Best 400W LED Grow Lights For Your Indoor Growing

65% of the indoor growers regret bad grow light setup, resulting in terrible yield.

Hence, lightening up those notorious grow plants is a big nut to crack! Which, maybe bothering you up lately, and brought you to this web page.

LEDs are no doubt, a way better source of grow light from HIDs, HPSs, MHs, and so on. The best LED grow light comes with a fine blend of full-spectrum coverage, cost-effectiveness, and low heat emission. In case it gives you a promise of 50k+ hours of durability, that’s a jackpot!

But how on earth you’re going to pick up the right LED grow light? There’re 100s of them in the market, right?

That’s where we’ve taken over on behalf of you. We’ve hand-picked 154 of models in the market, and let real growers sort it out. Finally, a list of top 3 LED grow lights is there, with features and specs broken down in bite-size chunks.

What Are LED Grow Lights And Why Would You Want One?

LED grow lights are relative newcomers to the world of indoor horticulture, but they offer certain big advantages over the older styles of grow lights people have used traditionally.

The first big advantage is that LED lights run much cooler than more old-fashioned grow lights. While plants need a certain level of warmth to survive and thrive, old-style lights simply give off too much heat — much more than plants can absorb. This equates to wasted energy.

With LEDs, you are just creating the light that plants need without the extra heat, making them much more efficient.

As a result, LEDs are also much cheaper to run. If you run old-style grow lights that are constantly wasted energy as heat, you are using electricity for nothing. For this reason, LED lights can be an investment since they can end up saving you money on your electricity bill.
They have one other distinct advantage, too.

Light is emitted in a whole range of wavelengths, but not all light is useful to plants. The parts of the spectrum that are particularly important to plants are the red and blue wavelengths.

With many modern LED grow lights, they have been specially engineered to give out maximum amounts of light at exactly these wavelengths, essentially tuning them to the plants’ needs.

With regular grow lights, this isn’t possible, and the plants just have to take what they can from the full spectrum without being fed a special “diet” of red and blue.

Does Your LED Grow Light Provide a High PAR Value Rating?

Pay close attention to manufacturers’ recommended growing areas or you will run into trouble. In my tents I like to provide 3 square feet of space between each plant, that’s more than the average of 2 square feet. That means for every 36” square area I use for a plant the unit needs to be able to bloom and “veg” the same space.

You can “veg” a lot more plants under a light, but you need to be able to flower those plants and grow lights produce the most power directly under the unit. The actual blooming footprint is normally 20 to 25% smaller than the “Veg” footprint.

To grow and flower cannabis correctly you should provide the plant with 30 to 40 watts of light per square foot. So if your LED is 250 Watts you can have about 6 plants under it. This is a very simple way of looking at this situation since LED light isn’t really measured in Watts but in Par. Since lights are packaged with Watt ratings instead of PAR in most cases I choose to break it down this way for the readers.

Brand/Budget/Price: The more I test LED grow lights the more I’m surprised by the results I get from different manufacturers and price points. I recently tested a high-end brand light worth $799 USD against what most people would consider a cheap consumer-level brand that cost just $249 USD and the cheap brand kicked the big brand’s ass all the way around my grow tent.

You need to look at more than the price and the brand to determine the best LED grow light. You need to test it in a closed environment, growing cannabis to term and that’s just not possible for most people. That’s why you need to read professional reviews to know your way around.

Just don’t ever believe the hype unless it’s coming from actual users or professional independent reviews. Anything the manufacturer tells you will be incorrect and just marketing spin.

There are amazing lights that beginners can afford to start out with and there are high-end units that are worth every dollar you invest in them. Don’t get caught up in brand loyalty or thinking you must spend heavy to grow at home.

Light Spectrum: The kind of light a LED produces can be very different from one unit or maker to another. First off when we talk about the spectrum, we are talking about the light spectrums between 280 nm (UV) and 1200 nm (infrared). Each LED grow light is different but one thing they all have in common is that they all cover at least a small portion of the usable light spectrum.

Generally, cheaper lights produce fewer light spectrums. For example, the Mars Hydro II Pro which is a cheaper unit produces light between 390 nm and 690 nm and peaks in the blue and red spectrums. This is what gives the familiar purple haze that people are used to seeing.

More expensive units produce more light spectrums and intensity and, in many cases, produce much more product due to the inclusion of more plant usable light. These wideband lights produce light in every spectrum including UR and IR which are both helpful to the growth of cannabis plants.

Electricity Usage and Efficiency: LEDs or light-emitting diodes are 40% more efficient at converting electricity into usable energy than a traditional incandescent bulb. Bulbs are very wasteful and much of the energy is wasted as heat.

LED’s run much cooler then any HID light because they are efficient at converting power to light. What does this mean to you? It means that with each grow you saves 40% of your hydro bill, again and again. That’s why LED makes sense not to mention that it has an operational life of over 100,000 hours.

Light Control: Believe it or not there are many ways you can control your LED. When growing cannabis photoperiods are very important to the plants in determining when they begin to flower. Generally, I run my lights 24/7 in “veg” and then switch to 12/12 via a plugin timer.

Many traditional LED panels tend to provide a “veg” switch and a “bloom” switch which not only can control the time of photo exposure but also change the light spectrum to a more suitable mixture of light.

The last option is LEDs that contain a built-in timer. This is a nice to have feature but is easily replicated with a cheap plug timer.

Advances in LED grow lights Have Maximized PAR Value and Light Coverage

With the advances in LED grow lights, the time has come for this option of grow light. LED has transformed the way smaller growers can produce increased amounts of cannabis in smaller spaces. HPS lighting required more space due to the massive heat generated and required a proper ventilation system to dissipate all that heat.

That’s no longer true for those using LED lighting.

LED’s can function in a wide area of the light spectrum which means that your plants receive more usable energy from the light generated. LED is able to be adjusted to match the needs of your plants during the different life cycles of your grow.

The greatest change in LED lighting is that you will use less than 50% of the energy required to grow your cannabis while providing your plants with a better usable wavelength that promote better faster growth.

Checklist Before Buying a LED Grow Light

• Space Matters: Considering your space is a thing you should certainly do before buying a growing light. Space is a big factor. When choosing an LED growing light, its size and installation space must be properly checked in order to avoid the distorted growth of the indoor growing plant. Besides, when light is set too close to the growing plant, it will get destroyed and burnt. So, it is recommended to read the instruction manual to enable you to know the required distance of the light from the plant. Space and light’s size is key
• Quality: product quality is very crucial as it helps determine efficiency. So, before selecting a product always take note of its quality. Some of those things to consider while choosing the best grow light are its appearance, durability, and internal and external hitting issues.
• Pricing: price is a factor when it comes to getting a working and long-lasting LED grow light. Don’t need to bother with the price if you need quality. A good LED grows light for the large-scale purpose should be within the range of $500. However, for personal (hobby) use, you should spend $150–300.
• Appearance: The look of the product always gives the first impression and either calls for an attraction or repels. When a product isn’t eye-catching then no matter how beneficial it’s working, the grow light might not attract you. It is important to consider the out-look of Led grows light before buying.
• Durability: Durability is an indispensable factor to consider when buying an LED grow light. Knowing that a growing light is a big venture, which means you must embark on a sturdy product for greater efficiency and yield of your indoor growing plants. You can use a durable product for a long-living time. So, when selecting a grow light, take note of the longevity of it.
• Lifetime of LED: This is another important factor to know. Before selecting the best LED growing light for an indoor garden or greenhouse, the lifespan of the LED bulbs contained in the growing light must be properly checked and guaranteed.

Conclusion

One of the factors that you need to consider when choosing a grow light to use should be the wattage of the unit. Your grow light wattage will determine the size of your coverage area and how the light will affect the various cannabis grow stages.

A 400w grow light is highly efficient and does not consume a lot of power. It provides a sizeable coverage that you can increase by using more than one grow light in your grow tent. When growing cannabis, you need to get a lamp that will provide you with a full spectrum light.

It reduces the need for using more than one light in your grow room, saving you unnecessary costs. The light as well needs to be the right spectrum for each growth stage if you want to get the best yields.

Without meeting the precise requirements for your cannabis farm, you are setting up your plants to experience failure. We hope that the above 400W LED grow lights will make your job of choosing the right grow lamp for your farm.
