Phlizon Linear Series PH-2000 & PH-3000 LED Grow Lights – Specs & Comparison
Are Phlizon Linear Series LED grow lights good for growing cannabis? I take a look at the Phlizon PH-2000 and PH-3000 bar style grow light and compare the specifications to what you actually need to grow cannabis.
The Phlizon Linear Series PH-2000 and PH-3000 grow lights are a few models in the large Phlizon lineup. But this is the first bar or linear style grow light Phlizon has produced. Let’s see how it stacks up…
Which Phases of Cannabis Growth is the Linear Series PH-2000 Good For?
I recommend the PH-2000 grow light for seedlings and vegetative “veg” rooms. It all comes down to light intensity. Cannabis requires strong light to grow properly.
This light is definitely strong enough for seedlings and the veg phase as I mentioned, but the PH-2000 Linear Series isn’t great for the flowering phase of cannabis plants, unless maybe you use multiple units of this light in your grow area, at which point it becomes a bit cost inefficient.
Sure, somebody has probably bought one and flowered cannabis with it, but my point is that the intensity of this light will give you weak yields during the flowering phase.
Cannabis requires a minimum 460 micromoles of light during flowering, but technically yields will increase up to 1500 micromoles (see study cited below).
The PH-2000 only meets those specifications in a very small area of the canopy, roughly 1×1 foot, and therefore I wouldn’t recommend it for flowering. You can read more about cannabis light requirements by reading my long article on the topic here.
If you’re willing to consider the larger PH-3000 model, you can definitely flower cannabis with that one.
Aside from the light strength for flowering, I like everything else about the Phlizon Linear Series. Let’s take a look at the rest of the design and specifications.
Let’s be honest, this is a great looking grow light. It’s compact and features a large heat sink for heat dissipation.
One very unique feature compared to other grow lights is the IP65 waterproof rating. High humidity environments won’t degrade any of the parts over time. Take a look at the rest of the specifications:
|Dimensions:||23.5 x 3.5 x 5.7 inch||40 x 3.5 x 5.7 inch|
|Recommended Cannabis Coverage:||2×2 feet (seeds/veg)||2×4 feet|
|Watts Consumed:||240 watts||450 watts|
|Warranty:||3 years||3 years|
|Light Intensity:||200-800 micromoles (low-peak)||200-1100 micromoles (low-peak)|
|Where to buy:||Amazon||Amazon|
The Phlizon Linear Series PH-2000 provides a full white spectrum light, which has shown in peer reviewed studies to be 10-15% better for growing plants.
The spectrum on both the PH-2000 and the PH-3000 is comprised of 3000K white, 6000K white, and 660nm red LEDs. In total this makes up a nice full spectrum light that’s capable of growing all phases of cannabis growth if it’s strong enough.
The spectrum doesn’t contain infrared wavelengths, but infrared is used during the flowering phase which I already don’t recommend this grow light for.
Most LED manufacturers these days are easily able to isolate the correct spectrum of light, therefore unless you’re buying a really low quality LED grow light you probably don’t have to worry about light spectrum too much.

Based on the specifications provided by Phlizon, you can use this grow light in a 2×2 foot space. In a larger space than 2×2 feet the light intensity won’t be strong enough to grow cannabis.
How do the Phlizon PH-2000 and the PH-3000 Linear Series Compare To Competitors?
If you’re considering this grow light I imagine you’re either looking for a bar style LED grow light, or maybe a grow light for a 2×2 or 2×4 foot space.
In that case I think some of the closest modern competitors to this grow light are the Mars Hydro SP 250 and the Mars Hydro TSL-2000. I own the latter and wrote about my experience with it. In short, I like it a lot. Dont forget Phlizon also offers a more powerful line of COB LED grow lights.
But perhaps more importantly you need to consider the specifications of these two competing grow lights.
The Phlizon Linear Series and both Mars Hydro grow lights mentioned above are priced within a few dollars of each other. But my honest opinion is that the Mars Hydro versions have better specifications and offer a better deal.
The Mars Hydro SP 250 emits UV and infrared as part of the spectrum. Both of these wavelengths of light are beneficial to cannabis plants. In addition, the light intensity is notably stronger than the Phlizon 1000w Linear series.
The Mars Hydro TSL-2000 is in a similar position to the SP-250. You can read my full review of the TSL-2000 here.
In short, the light is strong enough for a 2x4ft space, and intense enough to flower your cannabis plants – all for a very similar price to the Phlizon Linear Series. It’s also dimmable and comes with extra cord length so you can detach the driver and keep it outside your grow tent, keeping temperatures low.

My Verdict for the Phlizon PH-2000 and PH-3000 Linear Series:
The Phlizon Linear Series PH-2000 appears to be a decent grow light for seedlings and the vegetative phases of growth. If you need a grow light for that specific purpose, this is probably a solid choice.
But if you’re looking for a grow light for full cycle cannabis growth, I’d consider the larger PH-3000 or one of the other competitors that I mentioned above. There’s better value available for full cycle LED grow lights.
What about for applications other than cannabis? If you’re looking to grow veggies this light may be able to get you through the entire growth cycle as fruits and vegetables require less light than cannabis.
If you’ve decided you want a grow light that’ll get you the maximum yield, I suggest taking a look at the high-end and mid-range grow lights on my home page. Those grow lights have considerably stronger performance and cover larger amounts of space.
Can the Phlizon Linear Series Grow Lights Grow Cannabis from Seedling to Flowering Phase?
The PH-2000 can be used for seedlings and during the vegetative phase of growth. The PH-3000 can be used for all phases of growth.
What height do I hang the Phlizon Linear Series Grow Lights?
For seedlings you should hang the lights 24 inches above the canopy. For the vegetative phase you should hang the lights 18 inches above the canopy.
What size grow space will the Phlizon Linear Series light?
The Phlizon PH-2000 Linear Series will light 2×2 feet. The PH-3000 will light 2×4 feet.
Does the Phlizon Linear Series grow lights include infrared?
