That’s where the Chinese knock-offs come into play.
The best of them like Spider Farmer, cost quite a bit less. But they’re still imported and that drives up the cost.
If you go right to the source, you can find the same lights for even less. That means shopping on the Chinese website Alibaba.
Isn’t that risky?
Yes. There are hundreds of sellers. And most are not trustworthy.
How do you know which you can trust?
The truth is you don’t. You have to rely on others. And if you’ve done any reading on grow forums, etc. you’ll probably have come across the name Kingbrite.
The full name is Shenzhen Kingbrite Lighting Co and they have built a reputation as a trustworthy Chinese supplier on Alibaba.
They make every type of quantum board LED grow light you can imagine and their prices are lower than you will find anywhere else. More importantly, they have a track record of actually delivering quality lights.
Let’s take a closer look.

Kingbrite has far too many products to list them all here. To see their entire selection, do the following:
- Head to Alibaba
- Type Kingbrite into the search bar and change the dropdown next to the bar from ‘products’ to ‘suppliers’.
The table above contains only the most popular options from Kingbrite. It includes each size of light with 3000K white diodes, plus Epistar 660 nm red, UV and IR.
Each size light is also available with different color temperatures of white diodes (like 3500K, 4000K, etc.) and in versions that have only white light, or white light plus red diodes (but no UV and IR).
They also have more expensive versions that use CREE 660nm red diodes, instead of Epistar.
There are also a ton of kits you can build yourself and hundreds of spare components, like drivers or COBs or anything else.
You can buy everything you need to build your own lights completely from scratch. But the savings really aren’t worth it.
The best deals are the pre-built lights in this table, or the variations thereof.
Kingbrite V3 480W Samsung LM301H Review
This review focuses on the best-selling Kingbrite fixture the 480W Samsung LM301H quantum board fixture with Epistar 660 nm, UV and IR. It is basically the same as the HLG 600 V2 RSpec, except it also contains IR and UV. That said, Kingbrite also has versions without the UV and IR.
Everything written here about this light goes for all the other Kingbrite lights as well, apart from the individual specifications, of course.

Advantages
The strongest points of the Kingbrite series are that you get quantum board LED grow lights at a much lower price and that they have far more options than any other brand, in terms of sizes and light spectrum.
Low Price
Kingbrite sell quantum LED lights for a lower price than any brands you can find on Amazon. Far lower. You will have to pay for shipping to your country, but the costs are reasonable and even with the shipping added in, the lights are still the cheapest.
There are other sellers on Alibaba that sell similar lights for less. It’s usually only slightly less, so it’s probably not worth it to save that money.
The reason Kingbrite is better is that there are a lot of people on grow forums who have successfully bought their lights and had them shipped to the US, Canada and Europe. In other words: they have a track record of being reputable, which other sellers do not necessarily have.
Selection
As mentioned above, Kingbrite have a much larger selection of lights than any other brand that sell quantum fixtures. They have fixtures ranging from 65 watts to 600 watts. Whether you have a small grow space or a huge grow tent, they have fixtures to fill it with the light your plants need.
For each wattage, they offer versions with white light only, with white light and deep red (660 nm) diodes, and with white light, deep red, IR and UV. You can choose the color temperature of the white light (3000K, 3500K or 4000K) and you have the option of going with Epistar deep red, UV and IR diodes, or CREE XPE diodes. Naturally, CREE costs far more.
Kingbrite also offer a bunch of DIY kits and they sell all the parts separately, so you can build your own light without using a kit. You can save even more money this way, but the savings are not that big to be honest. The ready-made lights already sell for such a low price that it probably would not be worth it to DIY, unless that is something you enjoy or you have more time than money.
Spectrum
The light we are reviewing here uses quantum boards with Samsung LM301H white diodes and Epistar 660 nm (deep red), UV and IR diodes. You can choose between 3000K, 3500K or 4000K of the color temperature of the white light.
If you are using the light for all stages of growth, go with the 3500K or the 3000K. 3000K is best during bloom, but weakest for vegging. 4000K is best for vegging, but weakest for bloom. 3500K is a good compromise.
Nevertheless, I’d go with 3000K for full cycle. It might be the weakest during vegging, but it still does just fine. And the additional red spectrum light during bloom will help boost yields. To me, that is more important.
If you checkout Kingbrite’s entire selection (you can find their store by typing ‘Kingbrite’ in the Alibaba search bar at the top and changing it from ‘products’ to ‘suppliers’), you will notice many similar lights.
They need to whittle this selection down, because many are exactly the same. But there are also some that are different. You will see versions that do not have UV and IR and others that do not have the deep red either.
These are options you don’t really get with other brands. Most do not have UV and many do not have IR or even the deep red. The best choice is the one reviewed here that includes all three.
The other option you have is going with CREE XPE diodes, instead of Epistar, for the deep red, IR and UV light. CREE LEDs are much higher quality. They last longer and are more efficient, though the difference is not that huge. And they also cost a lot more. Since you are choosing Kingbrite because you want to save money, it probably does not make sense to splurge on CREE chips.
Coverage And Output
The biggest advantage of the quantum board style fixtures is the coverage, which is a function of their size. Where other types of fixtures generally have light emanating outward from the central fixture, quantum boards are much larger, so the light goes more directly downward.
Having a bunch of smaller diodes spread out over a much larger surface area, means the light can reach the canopy more quickly across a larger surface area. The end result is a more even light spread across the entire coverage area.
Take a look at the PPFD footprint for the Kingbrite 480W Epistar version with red, UV and IR across a 4 by 4 foot area at 20 inches and 40 inches from the plants.
Most lights might give you a much higher PPFD in the middle, but it drops off considerably toward the edges. That’s great for the plant directly beneath the light, but not so great for any other plants you might have.
The more even spread of the quantum board lights ensures that plants in the corners of the coverage area still get enough light to flower. Flowering plants need at least 100 umol/m²/s.
Other Advantages
Another advantage are the quality components. The light we’re looking at here uses a Meanwell driver, which is the best int he industry. It also uses Samsung quantum boards.
The Epistar diodes are great, but not the best. As mentioned, you can get a version that uses CREE diodes, for an additional cost.
The Kingbrite fixtures ship with 4 adjustable ratchet hangers, which is a nice touch. Many brands give you hanging brackets, but no rope ratchets. And you really want adjustable ratchet hangers. They make it so much easier to raise or lower the fixture, which you will have to do a lot as the plants grow.
One more advantage is the heat output. The smaller diodes spread out over a larger area means that passive cooling is enough. There is no need for loud fans. The fan noise in any grow room with other types of LED grow lights is pretty loud. Fans also tend to be the first component to break.
But don’t expect the light to be cool. These are powerful lights and they do emit a lot of heat. You will want to ventilate your grow space (this is something you want to do anyway, of course). But they emit less heat than the HID equivalent. Generally, it is about 30% less.
Disadvantages
The biggest disadvantage is that these lights come directly from China. They are only available on Alibaba, which means you have to use this website to place your order. The site has versions in many languages, so this is not difficult, but it’s not as easy as Amazon either.
Moreover, you will need to wait longer for the light to arrive from china. This usually takes 2-3 weeks. And if anything goes wrong with your light, it will take much longer to get it repaired or replaced. When the light arrives, you will have to do some minor assembly, like screwing the driver to the board and connecting it to the LEDs.
If you don’t want to deal with all of this, you’ll need to pay more and get a different brand from Amazon. Our rundown of the best LED grow lights will help you find the right light among the choices on Amazon. If includes several quantum style lights.
Continuing the same theme, the other major disadvantage is a shorter warranty. Whereas most brands on Amazon give you at least 3 years, Kingbrite only provides a one year warranty. Meanwell does guarantee their drivers for 5 years, though.
There is also no stated return policy, though customers on grow forums report that Kingbrite was good to deal with in cases where there were issues. I am not sure if they would allow you to return a light if you no longer want it, however. They said yes when I asked, but I never actually attempted to make a return.
Kingbrite HLG 600 V3 RSpec Equivalent LED Grow Light: Final Verdict
The Kingbrite Quantum Board LED Grow Light is a great alternative for those who want to get the best possible light for the lowest possible price.
You have a ton of options to choose from, including lights that are basically exactly the same as the hugely popular fixtures from HLG, but for a fraction of the price.
The components are good quality, the spectrum is perfect for plants (especially the one with the added deep red, UV and IR) and the lights are highly efficient to run. They deliver incredible output for a low power usage.
The only drawback is that they are only available on Alibaba. You have to order them directly from China. This ads some risk and is also a bit more work than simply buying from Amazon. But if you don’t mind that you are getting one of the best bargains you’ll ever find.
And Kingbrite is easily the best of the Alibaba suppliers. The only other one worth considering is Meijiu, but they have a smaller selection and there are some reports of issues with their customer service. Read our Meijiu review for more.
We took some points off because you have to buy direct from China, but the low cost and great track record still result is a high Grow Light Info rating of 4.7 out of 5.
Hey Steve, I’ve been going back and forth between getting HLG or Kingbrite and it looks like I’ll be going with Kingbrite after this write up. But I was wondering what you thought the best possible setup for an 8×8 or 10×10 tent would be? At first, I was going to go with 4 of the HGL 550/Kingbrite 480w, but then I thought I would get more if I went with 4 of the 600w instead so I was getting ready to make the purchase on those. But now I keep going back and forth after reading and researching and everyone says more less wattage lights is better for more even coverage and better yields. So I’m stuck and don’t know if I should get the 4 600w lights or go with 8 of the 320w instead to get more even lighting? I wanted to see what your thoughts were on this? Thanks!
It really depends if your tent is 8×8 or 10×10. That makes a big difference in the choice of lighting, as does the way you will arrange the plants in the tents (see the comment by Mackaronni below). Figure all that out first, and then you can choose the lights that best fit your setup.
First off good on you Steven for finally doing the KINGBRITES. Cant help but think I played a small part in your philizon threads 🤣
Second Jay I grow in a 8×8.
I only use a 4×8 section and a 4×4 section for plants. Leaveing the other 4×4 section for mixing nutes. Oscilating fans etc…. trust me if your plants are packed.tight u dont to save that 4×4 space to move around without going mental from bumping into shit.
I have the 480 watt kingbrite. A 240 watt. As well as 740 watts of cob led bars and 2×315 cmh lights. My coverage is stupid good.
If I were you
I would go with 480×3 but your coverage wont be perfect for all plants.
To fix that you could a. Bunch of the 360 watt boards (or 240 watt) if your looking to save money. And run those spread out for perfect par coverage by being able to position. Your lights advantageously.
And run
Yes, your comments were part of the reason I decided to finally take a look at some of the lights being sold on Alibaba. Kingbrite seemed like the best option, but I will probably also take a look at Meijiu, since they seem quite popular too. That said, I’ve already come across a few negative reports on their customer service in my preliminary research.
Kingbrite has amazing customer service. Jerry and vivi liu are top notch. I stayed away fromm Meiju because of the negative customer service reports
Hey steven, i bought 2 240w from kingbrite for my 1mx1mx2m tent. could u give the inches for each plant station ? veg and flower ? ty
I have 3 4′ x 12′ rolling benches to light. In winter I use 6 hps 1000w de each covering 4′ x 6′..
For the summer with kingbrite pcbs ( prefer lot of ventilation to a/c ) it seems that approximately 32 125w ( instead of 16 240w ) would maximize the overlap
effect on the perimeter of each 2′ x 2′. The around 5-6000cdn cost is cheaper than my friends
option of 6 spectrum king sk602 at 12000cdn—which are great lights. Any comments or alternatives before I order?
More smaller lights gives you more flexibility than fewer larger ones, so I’d probably go with that option too.
Which “version” compares to the Spider Farmer 2000?
If I’m growing vegetables (germination, starters, etc) which should I get? I’d probably have 20 plants (tomatoes /peppers/leafy greens)
Thanks
The 240w is comparable to the SF2000. If you’re only growing, not flowering, get the 4000K version.
i’ve bought 6 lights from them 2 240w, 3 480w bar style and 1 of the new 2020 water proof quantum boards.
the 2 240w i used for veg and seed making. the 1st 480w bar style i like so much i started to replace my other lights which is now complete. i’m using about 800w less power, the LEDs run much cooler so less AC which means a cheaper electric bill. a win win for my area. i purchased mine from the rep on instagram. she emailed me an invoice to pay and the lights get to Los Angeles in about 5-9 days.
I had no idea they even had a rep on Instagram. I thought it was just for posting photos.
Glad to hear it worked out for you Sean🙏 ans you like those lights as much as I do
@Sean do u have a link for the rep. 9 days is what I want
Say I did purchase one of the lights how far from the top of canopy do I place them cause I saw the PPFD testing above was for 18” and 36” what’s the best for full cycle like cutting 55”-60” veg 36” flower 12-18” is that about right? Say for a 240 or 320
Yeah, that sounds about right. I’d start at 18 (at least) for flower and gradually move it closer.
You can also leave at one height and use the dimmer.
Hey im looking for a light at kingbrite for a 2×4 tent too veg and flower with, i see a 320w 2020 waterproof board with
Samsung LM301H: 756pcs
CREE XP-E2 660nm: 36pcs,
CREE XP-E2 730nm: 12pcs
LG UV 395nm: 12pcs
My question is should i get this board or should i just not get the uv and ir is it even needed?? and just go with all cree somthing like this thanks.
320w
756pcs lm301h top bin chips
108pcs Cree XP-E2 660nm leds
You don’t need UV and IR, but there is some evidence it is beneficial. It really comes down to personal preference. Some people swear by it, while others thinks it’s useless.
New thing i just learned. UV light increases THC but reduces CBD.
So if you plan on growing medicinal cbd plants probably don’t need the UV. If your trying to get couchlock stoned and marathon SpongeBob square pants then sefinately get the UV
Great write up. It’d be nice to see an independent PPFD chart for these lights it seems the only one I can find is on their Alibaba page and after hearing about them using knock-off samsung diodes im a bit skeptical.
The only people that would say that they are knock off diodes are people who bought the identical HLG light for 3 times the price and they are jealous. Have a good day and buy a kingbrite.. I have 3 of the 2020 models.
Their not knockiff samsung diodes. Their 100% legit samsung diodes..
HLG uses top bin samsung diodes.
KINGBRITE uses medium bin diodes and were totally forthcoming when I asked them that very specific question.
Difference between a top bin and a medium bin lm301h diode is around d 7 to 10% efficiency.
Not worth the extra 800 bucks if you ask me.
The only one saying their knockoffs are HLG
Hlg tries to talk down kingbrite saying their knockoffs and their made in China.
HLG manufactures the fixture in America. But the diodes manufactured in Korea and China.
HLG is just sour that everyone’s caught onto their BS and so the fanboys are trying to spread rumors. Why don’t you head on over to 420magazine check out ‘MACKMURDER’ grow diaries. I gave about 7 of them. And you can see the beautiful plants grown under these kingbrites
Hey Steve im in Australia, my grow area is 24 foot x 3 foot. I’v been using 10 x 315 CMH lights but each draws around 350 to 360 watts, what do you recomend in the LED range ?
