Maxsisun LED Grow Lights – Overview & Comparison
Maxsisun released their new quantum style LED grow lights. These quantum board style grow lights are a nice upgrade from previous Maxsisun grow light models. There are three sizes available in the Maxsisun quantum grow light lineup: PB1000, PB1500, and PB2000.
The previous Maxsisun grow lights were a bit weak for growing cannabis unless you bought the more expensive models. The Maxisun quantum grow lights feature stronger light than the previous models, which makes these a much more attractive option for cannabis growers.
Let’s take a look at the specs on the Maxsisun quantum grow light lineup:

Which Phases of Cannabis Growth are the Maxsisun Quantum Grow Lights Good For?
Based on the specifications provided by Maxsisun as well as my own testing, you can use all Maxsisun quantum style grow lights to grow your cannabis from seedling to flowering phase.
Will these grow lights grow cannabis well?
Cannabis requires a minimum 300 micromoles of light during the vegetative phase and 460 micromoles of light during flowering. Technically yields will increase up to 1500 micromoles during flowering (see study cited below).
The Maxsisun quantum grow lights meet those light intensity requirements. All models will grow well during the vegetative phase, and decent yields during flowering.
The intensity on the PB1000 could definitely be stronger, but considering the cost of the Maxsisun quantum grow lights, I’d say they fall in line performance-wise. The PB1500 and PB2000 are strong enough to flower your cannabis plants well.
If you want a grow light with stronger intensity for flowering, consider my up to date list of the best LED grow lights for cannabis. It’ll likely cost you more than Maxsisun though.
You can read more about cannabis light requirements by reading my long article on the topic here. Let’s take a look at the rest of the design and specifications.
PB1000 (2×2 feet coverage):
P1500 (2×3 feet coverage)
PB2000 (2×4 feet coverage)
PB4000 (4×4 feet coverage)
The Maxsisun Quantum Grow Light Series includes three models – the PB1000, PB1500, and PB2000. They all look the same (see images above), but the higher number variants are each slightly longer and cover a slightly larger grow space.
The P1000 measures in at 12 inches long and 10.8 inches wide. The P1500 is about 15.5 inches long and 10.8 inches wide. The P2000 is 24 inches long and 11 inches wide.
The Maxsisun quantum board style lights don’t feature a heat sink, but grow lights of this low power consumption don’t make much heat anyway. These grow lights pull between 100 and 200 watts of electricity depending which size you choose. For that level of power I wouldn’t worry about heat generation, but the aluminum heat sink is there just in case.
Maxsisun quantum style grow lights don’t feature a dimming knob, which is somewhat inconvenient. Instead, you’ll need to calculate the correct hanging height for your grow light at each cannabis growth phase.
These grow lights use no-name SMD LEDs, if you’re looking for brand name parts you may want to consider the slightly more expensive Spider Farmer.
The light spectrum on the Maxsisun quantum grow light models is the same. It’s a white color spectrum consisting of 660nm (far red), 3500K (red), and 6500 (blue). This spectrum will grow your plants in all phases of growth.
I’ve not seen 6500K used on a grow light before, so that’s pretty interesting. Other grow lights use either 4000K or 5000K for their blue wavelengths.
It’s not much different than 4000K or 5000K. It’s just a different way of doing it. The one thing that disappoints me is the lack of infrared LEDs.
I haven’t seen any of the modern quantum style grow lights include ultraviolet wavelengths in the spectrum, like many of the purple spectrum and COB LED grow lights have. But a lot of them still include infrared which is beneficial to cannabis. So it’s disappointing to not see infrared included on the Maxsisun quantum grow lights.
As mentioned above, the PB1000 covers a 2×2 foot area, the PB1500 covers 2×3 feet, the PB2000 covers 2×4 feet.
These grow lights are not as strong as the others, so you can hang them much closer to your plants than you would with most other grow lights.
Looking at the Maxsisun PB1000 intensity map above, you can see at 12 inches above your plants the peak intensity is 700 micromoles, which is perfect for flowering. Most other grow lights would hang at 18 inches, so the PB1000 allows an extra 6 inches of space for your plants to grow.
During the seedling phase you’ll need to hang them at 20-22 inches, or use the dimmer. Ideally you’d want about 200-250 micromoles of intensity for seedlings.
Maxsisun Bud Quality:
Maxsisun grow lights have been around for a while, and are proven to grow respectable size colas when used properly. They’re a great piece to the high yield puzzle. Use Maxsisun grow lights in the proper environment, at the proper hang height and you should be seeing respectable yields for yourself!
How Do Maxsisun Quantum Grow Lights Compare To Similar Grow Lights?
There are so many grow lights on the market that it’s hard to make a decision. Most people I talk to just pick the model their friend has, pick an inexpensive model, and some take my advice on the best bang for your buck grow light models.
Most Similar Alternative – Viparspectra Pro Series
Comparing to the Viparspectra Pro Series and the King Plus UL series which are very similar in cost and design, the Maxsisun falls short in terms of features. The Maxsisun doesn’t offer a dimmer like Viparspectra Pro Series. In addition, there is no heat sink on the Maxsisun models, whereas the Viparspectra Pro Series includes one. Viparspectra grow lights are also priced lower.
Slightly Better Alternative – Mars Hydro and Spider Farmer
I think the smaller models (PB1000 and PB1500) have tough competition in the Mars Hydro TS-1000 (compares to Maxsisun PB1000), and the Spider Farmer SF-2000 (compares to Maxsisun PB2000). These two models compare the closest in terms of price and performance.
The Mars Hydro TS-1000 emits stronger light and includes infrared in the spectrum. At a very similar price to the Maxsisun PB1000, I’d probably take the Mars Hydro TS-1000. The TS-1000 will be a bit more frustrating to dim, but I would say that’s the only downside.
The Spider Farmer SF-2000 is considerably more expensive than the Maxsisun PB2000. But it also emits stronger light and includes infrared wavelengths in the spectrum. The Spider Farmer will be a bit tough to dim. So this is a more difficult choice, but I think if you can afford the Spider Farmer SF-2000 you should choose that one.
The larger model PB2000 offer more performance and I think these are solid competitors to other popular brands like Bestva and Phlizon.
My Final Opinion About Maxsisun Quantum Grow Lights:
Overall, the newly designed Maxsisun quantum grow lights are not bad. But they leave a bit to be desired. My main disappointment is that they are not dimmable. In addition, the spectrum could have included infrared wavelength.
With that said, if you choose one of these grow lights you’ll definitely be able to grow your cannabis without issue. They are strong enough for all phases of growth.
