Two years of continuous 12/12 cycle with zero issues. Get a small fan for the driver. It gets hot.
Size: 320watts
Im super pleased thus far and would definitely buy this again. Its been on a 12/12. on/off cycle constantly for the past 24 months and still running strong. No burnt out leds and zero issues. I'd recommend a small fan to blow directly on the central driver. It will get overly hot without it. The size is perfect for a 4x4 grow tent. I got the 320watt with six bars. I chose that style so I could swap bars if anything ever burned out. Its decently heavy so use good hangers. No build in timer but I have a plug mounted one. I supplemented this with farmlite 120watt string leds and I get GREAT results. I've been able to finish 12 plants at once in my set up. Ill keep buying farmlite. I've purchased a 4 farmlite units and every single one is still going strong. Other "cheap" light always broke in a year. This is the one to go with.

Tomatoes growing beautifully under this.
Size: 320watts
This grow light is very good. I currently have 3 cherry tomato plants that are over 9 feet tall with this light. I also have a few Romas. Its very easy to use and I plug it right into my smart plug which gives me great functionality with timer. This grow light has a large reach I even used it to extend the life of other plants like Herbs, brocolli and my succulents are doing well. I sat some of them a little distance away from the light even and it reaches it fine. The light is durable do note it is bright. Im very happy with my purchase so far especially as I tried other lights that just didnt cut it. When comparing prices this one wins every time for me.

Real Talk, read below for faith 🙏
Size: 320watts
Got this light lil less then a year ago and started my grow adventures. I will say when I 1st turned it on it felt like that video of the dude turning on that extremely big light bulb that makes the whole block glow like the sun. Anyway when I started off the grow it went not to well but I have made big strides in time. While I have used this 320 watt version exclusively the only thing I would say bad about it is the heat from the drivers can cause the tent to raise in temp depending on your (set up) / (location) easy fix tho.. the next con is the way it hangs with the included wires. What I mean by that is it leaves about a foot of room at the top of the light from your tent roof if your hanging it from the poles. But again easy fix if you have spare rope or hanging devices around or hang it in a way that works better then intended. I will include pictures of what I mean... The light is at max height with ratchet straps attached to the included wire hangers... In conclusion for the price I got this light at which I think was like 15% off from the current price, I'm very happy and satisfied with the results. Dimming knob works from 0%-70% after that the difference you can see is so slight from 70-100% it is there but it's basically at max at that point. So just pump and dump 🫡 IMO.... But you do u bb Can be tricky to hang alone, would recommend asking for help or thinking 🤔 well before doing... Maybe YouTube it 👀 save yourself headache, I did I ran it 18-6 and 12-12 light schedule, energy bill didn't move much... If it ever stops working or gives me problems I will be back with updates @kazz_sleeps if you want to see the progress 💜 4/5 star cause they could improve on it, but I would still buy another to chain them together!

320 Watts. Great lights as far as brightness and they don't get too warm.
Size: 320watts
Definitely good lights and the price is very fair. I haven't had them for more than a couple of days but if they last long this brand will definitely be my goto. In the picture the brightness is only at 75% and I am very pleased. Customer service even contacted me through email to inform that if I have any issues to contact them and even asked me if I would need a longer cord and to just contact them if I do. Getting off to a great start. If you're looking for more lights, I've been looking g for a while now and haven't found anything better than these for the price and brightness, especially for Cannabis. They even have UV chips and I like how they're spread out. You will not find many lights with UV at this size and quality. Will update if anything changes.

Cost effective? Quality? Longevity?
Size: 320watts
I purchased the 320w for my 4x4 tent. It is a perfect size with a large par footprint. In fact it covers the floor from edge to edge. The plants really took off once I replaced old lights to the farmlite. The quality seems good with only issue is not all the screw holes were tapped so would not accept the screw. After several weeks of using this light it went on sale for Black Friday. I purchased a 2nd 320w for my 2nd tent. This allowed me to free up old lights to use for other projects. Once again some holes were not tapped. Packing was satisfactory with no box or content damage. I'm my opinion this is a very good value for $189.99 and even better for $151.99 on black Friday. I have been using one for 5 weeks at 75%, for 16 hours a day since my plants were already fairly well established. I just switched to 12/12 for flowering. The growth surge is comparable to the growth surge of a 600w hps light flipped to flower. I could see the difference in 48 hours. I'm thinking it may out preform the hos light. Right now I say it's a cost effective and quality light. I can't yet judge longivity but if I get close to the 50,000 hours life span my opinion will be 10 stars. If it fails at less then 25,000 hours my opinion will be 0 stars. Check back in 6 months for updated. UPDATE: I have used this light for 1 year now and it's my flower light. It produces top quality, large dense buds. I love both of mine!!

Compatible with ac infinity and Vivosun grow hubs
Size: 320watts
I got these lights a year and a half ago and it’s still going strong!! Full Spectrum lights that my plants LOVED!!! They grew so big and strong, nice dense and huge buds!! Able to connect multiple lights together if needed. Light brightness is assistance. These lights even work with my Vivosun Grow hub and I can control everything from the app, when the lights turn on and when to turn off, adjust the brightness level. I love these lights!
