LED stands for light-emitting diodes. LED grow lights have come down in cost and home growers everywhere are beginning to make the switch to solely using them as their lighting alternative.
These lighting systems create extremely low heat, come ready to plug-and-play, and can produce high yields with unbelievable energy efficiency.
Whereas HIDs take a reflector and ballast for operation, LED lights don't. They could last for decades, whereas HID bulbs will frequently have to be replaced every year or two. But, among the principal reasons LED grow lights are considered the best is because of the spectrum they create.
Different Kinds Of LED Grow Lights
LED grow lights are available in different forms, so let us look at the pros and cons of each so you can find the Perfect LED light for you:
Panels are the most common sort of LED grow light and nearly all of our listing will consist of LED panels.
They include heatsinks for eliminating heat, a driver (think of it as a ballast), and frequently come with a guarantee.
When you think of LED grow lights, you're most likely thinking of an LED panel, because these are the only kind of LED really acceptable for full-state growth.
The best LED grow lights have a uniform spectrum, so in case you have 4 plants under your light, they get the exact same spectrum.
We already touched on the spectrum a little, but it's important to emphasise that the ideal spectrum is made up of not just blue and red light, but also infrared (IR) and Ultraviolet (UV).
Full spectrum LEDs permit you to grow from seed to crop with the identical light, instead of having to replace bulbs or use different grow lights for veg/flower.
Generally speaking, LED grow lights are extremely efficient. However, the best LED grow lights tend to also be the most effective. Running at a high level, producing high power, and keeping up a very low cost to run is quite important.
Given the price of LED grow lights, they have to be regarded as an investment. Apparently, your investment should last you a long time for it to show a return.
Therefore, the ideal LED grow lights are dependable and durable, standing the test of time.
All the lights we'll be listing are from the most reputable brands and include some kind of warranty. This provides you with peace of mind once you buy, knowing you are protected.

What's The Significance of Full Spectrum?
Should the word even be used? Well, when a business decides to call their products a Full Spectrum Grow Light, they generally indicate that their product outputs a wide, continuous and significant light across many (if not all) of the PAR range. That's it. In actuality, remember this:"Full Spectrum" as a term, is just as dependable as the Grow Light manufacturer. It's by no means a certificate standard; whether industrial, legal or otherwise. The simple fact is: as of right now, LED grow light technology is shifting away from using particular bands and the business is focusing on providing the broadest possible spectrum. You can see this if you noticed that many reputable LED organizations are moving away from pink/purple lighting and substituting their LEDs with"white" chips.
These white chips are created by a phosphor-coating method, where the coating is deposited on the LED die. The precise shade or color temperature of white light generated is determined by the dominant wavelength of the blue LED and the composition of the phosphor. And the depth of the phosphor coating generates the variations in the color temperature of the diode. Alright! Now that we understand how today's top notch LED grow lights are created, we can discuss the"best spectrum". The ideal grow light is one which reproduces the spectrum of our sun, while allowing us to adjust the light intensity to our precise needs. This are the pinnacle of"Full Spectrum." For our intents and purposes, the Sun's radiation spectrum is quite evenly dispersed and peaks in wavelengths around the PAR spectrum.

Spectrum of Solar Radiation. Notice how the Irradiance peaks inside the PAR/Visible spectrum.
While plants can use some of the light wavelengths away from the PAR spectrum, the light that falls outside of the range is generally either too strong or too weak to be of primary use for photosynthesis.
For instance, with certain exceptions UV light is too destructive to be used to synthesize large molecules, and infrared on the other hand is relatively weak, and generates a whole lot of heat. By comparison, within the PAR range each photon contains only enough energy to excite the electrons of molecules without causing damage to the cell. So, how should the ideal spectrum be? How much of every colour do plants need? Fortunately, science has the answer. It turns out that a novel by McCree (1972) figured all this out for us and printed a graph like the following one:
To absorb light, plants utilize a somewhat primitive but highly effective version of our eyes, which we call pigments. The most abundant plant pigment is chlorophyll and it is most effectively utilised to catch the red and blue light. Aside from those, there are quite a few different pigments, such as carotenes and xanthophylls which harvest light in different wavelengths and pass it on to the photosynthetic process.
It needs to be pointed out that green light really penetrates deeper into the foliage inside than red light and can drive photosynthesis better. This is because the upper layer of the chloroplasts which contain chlorophyll gets saturated while yellow and green can penetrate deeper into the leaf tissue and also be mirrored around until absorbed by another chloroplast containing chlorophyll or by an accessory pigment.
Major Things To Consider
Now that you know the science behind complete spectrum LEDs, here are the main factors you will need to think about when you're deciding which to purchase.
Cost at the moment, full spectrum LED grow lights are costly. The costs of establishing a system which depends on those lights can be more costly than standard HPS or HID setups.
However, you will save yourself a whole lot of money in the long term because of the efficiency of LEDs vs. HID lighting. By way of instance, the average lifespan of a HPS bulb is approximately 10,000 hours. Compare this to some 50,000 hour lifespan for LEDs and you can see the cost savings you will accumulate over time.
You can run a complete spectrum LED installation for 15 YEARS until you want to look at replacing it. So, in summary: if you can afford the initial setup cost, you will thank yourself in the long term.
Size Many HID or CFL lighting setups are bulky and awkward. This is not always bad, but if you are trying to grow in a more compact area it can make it hard. Complete spectrum fixtures are rather small and do not require ballasts or reflectors, freeing up room on your grow kayak or grow space.
Heat Light and heat are forever intertwined. The warmth of your grow room is a crucial factor, and grow lights are among the greatest contributors to increasing temps. It's why grow room ventilation is so important.
Complete spectrum LED lights do not have this problem however. Some growers really have to heat their rooms unnaturally during colder months because of how low the heat output is from this sort of lighting. That means that if you are growing in a warmer climate, you won't need to worry about overheating your grow room.
When deciding what size grow light you need, consider how many plants you will need to cover. Moreover, if you are planning to move your light from place to place, you might want something lighter and mobile, whereas in the event that you know that it's going to remain put, which might not be as much of a factor. Also, think about the space in which you intend to place it and make certain there's space for it to operate securely rather than up against furniture, drapes, or other products.
There are 3 things you will need to know before starting: the light requirement of your plant(s), the sort of light you wish to use and the size of your grow area.
1. Light Requirement For the light requirement, you only have to know whether it's a high light condition or a low one.
Plants with a high light requirement are plants which blossom and/or bear fruit, such as berries, citrus, orchids, cannabis, etc.. Plants with a very low light requirement are ones which don't blossom, like lettuce or ginseng.
2. Type of Lighting if you're unsure which kind of lighting you want, go with fluorescent lights if you only have one (or two) plants and LED or CMH lights differently. I urge LED over CMH, since they're easier to use, they cost less to operate, the create less heat and they last longer.
3. Size of Growing Area If you don't know how big your grow area, measure it. Or gauge the plant(s). Or discover how big the plants you intend on growing get.
As soon as you have these three pieces of information, you're ready to start.
Scroll down and discover the sort of kind of lighting you intend to use below. Then follow the directions to work out the size of light you need and the number of lights you need, if more than one.
There are a variety of types of grow lights to take into account, from panels to ones that hang overhead or twist into a regular light fixture. The sort of plants you have, the amount of existing natural light, and where your plants are found can help you limit your choices.
Ease of use
From installation to keep them working correctly, some grow lights need more effort than others. Also consider how much sound a grow light makes, especially if it's likely to be put in a busy place.

By Coverage Area
If you know how big your grow space is (by way of instance, the size of your grow tent), it is simple to determine which light(s) will best pay it. These are the approximate maximum coverage areas for the most common wattages of MH and HPS bulbs:
150 watt: 2 x 2 feet (or 4 square feet)
250 watt: 2.5 x 2.5 ft (or 6.25 square feet)
400 watt: 3 x 3 ft (or 95 square feet)
600 watt: 4 x 4 ft (or 16 square feet)
1000 5: 5 x 5 ft (or 25 square feet)
From this, you should have the ability to find out which size light is right for you and how many you require.
All else being equal, 600 watt lights are the most efficient (meaning you get more output per watt of power used) and 1000 watt bulbs are second best, so you always need to determine if those will work for your space .
By way of instance, say you have a distance that's 10 by 20 feet, or 200 square feet. That's perfectly divisible by 4 (the 150 watt bulb) or 25 (the 1000 watt bulb).
That means, you can light the region with 50 bulbs of 150 watts each (200/4=50) or with 8 bulbs of 1000 watts each (200/25=8). The eight 1000 watt bulb alternative is much preferable.
Having said that, you might also light the area using 600 watt bulbs.
The region isn't perfectly divisible, but 200 divided by 16 gives you 12.5, so you'd just use 12 or 13 fittings and make them match.
In this case, however, I'd go with the 1000 watt alternative, since 8 of these perfectly cover the region.
1 thing to note: that is based on the most coverage areas for each bulb advantage.
That means that the amount of bulbs you decide necessary from this method are closer to the minimum light requirement for crops with high light requirements.
The following method makes that clear and gives you better results if you would like to provide your plants plenty of light to optimize returns.
Choosing the ideal full spectrum grow light is essential to get a greater growth of your indoor garden.
