The Best Full Spectrum LED Indoor Grow Lights 2021

 What is a Full-Spectrum LED Grow Light?

A full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun. This marketing term comes from the concept of “full-spectrum light,” which in recent years has been used to refer to electromagnetic radiation from the UV to infrared wavebands.


The Benefits of Full Spectrum Light for Plants

Traditional LED arrays tend to only emit the spectrums that activate after the photorespiration period takes place ( grow lights with dominant red and blue LEDs). This is the reason traditional LED lights sometimes finish cycles with immature plants that produce low yields. By supplying plants with only the limited “beneficial” spectrums (pink light) from traditional LED arrays, you are essentially putting them into a permanent chill mode.

You may end up with some healthy plants, but they will not yield as much or be as healthy as plants under a full spectrum LED grow light. If red and blue light were truly all that plants needed then why do HPS lights which don’t have much of either color outperform them? The answer is intensity which plants go for first then spectrum. When you give your plants both intensity and full spectrum light they will pay you back every time. And if your budget is tight, you may find the best LED grow light for sale online.

What is a Quantum Board LED?

A quantum board led grow light is a newer alternative to the more expensive COB grow lights. The quantum board is a large circuit board in which a string of LEDs are connected forming “intelligent spectrum string” resulting in a broader spectrum and bigger plants. True full spectrum is the result.

Buyer’s Guide to Quantum Board LED Grow Lights

Here are some things that need to be kept in mind before you purchase a quantum board led grow light for growing your plants.

Heat Dissipation 

Quantum Board LED grow lights heat the least when you compare them with any other form of grow lights out there. Nonetheless, you must make sure that the heat dissipation is happening properly.  In case of these kind of grow lights, the heat sink must be of the right size and made out of the right materials so that all the heat leaves the body of the device and does not stay there and damage it. 

Design and Durability

You need to know that the grow light you are going to buy is going to be durable. One thing that lacks from most quantum board grow lights is durability. Considering that they are much thinner in size and are essentially just a board with LEDs on them, you need to handle them with care. 

Power Consumption

LED lights consumed lesser power than older forms of grow lights. Similarly, Quantum Board LED grow lights consume even lesser power than traditional SMD/COB LED grow lights. 

Coverage

You need to measure up your plants before you go out to buy a grow light. You must know the area that you want to cover – and then buy grow light(s) according to that. Sometimes it is better to buy two 2×2 grow lights than one 4×4 grow light (adjust to scale for your setup). So make sure the light(s) that you buy are sufficient to cover the whole of your setup.

Which LED grow light brands can be trusted?

This is a very short list, and is not in any way meant to be comprehensive. There are hundreds if not thousands of brands of LED grow lights, and a lot of them are great, but I’m only listing brands that I personally know for certain will work well for growing cannabis. These LED grow lights have actually been tested and given the seal of approval by real cannabis growers.

FAQ

Q. How long will my full spectrum LED grow light last?

A. Assuming a normal amount of usage, quality LED grow lights should last for at least ten years. Many manufacturers provide warranty coverage around this length of time, and some even offer a guarantee on parts, too.

Q. Will LED grow lights increase my electricity bill?

A. This depends — if you're used to running other kinds of grow lights, the LED version will actually reduce your electricity bill. If you're new to the world of grow lights then, yes, you will find a slight increase in power consumption. LED lights are, however, extremely energy efficient, so you'll probably find your electricity bill increases less than you might expect.

Q. What are double chip LED grow lights?

A. Double chip grow lights have two semiconductor chips per LED instead of one. This means they're twice as bright as a standard LED. If you only have a small growing space, double chip LED grow lights are probably overkill, but they're excellent for large growing spaces, as you get a more powerful unit without it being huge and unwieldy.
