Best 1000 Watt Grow Light Reviews in 2019

So you’re interested in powerful LED grow lights. I’m about to go in-depth about what they are and how they’re used. I’ll explore what I think is the best 1000 watt grow light choice (spoiler: I like the King Plus). So generally, grow light is an electric light that emits an electromagnetic spectrum that is suitable for photosynthesis hence stimulating plants growth. In most cases grow lights are used for indoor urban farming projects, but that obviously includes growing marijuana due to the recent wave of legalization. In essence, grow lights solves two problems of indoor growing.

First, grow lights supplements sunlight. The other advantage is that grow lights can completely replace direct sunlight. They are designed to improve and optimize growth by providing specific spectra during the plant growth process. They simulate the sun to enable plants to grow naturally. Grow lights come in handy during winter or if you have an insufficient outdoor garden.

Plants require light for photosynthesis when growing. But plants do not absorb all the light. Even without sunlight the plant will grow if it receives proper light from blue and red light spectra.  Grow lights mimic the sun conditions including light, color and temperature.

In this guide, we review the best 1000 watt grow light in the market. We review LED-based and non-LED-based lighting. Let’s get started!

Best 1000 Watt LED Grow Lights

King Plus 1000w LED Grow Light

best led grow lights

Grow lights are ideal solutions for vegetative needs. Whether you are looking to supplement your houseplant lighting through the dark winter period, you need a consistent light source for starting a garden seed, or when planting a crop seed, grow light is the answer.

Most people understand the importance of investing in high quality LED grow light. King Plus 1000W LED is an effective affordable grow light. You do not have to go over your budget. Most growers choose to go for HID lights because LED is quite costly. However, King Plus cost less than HID systems and enables to enjoy low heat generation and energy consumption at less cost.

Full Spectrum

Kings Plus 1000W LED is an efficient and effective light that with both blue and red lights as wells s infrared and ultraviolet rays. It actually provides a full spectrum of light that plants require for growth at different stages. In addition, the pink or purple light that LED lights produce is good simulating natural sunlight that is essential to plants.  The ultraviolet lights promote cell division while the infrared light essentially disinfects the plants.

This grow light uses 10 watts diodes hence ensuring suitable PPFD values for 3 by 3 feet areas from 24 inches height.  King Plus 1000W LED spectrum is far much better than what you will get in other LEDs, fluorescents and Hid lamps.

Double Chips

A closer look into the King Plus 1000W LED you will notice that they are different from other grow lights. This is because unlike the standard diodes this LED grow lights are designed with a double chip. While standard grows, lights use 3W diodes King Plus use 5 watts diodes. You should therefore not use this grow light near the plants because it can kill your plants. Nevertheless, each diode uses Zener protectors to ensure the diodes are resistant to burning out and preventing the whole lamp from burning out when one single diode burns out.

King Plus 1000W cooling

The reason why LED makers do not push beyond 3 or 5 Watt is that a diode power past this would produce a lot of heat. It is therefore imperative that a grow light should have an effective cooling system. To deal with high heat input King plus comes with a smart cooling mechanism. The board is thicker than usual and has holes to increase heat dissipation. For better cooling, the two high-quality fans blow air over the heat sinks. These cooling techniques do not only increase the lifespan of the diodes but also significantly reduce the chance of burning out.


Depending on the size of your area you may need multiple lights. Yi will have to calculate how many Led units you will require.  King Plus Led light will effectively cover an area size of 3.4 feet by 3.8 feet.

Hanging Height

First, you do not have to worry about hanging your grow light. King plus comes with hanging hooks. Hence it is quite easy to suspend and adjust the light according to your preferred requirement. Well, you may need to do trial and error to arrive at an ideal height.  The general positioning though is between 1.2 and 2 meters from the canopy. It is, however, prudent to adjust this height according to your plant’s growth stage. For instance, during the cloning stage, it would be a bad idea to have you grow light near the canopy. However, it is a good idea to adjust your LED panel down to about 20 inches during the blooming phase given those plants requires a lot of light during this stage.

  • Reasonable price

  • Effective cooling system

  • Bright full spectrum diodes

  • 50,000 hour lifespan

What to consider when buying the best 1000 watt grow light?

Grow lights vary in features including prices, watts, sizes and type. According to your specifics, some may be better while others may be worse. There are many factors to consider before buying grow lights. Below is some of the most important consideration before setting out to purchase a grow light.


Chlorophyll I and chlorophyll II are the two primary compounds for active photosynthesis. These compounds absorb blue and red light. Nearly all the other light are reflected away from the plant. LED light Red light is more associated with flowering stage while blue is more associated with the vegging stage. Chlorophyll converts light energy into plant energy. LED lights have an edge in this process over to fluorescent and HID light. They convey the right energy more efficiently than HIDs.

To make a conclusive decision in regards to the spectrum you need to consider two things. The first is the color of the light in favor of white light. White grow light proponents argue that it is most natural and similar to sunlight.  Its light is similar in HPS and metal halide bulbs. White LED is the best option for grow lights. Plants look natural in a white plant, so it is very easy to inspect and sort our any discoloration. On the other hand, this light is made of green and yellow which are of little use to the plants.

Some grow light allows you to keep control of your spectrum.  The fundamental advantage is that this cuts the cost of electricity. Plants need more light during flowering as opposed to vegging. So you can reduce the amount of light. However, changing the color can shock the plants leading to stalling.

Wattage/ Light output

Grow light will have to operate between 10-11 hours each day which increases the electricity bills. A prudent choice can save you in the future by checking units of the total output. Higher outputs compensate for wattage loss. While the options go up to 1000 watt as you should not settle for 3000 W and below. LED provides more value compared to HID. A 250 watts LED grow light can produce the same light value as a 400-watt HPS. You should not use lumens to consider the light intensity because of that only works for human visibility and not plants. Note that no plant requires 24 hours of sunlight. So you may want an automatic timer that automatically rests from light to darkness.

Area coverage

It essential to all your plants get enough plants. You, therefore, need to measure the exact size of your garden. You should then find the lamp’s lighting area size. The rule of the thumb is that you need 32 watts per square foot. This requirement varies depending on plants.

Heat Output

Traditional grow light emits too much heat that is harmful to plants. LED plants are designed to emit low heat. Be sure to choose the grow light that emits suitable heat for your plants.


The price is one of the most important metrics to consider. The good news is that you have a whole lot of choice concerning the price. You can find very cheap CFL bulbs on Amazon. Fluorescent are also very affordable. HPS and LED green lights are on the pricier side compared to fluorescents. One thing that should always keep in your mind is that you should purchase from reputable vendors.

Other important features include canopy penetration, scalability, brand reputation, ease of use and using automatic timers.

Types of Indoor Grow Lights

There are several types of indoor grow lights that, though not as powerful as the sun, provide the required spectra to get the job done. The three major types if grow lights are

•    Light Emitting Diodes (LED)

•    High-Pressure Sodium (HPS) is also known as High-Intensity Discharge (HID)

•    Fluorescent Lights

Fluorescents Lights

They come in varying intensity. They last longer and more efficient than incandescent bulbs. However, they are less intense as HPS lights. The negative side of these lights is that the tubes require stands and light will require a ballast to regulate that current.

High-density Discharge

The demand for HPS lights has grown tremendously becoming more popular than fluorescents use. More experienced commercials growers tend to prefer these lights more. Since they emit more light and heat than most bulbs, they should be placed a greater distance from the plants.

Light Emitting Diodes

While they can be considerably more expensive than other bulbs, they are the most efficient. LED lights also last longer and consume less electricity. These grow lights are brighter, focused with zero or near zero heat production. You can even target specific wavelength within the color spectra hence getting customized lighting that can improve lighting over sunlight. However LED lights can be harmful to eyes and hence require protection when engaging in urban growing.

Why is 1000W better than other Wattage?

Watt is a measure used to refer to the amount of energy used by an electrical circuit. That means that 1000 watts bulb will be brighter than a 60 watts bulb. However, due to technological advancement, the quality of circuits varies from one manufacturer to another. Hence bulbs do not have the same quality. In other words, you can have two bulbs of 1000 W producing two different amounts of light.

The most important consideration in regards to wattage is the coverage area. 1000 watts grow lights will cover a large compared to let’s say 300 watts light. In addition, 1000 watts is more suitable for plants that require higher intensity compared to low wattage grow lights. Simply you should multiply the width and the length of your canopy to get the area. Now multiply the area by the wattage of your light. This is the wattage you need for optimal yields. In most cases, you will find that 1000 watts grow light to provide optimum light for most indoor gardens without being too less or superfluous.

Frequently Asked Questions about 1000 Watt Grow Lights

How Far to Position the 1000W Grow Light From the Plant?

There is no exact distance you can place you can hang your grow light. The hanging height is dependent on so many factors. More manufacturers provide the recommended height for their lights. Then adjust significantly if the light starts bleaching the leaves back it off some few inches.

If you do not have a recommended height from the manufacturer here are ideal distances. Note these are suitable heights for LED lights. For 200 watts hang the light 12-20 inches from the plant during the vegging stage and 8-16 inches during blooming.  For 600 watts the ideal height is 30-38 inches during the vegging stage and 18-30 during bloom. Lastly for 1000 watt grow lights the height should be 36 -46 inches for vegging stage and 21-36 inches for bloom stage.

 For 1000 watts HID grow light the distance should be 12-13 inches and HPS 12-35 inches. Fluorescent light is not as hot as LED lights. Hang it 4-6 inches above the plants during vegging and flowering. During seeding, 6-10 inches will be okay.

How to Take Care of the Grow Light?

LED grow lights are incredibly efficient and have a long lifespan. You can power strip that use surge protection to protect your LED grow lights wholly. To easily and conveniently protect your grow light keep them away from water to avoid accidents and short circuits. Similarly, avoid using the light in rooms with moisture to avoid being destroyed by water droplets. A power stabilizer also proves to be helpful. It ensures accurate heat and light for the growth of plants.


Grow lights are essential for indoor plants growing or if the weather is not conducive in the sense that there is not enough sunlight. However, before you purchase grow light ensures you have considered the cost and quality among other features. More importantly decide if you need fluorescent, HID or LED grow light. This article will help you make a shrewd choice. We are persuaded to believe that King plus 1000 LED grow light is the best 1000 watt grow light.
