20 Best Led Grow Light For 4X4 Tent (2022 Updated)

I have owned some of the first generation of these lights. A friend of ours recently purchased a set of these,the first was a little longer shipping but he was informed his that this was a possibility? The second came with in a week of the first light.

These are a look at a true performance light I have seen that lights will be in the near future. Great system,no different than any AC Infinities products. As we grow older and wearable parts keep wearing! The circle of a growers life? If your just starting out,,,great products and for every growing lights,tents,and anything you have seen! We grow inside,I love the bag appeal on our product.

When I make with our old lights are still a more precision developed lights. This as I mentioned before,,every product AC Infinity has created or just made better you or friends will find these on the AC Infinity web site.

God Bless. The best part,,it won’t cost anyone a arm and leg purchase,there is those low balling stores,you know the kind that come and go?.

This light is kicking a m/h ts1000’s *** in a 3×3 side by side comparison! I have never seen a foot & a half fallen over stretched seedling stand back up on it’s own; wish I could show pics. Not 1 plant has stretched that began under this S22 light; both tents are set at same heights, intensities, and maintained in corresponding environments.

Plants moved under the S22 that stretched under the TS1000 have stood up, ceased stretching, and are LOVING this light! AC Infinity has the BEST customer service by far, so I feel great giving them my money; I cannot wait to buy their upcoming products!! Thank You AC Infinity!.

AC infinity provides high quality at every single step. The tent is a step above, zipper, material, fan controller mount, everything works. The light is very pure WHITE. The plants are thriving!! A great hanger setup on the ionboard, much better than others.

I had the light installed in a few minutes, installing solo. AC infinity has my vote for great and best grow tent equipment. Keep up the great work!.

My husband needed his light cart back to start seeds for the garden, so I needed an alternative for my rosemary, thyme, chives, etc. We have cats so the plants have a better survival rate in our basement.

At first I wasn’t sure if this was going to work. The color of the light is much different than our full spectrum bulbs. Also the light cast makes the plants to look brownIsh. But my plants are so happy! I dare say they are happier than they were using my husband $200 grow light/cart.

This is a great buy that works well.

These things are pretty neat. The flex arms are perfect and hold their position well, though time will tell if that stays true. The lights are a bit weird, with the blue/red, and make the room look strange.

I wish it was just white. They are bright, however. The timer is okay, but only allows 3/6/12 hour settings, and you can’t pick the start time for them. Meaning, you press 6 hours, and 6 hours is then locked in to start at the moment you set it.

Some more functionality in the timer would be nice. However, in an apartment with no windows, these things are keeping my plants looking amazing through the winter, and I do not regret buying them. Upgrade the timer by just a bit, and it becomes a solid 5 star product.

Have recommended them to friends and family already.

Growing some herbs indoors to keep the isolation covid/winter blues away. Followed recommended instructions on the back of the package regarding seedlings (about 8″ above, at least 14 hrs light) along with covering the pots with plastic wrap/film to keep soil moist during germination process.

All the seeds sprouted around or under 5 days (twice as fast)! So far so good, will have to wait and see how well the seedlings grow.

I received these lights to replace bulbs in my can lights. When I used the lighting in my kitchen before these you could feel the heat from the floodlights almost immediately. These LEDs solved that problem completely.

I bought them to try in the kitchen and there was such a difference I ordered more so I can change the bedroom lights and the living room lights. They are smaller than the standard floodlight bulb but look fine, and are bright, perfect light.

I am a frugal shopper, and often I buy generic brands. This is not a generic product, but I buy this on the regular. I like that this helps save money, that is my main goal. These light bulbs last for a long time, and give off a great glow.

These are perfect for any light socket that fits, I use them all around the house. I’d definitely recommend this product.

Seedlings love this grow light! After they start growing, I move the seedlings to LED clamp lights because I want to grow more seeds. If the seedlings are very slow starting, I keep them under this system because it is their best chance.

It is great to be able to put water in my trays without moving the seedlings or young plants plants around unlike the LED clamp on system. Very easy and effective way to grow seedlings. I’ve had no problems.

I recently moved to New Mexico and live at 7000 foot altitude. The day time temps are sunny and are in the high 40 to 50 degrees, but night temps drop well below freezing until the end of April, early May.

Yikes!! In Texas, I had 8 months of growing season, but in New Mexico, I only have 5 months. In order to maximize the growing season here, I needed to start my seeds indoors. I ordered this grow light and within 3 weeks I had significant growth from my seeds.

Very delighted with the outcome. I am seriously considering using this light year round!.

We have the smaller 2 and decided to get the 4 for starting our flowers and veggies from seed. Awesome product. Love the stand, we have a few other home made pvc stands and this one of by day the sturdiest.

Very happy with the purchase. Plan to use it for years to come!.

Ignore dumb reviews and consider these LEDs. first, two quick things regarding silly reviews: 1) Being sent an incorrect or damaged (in-transit) product isn’t a legitimate reason to review a product poorly.

Rate the business or shipper poorly instead. Or shop at a more specialized store that knows what it’s shipping. 2) Using an INDOOR light OUTDOORS and writing a negative review because it “filled with water” after rain is both funny and sad.

Believe it or not, these INDOOR lights won’t actually fill with water unless they are literally kept outside during rain. 😐 lol I’ve been using these (from a different source) for 2+ years now and they are mint.

They perform well, don’t get super-hot, and grow plants from 12-24in away without much issue. They are super-bright day spectrum LEDs though, so don’t expect the blurple hue found elsewhere. PAR specs are halfway decent too, although a little weak towards the red-end of the spectrum.

If you are looking to grow plants farther than 24in away, you’ll need to double-up (or triple-up) with these LEDs. Don’t expect a huge energy savings vs. T5HO, considering there’s only a 6W difference between 48in models.

They work great, really good for leafy plants Giving 5 stars for the bulbs themselves. They work great, really good for leafy plants. Because they aren’t LED, they do give off some heat, so keep that in mind.

The only gripe about Sunblaster lights, in general, the metal piece you have to install to allow for you to hang it off a chain or cord is really hard to put on, you have to struggle to get onto the light.

Just a note for Growbuds fulfillment centres themselves. I had to return this product twice since both times they arrived broken. The first time, completely smashed, and the second time the filament was broken.

The light itself came with with just some paper as protective packaging. I’ve been sent other items by Growbuds that needed less protection with better protection that what was given in these 2 instances.

I suggest bubble wrap or those air cushions that you use with pottery. The bulbs themselves are glass and easy to break if not properly protected.

I had my best indoor start with tomato, pepper plant seedlings and lettuce ever. I have the light set with the sunblaster. The plants were straight and grew very strong stems. No more spindly weak plants that needed support as soon as they were transplanted.

Arrived within 3 days in custom packaging that shows its a quality product and looks built to last years. Upon opening the panel it has the Spider Farmer markings and the build quality looks fantastic.

LEDs cover the board over what is a white background of highly finished coating. Two Meanwell drivers power the board with adjustable dimming options and the option of linking two or several units together.

Love the dimming option and the whole panel has 2 easy to assemble mounting cables with adjustable hangers, panel is nicely balanced for horizontal hanging. From initial power on the footprint was as expected for an LED board and although the lighting panel cost more than its HID alternative the extra lifespan, cheaper costs to run and less heat to deal with mean it should pay for itself within months.

I like it so much im considering getting another one as previously stated the footprint is less than its HID alternative but the board should run a 4 x 4 foot grow area with ease. Conclusion:- Quality Built Product, Dimming and Linking Option Is Great, Would Recommend A+++++++++.

Ive been using the purple color LEDs for about 5 years. The whole time thinkin I was getting the most bang for my buck. wrong! Quantum lighting is the way to go. Been running it for 3 weeks and can already tell a considerable difference.

Super bright, adjustable, and very little heat. Like the title of this review states, I wish I would have purchased a long time ago. So stop just looking at them in your watch list and dreaming, just buy the damn thing, youll be more than satisfied! If not, youll be left behind by all of those who do.

I bought a SpiderFarmer 4000w to replace my 1000 MH in my Moon Cabbage vadge room. I LOVE IT!!! I bought another one that I will use to replace the 1000 HPS in my Electric Lettuce flower room, and I’m going to by ANOTHER one because they use WAY less power than HID lighting and the LED’s run SO COOL that there won’t be a heat problem in my either of my rooms next summer! Thanks SpiderFarmer! You ROCK!!!!.

Everything about this was exceptional! The quality, the packaging, the instructions, and the variety of contents that you get. As soon as it arrived I knew that I would be buying another grow tent kit but even bigger after I broke this one in.

The hardest part of the whole thing was figuring out how/which way I wanted to have the exhaust fan, duct, and carbon filter. I might have missed it on the actual fan but if perhaps the fan itself were labeled with a small airflow direction indicator that would make it even easier.

Just be prepared that you might have to make some adjustments but other than that no complaints. It has definitely been engineered and manufactured to last. Plus the controller and app behind the whole thing is great! So easy to use and setup the different settings from timing of lights to how frequently the fans run or what temps and how hard the exhaust will run.

If you’re looking for an all in one setup look no further. Should you have questions or concerns customer service was great!.

This Grow tent kit is hands down the best kit you can get anywhere! The quality is grade A top premium, the equipment is top notch, the price is easily understandable and compared to the other others way more doable.

It’s compact size make it perfect for one plant and easily capable of stashing in a small closet or laundry room. I love it and I am already planning on getting one of the larger ones just for the luxury of doing multiple plants at the same time.

Oh yea definitely gonna upgrade my controller 69 Bluetooth to the 69 wifi as soon as it’s available to order.

I knocked a star because I wish the company would offer options to upgrade certain components of the kit like the light, as 200W isn’t sufficient enough if you want to try and go crazy with your grow; using everything to its max capabilities.

Other than that, everything is very solid and really enjoy this tent. I used a discount code for 10% off the entire purchase and was able to get the silencer included after shipping($629). for less that what I would have been paying (692) without the discount.

Codes are all over youtube and google if you spend 3 minutes looking.

IšverstiShow in original languageArrived on time,nice and compact 600 watts led light,done a few tests and also watched many reviews on you tube. Does what it says and at an affordable price. If your after a cheap light on electric and good power this is the light for you.

Great for beginners to pro.

IšverstiShow in original languageAmazing value, for any hobby growers this is a game changer. Slightly lightweight construction but with the price understandable. I’ll be buying another.

IšverstiShow in original languageWhat a great product!! It came securely packaged, it was very easily assembled, the light spectrum is impressive more like sunlight than traditional LED”s. I have metered the power consumption and it was a little higher than advertised but not by much.

Overall very impressed and will be recommending to friends.

Great Light with high PAR output I rate the light 4 stars out of 5 only because they have to keep overhead low and prices down to keep a lock on the bottom tier lights. If you will note they will give no info or insight on the overall CCT “color” of the light overall.

These are great to get the job done for a cheaper price. I only wish they would start a panel light series with more IR and addition of UVB diodes would be great to make the lights better for flower than veg.

The only downfall to these lights. Due to the lack of UVA/B diodes and running the minimal amount of Red and IR extends the plants life cycle and makes it take longer to finish. Other than this, what keeps the price down, they’re really unbeatable.

Just don’t try to get than cct report ? Maybe it’s too far from optimal 3500k to mention. Or maybe R&D is slipping? either way buy, learn, practice and probably move on unless they start a new series.

I’m crossing my fingers and been asking them as well.

I have had several LEDs and Im really liking the full spectrum white lighting thats out. I also like the pinks. Hmm. I however went with a bar type setup for uniformity and because I didnt like the rectangular shape of the xs/p series 2500/4000 lights.

Had they been squared I probably would have stuck with them, but Im definitely not upset with the competition. There are some really good lights out there and I had to do a lot of research. great starter/veg light.

I still use it for vegetative gardening, but I use my Ze510(which is a steal) and supplemental lighting for fruiting. Amazing veg light. Good fruiting light. Would I buy it again – no. Would I recommend on a budget – absolutely.

Would I say save up or aim higher – honestly – most certainly. Im an honest type. some stiff competition out there with great rates and Love the friggin heat sink on this thing though. Great value item.

The top-line just isnt there on the higher end items compared to others.

Compared to other 2000W grow lights, this light had more LEDS than all the other lights I looked at. It has a dimmer knob so you can give the exact amount of full spectrum light to your plants. Comes with easily adjustable hangers.

My plants love the color of light that this grow light puts out. They have grown more in the first week since I’ve been using it than in two weeks of prior growth with my other light of the same wattage.

Worth the money!!!.

Hello a while back I purchased 2 hlg650r lights. Your communication during the process was perfect and the lights are amazing. However there is one thing. one of the lights was missing the hanging hardware.

Not the ratchet hoists but the ones that connect directly to the lights themselves. Not a huge thing I was able to rig something up but I do believe that given the premium lights that these are they should have been complete.

I’m still going to order stuff from y’all but just thought you should know. Thanks Doug.

I own two of these currently and they are performing great, i will be getting two more. I say for the price they cant be beat in overall price to performance. These are 300w quantum board lights and they measure out to 301W drawn on my meter when maxed out.

Im used to growing with what are now called blurples and Cob lighting, before that i used fluro and mh/hps. Now im here growing with just one light board that is capable for all stages. So far the plants are loving it, i dimmed them to 150w for veg using the screws on the drivers and a wattage meter and have them placed just above 2 and a half feet and have it vegging a 4×4 area.

For flower they should do fine at 220w and lowered to 1. 5-1ft then raised to 300w after 3 weeks. Your results may vary but this will work perfectly for me. Cons? well the dimmer control is limited by you having to use a screwdriver to turn it other than that there are none that i have come across so far in my use.

If your looking for what to me seems like a great quality quantum board then look no further.

good light, i get 3’x3′ consistant canopy in veg, nice color light easy to read plants. tight internodal spacing. dimm w set screw isnt as easy as dial, but cant change setting and forget to tune back up like i do w dial dimmers cause only change setting when u really need to.

better than most.

These lights made a huge difference in my plant. This is the second one I have purchased. As long as they have the quality they have now Ill be buying more.

We recently had a sunroom enclosed and the glass is UV protected so my plant were not getting enough sun nutrients. I added a couple of these lights on timers to run them while we were not using the room and my plants have exploded.

also we bring our citrus trees in during cold months and they all blossomed and are growing like crazy. i loved the light so much i also purchased a few more to put in my green house for winter months.

what a difference!!! i grow fresh herbs in one green house all winter—Fantastic!!!.

The units were easy to install and operate as described. The plants seems to ‘love’ the energy these lights generate as they are going much faster than I expected. One comment – monitor the plants carefully as the the distance from the plant to the grow light can cause the plants to wilt if the heat from the light is too high.

I have had to make adjustments twice.

I purchased 24 of these full spectrum LED lights and use them over the winter for our numerous indoor houseplants plants. While the plants spend the summers outside must be brought indoors for the cold winters here in Minnesota.

These lights keep my indoor plants very healthy and vigorous during our dark and cold winters! I highly recommend them!.

I’ve wanted a bar style light for a long time, but they were too pricey! Mars Hydro would not be my 1st pick, but they have stepped up their game. Light seems well made, but the instructions were lacking, and the dimmer doesn’t work.

I will be sending it back.

I own one of these, bought it in a crunch, a. c. broke and hps was pushing 90 degrees. This light rocks! It changed my view on lighting. It’s super bright, super cool and quiet running, well made, energy efficient and affordable.

One will fill a 3. 5×3. 5 tent with flowers. Two could probably flower 3. 5 x7 or overlap to 3. 5×6 nicely. The reflector approach works really well, bounces light everywhere. These lights effortlessly germinate and pull up super healthy plants, something harsher lights can’t do.

Yes, I would definitely recommend these to my friends, including my friend Bruce Lee.

After watching a few set up reviews I was a bit puzzled on the driver mounting brackets being deodorant them all the ones I I’ve seen. I did some research and apparently the secretly updated all the newer models and I received the most up to date model.

IšverstiShow in original languageI purchased the FL1. I wish they had this light out when I purchased my last light. These lights are outstanding. I have other leds and for the price this light is a steal!!! I would definitely buy another light if needed and I would and tell everyone to take a look at volt lighting.

The price is right and the equipment is solid built, discreet shipping, insane power and great customer service. Can’t say enough about this light.

IšverstiShow in original languageThe only complaint that I would have at this point is the false advertising that they would be shipped discretely. They were not. If there are those worried about this you probably should order elsewhere.

They did come packaged safely and there did not appear to be any damage. Got them installed with no problems. So far the product is functioning as it should. They are definitely very bright. As far as long term function will have to see.

IšverstiShow in original languageI’m an amateur grower but have been getting more serious and wanted to invest in a high-quality light. I ordered 1 FL-1 for a home grow with 6 plants in a 4×4 tent. This was the highest output light I’ve used so far and I could definitely tell the difference when my plants started to bloom.

I got the highest yield I’ve gotten so far and had no issues along the way. Hung the light about 6-8 in from canopy as directed and was afraid of the plants burning, but never happened. The dimming knob was also great so I could use the same super powerful light for veg too.

Would recommend to friends or anyone looking at this light.

as i unboxed the ts 3000w, there was no assembly instructions. when i tried to assemble it after a couple you tube tutorials, i discovered that the driver layout was ok but the mounting bracket fo the dimmer was intalled where there is no way to attach the dimmer housing with out cutting part of it off.

as this was only the first of 5 units i purchased, im hoping for the best in not experiencing similar issues.

I was looking to try a new led grow light. A friend sent me the link for shopgrowspaces. com Mars hydro performs great. I placed my order very easy got my product fast and am extremely happy with the quality and customer service.

2 thumbs up.

A friend of mine has a Mars TS 3000 and as soon as I saw it, I knew I had to have one. Or three. So I bought them here at FactoryPure because it was the best price around and I couldn’t be happier with the service.

The lights arrived very quickly after I ordered them and setup was a breeze. I don’t know if I’m imagining it or not, but my plants look even better after only one day of being under these lights. So glad I made this purchase! Thank you!.

I received product reimbursement in exchange for my honest review. I thought the Great Value LED plant light was so neat. I am currently using it for some microgreens I planted inside the house. The lights are on two flexible arms but I wish the clamp was a little easier to open; it’s a bit tough for me.

The controller allows you to turn the lights on and off, change the level of brightness, color lighting, and has timing modes of 4, 12 and 16 hours. This has many more features that I thought and is such a cool light.

I’ve never used one of these before but would be open to buying more when I have more plants I want to grow indoors during the winter. I would recommend!.

I love these my plants have been doing so much better. They are growing so healthy. I really like that you can dim the lights they have 3 different colors and a timer.

This is my second KIND LED light. Lighting performance appears to be what I expected. The remote timer system, on the other hand, is one of the worst designs I have ever seen. It takes a massive amount of time to set the timers, having to scroll through each channel, and when all I want to use it for is flowering at 100 percent intensity on all channels, it is a massive pain.

And on top of that, if I try to turn off the timers and let my external timer do the job, the light won’t default to the intensity setting I had before it was switched off (which was 100). Instead, the respective channels seem to randomly default to something else.

I thought having this additional control and eliminating a timer from my setup would be great, but this just isn’t worth it. I wouldn’t recommend this light to anyone.

Holy crap this things cool! It only runs at 45 c in a 4×4. The footprint really is 4×4. I love the features of the system. Only critique, the remote has no lanyard. This just dumb. 1200 dollar light with a tiny, loseable remote.

Adjusting the settings on the unit is a lot harder to do without the remote. I use velco. Stick one to the tent and one to the remote. Problem solved. Oh, and its a good light too.

Great grow light! A little confusing setting up the timers but that was probably user error. They are working great and the plants love it. Thank you

These are simply bright lights that give the plants exactly what they need – LIGHT. The versatility of these lights are endless and they last for years. Running some of these for over 3 years, 12 hours a day and still working flawlesly.

I have several flat against a wall, to give light to hanging plants; I have others under cabinets, some in greenhouses, some hanging above plants, some to enhance terrarium light. The thinness of the panel makes them extremely versatile.

I’ve been ordering these flat panels from apluschoice for several years and while the price has increased slightly, I still find these lights to beat out the fancy so-called grow lights, with dimmers, fans and other unnecessary gadgets.

I have over 300 plants in my house and yes, I use other lights as well, but these panels are my favorite and judging from plant growth, my plants are happy with them too. Don’t get roped in by “gadgets” on grow lights – get something that actually works, like these panels.

I bought these for my Venus Flytraps, which require a minimun of 4 hours DIRECT sunlight. I was skeptical about buying them. However I’ve had them under the leds for about two weeks now, their new growth is healthy and has very good coloration you only get with bright light.

These leds pull 22 watts and are very cool. I have them completly covering a fishtank. (to keep my cat out) and the fishtank only gets to about 85 deg F. and its August in AR. I receved 2 panels unharmed however.

I am still waiting on a replacement for a third that was damaged in shipping. the panels are shiped in a bag not a box. with alot of shiping being automated the chances of it being crushed by another shipment are probably pretty high.

Giving 3 stars for now as I just received the unit and already am not impressed. THE GOOD: -The light is very bright and my plants appear black under it, so I hope it will help my plants grow in the next few months, only time will tell).

-It lights about a 16″x16″ very well and less so further out. -Very simple. No buttons or control. THE BAD: -The light is VERY thin, so much so, that it was warped before or during shipping. This doesn’t affect its ability to turn on and off, but was difficult to hang with the weird warping.

-No hanging kit, clips or any other accessories included. Disappointing as I thought a mounting kit was included (I used fishing line and a ceiling hook I had on hand) -No power switch so you must unplug to turn off (which is only a pain because of where I have my plants set up).

-Very simple. No buttons or control. (I listed this as both a pro and con as some may like the simplicity).

This clamp grow light is perfect for in home use since it looks modern with it’s nice white finish unlike the more common aluminum reflectors and bulbs that you can also buy but look like it belongs just in the garage.

I grow flowers from seed near my large sunny windows but on overcast days when there is not enough sun I use two of these lights to rotate my plants under and give them a boost so they don’t become weak.

I have also started seeds under these lights and am now even trying to grow some mini pumpkins and watermelons in large pots. I also have other daylight spectrum lights from another company that specializes in craft/shop lights and I’d say that if you want to use these lights in a shop when not using them for plants it would be fine since the white light looks just as crisp.

I have also heard no humming which is important in the house since if you are close to the lights humming can be very annoying. Overall, I’m glad I chose these!.

The electric design looks adequate as does the heat transfer from the LEDs. However the mechanical design has some internal weakness and construction challenge. The power cord is robust but terminates to the PCB with a friction fit connector latch rather than soldering.

The PCB is held in place by one long plastic standoff that can fracture. I have two of these that I had to repair due to loose internal power connection and standoff fracture. They have performed well for six weeks of 14 hours of daily use.

The light spectrum produces good growth. The metal body is strong and the paint remains well bonded.

I am very pleased with this excellent lamp. the clamp is heavy duty. I clamped it onto a floor lamp so it would shine down on my plants. I have been searching for a full spectrum LED lamp forever for my indoor plants.

succulents and orchids. I sent photos to my fellow master gardeners but I can’t figure out how to include a photo in this review.

If you have the space in your room this is a great light to have. It’s got great coverage when hung high and grew 7-8 ft plants for me. If running more than one at a time you will need AC. The controller is also a must have to get the most out of the light.

EXCELLENT light. As it’s little brother the ROI-E420. Great spectrum, low heat, and efficient. Im on my second grow and I have seen unbelievable gains throughout my grow.

This light is so damn bright and the girls LOVE it! Highly recommend this light. Noticeable increase in density and terms. Excellent customer service and warranty.
