Viparspectra XS1500 Review (2021)

Viparspectra is one of most popular LED grow light manufacturers.

The brand’s goal is to make affordable grow lights for growers.

The XS series is Viparspectra’s newest grow light series, and it’s designed using the latest technology.

To find out more about the performance of those lights, I decided to examine the XS1500 model. Below, you’ll find an in-depth Viparspectra XS1500 review.

Viparspectra XS1500 Review

First, let’s look at the light’s package and design.

Package and Design Review

Viparspectra XS1500 comes in a well-packaged box, surrounded by protective foam from all sides.

Inside the package you’ll find the light, a power cord, hanging equipment, and a user manual.

The power cord is around 6 feet (1.8 meters) long and it’s thick and well-insulated.

The hanging equipment includes a wire hanging kit and adjustable light ratchets. I used both to hang my grow light (I’ll show you how I did that below).

In the user manual, you’ll find safety information, the specifications of each light in the XS series, installation tips, and warranty terms.

Besides the user manual, you’ll find a cute leaflet that asks you if you’re satisfied with the product or not.

I am impressed by this leaflet because it shows that the brand cares about its customers.

But in the end, what matters most is the light’s performance.

Unlike the brand’s older lights, Viparspectra XS1500 has a very simple design which mimics that of a quantum board.

The LED board has 288 LEDs. Most of those diodes are from Samsung, and they have 3000K (warm white) and 5000K (white) spectrums.

The remaining diodes consist of 15 deep red diodes (660 nm) and 1 infrared (or far-red) diode (730 nm).

Coating the LED panel is a layer of silicone that makes it waterproof.

A very heavy aluminum heat sink with a wide surface area covers the LED panel.

The large surface area of the heat sink is the result of its straight fin design.

That improves heat dissipation, and for this reason, the device doesn’t need to use any cooling fans.

The grow light’s driver is from MEAN WELL and it’s fixed to the top of the device.

Viparspectra XS 1500 also has a dimmer that allows you to adjust the intensity from 5% to 100%.

How Can You Hang the Grow Light?

There are few ways you can hang a grow light, but it’s always recommended that you use ratchet hangers so you can adjust the distance between the light and your plants.

The installation manual of Viparspectra XS1500 doesn’t show you how to use the ratchet hangers with your light.

To install my Viparspectra XS1500, I hooked the wire hangers to the device then hooked the ratchet hangers to the wire hangers.

I then looped the ratchet hangers around the pole and clipped them to their rope.

If you have a grow area with a low ceiling, replace the wire hangers with shorter ropes to bring your device higher.

Performance Review

To examine this light’s performance, we must first look at its spectrum.


Nowadays, manufacturers are focusing on optimizing the spectrums of their grow lights as more studies about the effects of light quality on plants come out.

By comparing the new series to the older ones, it seems that Viparspectra is working hard on enhancing the spectrums of their devices.

Viparspectra XS1500 spectrum

Compared to Viparspectra’s Reflector grow lights, XS1500 has a spectrum that is far richer in red light and that has a higher red to blue light ratio.

Viparspectra XS1500 also emits small quantities of far-red and infrared light.

Besides that, the light puts out good quantities of green light, which is important for plant growth and productivity (learn more green light’s importance for plants).

Overall, the spectrum of Viparspectra XS1500 resembles that of Quantum Boards (QBs).

QBs are known among growers for their superior performance that can pull the highest yield from plants. But most QBs come in DIY kits and they’re more expensive than Viparspectra XS lights.

Intensity and Efficiency

Viparspectra XS1500 has a PAR output around 370 µmol/s.

With that PAR output, the device can cover a growing area measuring 2’ x 2’ (0.6m x 0.6m) during the flowering phase.

The light’s PPFD at the center of the growing area is 1175 µmol/m²/s (at 14 inches above the canopy).

Viparspectra XS1500 draws around 150 watts of power only at 100% intensity.

The brand says that the PPE of its device is around 2.9 µmol/J, but according to my calculations, the value is around 2.5 µmol/J, which is still very high.

Other features

The LED of Viparspectra XS1500 can live over 100,000 hours (around 11 years of continuous usage). Note that any grow light’s performance will start to decrease after it reaches the final third of its lifespan.

If your Viparspectra XS1500 has a quality issue within 30 days of its arrival, you can choose to replace it, get your money back, or repair it for free.

There is also an extended warranty for 3 years that covers the reparation costs of any manufacturing defects that can cause the light to stop working properly.


Compared to other grow lights with similar performance, Viparspectra XS1500 is very affordable.

It’s the perfect choice for growers who want to achieve outstanding results without paying too much money on grow lights.

I recommend it for both professional and amateur growers.

Important Notes:

  • Stick to the manufacturer’s recommendations to get the best results.
  • Don’t bring this light too close to your plants and don’t look directly at it (even if it’s at 5% intensity).
  • Don’t subject the device to extreme environmental pressure (high temperature or high moisture levels).  

Summary and Final Words

Viparspecra XS1500 is a high-quality grow light that has a very optimized spectrum and high intensity.

It has a great heat dissipation system that relies on its wide aluminum heat sink.

Since it’s designed like a quantum board and uses Samsung diodes, you can pull out a very high yield using Viparspectra XS1500.

The device is for perfect for all growers because it’s very inexpensive.

I can vouch for Viparspectra XS1500 and I am 100% sure you won’t be disappointed with its performance.
