Phlizon 600W LED Grow Light – Pictures, Specs, Opinions

Is the Phlizon 600w LED grow light a good grow light? Can you use Phlizon grow lights to grow cannabis?

The Phlizon 600w LED grow light is one of many 600 watt grow light models. This brand and model has particularly good customer feedback, and so I wrote a detailed review to help you determine if the Phlizon 600w is the best LED grow light for your grow space.

In short, I like these grow lights for seedlings and the vegetative phases of growth. This is a somewhat entry level LED grow light with modest coverage area and intensity.

If you’re interested in a more advanced light, Phlizon offers a lineup of stronger COB LED grow lights that are good for full cycle cannabis growth. They also recently released a bar-style LED grow light setup called the Linear Series.

Phlizon recently redesigned their 600W LED grow light to keep up with more modern design quantum style LED grow lights. Above are the two 600w models offered. The one on the left is the newer design.

For the sake of this article, I’ll be referring to the newer model as the older one will probably be phased out soon. But understand that the performance specifications of both models are pretty similar.

Phlizon is an established manufacturer of LED grow lights and associated products. Phlizon is backed with a huge R&D team which is the reason they’ve succeeded in creating a complete light packages for indoor growing.

Owner Comments:

Looking at reviews about this grow light over the internet, you’d derive that it’s a solid grow light, especially for the low entry price. The Phlizon Newest 600w LED grow light has garnered a high review rating at the time of writing.

A large majority of reviewers have rated this grow light in the top 20 percentile and had generally positive things to say. What are people saying more specifically? One happy owner mentioned it doesn’t produce any heat, and it’s very bright. Another said their plants love it and they’d recommend two of these in a 4×4 grow tent.

Of course there were minor complaints like the fact the delivery box was labeled with the product name. But it’s far from a major issue.

Now, let’s dive deep into its capability and performance features.

The build of this grow light is pretty solid, I owned a different light with this same style aluminum and it’s stronger than it looks.

The light uses Samsung LM301B LEDs. These are high quality LEDs. Phlizon made the board on this newer model IP65 waterproof, meaning the LEDs won’t be degraded in humid environments. In total there are 288 LEDs on this grow light.

Spectrum Quality:

Light spectrum quality is one of the most important aspects to consider while comparing the best 600W LED grow lights. Light spectrum is the critical factor responsible for how well your plants grow based on light penetration and color range.

The Phlizon Newest 600W contains a balanced mix of blue and red spectrum LEDs. As I mentioned before, the high performance Samsung LM301B diodes. The spectrum makeup is 3000K white, 6000K white and 660nm red diodes.

One unfortunate aspect is the lack of infrared or ultraviolet diodes, which are both beneficial for cannabis growth. Perhaps Phlizon will include those on a later version.


Light Intensity (PPFD) and Coverage Area:

Above you’ll see the light intensity chart for the Phlizon 600w Aluminum Hood design. Even though Phlizon says these measurements are strong enough for full cycle cannabis growth, I don’t agree at all. This light is only strong enough for seedlings and vegetative phase cannabis growth.

You can read my full article on light intensity here, where I explain why full cycle cannabis growth requires light 2-3 times stronger than what’s shown above. However this grow light is still strong enough for seedlings and vegetative growth as previously mentioned.

You can hang this grow light at 18 inches, or even slightly lower at 12-15 inches if you want stronger light. This grow light isn’t strong enough to burn your plants at the advertised intensity.

You can cover 2×2 feet with this grow light. So you’d need two of these grow lights for a 2×4 foot grow tent.

Power Efficiency

The Phlizon 600 watt grow light consumes just 100 watts while running at full power. That’s on par with other similar LED grow lights of this size and price.

This grow light also has a dimming feature, although it’s not really strong enough to require dimming. I do like the easy to turn knob compared to other grow lights that require turning a screwdriver inside the driver.

Heat Dissipation:

The aluminum hood is designed to dissipate heat efficiently. With that said a 100 watt light won’t generate much heat anyway, so you really don’t have to worry much unless you’re running three or more of these units in the same tent.

Price and Customer Service from Phlizon:

This grow light is priced competitively among 600w grow light options.

There is a low reported damage or failure rate with this product.

Moreover, even with lowest failure and damage rates Phlison offers a 2 year warranty to their customers.

That plus a 30 day money back guarantee where you can ask for a refund, and they’ll provide it without asking a single question.

Now, as we’ve covered all features in this Phlizon Newest 600W LED Grow Light Review, we think it is right time to look at its pros and cons.

I also put together an FAQ for your convenience:

Frequently Asked Questions:

If Budget isn’t an issue would you suggest this grow light?

  • My answer is both YES and NO. Yes because it’s a good light for new growers.

    No because if you’re not bound by a budget, the Mars Hydro 720W is better than Phlizon 600W Grow Light.

Why some LEDs are not working while light is ON?

  • It could be because of the inclusion of IR and UV diodes. These diodes emit light not visible to the human eye. It’s natural and you shouldn’t worry about it.

I’m planning to grow in 3’X3’ grow space, is it suitable for that space?

  • For a larger area, I’d suggest buying two units, OR a higher output variant in the same series which is the Phlizon 2000w COB

Why IR and UV are required? Is it so important to have?

  • Natural sunlight contains both IR and UV. UV exposure has shown to increase THC levels. Exposure to infrared has shown to increase the flowering process as well as flower density levels.

In terms of power efficiency, what should I keep in mind?

  • A light costing $50 upfront and sucking 200W for functioning is worse compared to a light costing $200 upfront and utilizing mere 100W for operation.

Should I consider some sort of certification on parts as a concern or an important aspect?

  • When you’re dealing with electrical appliances that generate heat, it’s reassuring to know they went through third party quality and safety checks. The last thing you want is a low quality untested item damaging your grow space.

My Verdict on Phlizon 600w:

The Phlizon 600 watt LED grow light is a decent grow light if you’re looking for an inexpensive grow light for seedlings and veg. It compares pretty well to other grow lights in the same price range.

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.
