print “Made in China” so prominently on the box.)
Can’t report on performance yet, but initially, it looks great!
Shipping/packaging was good...
On/Off switch works, dimmer doesn’t, only pretend...If you send me a replacement, I’ll give you a 5-star on Amazon...
Seems like after paying $300 plus for a light with just two switches, a customer would reasonably expect both to work when brand new.
Don’t desperately NEED a dimmer, but that would be nice...thnx.
Hands down I would recommend sonofarms grow lights to anyone trying to get big dense buds. This light is everything and more that they advertised, the par charts are exactly right and this light has slick look to it.. I'm getting a great 5x5 coverage on my flowers. And I received the light 2 days earlier than I was supposed to get it, the light was well boxed and a great pamphlet inside giving you high charts, recommended power usage , and a great overview of the company. You can't beat a 5-year warranty on a grow light. To me I got a great light and great peace of mind. Not to mention this is an American made light and the money will stay in our country. After the light has been running for a week I am further convinced that the discussion to go with Sonofarms Pro SF4000 was 100% the right choice. Thanks Sonofarm
This light is just what I wanted to fill my 5x5 the spectrum is incredible! I post quite a few videos a week with my plants and there progress and people ask me what is that and I tell them it’s the sonic farm alpha 6 and I tell them to look into buying your lights I will grow with you guys from here on out !!
I been using these lites about a year,and not only do I love there lite but also there customer service is top notch ,all my plants are healthy and happy. But I will say LEDs are alot different than hps.
This is an extremely well made light and very heavy. Awesome light
I got this light on sale for $300 and decided I had to have it to replace three cheap 100w LED units. This thing provides much better light coverage than multiple smaller lights on top of being better quality diodes. I run the same strain and this run is my first flowering with this light and my plants look absolutely amazing and the nugs are much bigger already compared to where they were this time with the last lights. Their listed PAR maps match my readings as well, so they aren't exaggerating their performance.
If you're ready to pull over a pound a run with minimal wattage, this is the light for you.
First I can't believe how quickly my order was processed and shipped!!! Thanks
Second the light is very strong and is doing a great job 👍
This is my third SF4000 and I can't recommend them enough. I'm running 2 in a 4x8 and 1 in my 4x4. Rock solid nugs for sure!!! They're fairly cheap, perform much better than my old Mars Hydro and Spider Farmer, they're US based, 5 year warranty and my girls love them. You can use discount code "darrinv8" to save an additional 5%, free shipping and no tax. I can't recommend Reuben and Sonofarm enough, seriously an amazing company with amazing lights.
So i just bought a PRO 1000 for a 2x2 tent and its working awesome, the plants are loving it! it arrived fast, the dimmer works great, and instalation was really simple. Im coming back for more thats for sure! Great light for great value!

I don’t grow your typical things with this light, I actually do citrus trees in the north. These lights are just phenomenal. Been using them for 2 years now. Just upgraded to two large lights. Will never buy anything else.
this is a great light had to buy a second light to run in my 4x4 tent.You are now my go to for lighting
This light is built well and works well. Arrived 4 days early 👍🏻
I'm currently running my 2nd SF4000 in my 4x8 and it's a tank. The ladies seriously love it. No more larfy buds lol. I previously ran Mars Hydro and Spider Farmer and this Sonofarm light blows them outta the water. I also like that they're a US based company as dealing with international companies regarding warranty issues is like pulling teeth and the 5 year warranty is huge. Give these guys a shot, I'm sure glad I did.
This is my 2nd light I haven't hung yet but I have plugged in only complaint is my coupon code would not go thur and when I asked thur chat I was totally ignored but when I said my order wouldn't go thur they replied very fast. And this was before they went on vacation and gave out code for 10%.
I now own two of these. The light output is above par compared to similar lights in the price range. My plants responded really well to the first one, so I bought another and probably will again. A great product from a small company that seems to take a lot of pride in what they do.
I been running Sonofarms quantum boards for overa year,and there great.My electric bill is way lower,and my Cannabis plants love them too.
Nice small light very bright works great in my 4x4 tent.
This Light is almost the perfect light for a beginner grower. Easy to set up out of the box, all I did was add a timer. The dimming capabilities are great and the web site has all the info in the FAQ section. The light was hung with zip ties and set to the correct height in minutes. After a couple of weeks the plants are looking like they have been outside but not stressed with heat. The 5 year warranty is a plus too!
