5 Best 1000W LED Grow Lights for Cannabis (2021 Buyer's Guide)

LED stands for light-emitting diodes. These lighting systems emits low heat, are turn-key , and can produce high yields with extreme energy efficiency. Prices for Best 1000w LED grow lights have rapidly come down in last few years, thus allowing home growers to switch towards them as their preferred lighting options.

When compared to HIDs, LED Lights don't require a reflector and ballast for operation, and can last for decades. HID bulbs will often need to be replaced every couple of years and aren't able to produce spectrum as LED lights.

If you keep the information written in the article in mind, you can easily go out to market and buy a LED Grow Lights, right? Hell No!.

For those who don’t know, Led Grow Lights come with several things you need to consider before you actually spend the hard earned money. They have different other type light as MH (metal halide) light and HPS (high pressure sodium) light.

The primary principle that LEDs operate on is electroluminescence. Discovered at the beginning of the twentieth century, this phenomenon has spanned many inventions but it wasn’t produced commercially before the seventies. Hewlett-Packard was the first company that started producing them in large scale and one of their biggest support lay in the researchers from Monsanto.

The color of the lights that LEDs emit is pretty much dependent on the type of material that was used for building a LED: ones with sapphire component would produce blue light, others that had a phosphorus component would shine white light etc. Initially, they were very expensive to produce, but following the Moore’s Law, the cost of producing LEDs was plummeting paired with their increased efficiency.

Well, pretty much everything that has to do with electronics. Groups of LEDs form a LED lamp. That means that if you have a certain number of LEDs in one space they make a lamp together, so it’s understandable why we use them for lighting. Whenever you were stuck on a crossroad, you spend your time staring at one LED lamp nervously waiting for the color switch.

That’s right,  traffic lights are actually LED lamps because of their penetrating power: they can be seen through the thickest of fogs. Why would you waste your money on some 19th-century technology such as incandescent light bulbs if you can have state of the art light system that your government has been using for quite a while?

LEDs also help you browse through channels. They are an integral part of any remote control system. Your remote is equipped with one and it is visible on the tip of your remote. Pretty much most of your home appliances have LEDs in them: digital clocks, oven, and fridge displays etc.

LEDs are essentially semiconductors meaning that they can selectively conduct electricity through a circuit. They consist of a power source and a P-N junction. P-N junction is essentially a small piece of silicone that has a positive(P) and negative(N) side. When electrons flow through a circuit they jump from the negative to the positive side and produce light in that process.

This is where high school physics comes in handy. We know that the average human being has mostly slept through physics classes so we are going to give you a crash course. Essentially, light color depends on the wavelength.

The longer the wavelength, the light will be dimmer. Now, white light pretty much consists of all the natural colors, but if you shoot that same white light through a prism, you will notice that natural colors from the light will divide itself. Red light is the light with the longest wavelength: between 620 and 645 nanometers.

The next one is a bright red or a dark orange color (depends on how you look at it) that has a range from 610 to 620 nanometers. After orange comes green that has a wavelength somewhere around 540 nanometers. Shortest wavelength is reserved for bright and dark blue at 500 and 480 nanometers respectively.

After talking about characteristics to look in a good LED Grow Light, lets talk about things to consider before buying the best LED Grow light.

1) Coverage Area: It's absolutely important to be aware of the amount of the space for your light coverage. It's imperative to understand the total amount of space needed cover with your LED lights. Each light has a range of space that it can cover, hence it's important to understand the accurate measurement of the grow space to cover. Once the accurate area for coverage by LED grow lights is found out, make sure to read the reviews and feedback from others on the actual space that the LED light can cover.

2) Brand/Budget/Price: These considerations are important depended upon your grow journey. For a beginner, it will make more sense to go with a lower priced option to get your your feet wet. This will be important as the higher-quality lights typically yield the best results. Once you are more experienced, it's never better to go with the higher-quality lights, as they typically yield the best results. A good brand that has raving customer reviews, is almost always, a safe bet.

3) Spectrum: A full spectrum LED grow light will go a long way in terms of helping your plant during various growth stage. Red,blue, infrared,ultraviolet all light variations are necessary, depending on the stage. It goes unsaid about importance of a powerful light, with different wave lengths to ensure maximum growth. The full spectrum yields are becoming popular these days as they run cool and don't need any additional fans, cost less overtime given the electrical savings, and a strong durability. We highly recommended to purchase these kind of LED grow light as they are the best lights offer that offer the full range, including UV light. 

4) Electrical Usage: A good LED lights will need to have durability and great electrical efficiency as well as they will ideally operating for at least 10-12 hours a day. When researching a good LED light, it's very important to understand what the total output is (1000w, 400w, 300w etc). The more powerful lights tends to have less electrical usage and more cost effective.

 5) Light Control: Every growth stage requires the proper amount of lighting (down to the exact hour). Please find below a breakdown of the phases below for growing LED lights:

• Seedling Phase: 16 hours on, 8 hours off


• Vegetative Phase: 18 hours on, 6 hours off


• Flowering Phase: 12 hours on, 12 hours off

It's extremely important that light cycles are followed to a tee as it can severely alter the growth and potency of your plants. 

A common grow light is basically made up of lights of two spectrums – red and blue. You can figure that out by looking at these lights as they emit a reddish-blueish hue and while many of them offer a fair mix of the two, you can figure out the dominant color in these lights if you look long enough. The process of photosynthesis happens perfectly between these two light spectrums and this is why most lights come with reds and blues. However, there’s more to plants than just photosynthesis and there’s more to grow lights than just the reds and blues. This is where full spectrum LED grow lights come into the picture! A full-spectrum LED grow light consists of all wavelengths including infrared and ultraviolet lights. Basically, the final output of the light here would be a white light.
