We’ll begin with a short introduction to the brand as we believe it helps in determining trustworthiness and reliability for users.

As far as Viparspectra is concerned, it is a brand known for customer satisfaction and requirement fulfilment.

You can imagine its value by looking at the number of extensive product lines each dedicated to a specific purpose of grow light in indoor growing jobs.

Viparspectra has been producing for indoor cultivators for more than 8 years and built its reputation over time.

So, now dive deep into its specification details and features.

Also, we’d start with the features that captured our attention and forced us to craft this Viparspectra Dimmable Series PAR450 Review.

Features That Makes It One of Its Own Kind

A few features we love about the Viparspectra dimmable PAR 450w LED grow lights are below:

  • The first thing we liked about it is three separate dimming knobs. Generally manufacturers provide 2 dimming knobs at max, but Viparspectra also offers white light dimmer. With the help of these 3 dimmers you’ll have extreme control over brightness and effectiveness of color blending.
  • The second feature we think is unique is 2 powerful fans with dimensions of 3.2” on the front side of the panel. Generally manufacturers provide cooling fans at the backside of the panel, but Viparspectra Dimmable Series PAR450 450W Grow Light features it on the front side. Initially, it was an experiment to improve heat dissipation. And guess what? Viparspectra succeeded with this front side fan design.
  • The third point is PAR Test Results. Yeah, in this case, it can beat even some of the 600-900W LED Grow Lights on the market. We must say that with best PAR results even some of the top-rated brands in the same price and wattage segment will fail to beat Viparspectra PAR Series.
  • At last, we’d like to admit that it’s a symbol of heavy duty build and perfect design.

Now, we’d begin with our detailed review on Viparspectra Dimmable Series PAR450 LED Grow Light features:

Spectrum is the key to success in your indoor growing job, as we often mention. As far as Viparspectra Dimmable PAR450 LED Grow light is concerned, it is equipped with 34 Red LEDs, 26 Blue LEDs, 26 White and 4 IR/UV LEDs.

Yeah, it is the most ideal ratio of blue and red by keeping overall growth and lifecycle of plants in mind. If we look at ranges of color bands, it ranges between 440nm to 730nm.

Also, the overall ratio of Blue:Red: White in light effect is 5:3:2 which is measured as an actual effect in the spectral graph created by real bright effect created inside the grow tent.

However, during the flowering phase lowering blue effect and maximizing red effect will help in getting best yields using this grow light.

Moreover, This grow panel is designed by keeping overall growth and flower quality in mind, and hence they relied on significant blue for better growth during vegetation.

The Viparspectra Par450 will in turn provide you healthy and heavy buds coated by smooth resin.

PAR Results – How Intense The Light is?

As we mentioned in our attention-grabbing features of PAR450, results obtained by this grow light concerning PAR tests are remarkably unbeatable.

Yeah, from the height of 24” it provides around 600 uMol in test results.

However, we must say, ideally recommended height for a grow light is 18”. So you’re free to tinker with the height as you will.

Even some of our readers informed us that using Viparspectra Dimmable Series PAR450 is much better than their previous grow light they used.

Coverage Capability – What about it?

Now, as you’re familiar with PAR and Spectral capabilities of PAR450 grow light, you can imagine for what amount of area this grow light is an ideal fit.

However, Manufacturer recommended that this grow light is ideal for 2.5’ X 2.5’ of growing space from the height of 32” during vegetation and during bloom it can cover around 2’ X 2’ of grow area from the height of 24”.

Moreover, our recommendation says that while growing marijuana your plants should be as much closer as possible and also you should consider testing the height by observing plant leaf to ensure they’re not getting burned due to close light.

I recommend to keep it at 18” during blooming and 24” during vegetation, so according to our expert’s final opinion coverage that it’ll provide will be around 3’ X 3’ during veg and 2.5’ X 2.5’ during bloom.

Yeah, we aim to get maximum out of Viparspectra Dimmable Series PAR450 450W LED Grow light without any light waste.

Power Efficiency – Is It Pocket Friendly in Long Run?

The key factor that we believe as a primary concern from user’s point of view.

Yeah, an ideally perfect choice should not be economically imbalanced, and that’s what we want our readers to keep in mind while making their decision for choosing the best LED Grow Lights.

We’re glad to inform in this Viparspectra Dimmable Series PAR450 Review that it is entirely budget friendly concerning power efficiency as well.

Yeah, it just pulls on around 200W±3% which is entirely acceptable from a grow light with this level of PAR results and customization options.

Depending on your dimmer settings it’ll increase or decrease by 3%. So, at max, it’ll pull around 206W when you set all the dimmers at max.

Well, from power consumption’s point of view it passes the test with its performance.

Cooling and Heat Dissipation – Positive OR Negative?

While all other brands are stuck to the old and traditional way of heat dissipation systems, Viparspectra comes up with something fresh and unique.

Yeah, Instead of placing cooling fans at backside they’ve used front side as a preferred location in their Dimmable PAR450 Series.

In Reality, it was an experiment but resulted in positive effects inside grow space, and they’ve used this way for their product line.

Yeah, Viparspectra Dimmable Series PAR450 450W LED Grow Light is equipped with 2 fabulous yet silent cooling fans on the front side of the panel.
