01.3000 Watt led grow light yield

LED grow light is at a minimum as good as you would see with comparably HPS grow lights. If you use an ideal mix of red light and blue light for the plant development stage, you can actually double the grow light yield under 3000 Watt LEDs relative to what you’d see with HPS lights. You will also get more directional light, so there’s more energy directed at the plants. You may be able to avoid reflectors or simply brightening the entire room when your intention is nourishing an indoor vegetable garden.

What matters most is output in Lumens. HPS lights have about 100 Lumens per Watt, while good LEDs have an output of 100 Lumens per Watt. This has been improving over time and should continue to improve. However, this continual evolution of technology means that the efficiency and output of LED grow lights varies between brands.

The more important issue is the real output of the LED array. For example, there are 3000 Watt LED grow light panels that are advertised as putting out 3000 Watts, but they match 2000 Watt HPS lights. The fact that they consume 600 Watts of power is irrelevant when the light output is a third of what you expect. This is simply something you need to know when shopping for LED grow lights labeled as 3000 Watt models.

This means you have to be careful when selecting 3000 Watt LED grow lights to actually get the equivalent light output. Otherwise, your yields are lower than expected because you simply are not getting as much light as you thought you would.

02.3000 Watt led grow light coverage & power consumption

A 3000 watt LED grow light that matches the light output of a 2000 Watt HPS lamp will use 600 to 700 Watts of power. These grow lights tend to be put in a large panel, so it covers a large, rectangular grow area. In general, it would have 7.5 foot by 8 foot light coverage at a 24 inch height.

However, the grow area will depend on other design elements, as well. For example, a grow light with concentrators on them will have a lower coverage area, but it will deliver more light to plants in that coverage area. This means you need to read the technical specifications of every grow light you consider buying.

A general rule of thumb for determining how much power you need is to multiply the size of your growing area by 65 watts to determine the total number of watts you need for optimal output. If you have a 40 square foot growing area, then you need at least 2600 Watts of power coming from the grow light. This means you should use a 3000 Watt LED grow light, if its output is actually 3000 Watts.

The benefits of LED lights are that they turn on instantly, do not flicker, and create steady light that will not fade for years. They create focused light that is directed entirely on the plants. They are often dimmable.

Many models of 3000 watt grow lights allow you to switch between mostly red and mostly blue light or put out a full spectrum grow light. Note that if you switch to just red light, it isn’t going to be delivering 3000 Watts or the equivalent level of lumens to the plants.

Here are reviews for three of the best 3000 Watt LED grow lights on the market today.

Best 3000 Watt LED Grow Lights Reviews

01. 3000 Watt LED Grow Light, the King Plus by King LED


The King Plus grow light is designed to maximize photosynthetically active radiation or PAR output. This is due to its 300 10 Watt dual-chip LEDs. It uses Epistar brand LEDs. This grow light is ideal for the vegetative and flowering stages of plant growth. It should be on 12-14 hours a day for vegetative growth, 9-12 hours for flowering and fruiting plants depending on how much sun your plants love.

The King brand grow light is 26” x 15” x 6”. It has a roughly 8’ by 8’ coverage area or grow tent. They recommend the grow light be four to six feet above the plants. The grow light itself weights roughly sixteen pounds.

The expected lifespan for this LED grow light is 100,000 hours. The light output is equivalent to a 3000 Watt HPS grow lamp, but it only consumes 615 Watts of energy. It has several heat sinks and four relatively quiet fans. One point in its favor is how easy it is to use.

This LED grow light comes with a dual dimmer along with the standard on/off switch. You don’t need extra ballast for it to work. While it doesn’t have a timer, it can be controlled by many timer models available on the market. The King LED grow light also comes with a power cord and hanging hook that makes it easy to install.

Note that this system does put out UV and IR radiation, so don’t look at it directly when it is on. It isn’t water-proof, so don’t use it outside or let it get sprayed with water when irrigating your plants.

One downside of this LED grow light is that the LEDs do not have their own resistors. If one LED burns out, everything in the chain is burned out before you replace the LED. In short, if one LED burns out, the whole row dies. It can take time to get replacement panels when several rows of LED lights burn out. When one row or more burn out, the remaining LEDs remain bright, but they now burn out even faster. You don’t want this to be left unaddressed, since repeated failures can cause the unit to get very hot.


•Ease of use
•Comes with all the hardware
•Full-spectrum light
•Large coverage area


•When one light goes, the whole row goes
•Replacing lights is time-consuming

02.BESTVA Brand DC Series 3000 Watt LED Grow Light (B07DXT9162 )

The DC in the product name refers to their energy efficient dual-chip LED diodes. These are much more efficient and brighter than the conventional 3 and 5 Watt LEDs used in other grow light panels. They have the greatest PAR and Lumen output per LED of anything in this product class. These grow lights are so bright they can replace natural light.

The LEDs put out relatively little heat, but the unit has a powerful cooling fan system that keeps the panel cool. Yet the fans are rather quiet. Your grow light will not overheat your plants.

While it is advertised as a 3000 Watt LED grow light, it is about as bright as a 2000 Watt HPS grow light. The manufacturer says that it can cover an 8 foot square growing area or 64 square feet at a height of 24 inches. If you need to entirely replace natural sunlight and want to grow sun-loving plants, it may only cover a 30 square foot area effectively unless you are using reflectors and other ways to maximize the light.

The grow light is energy efficient. It uses about 600 Watts of power while putting out as much light as a 200 Watt HPS. This cuts your energy bill by two thirds.

One of the problems with this model is that the blue light diodes tend to go out. Nor is it easy to replace them without replacing the entire grow light panel. Another issue is longevity. In theory, LED lights will last 50,000 hours before burning out. These high efficiency light chips burn out far faster than that, and that is aside from the blue chips we have already mentioned. Monitor the fans, because if they go out, the heat will burn your plants.

03.Dimgogo Brand 3000 Watt LED Grow Light (B07JGMN2XF )


This 3000 watt LED grow light by Dimgogo is a rectangular grow light array filled with dual-chip Watt LEDs. A dual chip LED has two 5 Watt LEDs in every niche. Most of these are red light LEDS, while 40 of them are blue lights. There are also a few white and infrared LEDs. White LEDs are practical. They make it easier for you to see what you are doing. Infrared LEDs are more of a gimmick.

The plants rarely need that wavelength, and deep red light will not necessarily come from IR LEDs. Do not use IR LEDs as a selling point or expect it to keep the grow tent warm – your heaters or the heat output of the grow lights in general will do that. The greater issue is how much power the LEDs convert into light and how much waste heat they put out.

The LED grow light uses about 450 Watts of power. Moreover, unlike the first LED grow light on our list, it actually rivals the light output of a 2000-2500 Watt HPS light. Not as bright as advertised by the very name, but better than the Bestva grow lamp. This is the best 3000w led grow light for sun-loving plants as long as you are careful of grow light placement and condition.

This grow light has a tendency to develop cascading failures with the LED grow lights. If a few LEDs burn out, the rest will start to overheat in the circuit board and burn out themselves. You could end up with a nearly dark LED grow light within a few months of that happening if you aren’t able to replace the burned out LEDs soon enough. The problem is how hard it is to get authentic replacement parts or service to do this.

04.Phlizon Brand CREE COB Series 2000 Watt LED Plant Grow Light (B07MZ1QHKC )


The Philzon brand 3000 Watt LED grow light isn’t available through most retailers, but they are such a high quality brand that we’re recommending their 2000 Watt LED grow light instead. This 2000 Watt grow light requires only 450 watts of power. It is the most energy efficient LED grow light on our list.

One of the points in its favor is that you can switch between light profiles at the touch of a button. When the seedlings are germinating, use the veg and bloom button to create a mostly red light. When the plants are flowering, have the veg and bloom and stronger buttons both engaged to create a full spectrum grow light.

If you want to encourage stem growth, then use the stronger button alone to put out a mostly blue spectrum light. The grow light has a few infrared, ultraviolet and white LEDs in the mix, as well.

There are several points in favor of this model. Its superior circuitry and wiring are one. It does not suffer the burnouts of other grow lights on this list. There are not issues with overheating and cascading failures if a few LEDs do burn out. It has the long operational life you expect from LED grow lights.

If you need spare parts, the manufacturer makes those readily available. When you buy the grow light, you do not just get the grow light. You also get the hanging hardware, a temperature monitor, power cords and protective glasses you need to work with it. It is truly an all in one product.

05. 3000 Watt Full Spectrum, Dimmable LED Grow Light by Morsen

This Morsen brand full spectrum LED grow light has 236 red lights, 40 blue lights, 16 white lights, 4 infrared lights and four UV lights or 300 total. The broad spectrum light supports plants whether you are germinating seeds, growing seedlings, fostering vegetative growth or have flowering plants. This is the best 3000 Watt LED grow light for those who want to nurture their plants through every phase of their lifecycle. It comes with a single hanging hook and power cord.

The unit has six built-in cooling fans to prevent it from overheating. Between the isolated power connections and excellent cooling system, it won’t overheat even if a few lights have burned out to the point the rest of the board is overloading. This grow light’s fans are surprisingly quiet.
The unit is very energy efficient. It puts out as much light as a 3000 watt HPS grow light, but it only consumes 560 Watts.

The unit is 19” long by 13” wide by 4” thick. It weighs roughly 17 pounds. The coverage area is 6.5 feet squared.
The Morsen 3000 Watt grow light has an estimated life of 50,000 to 100,000 hours. In theory, this unit has a shorter operating life than the King Plus model.

The better reliability of the LEDs and its supporting electrical connections mean it will probably put out full light for its entire operational life. (Every LED has its own Zener diode, so one burning out won’t kill a whole row of lights.) On the flipside, the average life expectancy of each LED is shorter, so you’ll probably have a few burned out bulbs.

Because it puts out UV light, never look directly into the light bulbs even though the UV light bulbs look dim relative to the colored lights.

This grow light is not water-proof. Don’t put outside or splash it with water.


•Energy efficient
•One burned out bulb won’t turn off a whole row
•Easy to replace light bulbs
•Excellent heat dissipation


•Modest coverage area

.Not water proof.
