This will be the 7th year that we’ve created a Best LED Grow Lights list, reviewing several lights in the process to tướng determine which lights would make the cut in the current years list.
In năm trước, I founded LED Grow Lights Depot, ví I have been in and around LED grow lights for over 9 years. LED Grow Lights Depot doesn’t represent just one brand, but actually 46 different brands. While this is not every single brand on the market, the companies we vì thế represent are the most popular players, offering quality grow lighting.
Before I get into the list, I would lượt thích to tướng mention a few things about how this list was put together.
The lights on this list include highly efficient and/or high light output lights with a good growing spectrum. Some are less expensive lights and provide an amazing bang for your buck. Don’t let the low prices scare you into thinking they are low quality fixtures.
All lights are from well-known established brands with good 5-year warranties.
The lights will cover a 4x4 to tướng 5x5 area. Lights that cover a smaller area are not featured. However, several of the brands in this đoạn Clip, make lights for smaller grow areas, ví I will briefly mention those when applicable.
This list does not contain every good light on the market. There are only 9 included here. Just because I don't mention a particular light, it doesn’t mean it is a bad light.
I have not been paid by any company on this list to tướng promote their lights. I am here to tướng give you my input based on my knowledge and experience of these brands or lights, their specs, performance, and customer feedback.
Let’s dive in to tướng the lights now!
Grow Light Science PROGROW 1800
Best light for the price
The ProGrow 1800 is an upgrade to tướng the former ProGrow 640. It is slightly more powerful and less expensive.
Expect a 673W power draw with a PPF of 1,821 PPF and PAR efficacy of 2.7 umol/J. Top-bin Samsung full-spectrum whites and Ledestar 660nm deep reds are used in the PROGROW 1800.
The light is dimmable via the included manual RJ-12 dimmer (connect up to tướng 3 units on one dimmer) or you can control the lights with Grow Light Science Command controller or most other 0-10V controllers on the market.
The driver is remote-mountable with the optional DC driver extension cable.
This light is ideal for the hobbyist all the way to tướng the commercial grower.
And the price is just outstanding, coming in at $420. You might be wondering if there is a catch. Well really, there is not. For a commercial-grade, DLC listed fixture with a 5 year warranty, you can’t go wrong! Grow Light Science is based in the USA.

Horticulture Lighting Group Scorpion Diablo
Best all-around fixture
The Scorpion Diablo was released late-2022 and is an update to tướng the former Scorpion Diablo. The light draws a bit more power and contains reflectors around the Quantum Bards which increases the light hitting the canopy by 10%, according to tướng HLG.
The Diablo still remains HLG's most powerful fixture at 2,121 umol/s and an efficacy of 2.97 umol/J, while drawing 715W. Expect intense 4x4 coverage or up to tướng 5x5 coverage at full intensity.
HLG is a bit secretive about the exact diode composition in their lights, but I vì thế know that they are using the latest LM301H full-spectrum EVO diodes, made by their horticulture partner, Samsung. They also use LM351H V2 660nm deep red diodes. HLG will always use the best diodes to tướng achieve the highest light output and efficacy.
The fixture contains QB648 Quantum boards, with nearly 4000 diodes across the fixture. Quantum Boards provide a good mix of uniformity and vertical canopy penetration.
The Diablos use Inventronics drivers. When purchasing this light, you have the option of a manual dimmer w/ an RJ control box or the GrowFlux wireless controller. It is also compatible with the Telos Growcast controller.
This light is designed and manufactured in the USA.
The Scorpion Diablo costs $1299. There is also another version of the Scorpion Diablo called Scorpion Diablo X, which I recommend for flowering only since this light contains a large bump in 660nm red. I also recommend checking out the lower priced Scorpion Rspec FR or HLG Blackbird.

Mammoth Lighting Mint 6-Bar
Best new light
The Mammoth Lighting Mint 6 bar hit the market late-2022.
The Mint series is a new line of Mammoth Fold-series lights using the Samsung LM301H EVO Mint diode. This diode peaks peaks at a 437nm, which is a shorter wavelength compared to tướng a conventional diode, and has been shown to tướng stimulate a plant’s secondary metabolites, suppresses microbial growth, and improve nutritional quality in edible plants (HLG also uses this diode in their Diablo boards).
The fixture also contains Samsung LM301B diodes and a nice blend of 660nm deep red and 730nm far red.
The Mint 6 bar draws 680W, emits a PPF of 2006, and has a PAR efficacy of 2.97. At this intensity, you can more than thở flower a 4x4 space.
Compared to tướng the Scoprion Diablo, the Mint 6 bar puts out a bit less light and draws fewer watts at the same PAR efficacy.
The light is fully dimmable via the manual dimmer connected to tướng the Inventronics driver or you can use the RJ connections for wired control. The driver is removable and can be mounted outside of the grow space.
There is also a more powerful version of the Mint 6 bar light, it is the Mint 8 bar. This fixture puts out 2613 umol/s of light and will cover a 5x5 area at really good intensity. CO2 is recommended when using the 8 bar in a 5x5 tent.
The Mint 6 bar is only $799, which is a steal given the high quality components and awesome specifications.

The Kind LED X750 has a light output of 1814 umol/S, efficacy of 2.5 umol/J, and draws 725 watts. Expect excellent 4'x4' coverage with this fixture.
The strongest feature of this light is the dual dimmable spectrum. One knob controls the main full spectrum spectrum and the other channel controls dhe Deep red, UV, and Far Red.
There are not too many lights on the market with this feature and you don't need a central controller to tướng gain access to tướng the spectrum control, lượt thích you vì thế for the ThinkGrow Model-H Plus.
However, there are only two dimmable channels, compared to tướng the Model-H Plus’ 4 channels.
Quality Osram and Philips diodes are used in the Kind LED X-series. The driver is removable on this light if you want to tướng move it outside the grow area.
The light costs $995. If you have a smaller area, consider the X420, X330, or X220.
PhotonTek XT 1000W CO2 Pro LED
Most powerful fixture
The XT 1000W an absolute beast! It puts out 2,925 umol/S of light which is enough light to tướng cover a 6'x6' area for flower, 5'x5' space if you are using CO2.
This fixture draws a true 1000W from the wall with a PAR efficacy of 2.9 umol/J.
PhotonTek uses top-bin white Lumileds and 600nm deep red Osram diodes across 10 magnetic bars. That’s right! The bars are magnetic ví if you ever need to tướng to swap them out, it is a quick job.
The spectrum is ideal for veg and flower, but really excels in flower due to tướng the high proportion of red.
The light can be hooked up to tướng the PhotonTek controller to tướng control timing, dimming, and more, for up to tướng 100 fixtures per controller. The driver is removable, but you need to tướng purchase the driver extension cables separately in order to tướng vì thế that.

This list is not exhaustive, but gives you some fail proof options and a good place to tướng start when looking for LED grow lights.
And to tướng reiterate, just because I didn’t mention a brand or light, it doesn’t mean it’s not a great light. There really are a lot to tướng chose from.
For example, ChilLED Tech makes high quality lights right here in the USA. There’s also Iluminar, who make a nice range of commercial grade fixtures, some with UV and IR. And AC Infinity lights are awesome, especially when integrated with their automated ecosystem.
If you are looking for something a little less expensive, kiểm tra out the popular Chinese brands lượt thích Medic Grow or Spider Farmer. I recommend that you stay away from Alibaba, eBay, and often Amazon for cheap LED grow lights. You just cant trust the specs, performance, and warranty for some of these lights and knock-offs.
