Viparspectra PAR600 600W LED Grow Light Review [2024] – is it Worth Buying?

Last Updated on December, 2023 by Rob Wilson

Grow lights, as most growers who have been growing marijuana for quite some time would know, are one of the most essential equipments for growing weed. It is with the help of grow lights that plants are able to grow even when sunlight is absent while growing indoors. They form the backbone of the entire growth process and one of the best grow lights available in the markets for growers who are growing in a small-scale setup is Viparspectra PAR600 600W LED grow light. Here, we take a closer look at this grow light and provide a detailed review about each and every aspect that you should know about! We shall also be taking a look at some frequently asked questions about this grow light that buyers often tend to have in their mind.

Viparspectra as a brand is pretty popular and we will also give an insight into the brand. Over the course of this article, not only shall we be discussing the Viparspectra PAR600 600W LED grow light in detail along with what its pros and cons are, but we shall also attempt at understanding what grow lights are in general and what is the importance of these lights. Let us now begin with the basics:

Introduction to Grow Lights

When your marijuana plant grows outside under the sunlight and open skies, it gets the light it needs from the natural sources. However, when you grow the plants indoors, there’s usually no access to sunlight and hence you need to simulate this light via artificial sources. The perfect artificial source for recreating sunlight inside your grow tents and grow rooms is an LED grow light. These lights are a great means to ensure that your plants grow really well. 

The sunlight isn’t all the same – there are various wavelengths and colors of light. Primarily divided in the blues and the reds, the blues are the cooler spectrum of light which helps the plants during the vegetative stage and the reds are the hotter spectrum which is required by the plants during their bloom phase. Grow lights (and in particular LED grow lights offering full-spectrum lighting) are just the perfect solution for growing plants because they are very similar to the natural light of the sun as they bring to you the red spectrum and the blue spectrum along with ultraviolet and infrared lights together.

Apart from LED lights, there are a number of different types of grow lights available. There are High Pressure Sodium (HPS) grow lights, Metal Halides, CFL grow lights, among others. However, these are all considered pretty ‘old school’ these days and modern growers have all migrated to LED grow lights which are cheaper to operate and can last for a much longer time while providing a significantly better growth leading to higher yields! The Viparspectra PAR600 is one such grow light which can easily replace these older lights. 

Growers must remember that grow lights are critical for the growth of the plant as the primary function they play is that they allow the process of photosynthesis to take place. Photosynthesis is the process where the marijuana plant converts light into energy which is essential for its survival. Also there’s a direct relationship between optimum lighting and high yields. 

Viparspectra: Is it a credible brand?

Any grower who has been growing for some time – or even a rookie who is still researching and learning the ropes is bound to have heard of Viparspectra. It is one of the biggest brands in the markets when it comes to growing marijuana indoors. The company makes not only grow lights, but also a number of different types of growing equipment other than lights. Viparspectra has been in the markets for close to 10 years now and the company’s grow lights have been extremely well-performing. The brand’s credibility is really high and fetches quite a bit of resale value as well for the growers who might want to upgrade after a few years of usage. Let us now take a detailed look at the Viparspectra PAR600 600W LED Grow Light review and examine various aspects of this grow light:

Viparspectra PAR600 600W LED Grow Light Review (2022) – is it worth buying?

Here’s a detailed review of every aspect of this grow light, going through which will help you make a much better and well-informed choice before you buy this grow light. 

1. Design and Durability

In terms of its design and durability, this grow light is actually pretty good. Divided into two sections with heat dissipating fans placed in the center, this grow light measures 14.1×11.8×3.5 inches- which makes it pretty wide and actually quite thin compared to many other lights in the markets. When you look at the weight of this grow light, the Viparspectra PAR600 600W LED grow light actually weighs a little less than 14lbs and is just the right size and weight to be hung inside a grow tent without putting too much pressure on it. 

On the sides of this device, you can find heat vents from where the heat can escape the light. The back of this grow light, quite uncharacteristically, is completely plain and offers the growers with just the space from where you can hang it to the top of the tent. The fans are located on the front panel which divide the lights in two sections. One one of the sides, there are three switches – marked Red, Blue and White. This is unique because most grow lights only have two sections Red for the Bloom phase and Blue for the vegetative phase. Here, you see some white light too, which can be used in combination with the other two. This grow light features sixty pieces of LEDs in both the sections to the left and the right of the fans, featuring a total of 120 5W LEDs. 

Given its thinner design compared to other grow lights, some growers might think it is less durable but don’t go by the size – this is a pretty well protected device and can survive quite a few bumps and falls. The design here is quite unconventional and rather amazing as it totally cuts the bulk off!

2. Spectrum and Light Details

This is a full-spectrum LED grow light, which makes it  very similar to the natural spectrum of sunlight. Basically, this is like a mini sun inside your grow tent which will give your plants all the kinds of lights it needs for an ideal growth to take place. Given that a combination of lights from across the spectrum will give the growers an ideal growing condition, one needs a full-spectrum light in order to grow plants to their best capacity. Here, you get 120 grow lights with an output of 5W each, giving you a total of 600W. The manufacturer has specified that during the bloom stage, you need to turn all three R, W, and B lights on. 

There’s a 12-band full spectrum included in this grow light which comes with lights operating from 440nm to 730nm while there are two other types of lights functioning at 3000K and 7500K. This is a pretty bright grow light and can easily replace an old school HPS/Metal Halide system of 400W while consuming lesser power and providing an equivalent (or better) output! All in all for your plants which are growing indoors, this grow light is actually quite great and will help them grow better and provide higher yields thanks to its full-spectrum lighting.

3. Brand Value and Credibility

Viparspectra stands a cut apart when you compare it to other grow light brands. It is in the category of some of the most trusted names such as PlatinumLED and Vivosun among others. The company has been making grow lights for a really long time and has quite an experience of creating them. Their after-sales support is also really good and growers get an increased revenue per square foot when using this light. What really stands out about Viparspectra is that their grow lights are really durable and high functioning. They work as good as new even after years of usage and fetch growers a good return on resale as well!

4. Coverage Offered

Since this is a high-PAR grow light, you should hang it a little higher compared to regular grow lights. When hung from a height of 34” it covers an area of 3×3 ft which is ideal for the vegetative phase. However, when you move to the bloom phase, you move it a little closer to the plant because the lighting needs are different in both these phases. When you move it down to about 26”, the coverage will drop to 2.5 x 2.5ft. This is ideal for a small grow tent between 2×2 to 3×3 or a 2×3 setup. The PAR performance here is also really impressive (we will get to that in a bit).

5. Power Performance

Viparspectra PAR600 600W LED Grow Light offers the growers with an output of 600W but consumes only about 235W from the power socket, making it really efficient and one of the best LED grow lights in the markets. Another thing about this grow light is that using this, they can easily replace the lighting capacity that a traditional 400W Metal Halide or a High-Pressure Sodium light offers while consuming less power than them! This is one of the biggest advantages of using an LED grow light – eventually, you save so much power that the light pays for itself in the long run, making it a good investment!

6. PAR Values

This is the speciality of this grow light. The PAR values of the Viparspectra PAR600 600W LED grow light are among the best in the business. The grow light offers 1050 uMols when hung from 18”. Even at 24” it gives a decent 700 uMols in PAR score – which is really impressive and effective and helps the plants grow faster, better and produce more yield than they would normally do.

7. Cooling

The cooling infrastructure here is quite unique compared to most other grow lights that we have reviewed in the past. Viparspectra PAR600 600W LED grow light comes with three fans built in the front – as opposed to almost all other grow lights which have fans placed on the top. This arrangement helps make sure that the heat is dispersed off immediately and it does not damage the grow light or the plants at all! There’s an advanced multi-level heat sink system which helps make sure that the heat is dissipated fast and efficiently.

8. Warranty, Cost, and Delivery

Almost all Viparspectra grow lights come with a 3-year warranty and this grow light is no exception. Growers get a three-year warranty on the PAR600, along with a 30-day return period as well where they can return the product if they are not satisfied with the quality or the functioning of the light. When you look at the cost of this grow light, it is just $219.99 making it quite affordable, even for those who are just starting out. Delivery, as always, by Amazon is quite fast and efficient.

Frequently Asked Questions (FAQs) About LED Grow Lights

1. Are LED Grow Lights Legal?

Yes, LED grow lights are legal to use and you can order them anywhere and carry them around without the worry of law enforcement getting after you. However, in areas where growing marijuana is not legal they might raise a red flag and people might suspect you are doing something illegal. Remember that using a grow light is legal but growing marijuana may not be legal everywhere around the world. Always check with the local law enforcement authorities before you begin the process of growing weed. 

2. How much light should I provide to my plants?

The amount of light that you should be providing your plants depends on which stage of growth they are in. The younger they are the more light they need. In seedling stage, the light needs to be far from them but it needs to be on for about 18 to 20 hours, in the vegetative stage, you need about 18 hours, about 16 in pre-flowering and about 14 to 12 hours of light to trigger the growth of the plants from the pre-flowering stage to the flowering stage. Hence, the amount of light you provide to your plants largely depends on their stage of growth.

3. Why are LED grow lights considered better than other grow lights?

LED grow lights are considered better than other, older forms of lighting because of multiple reasons. First off, these grow lights consume much lesser electricity when compared to these older forms of lighting – ultimately paying off for themselves in terms of the energy saved. Moreover, they are non-toxic in nature and can be disposed easily. Lastly, these grow lights last much longer compared to regular grow lights. LED grow lights can last you over 100,000 hours if you use them correctly.
