KingLED Grow Light Review—Grow Light Features

PAR Output And Coverage

KingLED Grow Light PAR

One of the most important things to consider when it comes to investing in a grow light is the PAR value.

The 1000W KingLED grow light provides some decent numbers here: 2000 µmol/m2/s right in the center (when hung at a height of 12 inches).

As you can see above, it is quite a bit higher than some of its competitors.

KingLED credits this high PAR output to its optical condenser, which gathers scattered light.

This optical condenser works with the LEDs to provide high energy efficiency of 2.8 µmol/J. And it does all this while only consuming 145W of energy!

The manufacturer says the largest coverage area is 3.4 x 3.8 feet. This figure is probably a little generous if you want your plants to have more uniform coverage.

This light’s coverage area is best suited for 3 x 3 feet during the vegetative stage. During the flowering stage, it is more like 2.5 x 2.5.


The 1000W KingLED grow light uses 10W Epistar chips. These provide a lot of power for what is best described as an entry-level grow light.

Similar products typically use 3W or 5W LED chips, so these 10W diodes stand out among the competition.

Customers agree that these are among the brightest LED lights available for the cost.

The light from these 10W diodes can penetrate farther into the canopy than their 3W and even 5W counterparts.

Why don’t more grow light manufacturers spring for the 10W LEDs? The main reason has to do with heat output. The more powerful diodes typically give off more heat than the weaker ones.

Not all grow lights have a cooling system efficient enough to handle this extra heat.

Cooling System

To handle the added heat that emits from the 10W diodes, the KingLED grow light comes with a thick LED board with holes in it.

Their boards are about 3mm thick, in comparison to the 1.6mm boards used by some competitors.

This grow light also comes with several quiet internal fans and an aluminum heat sink. This goes one step further to help with heat dissipation.

That allows the lightbulb to work somewhere between 50 and 60 degrees Fahrenheit, which is a lower temperature range than other lamps, according to the manufacturer.

In case there are any powerful current flows, the LED lights are separated with their own resistances. This is to help avoid burnout.

KingLED Grow Light Cooling System

You can have peace of mind that your plants won’t burn with these cooling systems working together. This should help them in reaching their final stages of growth.

Effective cooling systems also help lengthen a grow light’s lifespan. That lifespan is about 50,000 hours plus with this unit.

That being said, some customers don’t seem to think the heat dissipation is all that great with this product. They claim that this unit gives off quite a bit of heat, thanks to the powerful LEDs.

This is not a hopeless situation. People have been successfully using exhaust fans in their grow tents and rooms to help with heat dissipation.

Full Light Spectrum

KingLED Grow Light Spectrum

KingLED has adjusted its spectrum, so the lights are a closer match to the ideal light conditions. This will allow you to grow plants in need of more light.

You get full-spectrum light from about 380nm to 780nm. This spectrum includes UV (which helps kill bacteria), as well as IR (especially good for plant growth and stem elongation).

This is a great range for growing plants that are capable of thriving under these lighting conditions.

KingLED Grow Light Modes

You can further customize the amount of light your plants are getting by using the veg and bloom modes.

The veg switch is ideal for the germination stage. The bloom switch is best during the flowering stage. Then, turn both modes on for the fruiting stage, for best results.

KingLED Grow Light Review: Customer Service

Good customer service can be a hard thing to come by when it comes to purchasing products online.

For the most part, this company doesn’t seem to disappoint its consumers.

The KingLED 1000W grow light comes with a 3-year warranty and free returns for 90 days. That is much better than the typical 30 days that you often see with similar products.

They also claim to get back to you within 24 hours, if you have any questions or problems. Their prompt and professional services have indeed pleased their customers.

What Are The Disadvantages?

KingLED Grow Light Package

There don’t seem to be any major disadvantages to the KingLED grow light.

The only issue we found is a lack of certain desirable features. For example, this unit is not waterproof, so it isn’t the best choice for outdoor grow tents or greenhouses.

They do have veg and bloom switches for lighting adjustments. But the lights, themselves, are not dimmable. So, if you really want to customize the lighting on your plants, you are better off with a different product.

For people with bigger gardens, it is important to note that these grow lights do not have a daisy chain feature. You can work your way around this by using a power splitter, but it is a bit of an inconvenience.

Finally, there is the potential heat issue, discussed before. Now, this doesn’t seem to be a big issue with every customer.

It may only be under certain circumstances that the unit seems to get too warm. Again, an extra exhaust fan should help with heat dissipation, if you find it to be an issue.

KingLED Grow Light Review: Final Thoughts

Overall, if you are thinking of purchasing a KingLED grow light, you will not be disappointed!

Yes, we have concentrated on the specs for the 1000W KingLED grow light in this article. The other grow lights in this series, the 600W and 1200W, both have the same features as the 1000W.

So, check out the other options if the only thing keeping you from buying this unit is the need for more or less power. You can check them out and see if they better suit your needs.

If you are looking for a grow light with a high PAR value, decent plant coverage, powerful and bright LEDs, full-spectrum coverage, AND good company-backed customer service, then it may be worth your while to invest in a KingLED grow light.

Some people may doubt the quality of these grow lights; they are a lot more affordable than many of the top brands. Rest assured, you are getting a good bang for your buck here.

No, it’s not perfect, but it is a great value—especially for beginner growers who are still figuring out what they are doing with their indoor plant garden.

At this price, why not give it a try?
