SF4000 LED Grow Light, Indoor Grow Lamp for Plants, Veg to Flower Bloom, Dimmable & Daisy Chain, 4x4 5x5 Grow Tent, Full Spectrum Samsung LM301B Diodes and Meanwell Driver

Amazing value for the price. Also the best loght for a 3x3 tent that I have found. The footprint fills the space perfectly and gives great light density everywhere. The only issue I am having is that it doesn't turn on when my loght timer triggers in the morning. Im not sure if it is a user issue and I need to tweak a setting or something, and its not a huge deal as I just need to remember to turn it on when I wake up, but it does put my grow at risk if I forget, which is troubling. Again though, I will chalk this up to being my issue and not the product. It was shipped fast, packed really well, and is a high quality light, especially for the price. Also a small US based business, which I love supporting. Warranty is also amazing. At 25% power and a foot farther away, it is providing the same PPFD that my 100w light was before, and it has the juice to get fat flowers later down the road. If you're looking for a 3x3 light, this is it.

The light is awesome it works well in a 5x5 had it 4 months so far If your on a budget and want a good light with a good dimmer this is the one.its very bright and don't get very hot at all it gets a lil warm on full power nothing crazy though.it has same parts as more expensive lights like spiderfarmer

Just received my light 2 days early . Light was packaged excellent . Plenty of padding . Initial inspection it rivals the spider farmer light I bought a few months ago . Pretty much the same light with a couple differences like the heat sink thickness and diode placement . The drivers are a tiny bit bigger . But there both samsung diodes with mean well drivers which was a big deal as far as what I was looking for. After turning the light on it Bright as F. Just as bright at my other light . Very excited about it overall . Also very happy to help out a small business especially during these times . Nice hand written note from the owner making it feel like a personal purchase . So as far as I’m concerned the value of this light is incredible. Wish I had found sonofarm before I bought my SF. But hey , if I can help anyone else out and save them a few bucks so be it . I’ll do a follow up in a couple months to let you guys know the results .

First off, I’m a cheapskate. My initial statement is I am an avid “for fun” grower. Not commercial, and not a slum. I prefer to try my best at whatever I do and this hobby is no exception. With that said, I am very happy with my purchase. The company is great to work with. The lights are produced with quality. Like anything in life, more money can get you higher specs, but honestly, my pro 4,000 is doing a great job in my 5x5 thus far. You should give the American made company a chance for yourself

The price is very good, the coverage great. I want to buy American. Just got it hung and fired up. Definitely heavy duty cooling plate and runs cool. The coverage area is what sold me. Went to 12/12 and will see how she does. I have 2 new viper xs2000 beside it. Both have LM301b LEDs, been waiting to try them. Been using SMD281. BUY AMERICAN!!! SUPPORT YOUR CITIZENS. Completed grow and was happy with results. Had a 5x5 grow, corner and edge plants grew just as good so the coverage is legit. Price is a steal. It has a slight yellow tint which I wasn't sure of at first but no worries on plants. 6/25/25. Light is running right alongside a Spider farmer Evo for 2 grows and the Pro 400 is just as good. At today's prices, Soho is $ 130.00 cheaper. Buys a lot of nutes
