There’s a reason I’m reviewing the Phlizon COB lights and not the Phlizon Newest LED grow lights.
And it’s simple: this series of lights is far better.
Yes, it costs more, but it gives you double the output and a far better spectrum for plants.
So why does every other site review the Phlizon Newest lights only (and rave about them)?
It’s because those lights have far more reviews on Amazon (mainly because they’ve been around longer).
You see, 99.9% of those review sites have never seen a grow light in real life and have no idea how one works. That becomes obvious very quickly, when you see them use sentences like: “this light puts out 2000 watts” (watts are not a measure of output).
But they review lights anyway, because when you click one of the links to go to Amazon and buy the light, they get a commission.
They choose lights with a lot of reviews, because it increases the chances you’ll actually buy the light. And they have no idea what distinguishes one light from another anyway.
Sometimes that means they review lights that are actually good. Sometimes it doesn’t. They don’t really know either way.
In both cases, they tell you the light is amazing. Because they want a commission.
But the Philizon Newest lights are not amazing. They’re ok.
The Phlizon COB series is another matter. They are the best low-budget COB lights currently on the market.
They are very similar to the Optic LED lights, but they cost less and give you more output. Let’s take a closer look at all five of their fixtures.
Phlizon COB Lights Comparison Table
Phlizon 2000W COB LED Grow Light Features
This review focuses on the 2000 for the specific numbers, but everything written here goes for the 1000 , 1500, 2500, and Phlizon 3000 COB lights as well.
- Uses 451 watts — save about 50% on your electric bill over HID lights
- Equivalent to a 800 watt HID system — but costs less to buy AND to operate
- Ideal spectrum for plants — the perfect light for all stages of growth, with peaks on red and blue and healthy amounts of all other colors (which is what plants need)
- 3.5 by 3.5 foot core coverage — effective coverage for plants with high light requirements; for other plants, it's closer to 4 by 4
- CREE COBs — high quality 50w COB LEDs provide both warm and cool full spectrum white light
- Supplemental Diodes — 10w diodes add the perfect amount of red, blue, UV, IR and white light to the two white COB spectra
- Dual switches — saves money, since you can turn off some of the diodes when you don't need full power
- Rated for 50,000 hours — 4-5 years with no bulb changes
- Great free extras — grow light glasses, thermometer and humidity monitor hangers, and adjustable rope ratchets
The two strongest points of the Phlizon COB lights are the high output and the perfect spectrum for plants. The coverage area is also good and I like that they give you a lot of free extras, although not all of them will be useful to everyone.
Output and Coverage
The output on this light is pretty incredible, especially when run at full power. It is about equal to a 800 watt HID system.
Dead center below the light, it gives you a PPFD of 2161 umol/m²s when hanging at 18 inches. That is double what any other so-called (more on the reason for the ‘so-called’ in the disadvantages section below) 2000w light can do.
This light is very similar to the much more expensive Optic 4, in that they both have 4 COBS surrounded by supplemental diodes. But this light costs about half as much and gives you more power.
It also gives you a larger effective coverage area of about 3.8 by 3.8 feet. It only uses 451 watts to provide this coverage and output.
Plus, you don’t have to run it at full power, which saves you money when you don’t need quite as much light intensity.
This light has two switches: one labeled “veg & bloom on” and one labeled “stronger on”. I like the switches, but hate the labels.
The “veg/bloom” switch toggles the 10w supplementary diodes and the “stronger” switch toggles the COBs. The names of the switches seem to suggest using the 10w diodes for veg and bloom and turning on the COBs only when you want more power.
That’s all backwards.
You’re much better off using the COBs as your base light, since they give you full-spectrum white light very similar to natural sunlight. I would use them during vegging, then turn one all lights during bloom to really boost yields.
That’s if you want to save money, by dialing back the power during vegging.
Personally, I would just run it full blast all the time. Why not take full advantage of the power. It doesn’t consume all that much electricity anyway.
The color spectrum is the other major strength of the Phlizon COB series of lights. Most LED manufacturers would have us believe that plants want only blue and red light, mainly because they want to sell us their blue and red light.
But that is not true.
While plants need more blue and red than any other colors, they also need a good amount of green and yellow light for maximum growth and yields (this article goes into detail on the light requirements of plants).
And that is exactly what the Phlizon Cree COB LED plant lights provide.
They feature 4 COBs: two emit a warm white light with a color temperature of 3000K (contains more red) and the other two emit a cool white light with a color temperature of 6000K (heavier in blue).
The COBs are supplemented by 10w diodes: 68 of them are red (660 and 630 nm), 10 of them are blue (470 nm), 6 are cool white (6500K), 4 are warm white (3000K), 4 are UV, and 4 are IR.
Together, they produce a color spectrum with peaks in the red and blue wavelengths and a good amount of light in between (orange, yellow and green). This is the perfect lights for plants and will take them through every stage of development.
Warranty, Return Policy And Extras
Phlizon give you a 2 year warranty and a 30 day money back guarantee. If you don’t like the light, you can return it. The fixture is rated for 50,000 hours, so you are unlikely to encounter problems during the warranty period.
When you buy this light, you also get a number of extras in addition to the light and the power cord. Included in the package are hangers, adjustable rope ratchets, grow room glasses and a thermometer and humidity meter.
The only major disadvantage is the same issue I have with all of the Chinese brands: misleading marketing.
Why do they call this a 2000 watt light?
Actually, I know the answer. It’s because every other Chinese brand that sells on Amazon lies about the wattage. They all feel like they have to, or their lights will get ignored.
For some reason, the majority of consumers see high wattage as the measure of a good light, when the best lights are actually the ones that manage to keep the wattage down, while getting the same output.
Wattage does not tell you how much light a fixture emits. It tells you how much power it consumes. Lower wattage means lower operating costs.
Sorry. Wattage rant over. Back to the point.
This light should not be called a 2000w light.
It does not use 2000 watts. Not even close. It uses 451w at full power.
If all the chips were driven at their maximum capacity, it would use 1160 watts. Still a far cry from 2000.
In terms of HID watts, it is equivalent to about 800.
So where does the 2000 figure come from?
Your guess is as good as mine.
All I know is it is very disappointing, because this is one of the best Chinese branded lights I’ve ever seen. It has a great spectrum and equals a 800 watt HID light in output while only using 451 watts.
And it costs very little. Yes, it costs more than the other “2000 watt” lights on the market, but it also gives you double the output of the next best one.
So, please, if anyone from Phlizon (or any other Chinese brands) ever reads my reviews: take this to heart. We do not want to see inflated wattage numbers. It’s actually a huge turn-off. We want lights that deliver high PPFD numbers (even in the corners of the coverage area, not just in the middle).
Phlizon Cree COB Series LED Grow Light Review: Final Verdict
The Phlizon COB lights beat any similar lights in terms of output and spectrum. They do cost a bit more, but the additional power and better results the spectrum will give you more than make up for that difference. It topped both my list of the best 2000w LEDs and of the best COB LEDs.
And even with the higher price, these lights are still priced far below top brands. They are even priced far below the top BUDGET brands, like Optic.
As mentioned, this light is roughly equivalent to the Optic 4, but costs half as much and actually delivers more output!
The 3000 watt Phlizon COB is equivalent to the Optic 6 and the 1000 watt model is equivalent to the Optic 2.
Of course, you need to be aware that you are not getting a 2000 watt light (or 3000 or 1000). You are getting a 451 watt light that is roughly equivalent to 800 HID watts. As long as you know that, you will be very happy with this light.
Personally, the misleading marketing really bothers me. But if you can get past that, you’ll be rewarded.
The Phlizon COB Series 2000w LED grow light (and its 1000w and 1500w little brothers and 2500w and 3000w big brothers) beat any similarly priced light. They also beat many more expensive lights. That’s why they earn a rating of 4.8 out of 5.
