ViparSpectra XS1000 LED Grow Light

The introduction of marijuana laws has created a new breed of cannabis cultivator — the recreational home grower.

Unlike the commercial cannabis grower, recreational home growers harness small areas to grow enough cannabis for their needs — whether they are medical or recreational.

Today, we’re going to take a sneak-peek and review the ViparSpectra XS1000 LED — the home cultivator’s new best friend for growing marijuana indoors.

First Impressions — Unboxing The ViparSpectra XS1000 LED

The recently released ViparSpectra XS1000 LED is something we couldn’t wait to get our hands on.

After a few days of waiting — our dream came true, and the discreet package of the ViparSpectra XS1000 LED arrived.

Upon unboxing, we were satisfied (as usual with ViparSpectra) with the professional packing job. The XS1000 was completely secured, and there wasn’t any damage during shipping.

Once we pulled out the LED, we were delighted with the overall weight, finish, and design. Everything, from the slick chrome finish to the array of diodes, looked high-quality.


Once unboxed, it was time to see what the ViparSpectra XS1000 was made of.

We can’t stress how convenient the ViparSpectra XS1000 is. Remember, there is no assembly required because the entire unit is a seamlessly integrated design.

The only responsibility on our end was to plug the LED system into a suitable socket. Once plugged in — a blast of intense PAR light illuminated the entire room.

The XS1000 LED is ViparSpectra’s smallest XS model. However, we felt that the light coming from the XS1000 was comparable to that of the recently reviewed XS1500 model.

What’s Inside The ViparSpectra XS1000 LED Grow Light System

Next, let’s take a look at the internals of the ViparSpectra XS1000 LED.

Samsung Diodes

Similar to ViparSpectra’s other LED units, the XS1000 harnesses the power of Samsung’s LM301B diodes.

The LM301B diodes are less prone to burning out, and so far, we haven’t found any dead diodes after running the system for hours on end.

Furthermore, the onboard diodes provide a cascade of PAR lighting. From 5,000 K to 660 nm — the LM301B diodes pack the perfect color spectrum for cannabis plants.

Mean Well LED Driver

When you want efficiency — there’s nothing like Mean Well’s HLG LED driver.

The numbers don’t lie and Mean Well’s HLG driver provides 94% efficiency, greater than 50,000 lifetime hours, and low weight. In other words, the ViparSpectra XS1000 LED is an optimized grow light that’s meant to last.

Passive Cooling Mechanism

Unlike other LED grow light systems, the ViparSpectra XS1000 LED harnesses a passive cooling mechanism to deter heat build-up.

Instead of using a noisy fan, the XS1000 utilizes real heat sinks that efficiently dissipate heat in a snap. Therefore, the XS1000 runs silent and dumps heat effortlessly.

Dimming Options

Last but not least is the onboard dimming switch on the ViparSpectra XS1000 LED.

In our opinion, a grow light must have a dimming switch. This is because of the various growth stages that cannabis cultivators encounter during the marijuana lifecycle.

From seedlings to flowering cannabis plants — a dimming switch allows growers to customize the lighting intensity. Ultimately, the XS1000’s dimming switch enables growers to use this LED from germination to harvest.

Who The ViparSpectra XS1000 LED Is For

As it stands, the ViparSpectra XS1000 LED is marketed as the perfect light for a 2.5′ x 2.5′ space.

In other words, the ViparSpectra XS1000 LED grow light is ideal for home gardeners that grow marijuana in closets or small grow tents. However, growers can purchase multiple units to cover a larger grow area.

Overall, the light footprint covers 2.5′ with relative ease from our experience. However, larger areas may experience less efficient light coverage — especially the outer zones.

Ultimately, we’re thrilled by ViparSpectra’s new family member — the XS1000 LED grow light.

From the moment we turned the XS1000 on, we knew that this LED grow light is top-quality. From its intense PAR lighting to its 3-year warranty, we wouldn’t hesitate to recommend this capable LED to any cannabis cultivator.

Whether you grow cannabis in a small space or you desperately want to lower your electricity bills, the ViparSpectra XS1000 is a beautiful and powerful LED system in a small package.

If you’re ready for high-quality LED lighting that won’t break the bank, look no further than ViparSpectra’s capable XS1000 LED grow light today!


  • High-quality Samsung diodes
  • Adjustable light dimming knob
  • High efficiency that significantly boosts yield
  • Incredibly affordable
  • Perfect for small indoor spaces


  • Not large enough for big grow rooms

MARS HYDRO TS 1000W Led Grow Light

If you’re looking to bump up your overall yield into the 1g/watt category – then the Mars Hydro TS 1000W LED grow light is exactly what you’ve been looking for.

Although the Mars Hydro TS 1000W LED grow light adds roughly 5-7 degrees to your overall grow space, it’s an exceptional trade-off considering the light footprint, power output, PAR rating, and overall efficiency.

The Mars Hydro TS 1000W LED grow light system fits ideally into a 2’x4’ tent, which is a popular option for many home-based cannabis cultivators.

However, growers can add additional units to increase the overall footprint. By doing so, multiple Mars Hydro TS 1000w LED grow light systems can be harnessed by commercial cannabis growers to increase their overall efficiency.

Considering the significant bump in light output, the Mars Hydro TS 1000W LED light does emit a modest level of heat. However, this can be lowered easily by incorporating oscillating fans within the grow room, along with inline fans, to allow adequate air exchange.

Additionally, we thoroughly enjoy the fact that this LED is full-spectrum. This increases the PAR rating because the range is firmly within the usable range for cannabis plants.

Whether you’re beginning the vegetation phase or 6-weeks into the flowering stage – the Mars Hydro TS 1000W LED grow light does it all.


  • Fanless LED Grow System
  • Consuming only 150W with 342 LEDS
  • Highly Rated


  • May Not be the Best for Flowering

Why Switch to a 1000 Watt LED Grow Light?

If you’ve grown multiple cannabis crops in the past with a power-hungry HID (high-intensity discharge) light, you know how large your electricity bill can be at the end of the month.

When your plants are in the vegetative phase, the lights are left on for 18 hours out of 24. This stage of growth can last anywhere from one week to 6 weeks – depending on how large you’d like your plants to be.

This accumulation of time significantly affects your cost of operations, since each minute of lighting is costing your a certain dollar value.

Once you’ve completed the vegetative phase, it’s time to move onto the flowering stage. Although this phase of growth requires less lighting (12-hours), it still aggregates over time because this process takes between 7-11-weeks to finish.

After considering that you’re looking at 8-17 weeks of lighting, which doesn’t include the lighting required for seed germination, clone propagation, mother maintenance, or the juvenile growth stage.

Another aspect that you’d need to take into consideration is how many HID lights are required to cover your given canopy space.

Most of the time, 1 600-watt HPS light isn’t enough to cover a 4’x8’ grow tent. As you begin to place additional lights into your grow room, you exponentially increase the cost of electricity.

Once you switch over to a 1,000-watt LED grow light, you immediately reduce your energy consumption. Although LED companies label their lighting systems as 1,000-watt, they draw far less energy from the outlet.

Typically, a 1,000-watt LED grow light will consume upwards of 400-watts of power; thus, consuming a fraction of energy compared to a 1,000-watt HID.

By slashing your power bill in half, you can spend these savings on additional tools, new cannabis genetics, or better yet, place them into your bank account.

Although a full spectrum 1,000w LED grow light isn’t exactly equivalent to a 1,000w HPS, they offer additional benefits that outcompete traditional HIDs.

The Benefits of a 1000 Watt LED Grow Light

It goes without saying that a 1,000-watt LED grow light significantly reduces your electricity bill. Aside from your main electricity bill, there are many benefits associated with owning a 1,000-watt LED grow light.

Save Water

As the temperature within your grow room increases, the moisture within the medium begins to evaporate. Your cannabis crop will start to wilt, which is a clear sign of heat stress.

This is a scenario that countless growers face when using HID lighting in an enclosed grow room without an effective ventilation system.

Most of us think that we can get away with a miniature AC system, but in reality, we’re trying to reduce our overall costs.

Instead, you’re putting your plants into a precarious situation by forcing them to walk on a tightrope.

Inadequate ventilation will leave your plants stressed while the intense heat from a 1,000-watt HPS is bearing down on them.

The main advantage of a LED grow light is that it reduces the heat in your grow room, which simultaneously decreases the plants’ water needs.

If your room isn’t hot, then your plants intake water at a reasonable rate according to their size. The medium doesn’t lose moisture quickly when the temperature isn’t soaring into the triple digits.

Reduce Your Carbon Footprint

Although most of us don’t think about it, we place a high amount of stress on the planet with our needs.

It’s important to realize that the amount of energy that’s necessary to power multiple HID lighting systems is unsustainable.

Now that cannabis cultivation is legal in many states, the amount of growers is increasing. If every grower is compelled to use LED technology, we can reduce our overall power consumption and energy use.

By reducing our energy use, we can sustainably grow cannabis. The more sustainable our cultivation practices, less stress is placed on the environment.

Implementing LED technology will reduce our overall carbon footprint and improve our lives.

Save Money on Bulbs

You’ll no longer need to buy separate MH or HPS bulbs once you’ve switched over to an LED grow light. Most LED grow lights are customizable, meaning you can choose which color spectrum at any moment.

This is done by the use of a remote controller or by buttons located on the LED grow light itself.

Reduce Your Weight

Traditional HID lighting requires heavy equipment to power each bulb. Magnetic and digital ballasts weigh roughly 30-40 pounds each. A power cord is attached to the ballast, which then joins the hood and bulb.

Most growers keep the ballast outside of the grow room because it generates heat while its in operation.

Ballasts are generally fixed to walls or placed in a safe area on the ground. It’s challenging to put ballasts on a wall due to their weight, so it’s common to find these pieces of equipment on the ground.

Instead, a 1,000-watt LED grow light doesn’t require a ballast. This automatically reduces their weight, which makes them incredibly easy to hang within your garden.

Increase Your Safety

As stated previously, traditional HID lighting requires the use of a ballast. Once your room consists of more than one ballast, you may find yourself in a dangerous situation.

Many growers place their ballasts on the floor, with wires crisscrossing in all directions. This presents a specific fire risk, which does occur often.

Ballasts are also prone to overheating or malfunctioning, which increases their overall safety concern.

LED grow lights reduce this concern significantly by not requiring a ballast for operation.

These are solid state devices which have far fewer points of failure while in use, which makes them considerably safer to use compared to HID lighting.

Cannabis and LED Grow Lights

This is where many skeptics doubt LED grow lights. They claim that LED lights don’t produce large and resinous cannabis flowers.

This myth has perpetuated through many growing circles, which has led to many avoiding this beneficial technology.

In fact, LED grow lights have been studied to grow a wide variety of crops effectively. Most LED grow lights even come equipped with IR and UV, which adds a new component that’s natural to sunlight for increased plant growth.

Since LEDs are composed of diodes, each diode is capable of producing a particular color light. LED growers enjoy the benefits of being able to cycle between red and blue lights at a moments notice.

What To Look For When Buying a 1000 Watt LED Grow Light

Here are a few tips on what to look for before you purchase your first 1000 watt LED grow light.

Power Output

Before making a substantial investment into a 1000 watt LED grow light, you want to make sure how much power it consumes.

In general, a 1 000 watt LED grow light will draw 400-500-watts of power. At this range, it’s producing an intense light that will adequately cover a 4’x4’ area.

Some manufacturers produce 1,000-watt LED grow lights that are rated at far lower wattages.

Marketing schemes are abundant within the LED industry, so it’s crucial that you research how much power a given LED grow light draws.


Weight is another vital factor to consider before buying a 1000 watt LED grow light.

Are you growing in a tent or room? If you’re growing in a tent, then you must obtain a LED grow light that weighs a modest amount.

This is because you won’t normally place just the LED light above the plants. Other tools, such as carbon filters, inline fans, and oscillating fans are hung from the roof as well; so it’s essential that your LED grow light doesn’t weigh too much.

Each manufacturer will always include the weight of their LED grow lights, so make sure that you understand this simple fact before making a purchase.

Quiet Fans

One of the main selling points of heavy-duty 1000 watt LED grow lights are their onboard fans. The fans are quiet and keep the entire system running cool.

If you’re hoping to build a discreet grow space, then a quiet built-in fan is a must when shopping for a 1,000w LED grow light.

Traditional HID lighting also offers onboard ballast fans, but these are known to cause a large amount of noise.

Even though these founds sound like they’re working on overdrive, the result is still an overly warm ballast.

LED Chips

LED chips come in a variety of wattages, with the most common for cannabis production being 3-watt, 5-watt, and 10-watt.

The higher the rating, the hotter the diode becomes during use. Although a 10-watt diode will produce a brighter light compared to a 3-watt diode, it emits over double the amount of heat.

Therefore, it’s essential to know which diode a certain product contains.

Aside from the watt-rating, you should also understand which LED chip is used. Not all LED chips are created equal, and it’s best to find a LED grow light manufacturer that uses brand name LED chips.

Examples of name brand products are:

  • Cree
  • Nichia
  • Toyoda Gosei
  • Osram
  • Phillips Lumileds
  • LG Innotek
  • Edison Opto
  • Seoul Semiconductor

When you’re diving into the mechanics of your LED grow light, make sure that you see these brand names to ensure your diodes are made with high-quality materials.

Color Spectrum

Cannabis production requires specific wavelengths for the best results. The preferred wavelengths fall into the red/orange and white/blue range.

The reason behind this need for a specific color spectrum is due to the natural lifecycle of a cannabis plant.

Cannabis is an annual plant, which means that it germinates, grows, flowers, and reproduces within a single year.

Cannabis plants are phototropic, which means they respond to certain levels of light.

During their primary growing season, daylight hours are extended due to the summer months, and the natural color spectrum is blue/white. This is because the sun is high on the horizon.

As the daylight hours decrease and the summer season begins to transition towards fall, cannabis plants recognize the red/orange color spectrum that’s associated with a sun closer to the horizon.

This phototropic stimulus drives them to switch to the flowering stage of their lifecycle.

This is why growers prefer to use the blue/white color range during the vegetative stage and the red/orange spectrum during the flowering stage.

By mimicking the natural wavelengths found in nature, cultivators can give their crops the most ideal environment to grow in.

PAR Rating

Not all light is created equal. This is because plants interact with light in a range of usability. 1000 watts of any kind of light isn’t as efficient as 1000 watts of light fixed at a specific photosynthetic range.

LED lighting has a clear advantage over traditional HID lights because they’re built to operate within a range that’s ideal for photosynthesis.

As you may know, photosynthesis is the primary function for the majority of plants to produce energy.

The ideal range for photosynthesis to occur is between 400-700nm. Many LED grow lights have a high PAR rating, but it’s imperative that you seek a product that caters to plants within this range.

Grow Room Size

We always mention grow room size because this is a critical factor that you’ll need to understand before making any kind of purchase.

A 1000 watt LED grow light will optimally cover a 2’x2’ to 4’x4’ grow space, but what if your room is larger or smaller?

You’ll need to measure your available growing area before you make a substantial investment in a LED grow light.

Although LED grow lights emit minimal heat, your efficiency may decrease if you place a 1,000w LED grow light in too small of an area.

If you find yourself in a large room, then you’ll need to purchase multiple 1,000w LED grow lights to ensure a fully-covered canopy.

Advantages of LEDs Over Traditional HID Systems

LEDs are better than HID systems in many ways. Let’s take a look at how 1,000w LED grow lights out-compete 1,000w HPS and MH systems.

Long Lasting

1,000w full specrum LED grow lights are incredibly long-lasting. Their chips are generally rated for over 10,000 continuous hours of use.

Competition amongst LED manufacturers has skyrocketed in the last few years, which resulted in companies offering chips that last longer than 50,000 hours.

Traditional 1000 watt HPS or MH bulb are changed replaced after 2 grow cycles. HPS and MH bulbs aren’t cheap, and these replacements incur a significant cost throughout your career in cannabis cultivation.


1,000w LED grow lights can be turned on and off without the risk of failure. In contrast to metal halide and high-pressure sodium systems, you won’t have to worry about destroying your light if you need to turn on your light suddenly.

When you turn off a HID system, the ballast needs time to cool down before it can turn back on.

The process of turning on an HID system takes a large amount of power, and it’ not recommended that you cycle between the on and off state frequently.


We’ll be the first to admit that we’ve fumbled a brand new HPS light bulb as we took it out of its box. Seeing a $120 light bulb shatter before our eyes was soul-crushing.

Although we don’t recommend that you drop your new 1000 watt LED grow light onto the ground, they’re far more durable than traditional HID lights.

A 1000 watt LED grow light is a near solid-state device. All of its components are built within the system, and you won’t hear any of its mechanics jingling around as you transport it.

The body of LED grow lights are encased in rugged aluminum or a heavy-duty and heat-resistant plastic.

Compare this durable design with a metal halide or high-pressure sodium bulb, which is made of delicate glass.

Quick Warm Up

When you switch on a 1000 watt HID system, do you note how long it takes for it to turn on completely? It takes roughly 1-minute to boot, which is a long time compared to that of a 1000 watt LED grow light system.

A 1000 watt LED grow light system turns on instantly. The moment the timer reaches the predetermined time, your LED grow light will emit its powerful rays upon your crop.


Many 1000 watt LED grow light systems benefit from customization. It’s not uncommon to find systems that come equipped buttons that allow you to select your preferred color spectrum.

Some 1000 watt LED grow lights even offer green color options so you can view your cannabis crop at night without stressing them.

Low Heat

This is the game changer. Low heat reduces water loss, decreases your electricity bill, and increase your overall efficiency.

Your cannabis plants will thank you with an abundant harvest by providing them with an optimal grow room temperature.

Reduce Electricity Bills

What will you do with the money you save from switching from a 1000 watt HID system to a 1000 watt LED grow light?

As the threat of global warming looms across many states, electricity providers are continuously increasing power rates.

California, for example, charges 15.2 cents per kWh. Hawaii residents pay a sky-high rate of 33 cents per kWh. Each state varies, but one fact remains the same: electricity isn’t cheap.

This is why it’s crucial to begin your new cannabis endeavors with a power-efficient LED grow light system.

A 1000 watt LED grow light is potentially the best bang for your buck, but ultimately, only you can decide if it is or not.

Is a 1000 Watt LED Grow Light Right for You?

This is the question that we all hope to answer. After you’ve read through our list of aspects to consider, do you fall into the category that can benefit from a 1000 watt LED grow light?

If you’re a commercial producer, then you can surely benefit from reducing your overall production costs. This is the goal in any industry, and improving your efficiency should be one of your primary aims.

As a hobbyist grower, the same desire for efficiency should be your primary goal. The more cannabis you produce at a lower cost will make growing marijuana a profitable business.

If it costs more to grow cannabis then buying it directly from a dispensary, then your effectiveness is low.

This is why it makes the most sense to use a power-efficient 1000 watt LED grow light compared to any other lighting system on the market.


After considerable review, we’ve come to find that the best 1000 watt LED grow light is the ViparSpectra XS1000 LED Grow Light.

The ViparSpectra grow light comes with everything that you’ll need to use it right out of the box and it’s competitively priced for LED grow lights in this range.

The 3-year warranty is a major bonus in our eyes because diodes will go out. It’s generally not a mistake on the manufacturers’ side, but it’s just a common occurrence that diodes go out over time. Since this LED grow light system is rated to last over 3-years, you’ll be covered for the majority of its lifespan.

The full-spectrum color scheme will leave your grow room looking like a professional-tier operation. Cannabis plants won’t be able to resist the perfectly balanced PAR, UV, and IR lighting that comes from this LED system.

Within your first month of use, you’d see significant savings that will go towards paying off your new LED.

Overall, there are many competitors in the field of LEDs. The options are endless when it comes to full-spectrum LED grow lights, but the ViparSpectra XS1000 LED Grow Light came out on top because its value outweighs the other options.

If you’re fully ready to join the LED community, then starting with a 1,000w LED grow light is the best choice.

The ViparSpectra XS1000 LED Grow Light is our top pick, but each and every grower has their own needs. Take a look at our top options and decide which is best for you!
