4×4 grow tents are perhaps the most popular-sized grow tents out there. They have a clear advantage over the other major sizes such as 2×2 and 6×6 or 8×8 because while 2×2 is too small, 6×6 and 8×8 are too large and will take up a lot of space inside a room. 4×4, on the other hand – hits just that sweet spot. In this article, however, we talk about a very special element that you need with your grow tent. We take a closer look at the 10 best LED grow lights for 4×4 grow tents.
Why we thought it was necessary for us to write an article about these grow tents is that there are practically hundreds of options out there for LED lights of a tent this size. This is what we have gone through hundreds of grow lights to choose the ten best options for you! This is a definitive list of the top ten options that you have when it comes to buying a grow light for your 4×4 grow tent.
We have selected these grow lights on the basis of performance, price, and features. Our focus has also been on futureproofing our readers – so we’ve chosen most grow lights that follow the latest, most modern of standards, and can last you for years to come. A grow light is a long-term investment and is usually something that can last up to a decade if used with care.
Lastly, in addition to all this, we’ve also made it a point to not include any HPS/MH/Fluorescent light, and have gone only with LEDs, which offer the latest standards of lighting, are safer, consume less electricity, and operate at cooler temperatures. With that in mind, let us take a deep dive at all the best options available to you:
10 Best LED Grow Lights for 4×4 Grow Tents in 2021
Here’s a list of the ten best options for you if you are specifically looking for the best grow lights for 4×4 grow tents. These lights aren’t really ranked in any particular order and we’d request you to go through all ten of them before you make the final purchase decision so that you get a better idea of the various different kinds of products out there.
- 4000 Watt LED Grow Light
- Consumes about 450 Watts of power from the wall socket
- Coverage offered: 5×5 ft (flowering), 6×6 ft (vegetative phase)
Spider Farmer is as good as it gets when it comes to the world of LED grow lights! The company is known for making some of the best grow lights with the latest standards of lighting and safety. This is the SF-4000, which is a large, 4000 Watt grow light from the company – however, when you look at the amount of power this consumes, you’d be shocked. The light consumes only about 450 Watts of power, and offers you almost twice as much coverage as you might need.
The grow light offers a vegetative coverage of about 6 x 6 ft, and flowering coverage of about 5 x 5 ft, both of which are more than enough to suit your needs in a 4×4 grow tent. At an output of 4000 Watts, you can assume how bright these lights are going to be! In case the lights seem too bright for the size of your tents, there’s always the option to dim them in this grow light, which is a major advantage. The light operates at 2.7 umol/J, which ensures a very high energy efficiency.
This light provides you with a full-spectrum lighting system, which is great for your plants. You get the reds and the blues, which together help your plant get the best results right from an early stage, all the way to the flowering stage. Another great thing about these lights are that they are quite lightweight as there’s no fan behind them.
However, don’t mistake the lack of fan to affect the way these lights cool down. These lights don’t heat up at all, and are among the best options for someone who wants a silent and noise-free experience. Anyone who has used grow lights even for a small amount of time would know that it can get quite cumbersome if there’s a large fan attached to it, especially if you’re sleeping in the same room. Thankfully that won’t be a problem here.
The lights are designed really well, and use top-quality hardware too. The LEDs used here are made by Samsung (LM301B), and they also make use of a reliable MeanWell driver which helps you get the most lighting per watt. Last but not the least, this grow light also supports daisy chaining, which is another added advantage for those growing at a large scale. You also get a three-year after-sales warranty when you buy this grow light.
- Extremely large coverage
- Lightweight, easy to set up and easy to adjust
- Does not heat up too much
- Noise-free operation as there are no fans involved
- Supports dimming the lights
- Very expensive
- 1000W LED grow light
- Consumes 100W from wall socket

There simply cannot be any list about LED grow lights without including at least one product from Vivosun. The company has constantly been coming out with some of the best lighting solutions out there, especially for indoor growers who like to grow cannabis plants. This is a 1000 Watt LED grow light, which is a great offering for anyone who is looking forward to a light for their plants without blowing a hole through their pockets.
The grow light features LM301H diodes, which are made by Samsung. Along with these high-quality LED lights, there’s also a high quality Sosen Driver that is used here, which ensures you get the most out of your grow lights and don’t end up paying large sums on electricity bills. This is a full-spectrum LED grow light, which ensures that your plants get sun-like lighting which includes the red as well as the blue spectrum of lights, suitable for both the phases of growth.
This is a high-efficiency grow light (2.75 umol/J), and it is actually quite bright. While you might think that a 1000W grow light won’t be too bright, this one can really surprise you. It is so bright that you actually have to use sunglasses while working around it. But don’t worry, you don’t have to buy a new pair as Vivosun packs one with the light!
There’s a dimmable ballast on this grow light, which allows you to increase or decrease the brightness with the help of a knob. This is a really important feature that is often missing in lights under $150. The ballast has four dimmable levels – 25%, 50%, 75% and 100%. Another good thing about this grow light from Vivosun is that it does not heat up too much, and hence does not require a fan. The added benefit of being a fanless grow light is that it does not generate too much noise as well!
Also when we say that this grow light provides you with 1000W of light, it does not mean that it consumes that much energy. It draws only 100W from the wall socket. The grow light comes with rope hangers and a six foot long power cord, and is pretty easy to set up. Lastly, there’s a three-year warranty on the light.
- Operates at temperatures that don’t flare up

Maxisun may not exactly be Vivosun, but it is still a pretty good brand. This is a large grow light, offering you a 4000W output. This is something that is meant for large-scale and professional growers. The PB4000 Pro from Maxisun covers a vegetative area of 5×5 ft and 4×4 ft during the flowering phase, making it one of the best grow lights for 4×4 grow tents. It delivers above and beyond what is typically expected of it.
While there are many good things about this grow light, the thing that impresses us the most first-up is the fact that it comes with a remote that allows you to adjust the brightness from 0 to 100% and dim the lights when needed without actually having to touch the light. In order to provide your plants with the best possible lighting experience, the grow light makes use of 1400 high-quality diodes manufactured by Samsung! Talking of high-quality parts, this light also makes use of MeanWell drivers, which are really long-lasting.
This is a very bright grow light so make sure you’re working with a pair of sunglasses while you’re around it. The light offers a total output of 4000 Watts, but draws only 400 Watts from the power socket, which is a huge energy saver. This can achieve results that are equal to or even better than what an 800 Watt HID light would give you. Another benefit here is that this grow light doesn’t heat up as much as a typical HID would.
The Maxisun PB4000 Pro doesn’t heat up at all, as there’s a series of vents and heat sinks which allows all the trapped heat to escape pretty well. There are no fans placed on top of it, which makes it easier on the ears as there won’t be all that noise that fans tend to generate. The light maintains its cool thanks to a thick 5mm aluminum heat sink. Lastly, you get a three year warranty period as well as a 90-day money back guarantee when you buy this grow light from Maxisun.
- Brightness can be controlled via a remote control
- Covers a really large 5×5 ft area

Here’s a 2000 Watt LED grow light from Mars Hydro, which comes with just about everything that you need, especially when growing cannabis indoors in a 4×4 grow tent. The light provides this output while consuming only 300 Watts of power from the wall socket – which is a huge advantage of using LED grow lights, as they are really energy efficient.
This is a thin grow light, but the build here is a little old-school as it comes with reflectors on the sides. The light is also quite easy to hang and can be set up by anyone, even if they are using a grow light for the first time. These reflectors on the sides actually provide a big advantage to the growers because they ensure that the light doesn’t scatter away and the reach of the lighting is instead expanded.
The Mars Hydro TSW 2000 is one of the best 4×4 LED grow lights because of the fact that it features some really bright lights, featuring 684 diodes in them. It gives you a very high PPFD score too, at about 910 umols per m2/s. When used well, this grow light can easily replace a 600W HPS grow light, while saving you 50% energy on that.
Another advantage of using this grow light from Mars Hydro is that it supports both, daisy chaining as well as dimming – which is an added benefit for growers as you can customize the lights the way you want, and you don’t even have to worry about the cables. The light operates without a fan – which has its benefits as well as disadvantages. It operates noise-free, but it can also heat up at times.
Lastly, this is a full-spectrum grow light. It has both the red and the blue spectrum of lights in it and you won’t really have to change your lighting setup the moment your plants enter the flowering stage from vegetative stage. In addition to that, you also get a three year warranty period here, along with a really good after-sales service in the US. Besides that, there’s also a thirty-day money-back guarantee, in case you are not really satisfied with the way the light performs.

Bloom Plus grow lights are all over! You walk inside any store of repute and you are likely to find these grow lights over there. This is a 2500 Watt grow light from the company, and the first thing that you need to know about this light is that it consumes only 250 Watts off your wall socket. This in itself is a huge benefit as you are getting 10 times the output.
The BP2500 grow light makes use of 646 pieces of Samsung 2835 diodes, which are some of the best LEDs in the markets in 2021. This grow light can easily replace a 400 Watt HID grow light, while consuming way lesser electricity, and also lasting you for a much longer time.

The grow light operates at an energy efficiency of 2.7 umol/J, which is another good thing about it. The light can help you attain a yield of 2.5 grams per watt. Bloom Plus BP2500 is a full-spectrum grow light too, which means that you do not have to change your grow light every time your plant moves into the flowering phase, as you’d do with HID lights where you have to keep changing between HPS and MH lights.
Another major benefit of buying this grow light is that it does not come with a fan behind it, which makes it very silent to operate. People who have used grow lights in the past just know how much of a nuisance these fans can be. However, in the case of these fans, you get a very silent operation. The lights also make use of a thick aluminum heat sink which ensures that there’s no heat up and they operate at cool temperatures. These lights also feature a dimmable ballast, which is another added benefit. Lastly, you get a 30-day money back guarantee, and a 3-year warranty from Bloom Plus when you buy this grow light.

A brand that you may not really have heard of, Abriselux specializes in making modern-day flat-panel style fanless LED lights. This is a very good fit in our list of the best 4×4 LED grow lights because of multiple reasons, but the biggest of these benefits is that this is totally the grow light that you should go for if you are living in a hot region. This is a fanless grow light that operates at really low temperatures, just under 55F at all times.
With an energy efficiency of 2.6 umol/J, this grow light is quite an energy saver! You get a 1500 Watt output, and it consumes only 150 Watts from the main power socket. Besides this, the grow light can easily replace a 400 to 450 Watt traditional light (HPS/HID). Abriselux A1500 is one of the best LED grow lights for 4×4 grow tents for someone who does not want to spend too much but wants a good quality lighting experience.
There’s also a dimmable ballast here, which allows you to dim the grow light when needed. The manufacturer recommends setting the intensity between 40 to 60% during the early vegetative phase and between 80 to 100% during the late vegetative and flowering stages. This is a full-spectrum LED grow light, where you get lights of different spectrums (red as well as blue) together.
The light provides you with a 4×4 coverage in the vegetative phase and about 3.5 x 3.5 ft of coverage during the flowering phase, which is just good enough for someone who is growing marijuana plants in a 4×4 grow tent. Abriselux also gives you a 3-year warranty as well as a 30-day money-back guarantee. The grow light is also available in variants of 1000W and 2000W for those who might want a less or more powerful light. All in all, a good deal for those who don’t want to spend too much on grow lights but still want a good product.

All the grow lights that we’ve seen here so far have a certain form factor to them, which makes them uniquely identifiable. However, the grow lights that we are going to see here are a little different from the usual. These are meant for plants when they are at a younger stage, or they can also be used to provide some additional lighting. Essentially, these are LED grow lights but in the form factor of a T5 light.
The lights offer a decent red/blue spectrum combination, operating at a range of 400nm to 660nm. The light that you get from them isn’t the typical yellow light that you’ve seen in the grow lights above. This is a little different, pink-colored lighting system. These T5 LED bars are some of the best LED grow lights for 4×4 grow tents, especially if you want to use them as a booster mechanism and not as the primary grow light.
Manufactured by Lightimetunnel, these grow lights can actually be programmed based on your needs – 3 hours, 6 hours or 12 hours. These lights will then automatically turn on and off in the pattern that you have set them on, every day. You will never have to worry about turning them on or off manually. The timer is actually one of the best features here. In addition to the timer, you also get a dimmer, as there are four adjustable dimming modes – 25%, 50%,75% and 100%.
You don’t even have to hook each of them to a power source individually as they are connected to each other and only one power cable goes to the wall socket. The lights cost under $50 and are a really great bang for your buck. If you want a 2-pack or a 4-pack set, you can buy them from the Amazon page as well. There’s also a one-year warranty and a 30-day money-back guarantee on this grow light.
- Comes with a programmable timer
- Can be dimmed in four levels
- Unique form factor
- Great to use as additional ‘booster’ grow lights
- Can’t replace a typical grow light and always has to be used as an add-on
- 2000 Watt LED Grow Light
- Draws 240 Watts from power socket
- Provides a 4×4 ft vegetative coverage, about 3×3.5ft flowering coverage
Phlizon is a pretty familiar brand for most people who grow marijuana indoors. The company has been around for quite a while and they’ve managed to make a good name for themselves in a market otherwise dominated by brands like Vivosun and Viparspectra. This is a full-spectrum 2000 Watt LED grow light from Phlizon, which gives your plants a natural sun-like environment to grow in.
Phlizon has not included a fan with this light, which anyway operates at really cool temperatures. This is a big relief as the noise that most fans generate can be quite annoying and doesn’t let you sleep if you’re growing in the same room. However, over the past couple of years those bulky grow lights with fans are eventually being phased out. This grow light can also be dimmed to match the needs of your plants during different times of their growth cycle.
The grow light provides a very bright lighting experience, thanks to the 1152pcs of LEDs that are used in it. We strongly recommend using sunglasses while working around this grow light for a prolonged period of time. The core body of this light is made of aluminum alloy, which is lightweight as well as durable.
One more thing that this grow light takes care of is water damage. Since water is a common element involved when it comes to growing plants, this LED board makes use of sealing technology to ensure that there’s no way in which water can creep through and damage it. Lastly, you also get a three year warranty with this grow light, as well as a 30-day money-back guarantee.
- Consumes very little power
- Very bright lights, help you get a high yield
- Supports dimming the lights when needed
- Fanless operation, creates no noise
- 3-year warranty period
- Heats up quite a bit

Skylaxy is a name that you probably haven’t heard of before. However, the grow light that this company has come up with is actually pretty good. This is something that you might not use as a standalone light for big plants, but it is a good option for providing an early start to your seedlings, or for using as a flower-booster during the blooming phase. These are 75 watt grow lights, which come in a pack of two, giving you a total of 150 Watts of output.
The grow light covers an area of 3×3 ft, and has to be kept pretty close to the plants. You shouldn’t worry about the plants getting damaged or burnt because there simply isn’t enough heat generated here that can possibly damage the plants. There are 225 LEDs used here, with a majority of them being red and a few blue, along with about 9 white lights. Overall, this helps your plants grow really well across all phases of growth.
These lights can be programmed using a timer, which is one of the best things about them. This is particularly beneficial if you aren’t really using them as a primary source, but as a secondary lighting source. They also come with a 12-month warranty period, and as always, Amazon has a really good return policy if you aren’t happy with the performance.

- Do not generate noise

Last on our list but not least of them all is this very thin grow light from EnFun. The grow light offers you a total wattage of 2000 Watts, but consumes only 200 Watts off the main power socket, which is the biggest advantage here. This is perhaps the best light for 4×4 tents, especially if you’re looking at something that’s lightweight and portable. There are 576 pieces of LEDs attached to the light, which make it as bright as it is.
Another thing to note is that the EnFun FS-2000 is a full-spectrum LED grow light, which means it provides the best possible lighting experience that your plant can get. It’s got everything from the reds and the blues to the whites and the yellows, giving you a very balanced lighting.
The light operates in a noise-free manner because there’s no fan here. In addition to that, you also get a very strong performance from the 10mm heat sink, which helps keep all the heat away. This is a really thick heat sink, but not one that weighs the product down. This makes sure that your plants get more light and less heat and that they don’t get damaged in their vulnerable stages.
The grow light provides a coverage of 4×4 ft during the vegetative phase and about 4×3.5 ft during the flowering phase. Summing up, this is a pretty good option for growers who don’t want to go for the mainstream brands but still want a product that looks good as well as performs really well. The EnFun FS-2000 comes with a three year warranty period.
- Extremely lightweight and easy to set up
- Great heat dissipation via the 10mm heat sink
- 3-year warranty period
- Can be dimmed as per need

Frequently Asked Questions (FAQs) About LED Grow Lights for 4×4 Grow Tents
Here are the answers to some of the most common and frequently asked questions (FAQs) about LED grow lights, particularly when it comes to lights that are used to grow weed inside a 4×4 grow tent:
1. Are there any special considerations that are to be made when selecting the best grow lights for 4×4 grow tents?
The primary thing that you need to keep in your mind is that it needs to be sufficient enough to cover the whole tent. Getting a light with coverage between 3×3 and 5×5 will be well suited because the tent has reflective walls and it amplifies the light anyway, so it is ok if you go with something that is a little smaller. 4×4 would, however, be just the right coverage.
2. What kind of a grow light is best suited to be used inside a grow tent?
A grow light that does not heat up too much, and provides full-spectrum lighting is what you require when it comes to growing weed indoors. Full-spectrum lighting is very important because you need to provide the right kind of light during both phases of growth, and it would be great if you don’t have to change the lights every time your plants enter the blooming phase from the vegetative phase. About the heat, since tents are enclosed structures, they already trap quite a bit of heat – so try and get a grow light that emits as little heat as possible and operates at cool temperatures.
3. What are some factors that I need to consider before I buy a grow light for my 4×4 grow tent?
Some of the key factors that you need to keep in mind are – What is the kind of lighting spectrum that your grow light provides? Is it a dimmable grow light? Does it support daisy-chaining? Does it provide sufficient lighting for a 4×4 grow tent? These are some basic questions that you need to ask yourself before you get a light. If the answer to these questions is something that suits your needs, then you can totally go ahead for the grow light.
4. Where to buy these grow lights from?
The best place to buy grow lights for a 4×4 grow tent is the Amazon web store. In the 10 products that we have reviewed above, we have also interlinked them to Amazon, so that it is easy for you to make a purchase online. Amazon offers you a very wide selection, as well as some amazing discounts too. However, there’s always the option to go to your nearest gardening or lights/lighting stores and get the lights, but Amazon is always a good option if you have some specific models in mind.
5. How many plants can I grow inside a 4×4 grow tent?
The answer to this question actually rests in the technique that you employ. Under most normal conditions, you can grow somewhere between four to six plants in a 4 x 4 grow tent. However, there are times when you use different methods such as Screen of Green or Topping. In the case of Screen of Green, you actually make the plants wider, so expect that number to fall, and in the case of topping, your plants are taller and not wider, so you can probably grow some more in the same area. But consider 4 to 6 as a safe number.
When it comes to LED grow lights, there are just way too many options in markets out there. With 4×4 grow tents being among the most popular size of grow tents, we thought it was important to put out a best-of list out there. We have tried to provide a review that is as detailed as possible, along with all the pros and cons of the products. However, if you think there’s a specific aspect that you want to know more about, or want us to review a grow light of your choice, do reach out to us over comments or on mail and we shall get it done as soon as we possibly can!
