Since cannabis has a number of benefits and has hence been declared ‘legal’ in many of the countries around the world, people are looking for ways to increase its production right at home. The LED grow light is a great addition to your growing area as it has a number of benefits for these indoor plants.

Each cannabis plant needs precise lighting, air, water and other essentials in order to grow and to give you a good yield. So, since lighting is one of the pre-requisites for the growth and development of the plant, I personally found these LED grow lights to be a blessing for cannabis.

In this LED grow lights review, I have short-listed ten best LED grow lights, and will discuss the features and specs of each in detail. Here’s a glance at my top 10 list, in the order of significance:

You may be concerned about causing any sort of damage or overkill to your plant. But let me assure you, these lights when used right, are the safest.

Many of these lights are equipped with fans and cooling sinks that help keep the temperatures low and also keep the plant from wilting. In fact, let me tell you, these LED grow lights have a number of benefits. Here, let me pen some of the major advantages of these for cannabis growers:


Benefits of LED Grow Lights

Listed are few top reasons why you need LED Grow Lights.

Temperature Setting

If you are looking for optimal growth of your plant and want to ensure that it doesn’t wilt or get burnt in any way, the right temperature is the key. While cannabis needs the warmth of the sun, it also needs to stay cool.  Remember, too much of the sun can wilt, burn or destroy the plant. The LED lights just get warm to the touch and hence, the chances of your plant getting destroyed or burnt are minimal.

No need to Ventilate

These lights are surprisingly powerful but keep their cool. This, in turn, leads to your room temperature staying cool as well. Since they are least likely to produce much heat, you can absolutely dump the idea of getting a separate cooling or ventilating system installed at home.

Portable, and Easy is to Relocate

These lights aren’t just affordable, but also quite compact. You don’t need much space or a designated corner for the light. In fact, it gives you – and of course your plant – the liberty. You can set them up anywhere in your home, no matter which room or corner, the lights are really easy to set up.

Easy Installation

The installation is simple and really easy. Since these are very compact you can just place them over your plant on your desk or by the wall. In fact, you can also use a combination of these lights to get a wider coverage area if you are growing more than a single plant.

Longevity, Last a Long Time

These LED grow lights have a long life. Typically a grow light will last anywhere between 50,000 or even 100,000 hours. That means 7 to 8 years on average.

More Control, Adjustable Wavelength, and Wattage

A great thing about these lights is the increased control you can have. You can adjust the wavelength and even the wattage. This way your plant will be getting exactly the light wavelength and intensity it needs at that particular stage.

Energy Efficient

Now one thing that is hands down the best about these LED lights is that these are very energy efficient. As compared to the other sources of light – excluding the sun of course – the LED lights do not draw much power, so you can stay assured your electricity bills won’t be a major concern once you get one of these.


Best LED Grow Lights Reviews  – Top 10

Time and again technology have introduced us to some of the best alternatives to the natural sunlight. You may have come across the florescent lights, high-pressure sodium lights, etc. LED lights are the recent addition to these alternate sources of lighting. Trust me, you will find these much better and reliable as compared to the others as they only produce little heat and it’s also not much of a hassle to cool them down.

So let me take you through my top 10 picks for the best LED Grow lights:


1.- Advanced Platinum Series P300 12-band – FULL SPECTRUM.

Advanced Platinum Series P300 300w 12-bandThe Advanced platinum series makes it to my top pick of all these LED grow lights. Not only is this affordable but it gives you the coverage of about 4.5 * 3.8 feet. But even if you are looking for a wider coverage, you can just keep two or more of these lights adjacent to one another, and voila! You are a genius!

Another interesting comparative feature of the light is that it has a much greater PAR/lumen as compared to the other grow lights. In simpler terms, the light is quite intense, you can say about 2-3 X higher than the others.

Plus, it comes with cooling heat sinks and fans for making sure the unit stays cool.

Perhaps the best thing about this light is that there’s a focusing lens for the light. In fact, there are two lenses in this LED light. One of these is the 60-degree lens and this 90-degree focusing lens so that your plant gets a more intense light directly on it.

This light uses only 180 watts to give you a high powered lighting. Energy efficient, portable, with a 12 band spectrum and a 5-year warranty, this has to be the best LED grow light you’ll find in the markets.



2.- VIPARSPECTRA Reflector-Series 450W – Full Spectrum.

VIPARSPECTRA Reflector-Series 450WNext, in line, I’ve placed the Viparspectra reflector-series 450W LED grow light. This one beats many of its counterparts due to its price, features, and looks.

If you need a grow light for a small area, say about 2*2 or 3*3, this is the optimal size for you. Whether you want aesthetics, features or quality, this one has it all!

As for the light spectrum, you get multiple options. There’s the infrared LED, red and blue, and many others that you can turn on or switch off according to the growth cycle or stage of your plant. I can vouch for this much, this is the best LED grow light when your plant is in its flowering and vegetative stage.

Another interesting feature is the fans and the cooling heat sinks made of aluminum. All these help to keep the unit as well as the surrounding cool. The lights are really easy to hang, last a long time and come with a three-years warranty.

Let me tell you another detail; the LEDs of this one have a reflective coating around them. This is very helpful in increasing the intensity of the light as well as the PAR output.

I can say without a doubt that the quality, sturdiness, and efficiency of the light make it a great option for growing cannabis at home.



3.- Roleadro 300w LED Grow Light Galaxyhydro Series.

Roleadro 300w LED Grow Light GalaxyhydroTake a look at this one, the Roleadro 300w LED Grow light that uses 3W EPileds LEDs that gives you a much higher output than others.

This comes with the Infrared and ultraviolet lights, that I can tell you will have a great impact on the total yield. Other key features that make it one of my favorites are the sunflower radiator system, three cooling fans, wide coverage and increased penetration of up to 150%.

The radiator system ensures a much better heat distribution and keeps it cool. A great thing about this light is the angled LEDs. In my experience with these lights, I learned that this angle placement at 120-degree increases the intensity, coverage and the PAR output of the lights. In fact, if we talk about the covered area, then this light is the best for a 40″ x 40″ area.

Plus with a two-year warranty and 30-day complete refund guarantee, things just can’t get any better. All-in-all, this is perfect not just for cannabis, but for all kinds of indoor plants and vegetation, and that too with such an attractive price tag!



4.- California Lightworks NEW SolarStorm 880W with UVB

California Lightworks NEW SolarStorm 880W with UVBNext, I have placed the California Lightworks solarstorm 880W. I cannot emphasize just how strong this light is. With the UV-B and high OSRAM SSL emitters, it can give you a high yield. In fact, let me tell you, this is the only LED grow light you’ll find that has the UV-B spectrum. And since the natural sunlight has UVB – and a lot of it – this is as close to the natural lighting, as you can get.

This UVB is emitted through the T8 fluorescent bulbs that can be adjusted with a dedicated control. If you make use of this light during the last phase of the growth, it will definitely have a great impact on your total production.

It does come with a steep price tag, but will definitely have a greater impact on the overall yield than the others in its league.

This is hence, my highly recommended option if you are looking for harvesting more of the crop or for wider area coverage.



5.- Marshydro Reflector 960W LED Grow Light Full Spectrum.

Things you must know about LED Grow Lights

Before you set out to buy these LED lights, make sure to go through LED grow lights reviews before making your pick. Plus, there are definitely some of the pointers you must keep in mind.

Like for starters, a bit about the mechanism of their working will give you more insight about what kind of LED grow lights you should be looking for.

Inside the LED grow lights, an electric current flows through the semiconductor interior. The current makes the electrons glow and emit light. The color of the light can be changed by using different kinds of the semiconductor material placed on the inside.

Now I’ll discuss some of the terms and specifications of these LED lights that’ll further make it easier for you to pick the right one.

  • Wattage

Wattage is the measure of the total energy of the LED lights at their full capacity.

The wattage or the limit for the usage is usually mentioned in the box or specifications of the LED grow light. But working out the exact wattage can be a bit tricky. For instance, suppose an LED light has a 600-watt capacity.

That does not say that your LED will normally function at this level. In simpler words, the mentioned wattage is the maximum or highest your LED grows light can function at. So what you should be looking at is the actual power drawn by the LED light.

Often keeping the light on at its maximum potential, may result in overheating and may also affect their longevity.

  • Coverage Area

The whole area where the light reaches is another important thing to consider. It is usually measured in feet and is different for small and larger harvests. Make sure to go through LED grow lights reviews to give you an idea of the actual area of the LED.

  • Life

As discussed the long life is one major benefit of these lights that give them an edge over the other sources of light. The lifetime, usually expressed in a number of hours can go from 50,000 up to 100,000 hours.

When choosing your LED light, the longer the life the better. It won’t require a replacement anytime soon; in fact, some of the best LED grow lights last for 7 – 8 years!

  • Wavelength

Since these LEDs are an artificial source of light, you need to check the wavelength. Choosing the wavelength can depend on a number of factors including the lifecycle stage your plant is at.

Tips for getting the Most out of LED Grow Lights


  • Make sure to place the light at the right distance from the plant. Too close can retard growth and if it is placed too farther away, it will reduce its effectiveness. The right distance is usually mentioned in the instructions that come with each set.
  • Buy a voltage stabilizer for your light. It will serve as a means of protection for your LED light and also significantly reduces the possibility of fluctuations.
  • During the vegetative growth phase, use 16-18 hours of light only. For the rest of the day, let the plants stay in the dark.
  • Use about 30% lesser nutrients and less water with the LED lights. Since the temperatures do not rise, the water and other nutrients are not lost.
  • As soon as you see the first flower – this will b at the internodes – I recommend you must make the switch to the flowering light. Change the cycle to 12 hours of light and 12 of complete darkness for the plant. This will give it just the right amount of darkness and light to help it stay healthy and growing.



Last Thoughts about the Best LED Grow Lights.

The LED light can be the best thing you can get for your plant. These are closer to nature’s lighting and quite safe and easy to use. The best part, you don’t have to think about replacement or getting another one for a particular life stage. These LED grow lights have been made to last and are ideal for plant growth from the seedling stage right up to the flowering phase.
