1. Phlizon 2020 Pro Series LED Grow Light – Best Value For Money

The Phlizon 2020 Pro series LED grow light is the best bang for your buck. 

Somewhere in the mid-price range, this grow light boasts incredible features, ideal for those who want a high-quality LED grow light but don’t want to spend too much on it. 

The outstanding feature of this model is certainly the large irradiation area, ideal for a 4×4 grow tent. This is partly due to the SMD lamp beads, but also because of the special design that features 720pcs led beams.

If you need a full-cycle lighting solution for all growing environments, the Phlizon 2020 Pro series grow light is for you.

It provides high light intensity, less light decay, better lumens, and PAR values. At 2.8 µmol/J (micromole per Joule), these lights are very energy-efficient. 

Although the grow light is pretty intense, you can adjust the intensity according to your plants’ needs.

The dimmer works perfectly and the light ideally mimics natural lights as it’s made of 3000K LEDs, 6000K LEDs, and 660 nm red LEDs.

One thing we really liked about the Phlizon 2020 Pro series grow lights is the high water resistance.

The waterproof power supply is installed outside of the lights so it’s super convenient to replace if necessary. 

The light board features sealing technology to ensure all the LED bulbs are waterproof. 

What’s more, this model is designed to be fanless, so you can be sure there won’t be any excessive noise disrupting the plants and harmony in your 4×4 grow tent. 

The fact that it’s waterproof and noiseless makes the Phlizon 2020 Pro grow light a perfect candidate for your grow tent, and the reasonable price is just icing on the cake. 

However, there have been a few reviews that complain about the lights getting too hot which isn’t great news for your plants. Also, some have complained about the LED light not having a long life span. 


– Best value for money
– Big irradiation area, perfect for a 4×4 grow tent

2. MARS HYDRO TSW Led Grow Light – Runner Up


  • Simple to install and use
  • Easy dimming
  • Saves up to 50% energy
  • You get a 30% higher yield
  • Completely silent
  • Long lifespan
  • Full-spectrum light


  • Not affordable
  • Although unlikely, the LED lights may start to flicker and/or buzz

Whether you’re a long-time plant grower or just a beginner, you should look into the Mars Hydro TSW LED grow light.

It is convenient to install, easy to use, and comes with cool features – perfect for amateurs and professionals.

mars hydro tsw 2000 led grow light 01

For instance, Mars Hydro TSW LED lights feature easy dimming and daisy chain design, 15 connected multi-lights, and a convenient main light controller. 

LED lights are all about energy efficiency and we really liked how Mars Hydro light performs in this area.

Namely, Mars Hydro LED grow light consumes only 300W with 684 LEDs. This means they will save up to 50% more energy than other grow lights. 

In addition to this, the new SMD LED technology used to make Mars Hydro lights provides the highest PAR/LUMEN output. As a result, you get a 30% higher yield compared to the old blurple and cob LED lights.

When growing plants in a grow tent, you need lights that will mimic natural light conditions as much as possible. And that’s what you get with Mars Hydro light. 

These grow lights are engineered to provide improved growing performance for plants at all growth stages.

The uniform and wide-beam light distribution combined with 3000K, 5000K, and IR lights make the closest thing to the natural light spectrum.  

Let’s not forget the importance of the fanless design – the Mars Hydro lights work in complete silence, providing you and your plants with the much necessary quietude. 

Longevity is one more great thing about Mars Hydro lights. The manufacturer promises more than 50,000 hours lifespan (almost 6 years), which is pretty admirable.

Are there any downsides to these seemingly good grow lights? 

Well, yes.

Sadly, some Mars Hydro customer reviews mention flickering of the lights in the grow tent after only one month of use.

A few say that, while flickering, the lights started to buzz annoyingly. We haven’t had a similar experience, but it’s worth mentioning nevertheless in case you’re considering adding these lights to your grow tent. 

3. MAXSISUN LED PB4000 Grow Lights – Premium Choice


  • Full-cycle plant growth lighting solution
  • Extremely energy-efficient
  • Excellent life span
  • Strong construction
  • lifespan 100,000 hours


  • Not budget-friendly
  • Issues with the dimming feature

The MAXSISUN LED grow light is a true premium choice.

If you’re not on a limited budget and you don’t mind spending a few extra bucks on LED grow light for your plants, we highly recommend you invest in a top-tier model such as this one. 

As the manufacturer likes to say, these LED lights are “born for harvest.”

What they mean is that this model is a top-notch commercial-grade horticulture lighting solution.

maxsisun pb4000 grow lights 01

It’s created to support plant growth in a grow tent from seeds to harvest thanks to the full spectrum tailoring and design. 

Maxsisun LED grow light also has a great level of efficiency – 1.93 μmol/J.

However, although most similar lights consume 300W, this one actually pulls 400W from the wall. Still, it manages to achieve better results than 800W HID with 50% less power consumption.

You’ll be glad you’ve coughed up the money for Maxsisun once you see your power bill.

Jokes aside, these LED grow lights really are a great choice for a 4×4 grow tent.

Besides the higher photon efficiency, the PB4000 series also features a silent design

This series also boasts heavy-duty, solid construction – the LEDs are protected by glue coating (the water-resistant IP65), and the aluminum heat sink is big and, at 5mm, it’s pretty thick. All this means the PB4000 is built to last.  

One feature that sets these LED lights apart from the competition is the long lifespan. That’s right – you can enjoy the PB4000 for more than 100,000 hours!

On the other hand, one huge problem of Maxsisun LED grow light concerns the dimmable effects.

As it turns out, while advertised as dimmable, surprisingly many customer reviews complain they aren’t; at least not to the industry standard 0-10/1-10v circuit.

If you can look past this flaw, we believe your grow tent could benefit a lot from the Maxsisun LED PB4000 series. 

4. Bloom Plus LED Grow Light – Among The Best


  • Energy efficient
  • Optimal full spectrum lighting
  • Silent fanless design
  • Dimmable lights


  • Kind of expensive
  • Can be too bright for a 4×4 tent
  • Customer complaints about the longevity of the bulbs

Although on the pricier side, the Bloom Plus LED grow light is worth it. 

These lights utilize the newest high-yield LED tech thanks to which they manage to achieve a high energy efficiency of 2.7 μmol/J. Furthermore, they consume only 300W of power, which is impressive. 

If you need dimmable LED light for optimal full-spectrum lighting in your grow tent, Bloom Plus is for you.

Plant growers will find the IR light particularly useful as it speeds up bloom time. For any other plants, the powerful blue light that helps plants grow faster will do wonders. 

Another advantage of Bloom Plus LED grow light is that they feature a fanless design, and you know what this means – silent growth life

bloom plus led grow light

We can’t fail to mention the Samsung LED chips and the LED board that’s passively cooled by a large, thick aluminum heat sink. The aluminum material is fast-dissipating so it helps to reduce the light lost in the walls and walkways. 

This way, the light intensity is increased by 20%, and your plants get more energy without getting burned. Pretty efficient, huh? 

While it has some great features, this model is not without flaws. It’s important to mention that a few customers have complained about the light intensity in the tent.

Namely, for some, these lights were too bright after all. 

A couple of clients even said that a few bulbs burned out after only a week, so longevity may not be their strongest suit.

Also, a common complaint was about unresponsive customer support. 

Now, the bad reviews are only a small fraction of plenty of positive ones, so who’s to say? All in all, Bloom Plus LED lights deserve a passing grade!

5. KingLED 1500w LED Grow Light – Budget-Friendly Solution


  • Affordable price
  • Bloom and veg switch
  • Effective cooling system
  • Saves energy
  • Long-lasting bulbs
  • Full-spectrum lighting


  • It features cooling fans that make some noise

Need budget-friendly LED grow lights for a 4×4 grow tent? You should check out the KingLED grow light. 

This model includes almost identical features to many high-end ones, like the upgraded SMD LEDs, reflector technology, and full-spectrum lighting design. 

Not only are the KingLED lights reasonably priced, but they’re also cost-effective in other ways. 

For instance, they’ll help reduce your electric bill. The SMD LEDs and the reflector tech mentioned above actually consume only 195W.

It saves a lot of energy (and money) without compromising the light intensity in your tent. 

This grow light also features veg and bloom switches. You can turn on the veg switch, the bloom switch, or both depending on the growth stage of your plants.

We also appreciated the efficient cooling system of this model.

It features multiple high-speed cooling fans that, mixed with aluminum radiators, enable the light to work at a pretty low temperature – between 50°F and 60°F. You can rest assured knowing your plants won’t be burned. 

Now, we know what you’re thinking – these lights have cooling fans? Doesn’t that make excessive noise? 

It doesn’t really. The cooling fans are actually mute. However, it may not be as quiet as it would with other fanless lights, so if that’s a crucial feature for you, we suggest you skip this one. 

If you don’t mind the slight noise, you’ll like the fact these lights provide full-spectrum lighting from 380 nm to 780 nm, including UV and IR.

This means your plants will get a pretty good mockup of natural lights in all growth stages.

Oh, and one more thing – the lifespan of KingLED grow light is more than 100,000 hours. Not bad for such affordable lights. 

6. Abriselux A1500 LED Grow Light – Good Penny-Worth


  • Budget-friendly price
  • Additional dimmer knob for efficient dimming
  • Energy-saving solution
  • Natural full light spectrum


  • Lifespan is questionable

Another quite affordable LED grow light is this Abriselux A1500. For a relatively cheap price, you get some nice features. 

For example, the large size board comes in handy for 4×4 grow tents. Not only does this increase your lighting coverage, but also makes your planting more efficient.

The large aluminum board works to dissipate heat and maintains the working temperature under 131°F at all times. 

abriselux a1500 led grow light

The dimmer is another great feature of the Abriselux A1500. They added an extra dimmer knob in the control system to allow you to manipulate the light intensity better.

You can turn it up anywhere from 0% to 100%. This is ideal as it makes it possible to provide your plants with the necessary light at any time from seeds to harvest. 

With 2.6 μmol/J, the Abriselux A1500 lights are very energy efficient. They manage to deliver a powerful light output for your plants without running your electric bill through the roof – the energy consumption is only 150W. 

Your plants will love the full spectrum light they’ll get from these grow lights. A combo of SMD diodes in a multi-spectrum layout creates a complete natural full white spectrum for all growth stages. 

The lights consist of 5000K white, 3000K warm white, 660nm deep red, and 730nm IR light. The last one is super useful during veg and bloom as it accelerates bloom time and enhances yields for the ultimate harvest. 

Abriselux A1500 LED grow light’s lifespan is not half bad either. The manufacturer claims they can live up to 100,000 hours and more.

However, some users complained this is not entirely true. When you think about it, even half of that is pretty long, so anything over 50,000 is considered great. 

7. SUNRAISE QB3000 LED Grow Light – Great Lighting Solution


  • Covers a large area
  • Fanless design
  • Saves a lot of energy
  • Useful dimmer knob


  • A tad expensive
  • Not the longest lifespan

Sunraise is a company dedicated to spectral science and lighting solution, so they didn’t disappoint with the QB3000 LED light for a 4×4 grow tent. 

With its unique design, the QB3000 stands out among others. Its large size and big footprint make it even more special – it’s an ideal solution for wide-area light coverage. 

The design features six aluminum heat sinks that dissipate the heat and keep the temperature at an optimal level for your plants.

When you adjust the height accordingly, your plants will benefit from QB3000 at any growth stage.

Plus, by adjusting the light intensity, you can rest assured the plants are getting just the right amount of light – neither too much, nor too little. The dimmer knob allows you to set the intensity at the desired level from 0% to 100%.

Another great feature is the absence of fans. The absolute silence in grow tents is appreciated, and that’s exactly what you can expect from this model. 

The lack of natural light is not something you need to worry about.

The Sunraise QB3000 consists of 972pcs SMD in total – 6000K, 3000K, 660nm red, and 740nm IR lights that, mixed together, create ideal light for your plant life. 

We have to note that the energy consumption of this LED grow light is 300W, which is significantly less compared to the traditional 600W HPS/MH, so in the end, you do save up a lot of energy. 

While most similar LED grow lights boast 100,000 hours lifespan, this one’s life expectancy is around 50,000 or so hours.

Although it’s not as much as perhaps you’d wish, it’s not that bad when you consider other useful features. 

All in all, albeit on the pricier side, Sunraise QB3000 doesn’t have any significant flaws so we’d say you’re investing your money wisely.

Have you wondered what are the exact benefits you get from high-quality LED lights? Check out the list below. 

You’re saving energy

We’re sure this isn’t groundbreaking news to you – LED light bulbs are the most energy-efficient of them all! 

Unlike the power-consuming incandescent bulbs that use heating to give electricity, all LED bulbs need to light is an electric current. This way, the energy consumption is minute.   

You’re saving money too

Just think about it – with energy-efficient LED light bulbs, your electric bill won’t go through the roof anymore. And let’s face it, any money-saving opportunity is always welcome!

LED light bulbs last longer

Generally speaking, different light bulbs have different lifespans.

Although LED light bulbs cost a tad more than others, you get your money’s worth considering they also last way longer (up to five times actually!) than any other bulbs.

This is largely due to the fact that LED bulbs aren’t affected by constant switching on and off that makes other bulbs short circuit and burn the light filament. 

A variety of options to choose from

The LED light comes in a wide range of shapes and colors so you can choose according to your preference.

Small light bulbs are real space-savers

Does size really matter? Not when it comes to LED light bulbs! 

That’s the great thing about LED – even the smallest bulbs can produce maximum light. And we don’t have to tell you how handy small bulbs are when space consumption is a must.

How To Choose The Best LED Grow Lights For A 4×4 Grow Tent

led lights

Since LED grow lights can be expensive, you shouldn’t buy them willy-nilly. There are things to consider if you want to make a smart purchase, such as: 


One of the biggest benefits of LED light products over others is their burning time. Some brands have managed to produce LED grow light with a lifespan of 100,000 hours or so, which is admirable, to say the least. 

However, don’t expect all LED lights to have such a long lifespan. Around 50,000 or less is what you should expect, and anything over it is a huge plus.

Still, it’s a lot more compared to others and you do get the best value for your money. 

Generally speaking, the best grow LED lights are long-lasting, but make sure to check the lifespan of the light you choose for your 4×4 tent so you know what to expect. 

Shape and size

A 4×4 feet grow tent is not a very large grow space so you have to take into account the size of the LED grow light you want to purchase.

You have to match the size of the light to the size of your grow tent to ensure the heat balance and that your plants receive the heat evenly during each growth stage. 

While the shape is not crucial, you can choose between different types according to your preferences.

The great thing about LED grow light is that they come in different shapes and sizes, so be sure you’re getting the ones that suit your grow tent and your plants the best.


Every LED grow light features info about energy efficiency. Usually, you’ll see it expressed in μmol/J or micromole per Joule.

This measurement determines how efficiently a light converts electrons into photons. The higher the value, the more efficient the light. 

LED lights are generally highly efficient.

We don’t have to tell you the significance of energy-saving capabilities – if you have a grow tent (or tents), you know that inefficient lights can run up your electric bill in the blink of an eye. 


Most of the best LED grow lights for 4×4 feet grow tent are not complicated to install.

The ones that made our list are all fairly easy to install and use, so you ought to be able to do it yourself without any issues. 

If, however, it comes to that, they come with detailed instructions that can help you out.

Worst case scenario – you can call a professional to help you install the light properly. 


When choosing the best LED grow light, we can’t dismiss the price points, especially since some models cost twice as much as others.

That being said, we’ve made sure to include excellent choices from both sides of the price spectrum, so you can choose between high-end items and budget-friendly options. 

On average, an LED grow light goes for $200. You can find options under this amount, and there are plenty that cost a lot more.

However, most of the really expensive ones are commercial-grade grow lights used in grow tents much larger than 4×4. 

The bottom line is – think about your budget and how much you can (and want) to cough up for LED grow light, and start from there.

Sure, the expensive ones may have better features, but don’t dismiss the cheaper ones so easily, they might surprise you! 

Dimming abilities

Most products and brands mentioned today have amazing dimming options.

It’s vital to consider the dimming capabilities of the best LED light for 4×4 grow tent. In other words, you have to think about the light intensity.

Different growth stage requires different light intensity, so proper dimming options are crucial.

Power consumption

Most LED grow lights consume around 300W in a grow tent. Some use less energy, some use more, so don’t forget to check the exact power consumption before purchasing.

Heat sinks

A LED grow light for a 4×4 grow tent should feature a sturdy, ergonomic design with aluminum heat sinks that dissipate heat in grow tents.

This is important for any growth stage so your grow tent doesn’t get too hot and burn your plants.

Full-spectrum lighting

Full-spectrum lighting is a vital part of LED grow light products.

Growers know the importance of adequate light in every stage of plant growth, and the only way you can achieve that in grow tents is with a full light spectrum.
