The 10 Best LED Grow Lights for 4×2 Grow Tents in 2021 [Pictures, Specifications, And More]

What is common between cannabis plants and Superman? They both require the sunlight from the yellow sun to reach peak performance! When you grow your weed indoors, the thing that you will be missing out the most on is the sunlight – which plays a huge role in the growth of your plants. However, as you may already know, there’s an easy solution to this – using LED grow lights.

Over the course of this article, we shall be taking a closer look at LED Grow Lights – and more specifically, those LED grow lights which are the best fit for a 4×2 grow tent. Over the past few articles on our website, we have tried to provide you with an accurate listing for various different tent sizes, and we noticed in the feedback from our readers that they want a comprehensive guide to the best LED lights for 4×2 grow tents as well. This is our attempt at creating just that. 

The list has been curated from Amazon because it makes purchases easier. Furthermore, you don’t even have to step out of your house and the product reaches you in a matter of days. Not only that, you get good discounts which you won’t get in a regular gardening store. Lastly, if you are not satisfied with the product, you can always have it returned via Amazon which is rather quick and easy. 

With that said, let us take a quick look at what we think are some of the best LED lights for 4×2 grow tents:

Best LED Grow Lights for 4×2 Grow Tents in 2021

Before we begin with our list, we must let you know up-front that these grow lights are not ‘ranked’ in any particular order. We have already picked some of the best options that are out there and we have hence placed them in an order that doesn’t necessarily dictate prominence. These are all equally beneficial for your plants growing inside a 4×2 tent. 

1. SPIDER FARMER SF-2000 LED Grow Light

• Makes use of 606 pieces of Samsung’s LM301B diodes 
• Covers 4×2 grow area during the flowering phase 
• Can be dimmed 1-100%  

Spider Farmer’s grow lights are rather popular with growers, not just because they provide a high quality lighting, but also because they operate at very low costs. This grow light provides the perfect coverage for a 4×2 grow tent, and has been preferred by thousands of users all over the world who are very happy with the kind of performance that they are getting out of it. 

The light makes use of Samsung’s high-quality LM301B diodes, along with a MeanWell driver. There area total of 606 pieces of LEDs that are used in this grow light, which make it quite bright! Another interesting thing about the Spider Farmer 2000 is the way that they have arranged the lights. Unlike other grow lights where you’d see an even spread, the LEDs are arranged here in a way that they are light in the middle and dense at the edges which gives it a bigger spread and also ensures a better PPFD (up to 1518 umol per square meter, from 12”). This is a full-spectrum grow light which comes along with 2 IR diodes included in it. 

This grow light also comes with support for two more features that are often demanded – daisy chaining as well as dimmability. You can hook up to three devices to each other as that is the standard accepted safe limit. Besides that, you can dim each grow light individually depending on the needs of your plants. 

Lastly, one more thing that the growers appreciate about the SF-2000 from Spider Farmer, and one of the reasons as to why it is truly considered the best LED light for 4×2 grow tents is that it operates on a fanless mode. However, the light operates at pretty low temperatures and there’s minimal heat generated from it, which makes it completely safe for the use of your plants. 

2. Mars Hydro SP3000 LED Grow Lights

• Makes use of Samsung LM301B diodes 
• Provides flowering coverage of 4×2 and vegetative coverage of 5×2 
• Consumes 300W of power  

Another really popular name in the markets when it comes to grow lights for indoor growers, Mars Hydro rarely disappoints! This grow light is just the perfect option for growers who trust the brand to get their hands on, particularly if they are looking for a grow tent that measures 4×2. This is a light that can be used by home-based growers as well as professional growers who grow their weed in large-scale operations. 

The SP3000 grow light from Mars Hydro features the same Samsung LM301B diodes which we have seen in the Spider Farmer light above. These are authentic and Samsung-approved diodes, unlike many cheap imitations that we tend to see in the grow light markets. The grow light also makes use of the same MeanWell driver so the quality of lighting that you get from both these grow lights is identical. However, given that the lights are arranged differently in both – with SF2000 having a square shape and Mars Hydro SP3000 having a rectangular shape, the way the light spreads is different in both these grow lights. 

This grow light consumes nearly 300W of power from the wall socket but delivers about 3000W of total output. The kind of lighting that you get here is ideal for a 4×2 grow tent, because the vegetative coverage is about 5×2 ft, and the flowering coverage is 4×2 – exactly the amount a plant needs. Sometimes people make the mistake of going for a light that gives them a spread of 4×2 in the vegetative stage – that means the coverage during the flowering phase is definitely going to be lower. However, this is not the case with the SP3000.

This grow light comes with a dimmable knob too, which would allow you to adjust the brightness just the way nature would have it, if the plant were to grow outdoors. The light operates without a fan but does not generate too much heat. This is also a great grow light for people who are planning on growing hydroponic weed. All in all, a pretty good grow light for all your 4×2 grow tent needs. 

3. VIPARSPECTRA P2000 LED Grow Light

• Makes use of Samsung’s LM281B+ diodes
• Provides a flowering coverage of 4×2 and a vegetative coverage of 4×3 
• Full-spectrum grow light  

There’s perhaps no other brand as popular as Viparspectra when it comes to this space. An absolute dominating force in the world of grow lights, Viparpsectra’s P2000 is perhaps the single greatest grow light equipment when it comes to covering tents that measure up to 4×2 ft in size. One of the most trusted brands out there, the grow light makes use of Samsung LEDs, but not the Samsung LM301B’s that we’ve seen in the two above, it makes use of the high PAR Samsung LM281B+ lights.

The grow light is known for its high PAR output, as well as for the deeper penetration rates that it offers. This is a full-spectrum LED light from Viparspectra, and it provides 660nm of red light, IR, 3000K and 5000K of the white light spectrum. This makes it very well suited for the flowering as well as the vegetative phases. The light is extremely similar to the natural light of the sun, and this provides great benefit to the plants growing indoors, which do not have access to that light. The light also comes with a dimmer knob which allows you to adjust the intensity of the lighting based on the kind of experience you want to provide your plants. 

Another aspect about which Viparspectra likes to market this product quite a bit on is that this is a ‘sleep friendly’ product. If you are from an older generation of growers, you might have seen those bulky LED grow lights where fans were used to dissipate heat. Those fans generated a lot of noise and using multiple such grow lights could be quite loud. This grow light, however, works on a fanless design and ensures you can sleep in peace without any of that noise!

The grow light offers a vegetative coverage of 4×3 ft and a flowering coverage of 4×2 ft, both of these are figures that suit the growers pretty well, especially if they are growing in a 4×2 grow tent. This grow light can actually be compared to a traditional 400W Metal Halide/HPS light, but it consumes only 200W in providing the same amount of output. Lastly, this is a long-lasting grow light from Viparspectra, and you also get a 3-year warranty along with that. 

4. BLOOM PLUS LED Grow Lights, BP 2500W

• Consumes 250W of power from the wall socket 
• Provides a 3×5 vegetative coverage and a 4×2 flowering coverage 
• Full spectrum grow light  

The BP2500W LED grow light is one of the most popular and among the highest-rated LED grow lights on Amazon if you are specifically looking for something for a 4×2 grow tent. The grow light has been used by hundreds of thousands of growers all over the world and is one of Bloom Plus’s best selling products. 

Coming to the specifics, this grow light too relies on Samsung LEDs, as it makes use of the Samsung 2835 diodes. There are 646 pieces of LEDs that are used here, and it provides a pretty bright output which helps you get the best possible results when it comes to growing plants indoors. Brighter lights also help you get a better yield per square foot, which is always something that growers appreciate. 

The light operates at a high energy efficiency of 2.7 umol/J, and is one of the most energy efficient grow lights, consuming only 250W and providing an output equivalent of 500W. BP2500 provides the growers with a vegetative coverage of 3x5ft, and a flowering coverage of 2x4ft, which is perfect (and is actually a little more than what you really require) for a 4×2 grow tent. This grow light is also dimmable, which is another plus point as you can adjust the lighting based on the needs of your plants. 

Besides this, the grow light also comes with a full-spectrum lighting setup, and ensures that your plants get the right kind of lighting across the different phases of growth. The white and blue lights can help them power through the vegetative phase and the red lights will help your plants boost their flower production during the flowering phase of their life cycle. 

Lastly, these grow lights are designed in a way that they emit very little heat, and hence they do not need a fan to cool them down! This is a big benefit. First, it helps keep the grow lights lightweight and slim. Secondly, eliminating the fan means you are eliminating the noise that comes from the fans! This can be quite a relief for people who tend to grow weed at a large scale. 

5. VIPARSPECTRA Latest XS2000 LED Grow Light

• Makes use of Samsung LM301B diodes 
• Provides a 4×3 coverage during vegetative phase and a 4×2 during flowering 
• Warranty period of three years 

Armed with the same Samsung LM301B diodes that you see in most of these lights on our list, this is perhaps the most recent grow light to come from the house of Viparspectra. A 2021 release, this grow light provides the growers not only with a very bright lighting solution, but also with one of the best heat dissipation mechanisms. Viparspectra’s experience in this field is unparalleled and the XS2000 is a ‘shining’ example of just how good they are when it comes to manufacturing grow lights. 

This is a full-spectrum grow light from Viparspectra, giving the growers a combination of 3000K warm white, 5000K white, 660nm deep red, and 730nm IR lights. This means that your plants get a variety of lights combined to give them an experience which is as close to natural sunlight as you can recreate inside a grow tent. The red and IR lights are great for the blooming phase, while the white lights are helpful during the vegetative phase of growth. 

A dimmer is also provided with this grow light, which helps the growers increase or decrease the brightness based on the needs of their plants. In the past, having a grow light with dimmers seemed to be the exception, however, of late it has become a norm. One thing that this grow light does not come with is fans – and users are really thankful for that. This gives it two advantages – that of being thinner and lighter, and therefore easy to hang, and secondly, that of being silent. Back in the day, some grow lights with fans would be so loud they won’t let the growers sleep! With the XS2000, however, that does not seem to be a problem. 

The grow light provides a 4×3 coverage when it comes to the vegetative phase and a 4×2 coverage during the flowering phase when you lower it. This makes it an ideal grow light for a 4×2 grow tent. Lastly, when you buy this grow light, you get a three-year warranty period, as well as customer-friendly support. Viparspectra has really worked hard on their after-sales support over the past few years and it is pretty evident with the kind of service you now get with them!

6. Phlizon PL-1000 Plant LED Grow Light

• Makes use of Samsung LM301B diodes 
• Provides full-spectrum lighting 
• 3-year warranty period  

When it comes to low-cost or cost-effective lighting solutions, perhaps there’s no brand out there which is as popular as Phlizon. The PL1000 comes in at a price point of under $100 and is one of the best options if you are looking for a cheap 4×2 LED grow light that doesn’t burn a hole into your wallet. This grow light also comes with a free thermometer which also doubles up as a hygrometer, which is an added benefit. 

Samsung is really taking over the grow light markets! Even the PL1000 from Phlizon makes use of Samsung’s LM301B diodes. There are 238 pieces of these diodes used here. This basically means that when it comes to the lighting experience and the quality of diodes used, pretty much every grow light on this list is at par with each other. The true difference lies on how much of the light penetrates into the plants, the amount of electricity they consume and in the way they dissipate heat.

Talking of heat dissipation, the Phlizon PL1000 comes without a fan – as the diodes operate at a very low temperature. Upon normal usage, the grow light generates very little heat and you don’t even need a heat sink here, which is why it has been completely removed. This is a full-spectrum grow light that provides 112pcs 3000K leds ,96pcs 6000K leds, 30pcs 660nm red leds. The light also comes with a dimmer switch and you can adjust the brightness levels based on your needs.

This grow light also supports daisy chaining, which means you can hook multiple such grow lights on to each other with only one of them being connected to the main power source. Phlizon also touts their manufacturing process quite a bit and emphasizes on the fact that their Research & Development team and light testers work really hard to come out with a product that is of top quality. There’s a three-year warranty and a 30-day money-back guarantee on the grow light. 

7. SPIDER FARMER SF-600 LED Grow Light

• Makes use of OSRAM diodes 
• Full-spectrum grow light 
• 50,000 hours of lifetime performance   

Spider Farmer’s SF600 is one of the best grow lights for your plants in their early phase, and it can also be a very good fit for people who are into growing plants hydroponically. This grow light provides you with a very low energy consumption, and is particularly appreciated for its low power draw – only 72 Watts from the power socket. 

SF600 comes out into the markets with 384 pieces of OSRAM diodes, which provide a total output of about 5000 Lumens, which is pretty good for growing plants indoors. The light also has reflectors on the sides, which ensure that the spread is even and all your plants in a 2×4 area are covered well. There’s a 120-degree beam angle which makes sure a larger area is covered. 

You also get a full spectrum lighting experience here, as the grow light consists of 660-665nm(Red), 730-740nm(IR), 2800K-3000K(warm white), and 4800-5000K(Blue) lights. A combined output of these lights provides a near-natural, sun-like lighting experience to the plants that you are growing. This is as close as you can get to recreating sunlight indoors. Having a full-spectrum lighting setup can also boost the chlorophyll production of your plants. 

Another thing about these Spider Farmer grow lights is that they are very easy to set up and install. It is a very simple plug and play setup as you don’t have to assemble anything here! There are no ballasts and fixtures involved too, like the old-school lighting setups. If you are an indoor grower, this is as easy as it gets for you. Lastly, one final thing about the SF600 is that it provides you a 50,000 hour lifetime, and offers a 3-year warranty period. 

8. MAXSISUN MF2000 Grow Light, 230 Watt LED Grow Light

• Remote-controlled grow light 
• Covers a flowering space of 4x2ft 
• Full-spectrum lighting   

Anyone who has been growing cannabis indoors for a while is likely to have come across the Maxisun brand. While it doesn’t rank among the Viparspectras of the world, it is still one of the better brands out there, and one that you might want to consider if you are planning on buying a grow light for your 4×2 grow tent. This is the Maxisun MF2000 grow light, a product that thousands of growers all over the world have trusted. It is one of the best-rated Maxisun grow lights on Amazon.

The MF2000 comes out into the markets with a set of 700 Samsung-made diodes. This is a full-spectrum grow light which consists of 3500K warm white, 5000K neutral white, a few 660nm deep red, and 730nm lights. This makes sure that no matter what phase of growth your plant is in, you are getting good quality lights which are well-suited for its growth at all times! 

One of the most unique features about this grow light is that it can be controlled via a remote. No need to actually tune things physically using knobs or switches, you can use a remote control to adjust your lighting. You can turn the light on and off using the remote, as well as control how bright or how dim it is going to be. If you have daisy-chained your lights, you can also make use of the remote to set group-based brightness patterns. This is truly the highlight of this grow light. 

The light comes with reflectors on the side which allows it to get the maximum coverage possible. The aluminum reflectors used here ensure that the light doesn’t just bounce off, but is actually put to use. On the top of the grow light, there’s a 15mm heat sink to dissipate the heat. With a lot of grow lights, light-loss is a real problem. Maxisun, however, has taken care of that. The MF2000 comes out into the markets with a three-year warranty, and a 90-day money-back guarantee, in case you are not satisfied with how it performs. 

9. FREELICHT FL-2000 LED Grow Light

• Makes use of Cree and OSRAM LED chips 
• Full-spectrum lighting 
• Dimmable grow light  

Here’s a lesser-known brand, Freelicht, one that hasn’t really been around the markets for a long time. The FL2000 LED grow light gives the users a combination of good specs, as well as a durable framework. On the outset, it has got an attractive black-and-orange body, one which many users would find rather interesting. Instead of going for the typical Samsung LEDs, Freelicht has chosen to use LED chips manufactured by CREE & OSRAM.

The grow light promises to offer 30% higher yields than most of its competitors out there. The light consumes only 200W from the wall socket and operates at an energy efficiency of 2.9 umol/J. This is a full-spectrum grow light that comes with warm lights(3000K),blue lights(5000K), IR lights(730nm), and red lights(660nm) – giving your plants a complete growth experience, as blue lights are useful during the early phases and red lights are important during the flowering phase.

The light is dimmable, but has an interesting feature here – it goes down to as low as 5%, but doesn’t stop at 100% at the upper end. It goes up to 110%. The extra 10%, the company says, is useful for the plants during the flowering phase where extra light can help them boost their output and help them obtain bigger flowers. The grow light also supports daisy chaining and up to four such grow lights can be hooked on to each other. 

This is one for those who like to experiment, for those who like to take the plunge, and for those who like to be the first ones to try out a new brand. It has got some good ratings and seems to be a pretty promising grow light for 4×2 grow tents. This is the 200W variant, but if you have different needs, you can also check out their 100W and 400W variants, also available on the same Amazon page! Lastly, another thing that stand out about this grow light is the fact that it offers the longest warranty period we have ever seen on a grow light – up to a period of five years!

10. MIEEMCLUX C1000 LED Grow Light

• Consumes 100W of power 
• Supports dimmable lights
• Full-spectrum grow light  

Yet another name which isn’t really one that you will hear a lot in the markets, but one that is an up and coming brand for sure, MIEEMCLUX makes some of the best and most modern-looking LED grow lights out there, and we’ll be honest, this is about a foot larger than what you’d actually need as it is a 4×3 grow light instead of a 4×2 grow light, but having a little more never hurts! 

This grow light comes with a rather wide footprint, especially for a series-1000 light. There are 324 LEDs on the board, and the grow light offers an output of about 250 to 300 Watts when you compare it with a traditional HPS or MH grow light. However, the actual power draw is only 100W. This saves you a lot of power and gives you quite the advantage if you were planning to grow in bulk. 

There’s a dimmer knob on this grow light which allows you to change the brightness from 0 to 100%. The grow light offers a full white spectrum of growth which is as near to the natural light of the sun as it could possibly be. The light operates without a fan, as it generates very low heat! In fact, since it does not have a fan, it also eliminates another major problem which growers tend to face often – that of the sound that grow lights can generate if they are using a fan to lower the temperatures. 

Lastly, the MIEEMCLUX C1000 LED grow light offers you a three-year warranty period, which is pretty good, as well as a 90-day money-back guarantee if you are not satisfied with the performance of the product. The customer support is also pretty good here and they ensure quick turnaround times. If you are looking forward to try out a new brand, we would strongly suggest you to check out this grow light! 

Frequently Asked Questions About 4×2 Grow Lights

Here are the answers to some of the most common and frequently asked questions about grow lights for 4×2 grow tents. Do go through these as these answers will help you get a better perspective about these grow lights. 

1. Can I buy a grow light that covers a grow area less than 4×2?

Ideally you should buy grow lights that provide an exact amount of coverage. This is because getting a light with a smaller coverage would result in the plants that are further away from the center getting lesser coverage. However, you can use two 2×1 grow lights to get a proper scatter over the area. However, using a single grow light with a proper 4×2 coverage would be best suited for your plants. 

2. Can I buy a grow light that covers a grow area of more than 4×2?

Getting a grow light that is somewhat larger than the actual coverage shouldn’t hurt. For instance you can get a 4×3 or a 4×4 grow light. However, getting a grow light that covers 5×5 or larger would actually be counterproductive as that would be too much light for your plants. When you provide more light to your plants than is needed, you are stressing them out and they will have to produce enzymes beyond their capacity and need. This leads to plants getting stressed and in an unusual growth. Similarly, if your light is too intense, there might be a ‘light burn’ that can occur. Hence, it is recommended only to get a light that is 4×2 to 4×4. 

3. What kind of lights are the best suited for these grow tents?

LED grow lights are generally best suited when growing cannabis plants indoors, and particularly in grow tents. This is because most of the modern-day LED grow lights operate at low temperatures and do not heat up. They do not cause heat burns or light burns to plants if used correctly, while also consuming very little electricity when compared to HID lights or other older forms of lighting. These lights also provide full-spectrum lighting which means your plants are covered for both, the vegetative, as well as the flowering phase and you, don’t have to change lights every time the phase changes.

4. How to make sure that my grow lights last a long time?

To ensure that your grow lights last you a long time, make sure you’re switching them off from time to time, and also ensure that you are keeping them away from the three things that can cause them to go bad – heat, water and dust. Generally in a grow room, there is no dust and heat is often controlled and reduced to suit the plants. However, considering that there’s often a lot of water involved when it comes to feeding your plants and helping them grow, make sure that you stay careful and do not accidentally spill some on the lights. 

5. How to ensure that grow lights don’t damage the plants?

To make sure that your plants aren’t getting the much-dreaded ‘light burn’, make sure you are keeping your lights at a safe distance from them. This is generally observed in the top regions of the plants. Similarly, if you begin to see any signs of stress on the plants, such as unusual buds growing, make sure that you move your light a little further up to reduce the impact. Also make sure you reduce lighting hours as the plant grows. A flowering plant might do well with just 10 hours of light but a plantling at its young stages might need up to 22 hours of light. 

6. Where to buy the best LED lights for 4×2 grow tents?

As mentioned earlier, Amazon is perhaps the best place to get hold of these grow lights, because it helps you get better discounts and easy returns, as well as doorstep delivery. However, you can always walk into your neighbouring gardening store and get them. Grow lights are pretty common and can be found in almost any place that sells gardening equipment. However, Amazon gives you the option to go through a much larger number of options to choose from, which may not be available in the local stores nearby.
