But there is no doubt that finding the best led grow lights will significantly improve your work.

Whether you’re replacing an older light system or you’re only just now starting a grow project, you may be overwhelmed by the number of choices you’ll be confronted with when you purchase your first LED grow lights.

And finding the best grow lights as we know is essential.

While all LED lights are superior to competing lights, there are a few that stand out from the rest due to their superior features and value.

Without beating around the bush too much, let’s jump right into it…

Complete Beginner’s Guide to LED Lights

 Grow Lights for Growing Plan

LED grow lights are a wise choice, provided you’re using them correctly and you understand how they work.

A little research and some math are necessary to determine how many lights you need, where you’ll need to put them, what the lights are doing, and how to use them effectively.

How the Light Works

Certain plants grow better during certain seasons. This is because, at different times of the year, the sun is providing them with different things.

LED grow lights work by replicating this process as close to nature as possible within their indoor environment.

Most LED lights are full spectrum.

This means you’re getting blue light, as well as red lights. These lights are at opposite sides of the spectrum of the light provided by the sun, and having these lights allows you to better duplicate the sun’s process.

In order to get the most out of your LED light, you need to find one that provides this spectrum.

Since most do, this isn’t at all a difficult process.

While it all just seems like colors, your plants are actually eating these colors, and they’re an important part of their diet.

Buying separate red and blue lights won’t work as well.

Your plants need the optimum amount of both kinds of light during different stages. Most LED grow lights are dual-stage and will offer you the ability to easily flip a switch depending on what stage your plants are in.

You won’t need to change anything throughout the process outside of flipping that switch. A thorough blend of lights is ideal to provide your plants with the balance they require.

Giving your plants LED light actually nourishes them.

Plants grown under LED light will actually utilize fewer nutrients because they’re not relying on them as heavily to grow.

Plants grown without a spectrum light have to overcompensate for what they’re not getting, and this affects their nutritional needs.

Plants under other lights are hungrier because they require more energy to grow.

Light Cycles and Growth Cycles

For your plants to bud as best as possible, you need to pay careful attention to how much light they’re getting during certain parts of their development, as well as how much darkness they’re getting.

You’re not only trying to replicate natural day, but also natural night.

Seedlings and clones require the most amount of light to get started

Sometimes, 24 hours of light is completely suitable for these stages of the plant.

The important thing is that you’re providing no more than six hours of darkness for these plants that are really depending on the light to get strong.

Plants in the vegetative stage will require 18 hours of light to reach their fullest potential.

The six hours of darkness they receive is vital in giving them a break. This darkness is like their sleep, and it’s helping them store their energy appropriately.

Overtaxing your plants can cause premature death before you even reach the flowering stage.

It’s very important you let them have their rest.

During the flowering stage, energy conservation is the most important. It takes a lot of your plant to produce a healthy bud, and they’ll need to rest for an amount of time equal to their growth.

A good rule here is to divide the light cycle directly in half. One hour of rest for every hour of growth is crucial, so 12 light hours and 12 dark hours will give you the best result.

These light cycles are best handled by placing your lights on a timer.

If you’re sleeping or away from your grow room when the light needs to be turned off or on, your plants are going to suffer.

They require a strict routine that they can predict. They can’t afford to be in darkness or under light for too long because it will compromise their health.

Always set your lights on a timer for strict regulation.

How Many Lights You Should Use

Your lights aren’t going to work well if you’re not using them properly. So I said you have to look up specific led grow light reviews to understand the details better.

You need to make sure you have the right amount of lights placed in the right locations to provide adequate coverage for all of your plants.

To start, you’re going to need a precise measurement of your grow room. Because light bounces around, it’s important that you measure the entire area that you’re growing in, rather than just the area that your plants are situated in.

If you need to decrease this area, placing reflectors around your plants is the simplest fix.

The watts listed on an LED grow light may be deceiving if you don’t understand what they mean.

LED grow lights often don’t operate on this wattage but instead, use this capacity to preserve the longevity of the light.

The actual output will differ, and this is the number you need to use in your calculation.

Ideally, you’re going to want 25 watts per square foot of grow space.

Among all of the best grow lights, LEDs are special because LED grow lights will tell you exactly how much square footage they’re intended to cover.

If the light does four square feet, you’re going to want to place the lights so they slightly overlap to provide your plants with uniform coverage.

Since your plants are absorbing this light, don’t try to cram as many plants as possible into a small space. Your plants need to be spaced evenly to provide them all with an equal amount of coverage.

Crammed plants will suffer because they aren’t receiving the light adequately.

Where to Place Your Lights

Traditional lights will need to be placed several feet above the plant to protect them from heat, but LED grow lights can be placed much closer since heat is not a concern.

LED lights are not as strong, so placing them too far away from your plants can hinder their growth.

If you are ready to invest decent money in some of the best indoor led grow lights, you can be sure that different features will allow for more precise lighting in different places and heights.

Don’t be afraid to place LED grow lights too close.

While many of them are able to penetrate several feet into the plant canopy, that doesn’t mean you should use that as your distance.

As low as three feet from the top of the plant will work out fine, and allow you enough space to examine and care for your plant. As high as five feet will also work.

What Environments LED Grow Lights Work In

You may have read online that certain lights work better in certain circumstances.

While this is true for most traditional grow lights, this isn’t necessarily true for LED grow lights.

As long as the environment is indoors, a LED grow light will work.

This means all kinds of grow tents, sheds, rooms, closets, converted garages, and windowless greenhouses are suited for LED grow lights.

LED grow lights work just as well for soil-based grow systems as they do with hydroponics systems.

If you’re questioning whether or not LED grow lights will work for your environment and medium, the answer is yes.

So you know very well what to look for when searching the best lights for indoor growing.

These lights are engineered to work just as well in every possible configuration of an indoor grow project.

Can You use LED Grow Lights for Growing Plants?

Young tomato plants

Or to be specific, is it better to use LEDs for indoor growing?

Let’s not make things complicated here.

Light is necessary in order for a plant to grow. It is a vital element in order for a plant to develop and nurture.

That’s why, whatever someone says of LED grow lights due to competition, LEDs can obviously grow plants no matter what, since again, because it generates light.


LEDs are somewhat different from others. Why?

Simple, because it is so efficient in terms of utilizing energy, and generating effective light unlike with other grow lights that use a tremendous amount of light while at the same time producing vast amounts of scorching heat.

And also massive cost because other grow lights, unlike LEDs, need more electricity in order to run optimally.

Long story short, you are wasting unnecessary energy and money.

So, if you are the type of individual who prefers efficiency rather than extravagance or the like, I would highly recommend you purchase an LED grow light.

How Good are LED Grow Lights for Plants?

This one question can sum up all of the reasons why you must purchase an LED grow light.

The thing here is efficiency.

Yes, efficiency is pretty much everything that you need.

When you have the efficiency, you can produce significant-quality growth while at the same time not spending too much on your plants, therefore maximizing the profit if you happen to be doing business with your plants.

In my experience, I am certain that among any type of grow lights out there, LEDs beat them out in terms of efficiency.

Are White LED Lights Good for Growing?

The answer for that is most likely in between yes and no.


Because white light is not really the primary light that plants need.

White light is more of a supplemental light that promotes certain kinds of help for a developing plant.

Meaning, this spectrum of light is not really good for growing, but rather a good supplement for an effective and optimal growth for your plants.

So if you have the choice to include white light in your growing process, it is better if you get a hold of it because it’s not actually harmful to your plants even if you exposed your plants to it for a very long period of time as it doesn’t produce that much heat that could cause bleaching on your plants.

Depending on what you’re growing, you may not be able to afford to skip the benefits of an LED light.

LED lights run much cooler than any other lights because they focus more on the type of light they’re producing than they do the sheer amount of light they emit.

While most models of LED grow lights will contain their own internal cooling systems, this is more for the benefit of the internal components than it is for your plants.

The light comes from frequencies instead of raw power, so LED lights aren’t heating up your grow room and scorching your plants.

You won’t need a full cooling system to keep them going

Any grow room needs some kind of air circulation for the benefit of the plants, but cooling isn’t as much of a priority as it would be with lights that generate heat.

LED lights are built to deal with all the needs of your plants, through every stage of their growth.

The majority of LED grow lights won’t require you to buy supplemental lights and gear for plant support.

These functions are already built into your light. One purchase handles it all.

Though you can easily already see the amount of money a LED will save you in cooling costs and the elimination of extra gear, one of the biggest benefits of LED grow lights is the minimal amount of electricity they use.

Since they are focused on frequency rather than brightness, they’re not drawing up as much power as other kinds of lights.

If you’re growing as little as 25 plants or as many as 1,000 using LED lights can cut your energy usage by as much as half.

This doesn’t even count the operating costs of the additional gear you may be using otherwise.

They’re the most efficient grow lights, and that efficiency will become your total energy savings.

While LED grow lights mostly are more expensive outright, they’re worth the investment.

This doesn’t only relate to your energy costs, but also to the longevity of the lights themselves.

On average, an LED grow light lasts about 50,000 hours. That’s fifteen years. Premium grow lights can last double that, making for 100,000 hours of grow time.

You won’t need to replace LED grow lights as often as you would older grow lights because they’re going to last you such a long time.

Many LED grow lights have Zener protection.

This means that a few bulbs blowing will be an isolated incident that won’t travel across the whole lightbox.

A lot of them have modular designs that mean replacing bulbs or upgrading your box is easy to do on your own.

If you’re constantly maintaining your lightbox appropriately, this can extend the life of your lights indefinitely.

Replacing the bulbs as they blow means you may never have to buy a new LED grow light outright.

Of course, if you are looking for something specific, you should read thru some led grow light reviews, in order to understand which solution is the best for you.

Why Choose LED Grow Lights?

Led lights shining on a plant

People have been using Plasma, Fluorescents, T5 grow lights, HIDs for a long time now. While all of these systems are definitely different, it’s not their differences, but rather what they have in common, that makes them all less efficient than LED grow lights.

What is more, different LED light reviews approve great results for people working with them!

The startup cost with a lot of these lights is less expensive, which is what the allure is in the first place.

In truth, everything but regular fluorescents cost an extravagant amount of money to run.

Because these lights are so bright and concentrated (they are trying to replicate the sun, after all), they’re driving up your electricity costs to insane sums.

Lights like plasma lights are indeed very good, but they can cost thousands of dollars a day to run.

Yes, you read that right.

Though fluorescents are inexpensive to run, you need to think about how a fluorescent light would stack up against the sun.

These lights aren’t only driving up your electricity costs by running, but also by generating heat.

In order to maintain a suitable temperature, you need an effective cooling and exhaust system.

When these lights are filling up your grow room with potentially harmful heat, you’re going to have to run special equipment to keep it cool.

Not only does that go towards your electricity costs, but you also have to buy all that gear. This means the best grow lights will affect your work in different ways.

It adds a new level of complication to the process because the temperature will now be something you have to strictly monitor.

Other lights aren’t targeted to your plants and are not providing the necessary wavelengths for certain stages of their growth.

This will likely mean you’ll need other lights to supplement blooming and vegetation. That’s more things to buy.

That’s more you need to keep up with. That’s yet another layer of complexity that you don’t even need to deal with.

LED grow lights solve all of these problems

An LED grow light serves a multitude of functions and even eliminates the need for extra equipment in many circumstances.

LED lights contain ultraviolet and infrared lights, just like your plants would be exposed to in nature.

Yes, you can grow without ultraviolet and infrared, but your plants will suffer in their absence. These light frequencies help nurture your plants, particularly with budding.

Best LED Grow Lights Brands

First things first, a lot of newbie growers start their inquiry with, “what brand is that, bro?”

Well, this question is not surprising.

Pretty much everyone will most likely base their choice and purchase if that brand is quite popular.

Yup, that’s actually the main thing.

At any particular time or place in any kind of industry, the quality of some prominent brand is more credible than those who aren’t really showy and does not have a lot of advertisements.

I wouldn’t probably bet my hard-earned money with some unknown product that has not even a single review or appearance in a particular medium.

With that said, without any mixed business matters let me truthfully tell you the most trusted brands.

  • Apollo Horticulture
  • Galaxy Hydro
  • Grow Northern
  • Advanced Platinum Series
  • Lumigrow
  • G8
  • Trulite
  • Mars Hydro
  • Roleadro
  • KingTM
  • Ocean Revive

That is my list.

Final Key Points to Keep in Mind Before Buying

LED grow lights are generally awesome across the board.

Some of the best LED lights still come with special features that make their usage easier. While some of these features are not absolutely necessary, it doesn’t cost much more to find LED lights that are preloaded with all the bells and whistles.

For the simplest use, choose a full spectrum LED light that can easily be adjusted for both flowering and vegetative stages of growth.

This means you are looking for the best indoor grow lights that provide the kind of features.

Choosing an LED light with a warranty always helps, but may not be necessary.

These grow lights are built to last long, and if you have a faulty light, you’ll know almost immediately.

Lights with a modular design will allow you to perform repairs and upgrades with relative ease, and this is a plus if you’re willing to become savvy. Being able to service and customize your own light can help you save money in the event you decide to experiment.

You’ll find that most lights work fine as they are, but if you’re a tinkerer by nature, this feature is a plus.

Lightweight lights are easiest to move and install

If you think you may move to a larger space within a few years of growing, these lights will make the process easier.

If the light doesn’t require a ballast, this is even better.

Now, here’s what everyone is here for…

How many lights will I need for my grow tent?

This depends on the coverage a specific light provides. Every light will tell you in its specifications how many square feet the grow light will effectively cover.

You’ll most likely need multiple lights to cover a tent, as cross coverage will be necessary to make sure the light is falling evenly.

How many watts do I need in an LED grow light?

Watts can be misleading. Often times, a light may say it’s 400 watts, but it doesn’t run to that capacity.

That extends the lifespan of the grow light.

You need to pay attention to the power draw because that’s what’s most important. Calculate from that number.

Try shooting for 25 watts per square foot of growing space to assure maximum efficiency.

Can you dim LED grow light bulbs?

While a lot of LED grow light bulbs are currently dimmable, there are still some LEDs that aren’t able to do this.

Because LED grow lights eat a small amount of wattage, many kinds of dimmers don’t function with LEDs in the same way that they do with high wattage bulbs.

While dimming an LED you may see the following:

  • Little quantity of dimming range, usually around 80-90% range versus 100% with incandescent.
  • LED grow light bulbs don’t easily shut off at the lowest dim setting. The reason is that the dimmer thinks that the bulbs are fully shut off because of the low amount of energy an LED bulb eats.
  • On dimming systems that are based on Power Line Carrier technology, LED grow lights could flicker when modules are linking because of the small fluctuations of power on the line.
  • LED grow light bulbs don’t change color when dimmed, meaning they will really not offer a smooth fiery glow when dimmed similar to an incandescent.

So that’s it, if you want your grow light to have the ability to be dimmed or not, it’s your choice if you would purchase one that has dimming setting included.

Do LED grow lights really work?

Well, of course, this is quite the troublesome question.

Some individuals are really skeptical when choosing a grow light. But of course, we can’t blame them because they just want the best results.

And also, there are those groups of individuals that are getting paid by some competitor company by giving bad reviews on our lovely LED grow lights.

But again, of course, we can’t blame them, they just want to earn some bucks and thrive in the real world.


Here’s the thing. I am an experienced indoor grower who just happens to have a lot of experiences when it comes to growing indoor.

And what I really want to say is, I’ve got enough experience to testify that LEDs do really work wonder (especially for my weeds)!

I just love the results from the first time I used this kind of grow light.

I’ve noticed various advantages after utilizing LEDs unlike with my previous type of grow lights (for those who are asking, LED grow lights are the last type of grow light that I’ve used, that’s why I’m sure of their worth).

Why choose an LED grow light over any other kind of light?

LED grow lights are the most efficient, hands down.

You won’t believe how much you can save in electricity costs by switching to, or starting with, a LED grow light system.

Their longevity is astounding when compared to the lifespan of other grow lights, they make temperature control for your grow room easier than ever, and the better spectrum they offer will boost the yield of your plants.

How much money should I spend on an LED grow light?

That really depends on exactly what you’re trying to accomplish. There are excellent budget lights, as well as platinum quality lights that are worth the price tag.

It’s worth spending close to $1,000 per LED light if you’re going for a maximum efficiency system, especially if one light will serve the use that multiple budget lights will and you don’t need supplementation of any kind.

Less serious growers, or personal hobby growers, can do just as well with a light under $500.

What is the right distance to hang a grow light?

This will vary with other types of lights. Some lights need to be placed farther from the plants to prevent scorching, or heat damage that can do severe damage to your plants.

LED lights can generally be placed a lot closer to the plants without causing any damage because they run much cooler.

How long do LED grow lights last?

Generally, the minimum lifespan of an LED light is 50,000 hours, though most people find they can run one for up to 60,000 hours without an incident.

This is about fifteen years’ worth of grow time!

Some LED grow light brands boast that their lights can last up to 100,000 hours, which is several decades.

However long yours lasts, you won’t have to replace it often.

What is a light cycle?

You’re trying to imitate the sun for your plants. A light cycle is more or less artificial day and night. Your plants will require different light cycles for different phases of their growth.

Generally, they’ll need about 18 hours of light a day while they’re growing, and 12 hours of light a day while they’re budding.

Leaving your light on constantly will seriously damage your plants, and not providing enough light will stunt their growth.

Do LED grow lights work for vegetables?

Well, since LED grow lights do possess the two primary spectrums that a plant is required, obviously it can be utilized for the vegging stage of your plant.

Therefore it also can be used for various vegetables to grow indoors.

In fact, some studies say that LED grow lights’ blue spectrum, which is responsible for effective vegging growth of the plant, is most efficient compared to the other type of Grow lights such as HID, HPS, MH, and so on.

If a particular plant gets some good amount of quality light without excess heat being generated at the same time by the grow light, the plant would then grow more effectively because no unwanted elements such as unnecessary heat would be involved.

In addition, because the blue light spectrum of LED grow lights is of better quality than the other kind of grow lights, it will give more emphasis on developing the leaves of certain plants.

Due to that, if a plant has some blooming, vigorous, and vibrant leaves, the process of photosynthesis which is primarily involved in the development and growth of the plant, then, of course, it would produce a great number of quality yields.


Some of you might be asking about the heat that is generated by LED grow lights, whether it is more beneficial than the other type of grow lights.

And the answer is yes!

In fact, LED grow lights are more known because they don’t generate that much heat since their bulbs don’t really focus on the great amount of illumination that is being produced instead it is the quality of the light that is more being more emphasized.

Meaning, LED grow lights don’t produce much light and thereby, less heat. And of course smaller expenses due to electricity bills!
