Top Ten LED Grow Lights–another 2019 list.

Everyone wants to know an expert’s opinion of the the Top Ten LED Grow Lights in 2019.  There are a multitude of LED Grow Lights on the market at all price levels and with or without all the bells and whistles.  Sometimes the quality is what it should be but sometimes–well, some manufacturers cut corners to cut costs.  And the opinions about LED Grow Lights are just like belly-buttons–everybody has one.  So it can be hard or even impossible to find the lights that are best for your indoor garden.  Here is our take on why you should have LED Grow Lights and why we can help you find the best ones for your budget and your growing needs.

That’s where we come in–we do the work of sorting out what is good, what is worth the cost and even sometimes what to avoid completely.  Our Best 10 LED Grow Light Reviews for 2019 are posted on our front page.  But the fun doesn’t stop there–and neither do the LED Grow Light Reviews.  Our friends at LED Grow Lights Depot sell a wide variety of lights and growing products and they have put out their own Top Ten review for 2019.  Naturally it contains the products that they sell, but there is nothing against tooting your own horn.  They even produced a pretty slick video, which you can see below.  But if you are like me and prefer to get your information by reading, we have transcribed the important details from the Depot’s video and put it with our descriptions of their Top Ten LED Grow Lights.

Interestingly, even though LED Grow Lights’ video disparages sellers on Amazon, many of the lights in their list are also available on Amazon.

Here at , we don’t copy somebody else’s (unless it’s our own content on our brother site content but we certainly can comment on what someone else publishes. So here is a brief synopsis of the Top Ten LED Grow Lights as listed by the folks at LED Grow Lights Depot.

High Quality Quantum Boards in this LED grow light

Horticulture Lighting Group HLG 550 V2.

The first light on their list is also an Amazon Choice and has a 5-star rating. This light is made with high-quality Quantum Boards designed by Horticulture Lighting Group. This light is suitable for commercial operations as well as home use.  You can read more about Quantum Boards from MaryJane Farmer here under “DIY LED Grow Lights.”

Here’s what the Depot had to say about it: ” The Horticulture Lighting Group HLG 550 V2, released mid-2018, replaces a 1000-watt HPS and only draws 480 watts at the wall, while boasting a 2.5 micromole per joule efficacy. The fixture utilizes 1,152 top-in Samsung LM301B diodes while emitting a PPF of 1,178 micromoles per second across 4 custom-designed QB-288 quantum boards. These efficacy numbers make the HLG 550 V2 one of the most efficient LED grow lights on the market. The HLG 550 V2 is designed to flower a 4 foot by 4 foot area or veg a 6 foot by 6 foot area. The fixture is available in two spectrums: 3000K or 4000K.  The 3000K spectrum is ideal for full cycle growth, from seed to harvest, or for flowering only. The 4000K spectrum is best for keeping plants stout during veg and/or increasing quality during flower. The industry’s flagship unit is passively cooled, eliminating the use for cooling fans. The quantum boards sit on an anodized aluminum heat sink panel. The back of the panel contains a Meanwell HLG driver, dimmable down to about 240 watts via a built-in screw. At the end of 2018, the HLG 550 V2 was ETL CSA certified for commercial grows.

A good commercial LED grow light

Gavita Pro 1650e LED ML

The next light is Gavita’s top of the line and most powerful model.  Again, this is a good light for commercial operations but maybe a bit pricey for the smaller grower.  This light has a low profile, which would be useful in low-ceiling rooms or in vertically stacked multiple grow spaces.  The company claims that it’s multilayer LED construction allows a more uniform light distribution.

The retailer’s take on this Gavita light: . “The Gavita Pro 1650e LED ML released late 2018, is Gavita’s first LED grow light after solely specializing in HIT fixtures. The fixture replaces a 1000-watt double-ended HPS while only drawing just over 640 watts. The bar-style fixture contains a full spectrum, comprised of approximately 4000K white light diodes and 660 nanometer red. The Gavita LED grow light has a very large form factor, measuring 44 inches by 44 inches. This form factor creates an extremely even footprint throughout a 4 foot by 4 foot area.

Commercial Benefit of the Gavita

‘Commercial growers will benefit from the adapter and Gavita controller, which allows the Gavita LED grow light to be chained together and centrally controlled. The Gavita controller allows dimming down to 50%, on/off functionality, sunrise/sunset effects, and more. The fixture is UL listed for commercial applications. The Gavita LED is very comparable to the Fluence 2P. However, the Gavita LED is less expensive, it exudes a little bit more light, and it’s slightly more efficient. This is why we chose the Gavita over the Fluence 2P.’

NextLight is the next light in the top ten grow lights list

Nextlight Mega

The next light is in fact the NextLight Mega.  This is a 2016 design which has stood the test of time and is best for commercial operations.  It’s made in the USA and has a 5 year warranty.  It’s also sold on Amazon and it’s kind of pricey at $1525.50 but LED Grow Lights Depot offers a 15% discount at checkout.  Buy on

The details? “The Nextlight Mega, released May 2016, replaces a 1000-watt, double-ended HPS while only drawing 650 watts. The LED lifetime is rated at 100,000 hours, which is 20 years on a 12/12 cycle. The full spectrum, 3000K, 5000K white Samsung LM 561 B+ diodes are heavy in blue and green, while providing sufficient red for flowering. The Mega measures 37 inches by 37 inches and is passively cooled. No cooling fans. The wide form factor and thin profile allow the heat to dissipate without additional heat sensor fans. It also helps create a more even footprint without any hot spots or low PAR readings. The Nextlight Mega is available with a comport and dimmer for central communication and dimming capability. The unit is also daisy chainable to an additional fixture, which allows you to cut down the number of cords you need to run to the power supply. The Mega is designed and manufactured in the USA. This is a perfect fixture for tents, grow rooms, or commercial grows. The fixture is UL listed for commercial applications.

Research says this light grows better cannabis.

Optic LED Optic 8+.

Another pricey light but well worth it because of the high-quality Cree LED’s it sports is the Optic 8+.  The company claims that “Research shows significant increases in trichome density, volume & terpene profile.”

“The Optic LED Optic 8+ was released late 2017. This powerful LED grow light will cover a 4 foot by 4 foot area, or up to a 5 foot by 5 foot area with the 120 degree lens option, while only drawing 500 watts. There are three separate channels on the Optic 8+, veg, bloom, and bloom enhancer, all of which can be switched on or off and dimmed up and down independently. The Optic 8+ features 8 Cree CXB 3590 cobs and 32 3-watt diodes as a separate bloom enhancer channel. The bloom channel features additional UVA diodes, full spectrum white, 660 nanometer and 730 nanometer diodes.  While we do not have efficiency data for this fixture, we really like it because of the name-brand diodes, Meanwell drivers, and controllability, dimming plus spectrum control, of the fixture. These features, plus the PAR readings in a 4 foot by 4 foot area, indicate a solid fixture that will grow and flower with great results.”

Legalize Tomatoes (and cannabis) with Black Dog LED Grow Lights

Black Dog LED Phytomax-2 800

Moving to number 4 is another pricey choice, this one from the well-known Black Dog line of LED Grow Lights. These lights are also made in the USA and come from Amazon in a bundle that includes a “Legalize Tomatoes” sticker, good for those American backwater states where MaryJane is not welcome. (Check out MaryJane’s interactive Global Weed Infographic of US and world cannabis laws, soon to be updated with the 2018 Revolution.) Black Dog has several lights in various sizes with various add-ons.  Here are a couple of them.

More details on the Black Dog line:

“The Black Dog LED Phytomax-2 800 will replace more than a 1000-watt HPS with higher yields and better quality results while using less electricity. The Phytomax-2 800 utilizes 420 top-in 5-watt LEDS from industry leaders such as Cree and Osram, rated at 50,000 hours. The unit is advertised to cover up to a 6 foot by 6 foot for flower and veg a 7.5 foot by 7.5 foot area. However, for the best results, it is recommended to be used in a 4 foot by 4 foot to 5 foot by 5 foot flower area. The Black Dog LED’s phytogenesis spectrum can be used for both veg and flower, which helps reduce stalling associated with spectrum changes. The spectrum ranges from UVA to far red and includes a healthy amount of green to naturalize the light for easy viewing and to help increase photosynthesis inside the leaves and canopy.”

We know the Electric Sunshine from our interview with the inventor, Dan

The Green Sunshine Company Electric Sky 300.

Light number 5 is from our friend Dan at the Green Sunshine Company.  You can read MaryJane’s interview with Dan here.  This is a 2-pack set of ES300 lights which can be placed closer together or farther apart depending on your plant spacing.  The virtue of the Electric Sky is in its lensing system which reduces wasted light by directing more of the light straight down instead of losing it out to the sides. Again, not available on Amazon but you get a 5% discount on the two-pack at checkout on the Depot.

 The Green Sunshine Company Electric Sky 300, released mid-2017, contains a unique full spectrum that is heavy in wide-band red, which is red to far red that aids rapid growth and produces large flowers. The dual way linear lens, 60 degree by 120 degree, directs the light downwards towards your plants to reduce wasted light and increase PAR and vertical penetration. The modularity of the Electric Sky system allows you to spread the light over a large area for even coverage. Place 2 units closer together or farther apart, depending on the light intensity and coverage are that you’d like to achieve. The unit is passively cooled, and the driver is contained within the center of the grow light, making this one slick LED grow light. The ES 300 is ETL listed for commercial grows, and it measures 36 inches by 12 inches by 2.5 inches tall.”

Do It Yourself and save some bucks on a high quality LED Grow Light

Horticulture Lighting Group HLG-600H.

The next light is a DIY project which requires putting together the four Quantum Boards comprising the HLG 600.  The Depot calls this light its “best bang for the buck” light at $692.00. Buy on .  However, if you are handy with Do It Yourself projects requiring no more than a screwdriver and a wire stripper, you can save a ton of money by buying one or more of the same Quantum boards from Amazon. This light has several positive reviews raving about the light, about customer support from HLG and about the ease of assembly.  LED Grow Lights Depot also has a video showing how to put the light together.

“The Horticulture Lighting Group HLG-600H, released late 2017 and updated March 2019, is an affordable, but high-quality and powerful light engine for those who don’t mind a DIY project. This fixture can be put together in as little as 20 to 30 minutes. No soldering is required and features four QB 288 3000-Kelvin quantum boards in an Inventronics driver. A Bluetooth controller and scheduler is now available with this fixture, as of March 2019. There’s enough light emitted from this passively cooled fixture to cover up to a 5 foot by 5 foot flower footprint, with only 620 watts pulled from the wall. This is made possible by the high efficiency LM 301B Samsung chips. This DIY fixture will deliver the most amount of light for your money, while allowing you access to some of the highest-quality components on the market.”

Is this really the best bang for the buck?

MaryJane’s comment on whether this is “the best bang for the buck.”

MJ sez: It all comes down to how many bucks you have.  If you only have half as many bucks, then you might get enough


with the half-size version of this DIY kit from Amazon at half the price. 😉

Raging Kush for commercial cannabis growers with stacked grow boxes

Scynce LED Raging Kush

The Scynce LED Raging Kush light is aimed at the commercial market, particularly vertical grow operations (stacked tiers of plants) but small growers can certainly use it as well.  There are two unique features of this light: (1) a patented lensing system that spreads the light more evenly and reduces the central hot spot that some other lights have and (2) an Android app to control timing and spectrum.  The light is $1395.00 and is brand-new on the market so you might have to pre-order. For a 10% discount buy on “The Scynce LED Raging Kush, updated version released March 2019, is a game-changer in light distribution and uniformity. Ideal for flowering and vertical applications, the fixture can also be used outside of commercial grows and grow rooms and grow tents. The patented 120 degree lenses on the Raging Kush and other Scynce LED products remove the hotspot in the center of the footprint and distribute the light evenly over the entire footprint.  All of Scynce LED’s products can be controlled via their custom app. It’s an Android iOS application which allows you to manipulate the different spectrum channels, timing, and scheduling. The entire series is very well constructed and IP 66 waterproof. The Raging Kush measures 44 inches by 34.5 inches and is passively cooled. The series is UL listed for commercial grows.”

A commercial-grade LED Grow Light with a discount

California Lightworks Solarxtreme 1000

California Lightworks SolarXtreme 1000 is a new model from this well-known company and it is targeted to the home grower, without the remote control and other  functions that California Lightworks puts in its pricier commercial-grade lights.   The SolarXtreme 1000 is a powerful light with a heavy power consumption at 800 watts but its price of $899 takes some of the sting out of that.  It is sold as a plug-and-play light that can be set up in minutes by even the newest noob.

California Lightworks, a major manufacturer of high-end lights, has a fully stocked shop on Amazon, so their latest light is actually the SolarXtreme 1100 at $1799.  The model touted by LED Grow Lights Depot, the Solar Xtreme 1000, is about half that price at $899.  So if you don’t need the latest and greatest, check out the Amazon store and then maybe do your buying at the Depot.

“The California Lightworks Solarxtreme 1000, released late 2018, is perfect for the home grower who wants an affordable, yet powerful, plug and play option without any frills. Unlike California Lightworks flagship Solar System series, the Solarxtreme series does not integrate with the controller. All you need to do to operate it is plug it into a timer, and you are set to flower in up to a 5 foot by 5 foot area. The Solarxtreme 1000 uses driverless cobs that emit a full spectrum heavy and wide-band red in conjunction with far red, helps boost photosynthesis via the Emerson effect. The diodes are cooled by quiet, high efficiency cooling fans. The unit only weighs 22 pounds and is 18 inches by 18 inches, 120 volt application only.”

High Power light with a lower power consumption and another discount

Crecer Lighting Panthrx.

Here is another high-powered LED Grow Light suitable for any operation, the Crecer PanthrX.  It has a full spectrum with added red just like the California Lightworks light above and it has a similar power replacement profile, but draws about 200 fewer watts.  It has a connector to add dimmers for the high-quality Cree LEDs.   The Depot tested it in a 4×4 grow tent and reports a higher PAR value at the edges than other lights.  At $999 this is again a pricey light, but worth the price for the high power.   You can get a 7% discount if you buy on

The Depot says about this light:  “The Crecer Lighting Panthrx, released about mid-2018, replaces a 1000-watt HPS while only drawing 600 watts. The full spectrum is made up of name-brand Cree and Osram full-spectrum diodes covered by 90 degree secondary lenses. The diodes are passively cooled. Each of the two drivers contains dimming leads that allows you to install an optional dimmer, not included, on each side for full dimming capabilities. The Panthrx measures 30.5 by 20.3 inches and is passively cooled. We measured the PAR in a 4 x 4 tent and were extremely impressed with the PAR output and coverage and uniformity. The edges and corners were a lot higher than many of the other lights that we’ve tested. At 1305 micromoles per second and only $849, this fixture exudes a lot of light for your money. This fixture is ideal for tents, grow rooms, or commercial grows, and it’s ETL and CETL listed.”
