Great light, Great price
Just installed my new 320w Farmlite and have to say I'm very happy with this purchase. It covers my 4x4 tent perfectly and gives all my flowers plenty of light. Easy to put together and easy to hang. The only dislike is the amount of heat that they produce. Had to make a couple of adjustments inside the tent to compensate for the 8° temperature gain but it's nothing a fan can't take care of. Well made light at a decent price.

Great price for product
Got mine today and it wad easy to put together. They even provide the screw driver with magnetic tip. A few screws to fasten to the bars plug and play after. Good hangers and the light is excellent. The Samsung diodes are legit. Power chord could be longer but its average length for these. Easy to get a power strip and hook up for surge anyway so not a negative. Dimmer works well and you can daisy chain. Great price for product. I'll get another soon.

Great light overall
I use these lights for growing Carnivorous plants in a controlled outdoor grow building. Dimmers are set at 25% for tropical Nepenthes pitcher plants, 50% for Heliamphora & tropical pings. It could easily grow full sun Sarracenia or flytraps on 50-75% depending on height. (They’re approximately 2.5ft from our grow tables) Great light overall, we bought 3 total. It has Samsung diodes, is plenty bright & covers the grow area well. I would’ve given it 5 stars but the power cord doesn’t daisy chain. I was disappointed we couldn’t run 3 lights together on one cord. For those of us with larger plant collections & limited power outlets, this is usually a deal breaker. You can daisy chain the dim feature to one master light. Unfortunately if you accidentally hit the slave/master switch in the wrong direction, it trips breakers. So I disconnected the dimmable daisy chain cords & tune each light on separately. I’m pleased with this purchase overall & would recommend. It’s a nice light that won’t break the bank.

Great light for the money
Bought this light to use in a secondary grow tent. It performed so well that I ended up using it in my main 4×4 tent. It out performs lights twice it's price. I highly recommend it. I've checked the output with a par meter and the output is spot on.

Outstanding. IYKYK type product
I picked up this light and its bigger brother during a fantastic sale. Rather than list all the lights I've played with before, I'll just say buy this one, if budget is a concern and performance above price point is important. Running this in a 32x32. Has Even wall-to-wall coverage. Plants absolutely loved this light. It will carry you through all phases. Something in the spectrum perked them way up. Definitely a light you'll play with the dimmer with. Again, I bought two of these and I have zero regret. While this fits in the category of budget light, the performance is not budget, many of us have an incessant need to look for the best product at the lowest price, stop here. If you have a toe or more in the spectrum, all puns intended, like I do, I'll reiterate a few necessary points: Easy assembly, true dimensions as listed, fantastic value, proper length power cord, Loved it to the point I bought the bigger light as well.

Cost effective? Quality? Longevity?
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!!

Cutting corners
This light is amazing. My plants are loving it. Better find something else to adjust the height cause there's no way these hangers will fit around any pole in a grow tent. Power cord is super short, better buy an extension cord, im clueless on how you think this is acceptable. I wouldn't pay regular price for this light unless they update the hangers and power cord! How about some kind of controller to run multiple lights?
