If you have been growing plants indoors for a long time, then artificial grow lights should not be something new to you. However, there are always complaints about the reliability of the lights or frustrations about the uncustomizable brightness for different growth stages. This is the case with HPS lights, or other old-fashioned bulbs.

For modern plant growers, LED lights should be the way to go. In this article, we are going to give you our take on the best 1000W LED grow lights for indoor gardening. Let’s get to it:


For people that have indoor gardens or grow tents for their planting hobbies, a reliable grow light is an essential investment. More than being a mere luxury or accessory, they help provide the ideal lighting condition to ensure optimal growth in your plants.

Maybe the natural light will be able to help you here and there, but what if you are in a place where the sun only comes out a few times a year? What if you want to take care of your plants during the winter? Without the necessary light available for photosynthesis, your plants will suffer from botanical problems. 

As for the reason why most modern plant growers choose LED lights for this purpose, it is simply because people cannot have enough good things to say about them. From having tremendously long lifespan, to consuming very little energy while still being able to deliver high quality light, LED grow lights can do it all. If you want your plants to thrive in a heat-free environment, LED lights can do that too.

These are also better for the environment in the sense that they do not break easily or contain toxic substances. For people who value environmental awareness, this should be a bonus.

Buying Guide

To get the best 1000W LED grow lights possible that can satisfy your indoor gardening needs, pay attention to these aspects:

Lighting output: This might sound a bit strange, but your 1000W LED grow lights do not necessarily consume 1000 watts of power to generate the desired lighting situation. The wattage number of 1000 refers to the wattage number of HPS lights that these LED lights are made to replace. In reality, LED lights will have no problems matching the lighting output of their alternatives without consuming as much energy.

The lighting output of your grow light will have a direct impact on the plants under it, so remember to be reasonable with your consideration to ensure optimal growth.

Energy-efficiency and actual wattage: Lower actual wattage will result in less energy being used to deliver the aforementioned lighting output. You will also need to change up the lighting intensity to cover different phases of growth. In this case, having a dimmable switch is extremely helpful and save you even more money in electricity costs.

Color: Contrary to popular belief, the reason why your LED grow light is equipped with multiple colors is not to decorate your indoor garden or tent. Although you can use it for that purpose, different colors will actually impact the growth of your plants in different ways.

Of course, while light will mimic the natural light well and let you effectively inspect your plants. However, it might not be as good for the plant during the vegetative phase as blue light, or during the flowering stage as red light. With that being said, set your priorities and match the color of the LED grow lights to your needs.

Coverage: For large indoor garden or wide grow tents, having the even lighting coverage means the world to your plants. By providing even amount of light on every single plant, you are creating an ideal environment for them to thrive in. 

You also have to make sure that the coverage of your LED grow light will cover the entire desired area to maximize its benefits. 

Cooling system: Any grow lights will generate excessive if used for prolonged periods of time. And although it is true that LED lights are better in this aspect, pushing them to the limits might not be a good idea.

If you plan to use your LED grow light a lot, just make sure that the unit has a cooling fan or heat sink built in to ventilate and release the heat culminated over time. A good heat management system will ensure no heat damage to your plants while prolonging the lifespan of your LED light.  

Spectrum: Customized spectrum features are all about giving you the convenience that you need when it comes to lighting for your plants. And if this is exactly what you are asking for, then look no further.

However, too many added features might even confuse you in the user experience. In this case, an LED grow light with minimal modes and features will benefit you more due to its simple operation.

How to look after your grow lights and prolong their lifespan?

Having the best possible LED grow light means nothing if you do not take care of it. To ensure that your unit will last long enough to offer all the benefits that you expected, proper care and maintenance is needed.

Here are what you can do to look after these LED grow lights:

  • Ensure proper installation, especially the wiring system

  • Perform regular cleaning and dust-removal tasks on your grow lights

  • Place your grow lights in areas that are moisture-free

What is the perfect distance (from the top of the plants) to set up your LED grow lights?

If you place your LED light units too far from the plants, they will not be able to deliver the lighting intensity needed for optimal growth. If you leave the light sources too close to the plants, serious problems like light bleaching can destroy them quickly.

For indoor plant growers, the sweet spot to set up LED grow lights is about 26-42 inches away from the plants.

Are LED grow lights easier and quicker to install than other alternatives?

Generally, grow lights are pretty simple to set up, especially if you have ready-to-go electrical outlets. However, since other options typically generate a lot of heat, external cooling and ventilation systems are needed. This makes the installation more difficult to get done.

More advanced LED grow lights come with these special features built-in, which makes them more convenient and easier to set up than other alternatives.

Do you have to use a ballast with LED grow lights?

For 1000W LED grow lights, there is no need to get a ballast involved – unlike other options like HPS or HID lights.

Why do LED grow lights require lower maintenance costs than other units?

LED lights are famous for their low maintenance costs, due to the fact that their lifespans are more superior than their counterparts’. In general, they should be able to deliver the same lighting capacity for 30000-50000 hours 

Other options always seem very promising at first, but degrade quickly as time goes by. This means that you would have to replace them way earlier before they have reached the expected number of running hours.

Final Thoughts

Lighting technology is on the rise and LED grow lights are an excellent variation of how modern technology can help with our daily tasks. Not only are they better at transferring energy into light, but they are also very effective at helping your plants reach optimal growth.

For the best 1000W LED grow lights, either GROWant OSRAM Full Spectrum with UV & IR LED Grow Lights or iPower GLLEDXA2300C LED Grow Light are guaranteed to keep your plants strong.
