VIPARSPECTRA 300W LED Grow Light – A Detailed Overview.

Before Going Further in this Viparspectra 300W Review, This is an LED Grow Light for beginner level and we can’t expect MUCH out of this.

Yeah, We’ve stated it correctly and we’ve underlined “MUCH” because this grow light has everything that’s expected from a basic grow light for growers of beginner level.

And, it lacks few of those amenities which are generally found in fancy high budgeted LED Grow Lights.

Now, let’s talk in detail about Viparspectra 300 watt LED Grow light.

Viparspectra 300W LED Grow Light: Features

Basically, Viparspectra has designed this light for beginners as we already told you.

But, they’ve not designed a Cheap and useless light as it too has several things where not even a high budgeted grow light will beat this grow light.


As we all know affordable doesn’t mean cheap. And this is not a cheap Light but it’s an affordable light which comes at an attractive price and enlightens your indoor grow tent with efficient and bright light. It saves your $$$ in all the way initially.

It’s a value for money product by viparspectra.

Light Efficiency: PAR Output

PAR means Photosynthetically Active Radiation and it’s the measure of the intensity of lights for plants.

With naked eye we can’t measure actual efficiency of a light. Hence, PAR is used for measuring the intensity of light emitted by any Grow Light Panel.

In other words, if we have a grow light with more PAR value means the light is able to provide our plants with more intense light and our plants will sustain better health because they’re getting better light for the purpose of the photosynthesis process.

If we talk about PAR Value in the Viparspectra then it has 300 PAR (umol m-2s-1) from the height of 24” and from a height of 18” PAR value will be 483 PAR (umol m-2s-1) which is pretty good at this price.

Design Of Viparspectra V300

Viparspectra V300 have a form factor of 12.6” X 7.9” X 3” and it weighs around 5.6 lbs.

Quality of LEDs

Viparspectra 300W LED Grow Light is equipped with 60pcs of Epileds/BridgeLux LEDs. Which is known for its reliability and superior quality. This LED chips are durable and can stay in working condition for a longer time.

Focusing Angle

Focusing angle refers to the angle of light cone that is created by the primary lens of an LED. This phenomenon is normally ignored by buyers but in reality, it matters when it comes to light penetration of plants in your grow tent.

In Viparspectra 300W grow light focusing angle will be of 90 degrees by which a cultivator can achieve better canopy penetration and plants sustains better health and growth afterward.

Which is definitely required in order to get heavier and higher yields during harvesting.

Cooling Ability

More the heat, more the loss.

You remember the point we stated earlier? Yeah, it’s an affordable grow light and it’s not a cheap LED Grow Light because Viparspectra took very good care of everything in this affordable and beginners grow light as well.

This Grow Light is equipped with multiple cooling fans and upgraded aluminum heat sink which takes very good care of the temperature inside grow tent.

Not Waterproof

We believe that things become easy if automatized. But, this grows light doesn’t include any timer or self-controlling device.

We should not expect these all things from a basic level grow light, but it would make things easy and safe if included.

Even after clearing all these things, there are several questions that can arise in anyone’s mind.

Viparspectra 300W LED Grow Light : Clear the Confusion

Now, we’ll take a brief look at those questions.

Are you ready?

How many plants can I grow with single Viparspectra LED Grow Light?

Yeah, to be precise we’d recommend the maximum of 2 plants inside your grow tent if you’re using viparspectra 300W LED Grow Light.

Yeah. You got it correct. We won’t recommend large number of plants with this grow light.

As stated earlier 2’ X 2 is the maximum coverage area for this grow light. And it would be much of the plant density if you’ll grow more than two plants under 4 sq.ft of grow space.

It’s an Affordable Grow Light. So, Quality of materials is doubtful. Is it true?

No, not at all.

This grow light is an affordable grow light and not a cheap one that comes at a lower price with low-quality materials used for its build.

You’re getting highly durable and reliable Bridlux/Epileds LEDs.

This grow light is made using High quality panel and upgraded aluminium heat sink. Thus, quality of materials isn’t a dubtful point here.

What I will get in the box, If I buy this grow light?

The package of this affordable and beginner friendly LED Grow Light includes following things.

  • Viparspectra V300 LED Grow Light X 1
  • Hanging Kit X 1
  • 6ft Power Cord for connection. X 1
  • User Manual X 1

I just want to start Growing in 3’ X 3’ of growing space then should I buy this grow light?

If it’s going to be your first growing experience then we recommend you to start with 2’ X 2’ of grow space and Viparspectra 300W LED then later on you’re free to extend your grow space with the second LED as this grow light comes with daisy chaining ability.

If you still want to start with 3’ X 3’ of grow space then there are other better grow lights available with more coverage area.

Like Viparspectra 600W LED Grow Light is an affordable grow light for beginners with 9 sq.ft of the coverage area.

Why Coverage Area of Viparspectra 300W LED Grow Light Is Different in blooming phase?

Yes, it’s true that many manufacturer will state different coverage area for vegetation and blooming.

Because during vegetation plants don’t need more intense light and can sustain better health and growth with comparatively less intense light.

And, during blooming plants need more intense light. To provide with more intense light we decreases the distance from canopy which results in less footprint on the growing surface.

And as we already stated Viparspectra V300 doesn’t have freedom of control over brightness. thus, by hanging it accordingly we can provide our plants with what they need.

These all are the very common questions which we’ve come through while taking opinions about beginner’s first harvesting experience.

If you still have any doubt or question regarding why to use LED only and not any other grow light then we’ve explained whole LED Phenomenon here.
