The Best Cheap LED Grow Lights – Pictures, Specs and More

What are the best cheap LED grow lights for growing cannabis?

Viparspectra P1000 Pro Series

Your best bet will be a low wattage grow light from brands like Mars Hydro, King Plus, or Viparspectra. These cheap LED grow lights can be obtained for under 200 bucks. Below you’ll discover the best all-around LED grow lights currently on the market.

I tell growers the one thing you don’t want to cheap out on for growing weed, fruit, or vegetables, is a grow light. The reason is these plants need a certain amount of light and the very cheap grow lights won’t produce enough of it.

What Specifications To Look For In The Best Cheap LED Grow Lights:

1. Light intensity:

The best cheap LED grow lights will provide a light intensity that’s enough to grow your plant from seedling to harvest. That means 20 to 40 moles of light per day.

In order to hit the 40 mole level for maximum yield, you want a grow light that emits between 600 uMols (for 18 hour veg) and 925 uMols (for 12 hour flowering) PPFD of light.

As long as you have sufficient light intensity, you don’t need to worry about wattage which is not an accurate indicator of performance when it comes to grow lights. You can read more on this topic here.

2. Good Spectrum:

The best cheap LED grow lights will have a balanced spectrum. Some of the worse performing lights have too much blue or too much red, which leaves you hanging for the Veg or Flowering stage of growth.

Spectrum isn’t a settled science yet, so some grow lights will vary slightly. But generally speaking your LED grow light should use a white spectrum or a balance of blue and red (purple looking). You can find that out by viewing the spectrum chart of each light.

3. Coverage Area:

The best cheap LED grow lights will cover the area you need covered for a good price. Take coverage area claims on lower priced lights with a grain of salt.

Most lights in the “best cheap” category won’t cover beyond 2x2 feet sufficiently.  If you need a larger space covered, consider multiple units, or check out my article the Best LED grow lights for 4x4 grow tents to find lights that cover a larger space.

List Of Best Cheap LED Grow Lights:

  1. Bestva 600w SAMSUM
  2. Mars Hydro TS-1000
  3. King Plus 600w
  4. Phlizon 1000w COB
  5. Viparspectra P1500
  6. Spider Farmer SF-1000
  7. Sansi 36w LED Bulb

Keep reading for the full details of each light.

The Bestva 600w SAMSUM Grow Light

click image above

Bestva has been one of my favorite grow light choices if you don’t plan on buying a COB, Quantum Board, or other high end light. Considering the price, it’s actually not a bad light for a small space. This is the Bestva SAMSUM 600w LED grow light.

It comes with two light modes – one for the Seed/Veg growth phase and one for the flowering phase. The 10 watt LEDs really separate this light from other 600 watt LED grow lights by increasing light intensity and efficiency.

One of the best features of Bestva LED grow lights is the true full spectrum. Even on an entry level grow light like this, they managed to get a perfect balance of blue, red, and a small amount of green which has been found to be helpful up to 24% concentration in some spectrum studies (the Bestva has ~10% green).

You also get the essential ultraviolet and infrared bands, which increase THC and help plant formation and bud quality.

The light intensity (PPFD) for the Bestva 600w LED grow light is middle of the pack when compared to other LED grow lights. It comes in at an impressive 1350 umol, enough light intensity to grow a high yielding cannabis plant.

How does the Bestva 600w compare to similar grow lights? Lined up against the Viparspectra V600 reflector, the light intensity (PPFD) is considerably stronger at ~1350 compared to ~820 on the Viparspectra, which is another popular 600 watt grow light option. 

Coverage area:

The one downfall of this light is the small coverage area, but like I say, you really get what you pay for when it comes to grow lights. If your space is more than 1.5x1.5ft, you’ll need to consider multiple units, or buying the 1200w or 2000w versions which feature larger coverage areas. 

This Bestva SAMSUM 600w grow light comes with a 3 year warranty, and 30 day money back guarantee.

Pros & Cons:

Pros:

  • The strongest cheap LED grow light on the market.
  • True full spectrum
  • 3yr warranty/ 30 days money back
  • Great product reviews
  • Dual light mode switches
  • Highest PPFD readings in 600w grow light segment

There’s really not much need to look further than the Bestva 600 watt reflector series. It offers one of the best spectrums and light intensities among other 600 watt options. The price isn’t bad either. Check out the reviews on Amazon (link below here) and see how customers have been raving about this light for quite a while.

MARS HYDRO TS 1000W

mars hydro ts-1000

best led grow lights

This cheap quantum board LED grow light is the most modern design on my list. I think it may also be the best all around value. It’s not as cheap as all the other choices here but it’s pretty close.

Mars Hydro just introduced this model recently as the indoor grow light industry has shifted towards white spectrum quantum board grow lights.

Why is the TS-1000 one of the best cheap LED grow lights?

Compared to other grow lights on this list and elsewhere, the TS 1000 offers the most value. You’ll get 2x2 feet of light coverage, a white spectrum which is slightly better than purple spectrums, and you get a modern fanless quantum board design.

ts-1000 ppfd

You’ll also get a dimmable ballast, although you won’t need to dim the TS 1000, as the highest intensity of about 500 uMol is exactly what’s needed for the vegetative phase, and wouldn’t require dimming during flowering either.

The TS Series grow lights are very bare bones. You’ll notice there are no cooling fans, but even more extreme is the lack of a power switch. The lights go on when you insert the power cord into your outlet, and vice versa.

Thankfully, Mars Hydro was kind enough to include a single outlet timer so you don’t need to manually unplug the grow light after each day’s light cycle.

How much can you yield with this light? Mars Hydro says you’ll get up to 1.5g/watt from the TS Series grow lights. Keep in mind there are a lot of factors that affect plant growth, so these are approximations.

In summary, this light is a serious competitor to $500 quantum board grow lights that cover the same amount of space as this light. 

A few pet peeves about the Mars Hydro TS 1000:

There’s no on/off switch. Mars Hydro includes a timer that’ll shut the light off at your pre-set interval, but I’d personally still like a switch.

The Mars Hydro TS series spectrum doesn’t include infrared or ultraviolet light, which can have their respective benefits for growing cannabis. A few other models on this list include those spectrum, so decide if it’s a big deal for you.

Pros and Cons of Mars Hydro TS 1000 Watt Quantum Board Grow Light

Pros:

  • Possibly the best value for the money grow light.
  • Good coverage in the segment.
  • Energy efficiency that helps in long run.
  • Modern design

Cons:

  • No Infrared Spectrum
  • No On/Off switch (plug & timer only)

Other Mars Hydro TS 1000W Specifications

  • Dimensions : 14.2 x 13.2 x 2.4 inches
  • Weight : 3.75 lbs
  • Spectrum: Spectrum: 660-665nm, 3200-4200Knm, 5200-6800Knm
  • Actual Power Draw: 150W
  • Coverage: 2’ X 2’
  • Warranty: 3 Years warranty + 30 Days Money back if not satisfied.

Final Note:

Looking at all the features and capabilities the new Mars Hydro TS 1000 series has to offer, I consider it as one of the best cheap yet performance packed LED grow lights in the budget segment.

Decide if this is a good light for you. A lot of other growers have already given it a chance and seem pleased based on the Amazon review comments.

Have a flexible budget and larger than 2x2 space? Check out the Mars Hydro TS-1000’s big siblings – the Mars Hydro TSW 2000 and the Mars Hydro TS 3000W.

Just like the TS 1000, these bigger models provide great value for the respective price ranges and give other lights a serious run for their money!

King Plus 600W LED Grow Light :

best led grow lights

King Plus 600W is chosen as the editor’s choice for Best Cheap LED Grow Light.

King Plus offers a full line of grow light variants. If you’re in need of one slightly larger than the low cost 600 watt model, you can check out my 1200 watt model review here to determine if the larger size is right for you.

The 600 watt is equipped with 60 Dual Chip LEDs of 10W each. These LED spread a full spectrum light all over your grow space. An underlying reason for utilizing dual chip LEDs is to produce more intense light which can balance PPFD and coverage in the most efficient way possible.

King Plus 600W is capable of providing the most elemental spectral effect which is suitable for all the periods of your marijuana plant’s lifecycle.

The spectrum of King LED also includes IR bands which are most essential for cell building and better growth.

The red to blue light ratio is fairly balanced, although it’s a little heavier on red with 56%, so your bloom cycle will benefit extra. Blue wavelength comes in at 30% of the spectrum, and the rest is green which also helps with absorption.

This grow light is useful and at this price your cannabis plants will flourish. It’s a win-win.

Now, if you’re concerned about its ability of coverage, then it is suitable for a decent 3’ X 3.5’ of the area. Which you can increase or decrease based on your requirement and your observation. If you’re looking for an affordable grow light, chances are you’re only growing a couple plants anyway.

What we recommend is to keep the light a bit nearer to the canopies during flowering so that your plants can absorb more light and produce better buds.

King Plus states that this light can replace a 600W HPS system. However, I don’t believe in this replacement factor. Moreover, I recommend readers to look at actual power consumption rather than looking at HPS replacement figures.

This cheap 600W Variant of King Plus LED grow light pulls 120W from the power outlet which justifies its energy efficiency capabilities.

As far as temperature management and heat dissipation are concerned, this grow light is equipped with multiple cooling fans that keep things well balanced inside one’s weed grow space.

In case you face any problems, or any failure occurs King Plus provides a generous 3 years of manufacturer’s warranty.

A good thing about King Plus is usually, they respond to their customers within 24 hours and guides them through the process concerning warranty claims.

That’s all for King Plus 600W LED Grow Light. Now let’s take a brief look at its benefits and drawbacks to make your decision-making process smooth.

I wanted to confirm whether all these stats about coverage, power draw and spectral abilities are right or wrong? After all, for a generous entry level price these are impressive stats. So, I took the opinion of several existing users who are currently growing using King Plus 600W LED Grow light.

I received responses in unison from every existing user that “the stats are right.”

So, based on these responses, we could confirm that King Plus 600W Full Spectrum LED grow light is one of the best Cheap LED Grow Lights that works well for indoor cannabis growing.

Buying King Plus 600W LED Grow Light is the best bet if you want the best LED Grow Light for the money you spend.

And, you want a similar grow light in terms of capabilities then Viparspectra 600 Watt LED Grow Light is also a great alternative. However, for Viparspectra you might need to stretch your budget further to above 100 dollars.

To conclude, the meaning of CHEAP is apparent that it shouldn’t correlate with CRAP. The King Plus 600w grow light is a cheap grow light that works well.

Don’t take it from me, take it from verified owners’ reviews. With over 1,000 reviews and high average rating, I discovered they’re all saying things like “bang for your buck,” “highly recommend,” and “third grow with nice buds and no complaints.” How can you argue with that?

If you don’t find it fits your needs then no worries. Let’s move forward to another LED grow light that works like a charm.

Phlizon 1000W COB

best led grow lights

Another great cheap LED grow light candidate is the Phlizon 1000w COB LED light. This is an LED grow light manufacturer that’s been selling well for a while now.

It’s not the cheapest option but it offers great performance and value for the price which is under $200.

What is COB LED you ask? It’s an LED variant that packs multiple LEDs into one chip. The increased brightness from COB LEDs is noticeable and performs better in your grow space.

Luckily Phlizon has an entry level model for people searching for the best cheap LED grow lights. This is a strong competitor

I’m including the Phlizon 1000w COB grow light due to the COB technology which is a key differentiator on entry level lights.

So, let’s explore what’s in there for this grow light to be worth purchasing.

This LED grow light is equipped with two large COB CREE Chips. It’s a combination of multiple chips which helps in generating extraordinarily intense and more focused light.

The shade of light in this grow panel is pinkish, and it covers all the essential bands of vital spectrum for your marijuana plants. Your plants will get everything they expect from nature.

Also, above all this spectrum is suitable for the entire growing cycle of your cannabis plants.

Now, if you’re concerned about coverage abilities then don’t worry it’s capable enough to cover around 3’ X 3’ feet of growing space.

However, as we always say, it’s up to you to increase or decrease this space by adjusting height. Just as a reminder, don’t forget to keep it a bit close during flowering to gain more resinous buds.

This grow light also features daisy chaining ability that lets you connect another grow light without the need of an extra socket in your power outlet. In case you want to expand grow space, this feature comes handy.

Due to COB integration, Phlizon 1000 Watt COB LED grow light effectively improves the uniformity of brightness and strong PPFD values helps in increasing yield.

Now, comes the main thing to look for in a cheap grow light and that’s the actual power draw. Moreover, as far as this factor is concerned, we’d suggest you to be worry-free as it only pulls around 245 watts from the wall.

Roleadro ensures the safety of your plants by placing multiple cooling fans along with an advanced heat sink. Yeah, heat dissipation should not be an issue anymore.

For customer convenience, they also provide 30 days money back guarantee along with 2 years satisfactory customer warranty.

Viparspectra P1500 LED Grow Light

best led grow lights

This is the recently released Viparspectra P1500 LED grow light. It has all the abilities to justify its place on the list of some of the cheapest LED grow lights on the market.

Viparspectra is a well-known manufacturer when it comes to grow lights. They’ve been around for several years and the Pro Series P1500 is the newest version of their long running LED grow light series.

I bought the smaller Viparspectra P1000 model for myself and use it regularly. The P1500 would be good for 1-2 cannabis plants.

Is the Viparspectra P1500 A Full Cycle Grow Light?

Yes it is. With peak intensity near 1000 micromoles under the center of the light, that’s enough to grow cannabis from seed through harvest. The spectrum is also sufficient and you can read that below.

What’s the Viparspectra P1500 Spectrum Like?

The spectrum is a white spectrum that contains the blue and red wavelengths necessary to grow cannabis through all phases. It contains 640-660nm (far red), 3000-3500K (red), and 6500-7500K (blue).

Power and Hang Height:

The Viparspectra P1500 pulls 150 watts from your outlet. The peak intensity is about 1000 micromoles at 12 inches hang height. That’s strong enough to make a good yield during flowering.

You’ll be able to dim the light easily with a turn knob, or simply raise the light higher, if you need less power.

For Seedlings: Hang the P1500 22 inches above your plants.

During Vegetative Phase or Autoflowers: Hang the P1500 16 inches above your plants.

During Flowering: Hang the P1500 12 inches above your plants.

Coverage Area:

The Viparspectra P1500 will cover a 2x3 foot space. Thats good for 1-2 plants. As a cheap LED grow light it offers a solid bang for the buck.

Spider Farmer SF-1000:

best led grow lights

The Spider Farmer SF-1000 is a newer model LED grow light. It uses similar components to the HLG quantum board grow lights. The value you’ll get with the Spider Farmer SF-1000 is hard to beat if you’re trying to light up a 2x2 foot grow space, or one cannabis plant.

Design:

The design of the SF-1000 is very simple. It’s a flat metal board with LEDs on one side and drivers on the opposite side. This light uses Samsung LM301B diodes and a Mean Well driver. Low power consumption of about 100 watts means the light doesn’t generate much heat. There are no fans on this grow light.

Spectrum:

The light spectrum on the SF-1000 is made up of 660-665nm (red), 3000K (warm white for flowering), 5000K (cool white for vegging) and infrared (IR) 760nm. There’s only one light mode which works for all phases of growth.

My Spider Farmer Experience:

I bought and tested out the slightly larger SF-2000 model, which is ideal for a 2x4 foot grow space (2 cannabis plants). You can read about my experience on my full Spider Farmer blog post, or watch the  videos I made below:

This last grow light in my review is known as a “booster” light. It’s too small to grow a plant by itself unless you’re growing succulents, in which case it’d be sufficient.

But it can be useful for people growing larger plants because they’re good to “boost” your overall light intensity when used in addition to other larger grow lights. You may want to buy one or two to fill out the edges of your grow space. That’s what they’re great for. Take a look:

SANSI 36W LED Grow Light – Small Light With A Purpose

best led grow lights

This small Sansi 36 watt LED grow light bulb is great for several purposes. If you need a grow light to add a bit more intensity to your current setup, or perhaps you have some small plants.

I can say from personal experience the Sansi 36w LED grow light bulb is one of the best cheap LED grow lights around for this purpose.

It satisfies all the requirements I named early on in the article – Light intensity, spectrum and coverage. I personally used this bulb to grow some succulents and a marigold (read my full experience here).

marigold

I flowered a beautiful marigold seedling picked from my yard, and also really brought my succulents to life. The succulents were previously under a 12w purple LED lamp which just wasn’t enough.

The white light spectrum plus infrared wavelengths makes is a nice full spectrum bulb compared to other cheap grow light bulbs that only contain a few wavelengths of color.

I’d say to keep this bulb 12-18 inches from your plants. Every plant will react differently so adjust accordingly.

It has a lifespan of around 50,000 hours as per manufacturer’s specification details on the product.

These Sansi grow light bulbs come with a generous 5 year warranty – no questions asked.

Pros and Cons of Sansi 36w LED grow light bulb

Pros:

  • Best Cheap LED grow light for one plant or use as a booster.
  • Best Red:Blue ratio.
  • Long lifespan.
  • Higher customer satisfaction.
  • A long warranty period.

Cons:

  • You’ll need to purchase a socket for the bulb.

If you’re a new grower and want to experiment in indoor growing, then this grow light bulb by Sansi is for you. In case you’re planning to use it as a supplementary grow light in larger grow space then also it’s a good grow light as far as you use it for blooming.

However, if you’re planning to grow in a space more than 9 sq.ft, then you should take a look at our reviews for best 600W LED Grow lights.

How do HPS grow lights compare to the best cheap LED grow lights?

You may have heard about HPS grow lights as well. They’re pretty inexpensive so if you’re in the market for a low cost grow light you may want to compare and contrast the two grow light types.

HPS grow lights perform better than the best cheap LED grow lights in terms of light intensity and even coverage area. The problem is they emit a lot of heat. So if you’re growing in a small enclosed space, HPS is definitely not the way to go in my opinion.

You’ll end up spending additional money buying fans and ducting for your grow tent which will ultimately make the project more expensive.

However, if you’re growing in an open space, an HPS light may be a strong competitor to the best cheap LED grow lights.

In terms of spectrum, the LED grow lights win. HPS lights will require changing bulbs for each phase of cannabis growth. In comparison, the best cheap LED grow lights emit spectrum that’s sufficient for all stages of plant growth.

If you’re interested in HPS lights – check out my article about them here.

The Bottom line for the Best Cheap LED Grow Lights:

When it comes to LED Grow lights, I always say you get what you pay for. But if you’re strapped for cash and you only plan to grow one plant, one of these above grow lights is probably your best bet.

Honorable mentions that weren’t mentioned above would be the Viparspectra VP series, Viparspectra Pro Series, and the Maxsisun grow lights. All affordable and good for growing one cannabis plant for the full life cycle.

FAQ:

What’s the best cheap LED grow light?

The best low cost grow lights are the Viparspectra V600, Bestva 1200w Reflector, Phlizon 1000 watt COB, or Parfactworks 1000w COB.

Are cheap LED grow lights good?

You get what you pay for when it comes to grow lights. However there are a few grow lights that offer good value for the low price. I recommend the Viparspectra V600, Bestva 1200w Reflector, Phlizon 1000 watt COB, or Parfactworks 1000w COB.

How much do grow lights cost to operate?

There are so many factors that affect grow light operating cost. Check out my grow light cost calculator to figure it out.

How much coverage can I get from a cheap LED grow light?

Cheap LED grow lights are entry level and don’t offer too much for the low price. The best models I recommended above will cover between 2 square feet and 3 square feet.

Which cheap LED grow lights should I avoid?

Avoid the cheap grow lights that have these features: – Emit less than 400 uMol, – Cover a small space like 1 square foot, – Have an unbalanced spectrum with only red or only blue color.You generally won’t find a good grow light for less than $100.
