BESTVA Pro-4000W Quantum LED Grow Light 6x6.5 ft Flower Compatible with Samsung LM301B Diodes & MeanWell Driver Dimmable Grow Lights Full Spectrum for Indoor Hydroponic Plants Veg Bloom 992pcs LEDs

I just received the quantum pro 4000 and honestly, so far so good. I had my plants under 1 regular 1200 and 1 of the 1200 cobs and changed to just this one about 3 days ago. My plants in veg were doing great, put in this new quantum board, now they are doing even better now. Actually perked up even more, the green really came out in the leaves so I’m happy for now. Will write another review after harvest and we will see if the stars go up or down.

It's 5 stars but I am not sure how they wanted to to rate warmth and thickness with stars, makes no sense. It doesn't get super hot but does produce heat. It's very thin but so are all QB's.

There’s nothing else to say that hasn’t already glorified this like...Get it and be satisfied with the results this thing can produce given the right environment, nutrients and attentive growing...

This was packaged great. Light is very well constructed, comes with all you need to plug in and go. The dimmer switch is a great feature. I highly recommend this light.

shot out to rick, so professional !! The light is Bright , lite and the price is right!!!... buy it you will not regret it.. great communication in regards to the delivery, very professional... nothing but good things to say!!!

As described. Good product

It has taken more chunks out of my head than playing football wear sunglasses and a helmet that is all thank you

Wow! I have no idea what I was missing until now. My tomatoes will love these lights! Haven't had longer than 2 weeks, so I can't speak to longevity, but so far, I'm very impressed.

My girls love this light don’t think about it just buy it. You will thank yourself later.

Works well

My plants love this light. They have really exploded since I put this light over them. I am saving up to buy a second one!!

Very nice light covers a 5’x5’x8’ nicely. I recommend keeping a larger fan braced properly above the light to cool the drivers. Overall great light quality.

Amazing service and product, extremely easy setup. Hanging was easy and was basically a plug and play. Quality product from the LED's to the frame work of the light. Looking forward to ordering another in the future.

Killing it with this light and the pro-2000 in a 5x5 tent.. wont be disappointed with this light. must buy

Definitely will be using this brand from now on...

After using multiple different products these lights seem to be the best. They are a great price (value) for the product and work great. I’m happy to have found this company and the customer service has also been quick, responsive and friendly. Will be buying more in the future.

It looks good but i thought it was supposed to have a water proof coating i ordered 2 and mine doesnt seem to have anything coating the diodes

This is a powerful life well worth the money I would expect any grower that needs a light to buy this light give it a try you won't be sorry amazing results

I have the power of the sun in my grow room!

It's a good product but costly

As described

For the price and the quality well worth it

Love how simple this is and you’ll love the bright as f**k light omg

So far I love this light I had it for two weeks I don’t use the dimming option full blast all the time . I will definitely be ordering some more I would like to have two more

It’s def runs hot beware get a good intake fan but def see a difference in 2 weeks of quality and strength of light compared to the burlpe lights

I am seeing phenomenal results in a short period of time. I had a crop a week out from harvest. I put that light on it and sea results in that time frame. AMAZING.

This light is incredibly bright! Sunglasses are a must. I just started flowering with it so too early to tell but I expect BIG results.

Best light in this price range. Super bright, though best suited for a 4x4 and not a 5x5. Still one of the best lights on the market. No doubt about that.

These lights are amazing! Making the switch from HPS and metal halide never felt better at this price point. Arrived promptly and undamaged! Will definitely be buying more of these! Thanks bestva!

Damn good lights, super bright, plants growing quite well. Looking forward to getting many more in the future as my operations expand.

Saw a big difference in buds and color..want to thank Stella and the good people at bestva

Love this product! I have been using this product for about 4 months now, I have got one harvest out of it, and it crushed it! Guaranteed awesome product. Highly Recommended!

These are awesome lights, super bright great size foot print, no complaints!

This is a great light now for what I paid I this this is starting to creep out of the budget lights I guess for what this covers in flower you can’t beat the price but the light is rocking it

The dimming function is not so great. It works well, you just have to unscrew the driver and turn them over to adjust brightness. Also, there is no indicator letting you know how bright you have it set. Other than that the light works exceptionally well, and seems to be quality built.

My plants responded to this light within the first 2 days, flower has increased already. Very bright.

The light so far has been doing pretty decent . Although I recommend moving your light left to right for a more even coverage. As you can see the middle getting the best penetration.

Ive bougt them all and bestva is nice! Salty in price but worth it.its lighter than most and cooler as well and also gives options on power shut off were others do not and adjusting watts is a dial !better than maxi sun.they are hot and heavy!i will buy more bestva.

So efficient yet powerful at the same time. If using during the warmer months, a temperature-regulating in-take fan would suffice. Can run four of these lights on one outlet. Impressive ! Hopefully they’ll be more affordable later down the road.

These lights are extraordinary. At a third the price of next light you can’t beat it. I have 2 of the 4000 module worth every dime.

Very bright, and puts off quite alot of heat aswell. Be careful with this light, I burned some autos my first day. Now I keep the light at least 3 ft above the canopy. Overall very pleased with my purchase.

It puts out some heat, but my girls love it. Using it in a 4x4 setup and it covers the area.

I made 75 dollars off this light and the person I sold it to wants another one he's very happy with it.cha ching for me

Bought two pro-4000 was the best choice for the money and quality. And customer service was amazing . Looking to do business with them in the future.

This is far the best led light I’ve bought! I would recommend this for all growers from beginner to professionals.

This light is awesome it is very bright and powerful..gives off very little heat.. think it's a little expensive there are other lights out there now with the same technology.... it has A good warranty... If it lasts the 10 or 11 years they say than it's worth it.....

The pro 4000 is a great light I have a 10x10 tent and 4 of the bestva LED lights and it’s working out great. They have a dimmer and daisy chain function that is very useful I’m vegging in 30% power. They run cool and are light weight. The company is very helpful I will be buying more when I get more space .

Awesome for indoor growing

Man this light is bright. Running it in a 3.6 x 3.6 tent and it is like the sun. Light it self stays cool but the drivers put off a good amount of heat when at 100%. I added a fan blowing directly on the driver and it seems to be running much cooler now. Make sure you have plenty of airflow. Can't wait to get my first harvest.

Awesome! budget fan-less Quantum board LED light. I have four that I have been running over a year with no problem. results are fantastic .

I spent months comparing specs on many LEDs. I bought the pro 14000 hours after learning about the model. This light offers high performance at a approachable price. My first round was so good, I bought a second one. If you are thinking about making the switch this is the light to buy.

Awesome light supposed to replace 1000 watt HPS and it looks like it will do that and more with a fraction of heat and electricity!!! I had the SpiderFarmer 1000 and it produced a nicely after seeing it outperform my other LEDS of about the same cost with a clean light that’s not purple Cables are a little thin feel like it could break if it weighed much more but I would and probably will buy another WhiteDog

Real led grow light for the real growers big big big difference keep up the good work super bright any video that you see on these leds don't do it justice

Incredible light!!! This blows my “blurple” lights out of the universe!!!

Upgraded to a 5x5 grow tent and needed something to pair with my 2x4 led and im glad i went with the pro 4000. My plants are loving it just as much as I am. Easy to use, bright as can be and have improved the overalls plant quality 10 fold.

Light works great but after only 3 months, I had a driver go out on it so only half the light works now. I reached out to customer service and did some basic trouble shooting, after it didn’t work they promptly mailed me a new driver. I would definitely do business with them again.

Good light but won’t replace 1000 watt hps there is very big Different this light can replace 300 watt hps also noticed the growth is slowly For the medical tomatoes lol in veg cycle is

GREAT light! Sure bright. Doesn't get too hot at all. I'm ordering another.

You will not be dissatisfied trust me! Pull the trigger and vent amazed at what these can do. Very happy with the light spectrum!

These things are soooo bright. They hang really well in the tent. Light for the size and run silently. As long as the longevity of these last, i cant imagine having any complaints.

These lights are super strong for the price! Loving them already.

Excellent value for dollar. Probably one of the best plug and play lights you'll find at this price point, unless you're willing to wait for the slow boat from china.

This light is fantastic go ahead spend 900.00 to 1000.00 you will get a good light but you don't have to spend that much to get a better light and better company to stand behind it I've been through lots of lights not being a cheapskate but a wise spender and I''m telling you for the grower wanting an excellent outcome this is it, as is their whole line My 4000 is super and my next [purchase when affordable will be a 1000 .

This light is the absolute best!! Seriously everything about it is on point! The customer service is even better!! I ordered my light 3 days before the new ones with dimmers came out and they gave me two of the best possible solutions. Stella from customer service solve that issue is less than 24 hours. I am 1000% happy with my purchase, and will be a repeating customer!

Whats not to like, best grow lights available for a personal set up..probably even for commercial ... lights are very well engineered and built...for the cost nothing even comes close...these are the only led grow lights id recommend to someone.

The best light for the price and for Yeild and the time is much faster from seed to harvest

This light is an absolute beast. You need sun glasses to work in the tent. The power draw off the wall isn’t terrible either. I’m just under a 450 watt draw. I’m adding another tent. This will likely be the light that goes in there as well.

Love the light, plants love the light. First cannabis run was 1.55grams per watt. Yieled over a pound of some dank!

Love the light. I've had it for a few months now. it does get hot but I put a small fan over it to keep it cooler. The results of this light are great. I also have a Mars Hydro epistar 320. Both are good lights but bestva seems a little better and not as heavy.

Bright AF! Runs a bit hot as it does not have heatsinks. Inconvenient to adjust power. Plants love it! Allow some room between canopy. It's intense. A bit over priced for an import. I don't regret purchase. However, there are better options out there.

Great lights. They didn't disappoint. High quality and plants seen to love. No noticeable loss in weight but huge difference in electric bill and cooling costs. I switched from double ended 1000 watt hid to these and wish I had dinner sooner.

Can say enough about this light!!! Super bright, quality build, doesn't get to warm have a small clip on fan blowing on it...Got it in a 5×5 and has very good coverage...The girls love it and just blew up after switching to this bad boy ...Great light just get it you wont regret it!!!

This is a well built light seems to be working great my plants are loving it

I've only been using this for a week so for now the jury is still out but so far so good. Puts out an insane amount of light right out of the box, I haven't decided yet if I'm going to try to turn it up for flower. Build quality seems to be outstanding and so far my ladies are loving it.

Plants are loving it. You might find this hard to believe but this is my first grow. Only issue is that it gets too hot inside tent. If you dont have enough circulation and fans your small 3x4 tent can get up over 100°F! Ballasts also get hot to touch so I have 2 small electrical fans from a/c infinity pointing at each ballast and I have them on timed to turn on when the grow light turns on. Everything is timed on Gosund plugs.

I am really enjoying these lights. Very bright, and good quality hardware. I ordered two and one's ballast arrived damaged, but the light still worked. The company allowed us to ship the light back after we received the replacement which was perfect for our situation, and very much appreciated. I like that they are adjustable, and easy to use. They do however get super hot as expected.

Great coverage and penetration! GREAT HARVEST! Can’t go wrong with this light it will pay itself off 2 fold in the first harvest and warrantied to do so for years to come! their customer service is very quick to respond and was very quick to send out a replacement.

Be ready to deal with the heat these put off. Voltage adjustment is in an annoying place as well. I unscrewed mine and flipped them upside down to get east access to it. As far as growing I've been vegging and my plants are growing huge. The heat these put off is kind of nice in the winter but come summer I might shut it down.

This LED has high quality drivers and diodes. I’ve been using it in a 4’x4’ tent from seed and partially through flower. Solid growth, no hot spots, low heat output, and no noise. Complete coverage of the the tent. Corner to corner. No complaints or regrets. Recommended.

I use this light in my 4x4 grow tent. Best bang for your buck! Fabulous results!

First light came damaged and after a very slow replacement process, the (replacement) has been going great for the last few weeks and hopefully the light will live up to all the hype around these lights. If so will be adding a few more as I love the simple design and the performance of the light. Special thanks to (((STELLA))) from customer service. She stuck it out and got the replacement process moving and corrected and fixed everything. Hopefully she stays with the company cause she is what customer service is about and is definitely a big reason to stick with the company for future purchases. Again a very special thank you to (((STELLA)))!!

Really amazing product, from a company that is dedicated to improvement and quality. Really amazing light for the price, really enjoy the mist protective layer that allows me not to stress when feeding/watering. If you're looking for a quality QB LED look no further, even their most affordable model still runs the reputable MeanWell driver, and samsung diodes, what separates pro from the expensive competition is their price, top quality product, priced affordably for what you get!

Forget the lights with all of the switches that want to fail immediately after setup. Get this one which is simple in it's design making it far more durable then most. Having great results so far with it, and would highly recommend to anyone looking to upgrade their lighting system. I would, however, add a 315 watt ceramic metal halide in conjunction with this light to achieve full spectrum, and yield capabilities.

The light came in one day early which was fantastic timing! This light is easy to setup and shines brightly! I've seen some reviews where people talk about the metal dropping or being of low quality. The metal feels rather sturdy and a pretty nice thickness. I'll update my review if I come across any issues, but so far so good. This light may seem kind of pricey to some, but just remember you reap what you sew. Totally worth the investment. Just be sure your wires aren't touching the metal. I lifted my wires with a breadtie on one cord and a bungee cord on the other.

This light is incredible. It’s worth it if your concerned about heat and energy. I have a 600 hps also in use and this light is “brighter.” I viewed it as a long term investment and it should pay for it self while saving you money on your electricity bill. 4x4 and 5x5 is accurate. I had multiple lights and returned them for this. Feels like commercial grow light. I now own 5. Which I can connect and control from one light

This light is a beast. It is designed very well and is bright af. It is comparable to the 500w Series 3 R Spec from budget led, and the HLG 550 V2 R Spec. I own all 3 of these lights and this 4,000 is almost exactly the same as the other 2 for much less $. Do you self a favor and save a few hundo and get this over hlg or budget led. The results are exactly the same, very minuscule differences. I pulled over 1 gram per watt in my 4x4 under this pro 4,000!

he light is very well packaged. I am so impressed with this light after only a few weeks that i am planning on getting 2 to 3 more and run 3 or 4 pro4000 in a 4x8 flower tent. lights do and the pro 4000 can take your grow to the next level.

I rarely write a review but I truly feel that the world needs to know how great this light is, it may look like every other LED but it truly is set aside I've tried maxsisun and returned it I've tried Taurusy 4000 and returned it, only to come back to bestva..... the results speak for there self. Heavier buds, frosty as all out doors on Christmas and the aroma my God ... it really makes a difference when using the right light. This will be my third purchase of the bestva pro 4000 don't waste the time I did trying to see which one works best. Hands down it's bestva. Best bang for your buck!!!!!

I was leery to switch from HPS to LEDs but after months of research and talking to other growers we decided on this model. I have to say, I'm very impressed with the brightness and footprint of the light. It's very sleek and doesn't take up much room. Doesn't seem to run too hot, so far, I'm very pleased with our purchase.

No rookie lights right here look no further. Very powerful basic fans will not do if you plan on maximizing these Jewlz. Infinity fan per light. Get your self some good glasses 2 because even stevie wonder and ray Charles can see when these lights come on. Control the bord temp I recommend infinity fans per light at 50 to 60 does this well. And be prepared to sweet under these lights. Might tan u. With Samsung Electronics incorporated how could you go wrong

High output, low energy consumption. The claims that this light gets too hot worried me, but ignore them. This thing puts off about the heat output than a 400w HPS, but it's light output is comparable to a 1000w HPS. Heat is almost a non-issue compared to HID lighting. So far I like it. Lots. We'll see how it fares with longevity.

Its bright

So far so good this thing is bright and I actually doesn't heat up as you might think in my 5x5 tent with a 6 AC Infinity exaust fan with a carbon filter set on 5, that was at 60 F after runing the tent with no extra fans inside and the tent closed only raised it 6 degrees, withthe light as far up as i could bring and thermometer at 20 inches of the ground Will be updating as the garden grows. Recommend buying eye protection!

This light is awesome especially for the money I'm telling yall you wont regret it! Saves tons of energy and heat goes way down. I've been using these steady for 6 months now and not an issue. And bestva company has been more than great with customer service and appreciation to there customers! Each time u order a light they leave u a card in the box that says email them for a special free gift and they offer you 5% off your next purchase OR a FREE 5x9 smell proof bag that seriously blew my mind and actually works!!! I cant say enough about there customer support and customer appreciation/satisfaction. The lights are just killing the game

i’m a huge fan. i got 1 to test out in my 8ft by 4ft tent(i only had plants in half) and during veg the plants LOVED it. during flower i messed up the calculations for my nutrients and i was feeding less than half than i was supposed to and the plants slowed their growth. but my cousin also grows using these and did a side by side comparison with traditional 1000w lights and the ones under the pro 4000 seemed to give a higher yield(even if they gave the same it uses less than half the energy) i ordered 11 more of these lights and am setting up my room right now. the lights do get pretty hot tho but i believe when i start using 220 they will cool down a bit.

I'm no expert. Just a home hobbyist. These lights are like staring at the sun. My plants in my 4x4 tent are all thriving. The price is great compared to what's on the market and I'll never need to upgrade again.

easily the the best value for the money, I really wish i had another 600 dollars to buy another one. HLG sell quantum board set ups that will run you 800 dollars plus for a similar foot print fixture if you want it to come with drivers and they only have a two colors of diodes and you run the risk of it coming in damaged and them not responding to your e-mails like what happend to me. the boards are also less than half the size of the bestva boards, and with all my fans in my tent the bestva also runs at 89 degrees while the hlg is at 101 degrees and its smaller with a massive heat sink lol, i payed 460 dollars on the hlg v2 r-spec 3 pannel heatsink board kit after buying the meanwell driver for 108 and buying a cord and wire to wire it, it is a good light but the bestva is far better takeing only one 4 pannel an one 2 pannel versus 4 hlg fixtures to properly light my 8x4x6 tent

I could not be happier with my PRO-4000. A friend of mine gave me the hard cold truth about my growing. He said my lights suck. After coming to terms with that after just recently purchasing my lights I began my research. After researching several lights I landed on this one. No, it is not the cheapest nor the most expensive on the market. It is however incredible and the results speak for themselves. As soon as I had the light installed and turned on I could have sworn one of my plants leaned over and gave me a high 5 ;) I've had this light less than a week but the impact it's made has been significant. I'm already looking to purchase another for my second tent. I've now tested three lights from three different manufactures and without a doubt, this light is playing a different sport (not even game) than most other LED's out there. I should also mention that I needed to work with their customer service already. No issues with the light at all, I had a separate issue with a discount not being applied. Sunny had my issue resolved in less than 24 hours. His email also felt very sincere. I will absolutely be purchasing from BESTVA again. Matching a great product with great customer service is a dying art nowadays. Thank you Sunny, and BESTVA I am a very happy customer.

Lights work awsome. Seems to be about 70% 3k, and 30% 5k lm301b diodes.
