Introduction

ViparSpectra is a leading brand in the LED grow light industry with a long history of 10 years. ViparSpectra continues to use advanced manufacturing technology to bring revolutionary changes to the industry, serving over 20 million customers worldwide.

XS series is Vipar's latest led grow lights in 2021, which is a kind of QB LED lights with high performance. XS series contains three types of models in wattage, namely, XS 1500 with 150W, XS 2000 with 240W, XS 4000 with 480W. Featuring in Samsung LM301B diodes, Mean Well HLG driver, XS series improves plants yields up to a max of 2.9g/watt. It has high efficacy with 2.9 umol/j PPE. The PAR value of XS 1500 rises to 1470 at the hanging height of 12 inches. Besides, XS series is delicately designed with an advanced heat dissipation system. This article guides to 10 highlights of ViparSpectra XS series and why it becomes the best LED grow lights in 2021.

Top 10 highlights about Viparspectra XS series:

  1. Industrial-leading Samsung LM301B Diodes

The XS series are designed with Samsung LEDs, including 3000K warm white, 5000K white, 660nm deep red, and 730nm IR LEDs. These LEDs give your plants full spectrum coverage ideal for all stages of growth with high efficiency up to 2.9 umol/J. From seedling to flower, XS grow lights will perform and can increase your yield by up to 50%, compared to standard blurple style lighting.

Built-in diodes in three models:

-- XS 1500 possesses 288 LEDs

-- XS 2000 has 504 LEDs

-- XS 4000 combined with 1008 LEDs

  1. Excellent Mean Well HLG Driver

The Mean Well HLG driver ensures a long lifespan of over 100,000 hours with perfect working performance. The HLG of Mean Well is the industrial-leading driver model as it delivers 94% power efficiency and consumes less electricity. Maximum 2.9g/watt yields bring big earns to growers!

  1. PAR Value -- Higher PPFD, Larger Harvest

It is known that PAR value is a key parameter for measuring the actual efficiency of led grow lights. But what does PAR valuer really mean? And the PPFD and PPF?

-- PAR is the photosynthetic active radiation. The wavelengths that make up the PAR are between 400 and 700 nm used for photosynthesis.

-- PPF is the flow of photosynthetic photons. It is expressed in micromoles per second (µmol / s) and is the quantity of PAR photons emitted per second in the light beam.

-- PPFD is the flux density of photosynthetic photons. It is expressed in micromoles per second per m² (µmol / s / m²). It allows us to quantify on a given surface, at a given distance from the illumination, the number of PAR photon incidents per second.

As we have tested in multiple real conditions, we’ve got real PAR values for XS series grow lights. Here are the details:

XS 1500 PPFD: 1470 umol/m2/s at hanging height of 12 inches, tested in 2x2ft grow tent.

XS 2000 PPFD: 1794 umol/m2/s at hanging height of 12 inches, tested in 2x4ft grow tent.

XS 4000 PPFD: 1822 umol/m2/s at hanging height of 12 inches, tested in 4x4ft grow tent.

From the above data, we can see, XS series efficiently distribute light to large areas. That is beneficial for a big increase in plant yields, almost 50% more than other cheap LED grow lights.

 

  1. Super High Efficiency -- 2.9 µmol/J PPE

Photosynthetic Photon Efficacy (PPE) is the PAR photon output of a light source (measured in micromoles per second or µmol/s) divided by the input power (Watt) to produce that light.

XS series has a PPE rating of 2.9 µmol/J. That means XS generates much usable light with less energy-consuming. For most growers, improving plants growth to the utmost is what they pursue. ViparSpectra XS is the right choice that gives the best efficacy!

 

  1. Passive Cooling

Good heat dissipation is essential to ensure long-time brightness for plants vegging and blooming. ViparSpectra XS series led grow lights have been structured with an aluminum heat sink. It is designed to extend the cooling area that ensures excellent heat dissipation. The brightness of diodes will turn to decay with long-time high-temperature burning. XS series optimize its cooling system by increasing 30% in heating emission which drastically slow the decay speed of diodes.

 

  1. Natural Light with Full Spectrum

Sunlight is the best light for plants growing and cultivating. That is because natural light contains a full spectrum, which play a vital role in plants vegging, blooming, and fruiting. XS led grow lights cover the electromagnetic spectrum from infrared to near-ultraviolet (all wavelengths), ranging from rooting spectrum, vegetative spectrum, to flowering spectrum. They can deliver usable lights to plants in all growing stages.

 

  1. Flexible Dimmer Knob

The dimmer design frees growers from complicated brightness control. ViparSpectra led lights have built a dimmer knob on the unit side. Growers will find it quite easy to adjust light intensity from 5% to 100% in brightness. With the growing stage varies, this knob is very useful for growers to operate in real cultivating occasions.

  1. IP65 Water-resistant Board

The coated solid glue on each chip greatly avoids moisture effectively and increases the board lifespan. Widely compatible with multiple indoor environments.

 

  1. Guaranteed Local Service

ViparSpectra offers 3 years warranty, 30 days duty-free refund & return, local warehouses, and fast delivery. To provide better after-sale services, global warehouses are built in most countries, including the US, CA, AU, EU. As a result, fast shipping and local support are available for all of our customers.
