Towards the end of the article, we also attempt to answer some frequently asked questions about grow lights in general which will help answer many questions that even you might have! Let us get right into this by looking at some basic facts about grow lights:

An Introduction to Grow Lights

The marijuana plant requires many things in order for a healthy growth, but proper access to sunlight is one of the biggest needs that it has. However, when you grow your plants indoors, the access to sunlight is restricted. Hence, you need an artificial source of light which will provide the plants with the exact same benefits as the natural light of the sun does. This is where grow lights come into the picture. The best grow lights offer the plants with a near-natural composition of all wavelengths to ensure that the plants are growing properly. 

There are a number of different types of grow lights too, some of them classified based on the chemicals inside them, some based on the shape and the size and others based on the kind of lighting that they provide. When you take an overall look on the entire market of grow lights for growing marijuana, however, it has generally been observed that LED grow lights tend to be the best options that growers have because they offer a higher performance while consuming much lesser power. Here’s a quick look at the importance of grow lights:

Why are Grow Lights Important?

Grow lights are essential for growing plants indoors because they replace the natural light of the sun, as explained above. Sunlight helps the plants grow taller and stronger as the plants convert light into energy via the process of photosynthesis. Getting access to light also ensures the plants grow in the direction of the light source. Furthermore, light also helps trigger certain enzymes and pigments which the plants need for a healthy growth. All of this is made possible with the help of grow lights. They also ensure that lights of all the various wavelengths are provided to the plants to help them with all the stages of their life cycle. 

Viparspectra: Is it a credible brand?

To answer this in one word: certainly. Viparspectra is one of the best names and one of the safest bets for growers who want to buy grow lights. The company has an excellent track record when it comes to manufacturing grow lights. The company claims to have over 1,000,000 users across the world and offers some really great services such as a 14-day money-back guarantee, a 30-day replacement guarantee, and a 3-year warranty period on all their devices. They also offer free shipping all over the US. There’s also a dedicated US helpline for their buyers to reach out to them easily, making them one of the most credible brands for those looking forward to buying LED grow lights.

Viparspectra 1200W LED Grow Light Review (2022) – is it worth buying?

Here, we have reviewed 8 crucial aspects of this grow light to provide you with a complete picture of everything that you need to know about it. Here we go:

1. Design and Durability

In terms of design and durability, this grow light is really good – the same that we have seen and expected from Viparspectra over the years. It measures 19.4×19.4×3 inches, which is pretty large and weighs about 20lbs (which might sound a lot for a grow light but is ok for a 1200W light). The light has a dark grey body with four hoops to hang it located on the back. On the back, you can also find four fan outlets, as well as a power inlet along with two switches – one for VEG and one for BLOOM mode – which is a feature which has been missing from many grow lights these days.. 

On the sides of the panel, you can find multiple vents which allow the heat to pass through so that it does not damage the overall panel. The build quality is quite sturdy and it is very durable too. It is a square-shaped panel which also has quite a focus on safety! This is a UL Certified device which means it has gone through a number of safety tests and regulation standards and has then been considered safe for operation, giving the growers an assurance of safety! There are 240 pieces of LED lights on the panel, divided into two sections of 120 each. Daisy-chaining, however, is one feature that is missing from this grow light (which means you cant plug other grow lights on to this one)

2. Spectrum and Light Details

This grow light offers an optimal spectrum in order for plants to grow properly and provide the best possible yield. Normally grow lights offer a limited spectrum but here you get a full spectrum, meaning the same grow light provides lights enough to nurture the plant right from the seedling stage all the way to the harvest! It offers a 12-band spectrum along with 10 pieces of Infrared lights as well. There are a total of 240 lights here operating at 5W each resulting in a total output of 1200W.

There’s a double channel support of VEG and BLOOM lights. VEG lights include blue and white lights and BLOOM lights are largely the reds and oranges. When you use the two lights together they provide an optimum performance for the plants. It is a good combination to have on any grow light but having a dimmer here would have been another great feature. All in all Viparspectra 1200W LED grow light is among the best choices you have in terms of lighting if you are looking for the best LED grow lights for growing marijuana indoors. 

3. Brand Value and Credibility

We have already mentioned above the high credibility that the Viparspectra brand brings along. It is one of the most trusted and the best names in the markets these days and allows the growers to really get the best out of their plants. Furthermore, one of the best advantages of using a brand as trusted and usually long-lasting such as Viparspectra is that not only does it function great, but it also fetches you a great resale value when you decide to sell it off to get a new grow light. 

4. Coverage Offered

In terms of the coverage that you get while using this grow light, it stands in at about 3.5ft x 3.5ft when you hang it from a height of 24” and about 4.5ft x 4.5ft when you hang it from 32”. Since it is a super bright 1200W light it is not advised to lower it to 18 inches even in the later stages of growth. This coverage is ideal for growers to easily grow between 4 to 6 plants to an optimum level. The grow light also has a great PAR per lumen output but more on that in a bit.

5. Power Performance

This grow light provides an output of 1200W and can easily replace a traditional grow light/HPS grow light of 800W. However, when you look at the actual power consumption from the wall socket, it draws only about 520W (give or take 10%). This makes it very economical when compared to traditional grow lights but some growers still find this electric consumption a little too high for their taste and would prefer a grow light which may be slightly more economical. However, if you put all the other factors together this is simply perfect!

6. PAR Values

The PAR value of this grow light, when hung from a 24” space is 504 uMols and when you hang it from a slightly higher, 32” space, it goes to 268 uMols. Both of which are pretty good figures when you compare the distance from which they are hanging at. Lowering it to 18 inches would increase the PAR score to 870 uMols. This is a very impressive performance when you compare the price you get it for and the wide coverage that it offers. 

7. Cooling

To ensure that the device does not overheat and cause damage to your plants (or does not get damaged itself), there are a number of cooling mechanisms and systems in place. These include four fans on the back of the grow light which make sure that all the heat is taken out of the body of the plant into the grow tent from where it gets sucked out by the ventilation system. There’s a scientifically designed precise aluminum sink which makes sure that all the excess heat is dissipated. It offers a very stable temperature all through the time you use it, and thanks to sufficient outlets all around it, manages heat really well and is not susceptible to thermal damage. 

8. Warranty, Cost and Delivery

There’s a three-year warranty period on this grow light from Viparspectra. The cost of this grow light is just right (not too much and not too little) when you compare it with the features that you are getting in exchange. This is a really bright grow light which will make sure that your plants are getting just the right kind of growth. There’s also a 30-day satisfaction period where you can return or replace your grow light. The delivery via Amazon is on time. All said and done the Viparspectra 1200W LED Grow Light is a great option for growers.

Frequently Asked Questions (FAQs) About LED Grow Lights

Here are some frequently asked questions about the Viparspectra 1200W LED Grow Light that many growers would like to know about.

1. Is it legal to use this grow light?

Yes, it is completely legal and safe to use this grow light to grow plants. However, there’s one legal aspect that you need to take care of: the plant that you’re growing should be legal. Marijuana plants are not allowed to be grown in many parts of the world (and even in some places where smoking weed is legal). Hence it is best advised that you check with your local law enforcement before you start growing your marijuana plants using this LED grow light.

2. How many plants can I grow using this grow light?

This grow light offers you a coverage space between 3.5 sqft to 4 sqft. You can grow as many plants here as you can fit in the space. However, it is best advised to space out your plants properly in order for them to get good growth. You can grow between 4 to 6 plants in this space that you get. However, it totally depends on the technique of growth you are using and how much space you’re giving to each plant.

3. How much light should I give to my plants?

The amount of light you’re giving to your plants depends on which stage of growth they are in. Plants in very early stage of their life cycle require the most light (about 18 hours), in the vegetative stage, plants need about 16 hours of light, 14 hours in the pre-flowering phase and about 10 to 12 hours during the flowering phase – many plants are photosensitive, meaning they require this change in light cycles to move from one stage to another. Hence, based on this you should provide light to your plants. Moreover, you must also know that providing excess light might tire out the plants, so make sure they’re getting enough hours of darkness as well. 

4. Are there any disadvantages of using this product?

As such there are no ‘disadvantages’ of using the Viparspectra 1200W LED grow light. However, we noticed that the fans tend to get a little noisy when you use it for over a year. This is gradual wear and tear and can happen with pretty much any grow light. Another small drawback here is the power consumption which might surpass 500W at times – which isn’t really bad but when you look at similar products from other brands there are some which offer you comparable output with lesser power consumption.

5. What is the warranty on Viparspectra 1200W LED grow light?

All products manufactured by Viparspectra tend to have the standard 3-year warranty. Moreover, there’s also a 30-day replacement period and a 14-day money back guarantee as well. This truly makes it one of the best LED grow lights in the markets right now. 



To conclude, we hope that this review of Viparspectra 1200W LED grow light helped you gain a better insight into everything that you wanted to know about the light. If you are still making a decision about which grow light you should go for, and if this one fits your needs, we strongly recommend you to go for it as there’s one thing that we know about Viparspectra for sure – they do not compromise on the quality of their products!
