Best Led Grow Lights Review

01. Spider Farmer Company’s Newest SF-2000 LED Grow Light

Check Price On amazon

Spider Farmer is a well-known LED grow light company. This is their latest SF-2000 LED grow light. The unit is a two foot by four foot grow light. That’s the footprint for flowering plants. If you want to support leafy plants, it can support a three foot by four foot growing area.

One point in favor of this unit is that it is dimmable. The LEDs are not just dimmable, but the unit comes with a dial controller so you can adjust it anywhere from zero to 100 percent. Other units require you to buy a separate dimmer or come up with a controller. That is separate from the on-off switch. This is the best led grow light for those who need precise control over light levels.

It uses energy efficient Samsung LEDs. The unit requires around 200 Watts. It uses half the power of a compatible HPS light. The units can be daisy chained with a network cable. The lights are bright, but it is a broad spectrum grow light. It doesn’t have a red-heavy spectrum required for some herbal plants.

The open grid panel maximizes airflow around the grow lights, allowing it to keep cool without noisy fans. Note that you do need good airflow around the grow light to keep it cool. It can overheat inside of a grow tent.

One issue with the design is the overall quality. The grow lights may sag in the middle if just hanging from the ceiling. The aluminum frame may warp if the unit gets too hot, too. The circuits may not be properly grounded, and if that happens, that creates a shock hazard.


  •  Energy efficiency
  • Naturally cooled
  • Can be daisy chained


  • Poor quality frame

02. King Plus Brand UL Series 2000W LED Grow Light

Check Price On amazon

This is another full spectrum grow light built around Samsung LED chips. This unit is very bright, though it is a full spectrum light. It provides a mix of red, blue, white and a little infrared light. This is good enough for most plants and sufficient for providing supplemental light to plants in a window garden.

The unit has an open metal frame to maximize airflow, eliminating the need for fans unless you need tight temperature control or have the unit running in a grow tent. If you have good ventilation around the plants, this lowers the energy requirements for the indoor growing operations. The unit needs roughly 230 watts of power.

The unit can operate in temperatures just below freezing and up to 113 degrees F. This makes it more heat tolerant than other grow lights. We’ll say it can cover a two foot by three foot area where you’re replacing sunlight altogether and a three foot by four foot area when providing supplemental light.

One point in favor of this model is safety. That’s demonstrated by the Underwriter’s Laboratory seal of approval.

Furthermore, the unit can be used almost right out of the box. It comes with simple rope and hanging hardware. The unit comes with the power box. The unit does not come with controllers. It is either on or off, unless you buy additional hardware to control the intensity or its timing. You do get a single six foot power cord.

We don’t think this unit can be safety daisy chained. The unit doesn’t have the option to switch from mostly red or blue spectrum like other King Plus grow lights.


  •  Safe to use
  •  Wide operating temperature range
  •  Quiet
  •  Comes with everything you need


  •  Can’t adjust light in any way

03. CREE Brand COB LED Grow Light 3000W, WILLS Brand Full Spectrum Grow Lamp

Check Price On amazon

This Wills brand grow lamp is listed as a 3000 watt grow lamp. It is not just a full spectrum grow light. Yet it only pulls about 620 watts of power.

One point in favor of this model is that it comes with everything you need out of the box. You don’t just get a hanging kit and power plug. You also get a thermometer / humidistat. Note that it is still your responsibility to monitor the temperature and turn things off, if you don’t have a separate timer or controller.

This unit has built in fans to help keep it cool. The metal housing has vents to help remove waste heat, too. This unit is the better choice for use in growing tents, if it has good ventilation.

This unit is unusual for being able to operate at nearly 100 percent humidity. That doesn’t mean you can spritz it with water or immerse it, but it won’t fail in a humid greenhouse or hanging over your aquarium.

You cannot switch between mostly red and blue spectrum light. The unit is heavier on blue than red light. One issue with the unit is the short operational life of the LEDs. They may start burning out after just a few weeks of continual use. And you can’t really replace the bulbs.

The coverage area is not as good as you’d expect. It covers a 2.5 x 2.5 foot or 3 x 3 rea, not the promised 4×4 area.


  •  Everything you need out of the box
  •  High light output
  •  Water resistant


  •  Smaller effective coverage area than advertised
  •  Lights tend to burn out

04. Aglex Brand COB LED Grow Light 3000 Watt

Check Price On amazon

This grow light has a large coverage area, up to 4.5 x 4.5 feet. It has a 3000 watt full spectrum grow light, too. It has a mix of red, blue, white and infrared light to foster plant growth at all stages. It even has light chips at a variety of red and blue wavelengths to provide a replica of natural sunlight.

It even has several UV bulbs. More importantly, the unit is relatively energy efficient. It only draws around 700 watts of power. This is the best led grow light for those who want to have a single grow light cover a whole tray of seedlings or half a dozen potted plants.

The unit comes with everyone you need. For example, you get the power cord and hanging kit. Note that you do need to wear safety glasses around this. Safety glasses are not included.

One issue with the grow light is that there is no controller. You can’t dim the lights. You can’t switch from mostly red to mostly blue light.

The light bulbs do not last as long as advertised. The manufacturer says they can last up to five years. You’ll be lucky to get one year of continual use out of it before bulbs start burning out, and they are not easily replaced.


  •  Large coverage area
  •  True full spectrum grow light


  •  Doesn’t last as long as expected

This is one of the best LED grow lights for indoor plants thanks to the many features that make it easy to use and highly effective. These features begin with the ability to dim the light depending on the type of plant you’re growing and what stage of growth it’s in.

This dimmer is made with red, white, and blue lights that offer precise control while still providing a nice balance of PAR and lumen light.

While the design of this unit may be a bit bigger than others, that’s due to its high-quality design that begins with 3.2″ front-fans you can see right next to the lights. These are complemented by aluminum cooling heat sinks that dissipate heat quietly for enjoyable operation. You’ll also notice this light has three separate buttons that control the brightness, each of which is easy to use.

If you’re worried about power consumption, this light has you covered. With 400W of power, you might be concerned about your electricity bills. Fortunately, this light only draws 210W of power maximum, so you don’t have to worry about increased bills when your light is on for hours at a time.

If you have a growing area that’s no bigger than 3’x2.5′, then this is the light for you. It comes with a 3-year warranty and a 30-day satisfaction guarantee.

Choosing the Best LED Grow Lights

There are literally thousands of LED grow lights on the market. Quality and cost are only two of the factors you have to take into account. Furthermore, the other factors you need to evaluate for every potential grow light purchase affect your yield. Here is our recommendation regarding how to choose best led grow lights.

Type of Plants

What type of plants are you going to be growing? If you have sun-loving plants, it can be hard to get an LED grow light that provides enough light on the right color spectrum. If you’re providing supplemental light for a window garden, then you can use a general full-spectrum grow light.

Maximizing plant yield in an indoor garden may force you to buy intense grow lights with a broad spectrum or mostly red light. Leafy plants and flowering plants need more red light. Tall woody plants benefit from more blue light.

Once you know what type of plants you’ll be using with the grow lights, determine how many of the plants you want to maintain.

Growing Area

LED grow lights have a defined coverage area. For example, an 12 inch by 24 inch grow light may provide bright light for an area twice as large. If you’re providing supplemental light, you could hang it somewhat higher and cover 50 percent more space. But the first thing you need to know is how large the growing area will be.

Multiple the growing area required for each plant by the number of plants. That’s the area the grow lights must cover. If you have sun-loving plants or they need intense lights at critical phases of their development, plan on choosing grow lights that will cover that area with intense light. This means you’ll need to research the brightest coverage area (in lumens) that the grow light covers.

And you’ll need enough grow lights hanging near each other to cover the entire area without overlapping. This is because you don’t want to burn the plants with too much light.

The growing area should be somewhat smaller than the counter or grow tent that houses the plants. After all, you’ll need to be able to walk around the plants and they need space around the perimeter as well as between each other.

The best LED grow light will provide the right light intensity for your plants at the elevation you want to hang it. Always choose a grow light capable of producing more light over one that barely meets your needs.

Environmental Variables

Suppose you’ve identified half a dozen grow lights that can cover the necessary area. Now you will use to strike candidates from the list. Are you raising heat sensitive plants? Strike any grow lights from the list that generate a lot of waste heat. The heat might be managed with fans running on the grow light and good ventilation, but that increases the overall noise level.

If the grow tent will be located in your bedroom closet, you’ll want grow lights that have quiet fans or don’t require fans at all to remove waste heat. If you’re providing light for an aquaculture project or fish tank, LED grow lights that can withstand high humidity are worth paying a little extra for. The same is true if your plants need to be kept in a grow tent at high humidity.


Maintainability refers to how easy it is to maintain a grow light. One variation of this is repairability. How often do you have to replace the light bulbs or LEDs? The best LED grow lights rarely experience such burnouts, while traditional grow lights are easy to replace and have readily abundant spare parts. Built-in controllers and fuses are a bonus.

 Best led grow lights FAQ

01. Are LED Grow Lights worth it?

One of the most common questions potential buyers ask is: are they worth it? If you choose the right grow lights, the answer is yes. The grow lights need to produce enough light to either replace natural sunlight or supplement it, so that you get much higher yields than you would otherwise.

The best LED grow lights are far more energy efficient than HPS or incandescent light bulbs. In general, LED grow lights use a third to half as much power as traditional grow lights.

If you’re running the lights 12 or more hours a day, it is worth it to upgrade to LED grow lights once the current ones burn out. Choose the right model to meet the needs of your plant and minimize the total cost of ownership.

02. What lights do professional growers use?

Professional growers use LED grow lights that are not the brightest. They use grow lights that have a high PAR/Lumen output per watt. One such product is the Advanced Platinum Series P300 12-band LED Grow Light by Platinum LED. You get an incredibly bright light that needs relatively little power.

The compact grow light is rated as 300 watts but matches the power output of a 400 watt HPS light. It covers a roughly 3.5 x 4.5 foot area. The light has great penetration. You can run it with mostly red light, mostly blue light or a full spectrum light.

03. What’s the best light for flowering?

In this case, we would recommend Spider Farmer SF-2000 LED Grow Light, but only the 2022 version. It relies on a series of Samsung grow lights. It is controllable due to its Mean Well driver. It comes with a dimming knob. The unit consumes about 200 watts while putting out 2.7 umol per joule. This makes it very energy efficient, and it has good light penetration. It has a mix of red, blue and infrared light. The latter is good for plants in the flowering stage.

04. What type of light is best for growing plants indoors?

A full-spectrum LED grow light that puts out enough light to nourish your plants is ideal. LED grow lights are relatively cheap compared to light emitting ceramics, though LECs use slightly less energy. LEDs are rugged and durable.

The best LED grow lights will work for years, and they won’t shatter if you accidentally hit the grow light while working. They typically don’t generate a lot of waste heat, either. We’d recommend using LED bulbs for growing plants instead of standard LED lights. The grow lights are designed to generate light at the exact frequencies your plants need.

05. How far should LED grow lights be from plants?

This depends on the type of plants you are raising and the power of the grow light. In general, a 200 watt LED grow light should be 12 to 20 inches from growing seedlings and leafy plants and 8 to 16 inches from booming plants. A 400 watt grow light should be 13 to 20 inches from blooming plants and 20 to 28 inches from vegetation growth. Look at the PAR chart for your grow light relative to what you’re growing so that you don’t accidentally sunburn your plants.

Note that you should never put the grow light within six inches of the plant due to the risk of sunburn. And don’t elevate the light until it covers a large area regardless of what the plants need, unless you’re willing to risk wilting plants.

06. Are Chinese LED grow lights good?

This depends more on the make and model than anything else. There are Chinese LED grow lights that experience shorts and burned out bulbs within weeks of unboxing. And there are American grow lights that don’t do much better. The solution is to do your research and only buy quality LED grow lights, no matter where they are from.

07. What is the best LED grow light 2022?

KingLED is one of the major brands of LED grow lights. We would recommend the King Plus 2000 Watt Double Chips LED Grow Light. The double chips refer to the double LED chips connected to each circuit interface. This reduces power loss within the grow light and increases its energy efficiency.

The 2000 watt LED light uses as much power as a 1400 watt HPS bulb. This grow light puts out a full spectrum light including ultraviolet and infrared light. It runs cooler, too, so you’re unlikely to heat up a grow tent using this grow light.

08. Do LED grow lights really work?

Yes, they generally do. In order to “work”, you have to choose grow lights that provide the necessary light spectrum and intensity your plants need.

09. What led grow light should I buy?

Determine how much space your growing plants will need. Then choose a grow light that covers this area in the most intense part of the light footprint. If you’re growing more than a few plants, you should choose grow lights that can be daisy chained to minimize the number of cables you have to deal with.

10. How many lumens should a grow light be?

When you’re shopping for LED grow lights, lumens matter much more than watts. The best LED grow lights put out 3000 to 5000 lumens. A grow light with just 2000 lumens can only provide supplemental light for a window garden.

We don’t recommend using grow lights that put out 1000 lumens. While several of them together may be bright enough to nourish the plant, they have to be so close that it risks sun burning the plant or simply overheating it.

11. How many watts do I need for 4 plants?

For indoor grown vegetables like tomatoes and peppers, a 600 watt HPS grow light or equivalent LED lights will be sufficient. Make sure that the light output of the LED grow light matches the HPS light that is the benchmark.

You don’t want to use LED grow lights that only match the light output of a 300 watt HPS bulb because they labeled it 600. However, the LED grow light will probably be much more energy efficient. And it may only use 400 watts of power while matching the brightness of a 600 watt HPS.

12. How many watts do I need for 6 plants?

The best led grow lights FAQ give you concrete answers to your questions. And we’ll give you exactly that.

First determine how much space your plants require. The odds are that you’ll need at least a 5 foot by 5 foot area, since crowding the plants hurts them. Many vegetables do best with 20 to 30 watts of light per square foot. In this scenario, you’ll need somewhere between 400 and 600 watts of power to generate enough light. Choose a grow light at the upper end of the spectrum. However, you shouldn’t go too much higher because that raises the risk of bleaching and overheating.

A different issue is the light output of an LED grow light. Many models are listed as 1000 watts but only put out as much light as a 600 watt HPS bulb. These units would be sufficient for the scenario above, whereas a 1000 watt HPS bulb would hurt the plants.


The above led grow lights are the best led grow lights in 2022. We recommend you to buy these lights for your indoor lovely plants.
