What Exactly Are Full Spectrum Grow Lights?

You are probably wondering what sets full spectrum grow lights apart from other forms of lighting.

Well, there are two types of light in the world: visible and ultraviolet light.

The visible light you can see is made up of red, orange, green, yellow, blue, indigo, and violet lights.

Many bulb manufacturers focus on manufacturing lights that give visible light to make their customers happy, but the sun naturally emits light that you cannot see, which is known as ultraviolet light.

Even though ultraviolet light is invisible to the naked eye, plants require it to flourish and grow. Full spectrum increases light and harnesses the power of ultraviolet rays.

Although they are invisible to the naked eye, unlike conventional lights, full spectrum grow lights are a necessity for any indoor grow room.

Are Full Spectrum LED Lights Good For Plants?

In my fruitful years of indoor gardening, I've found that the best full spectrum grow light for me is the BESTVA Dual-Chip 2000W LED Grow Light because it creates the perfect balance of UV rays for plants from vegetative to flowering. Moreover, the high lumens output of this light guarantees perfect coverage.

Since I'm all for trying out new equipment to have several options, I've also discovered that the Apollo Horticulture GL60LED  is another smart choice because its lights are suitable to all phases of plant growth.


While these two provided the light I wanted, it may not produce the same results to you due to the different environment of your indoor grow area or types of plants.

This is why growers still have to know other full spectrum lights for indoor plant growth.

In the following parts, we'll look into the reasons why full spectrum lighting is essential for indoor plant growth, what factors you should consider before buying, and the best LED grow lights that expert indoor growers have tested.

Reasons to Use Full Spectrum Lighting 

Here are three things that you should know about full spectrum grow lights and why you should use them:

  • Plants grown using full spectrum lights reach much larger sizes and are ready to harvest faster.
  • The lights mimic the sun’s UV rays which not only reach plants easier but also are more readily absorbed by the foliage.
  • Unlike other types of grow lights, full spectrum lighting supplies the same power as the sun.

The Main Drawback of Full Spectrum Grow Lights

The only significant drawback to using full spectrum grow lights is the initial investment is expensive when compared with other lighting options.

Although it might be costlier, the lights still are the preferred choice by most indoor gardeners.

Control of the Indoor Growing Environment 

With an indoor grow system, you control your growing environment, so you are never tied to the seasons.

You can maintain a growth cycle throughout the year with lights.

Lighting lets you obtain a more bountiful harvest that often has great colors and flavors than outdoor growing.

What Exactly Are Full Spectrum LED Grow Lights?

The words ‘full spectrum’ refers to the grow light’s wavelength which is the color of light that a plant needs to photosynthesize successfully. Photosynthesis is the process that a plant uses to convert light into fuel for growth.

Plants are all different, so full spectrum lighting supplies wavelengths that range between 390 to 700 nano-moles.

The Light Spectra

There are two light spectra that you should familiarize yourself with:

  • The Absorption Spectrum: A plant can easily absorb and use these light wavelengths.
  • The Action Spectrum: This spectrum is extremely effective for a plant’s ability to photosynthesis and helps to drive the plant’s abilities.
absorption-spectrum_med

The absorption spectrum indicates the wavelengths of light absorbed

action-spectrum_med

The action spectrum indicates the overall rate of photosynthesis at each wavelength of light Source

A full spectrum grow light covers all the light spectra that a plant needs for growth. The lights can cover the absorption spectrum and control the ratio of wavelengths in the action spectrum.

The rays produced are all the light that your plant needs to flourish.

One of the critical benefits of full spectrum lighting is that it produces only the types of light that your plants will use to grow and wastes no energy-generating useless forms of view, so you'll conserve money on your energy bill.

The Perfect Spectrum

Many growers want to obtain the ‘perfect’ spectrum of light wavelengths for their plants, but this notion does not exist.

A full spectrum light offers all the main bands of color in the PAR (photosynthetically active radiation) spectrum. These are the wavelengths between 390 to 700nm. 

However, the exact wavelength does differ from manufacturer to manufacturer

. Also, the type of LED’s has an impact. Even the way that you set the light in your grow room will matter.

Some manufacturers also add infrared and ultraviolet wavelengths to their lighting. Also, some lights have been tailored for a full growth cycle, and others offer only during a plant’s vegetative growth or flowering state.

How to Measure the Range of Wavelengths and Light’s Intensity

This is a vital factor in buying a LED grow light. Most people think that it's all about watts per square foot or lumens.In reality, it involves PAR, PPFD, and to a lesser extent, PPFD or watt ratio.

Photosynthetically Active Radiation or PAR is the range for all the different colors or wavelengths of light that plants use for photosynthesis.

Your LED light should have all the different wavelengths or colors of light that make up PAR to ensure optimal plant growth.

Essentially, your full spectrum lights should have blue colors for the vegetative process and red/orange wavelengths for the flowering stage.

The right light will largely produce light that your plants will surely use for photosynthesis. As a result, little to no electricity goes to waste.

On the other hand, PPFD or Photosynthetic Photon Flux Density is one of the most critical metrics indoor growers should know.

It is a measurement of light intensity, and says how many light photons that fall within the PAR-range hit a given square meter per second.

Keep in mind that PPFD values in the red or wavelengths have the most effect on your yields in the flowering stage of your indoor plants.

LED Grow Light Buyer's Guide - How to Choose the Best LED Grow Light for your Plants

There are a few things that you should take into consideration before choosing full spectrum lighting.

You should take note of the following factors because some full spectrum lights can be used to certain growth stages while others can be used at any stage.

The potential size of the growing space 

First and foremost, you must identify the size of your indoor growing space because it determines the size and amount of full spectrum lights you need.

As a general rule, indoor growers use about 11 to 18 watts per square foot when growing low-light plants while high-light plants commonly require 32 watts of power per square foot.

Quality of light 

When rating a LED light, you must be aware of the range and ratio of different colors or wavelengths of light, as well as your light's efficiency and intensity.

Size 

HID and CFL lighting systems are bulky. However, full spectrum pictures are small and modular. They do not need reflectors or large ballasts which makes them a perfect choice for a small grow room or tent.

Watts Per Surface Area

Basically, it's advisable to get a full spectrum light for indoor plant growth that can produce a minimum of 50 watts per square foot.

For instance, a 2.5x2.5 ft space should at least have a 400W LED grow light while a 4x4 ft space must have a 900W LED grow light.

My 5x5 ft indoor growth space is being covered by a 1600W LED grow light.

Do LED Grow Lights Get Hot?

Grow lights increase the temperature in your grow room, but full spectrum LED lights do not emit excessive heat.

The lack of heat emitted by the lighting is ideal if your grow space is located in a warmer climate.

Meanwhile, a full spectrum light with higher heat output would burn out more quickly and will need to be replaced sooner.

Well-balanced low heat output LEDs emit less energy and have aluminum heat sinks.

Electricity Consumption and Output 

Your full spectrum lights will have to run for at least 10-12 hours on a daily basis, which then results in higher electricity bills.

The key is to check how many units is the total output of the light. Personally, I don't settle for anything less than 300 watts since there are models that could go as high as 1000 watts.

Consequently, a higher output helps compensate for any wattage loss.

LED light accessories 

Normally, full spectrum lights for indoor plant growth come with a hanging kit. If there's none, you'll have to manually turn on and off your lights.

So to save you the hassle, I suggest buying sturdy rope ratchets or a Honeywell Timer.

Is the cost of a LED Grow light worth the reward?

Undoubtedly, full spectrum LED grow lights are an expensive investment. The setup cost is typically far higher than standard HPS or HID setups.

Yet, over time, you will save money because the efficiency of LEDs far exceeds HID lighting.

Also, the average lifespan of an HPS bulb is only about 10,000 hours, but the lifespan of an LED is about 50,000 hours.

You will be able to run LED lights for at least 15 years before you must change lights.

This is why the Roleadro 1000W LED grow light also worked for me because it can run for up to 100,000 hours.

BEST BUILD QUALITY: King Plus 600W Full Spectrum LED Grow Light  

King Plus 600W grow light has full spectrum for vegetative and flowering stages: 410nm, 430-440nm, 450-475nm, 620-630nm, and 650-670nm.

With this power, you can have the most comprehensive spectrum to provide the needed light that is similar to the sunlight.

King Plus also made some chip upgrades, with the new dual chips 10W LEDs brighter than the traditional 3W and 5W.

The dual chips were also scientifically engineered to maintain the balance of the PAR Output and Coverage.

I suggest using this model if you have a coverage area of about 3x3 ft; although the height and lighting area are changeable due to different environments and plants.

I operate the light for about 12 to 14 hours during the vegetative stage, 9 to 12 during the flowering stage, and 7 to 8 during the fruiting stage.

As for my experience, it also works great on seedlings because it only produces minimal heat. In addition, I keep a 2 to 3.5 ft distance above the plants

King Plus 600W grow light also has an efficient cooling system because of its two high-speed quiet fans and upgraded aluminum heat sinks.

Thus, the feature keeps the lights quiet, cool, and work longer.

On the flipside, it doesn't create the same effect to a 5x5 growing area and there is no spot to daisy chain two lights together.

Nonetheless, King Plus 600W grow light is energy saving compared to traditional 600 Watt HPS/MH lamp.

It can also function at a working environment of 45% to 90% relative humidity.

Best 1000w Led Grow light: Roleadro LED Grow Light 2nd Generation Series

Roleadro's efforts have paid off after manufacturing a better spectrum light for growing and flowering plants.

  • 1x stainless steel hanger
  • 1x power cord
  • 1x use manual

Strikingly, this light can be used from germination to fruit stage. The full spectrum effectively promotes the synthesis of sugar for plants than the traditional red and blue growing lights.

My favorite thing about this is that the model has also applied the LED bead and zener design rather than a reflector to make sure the lights will work even if some of the LEDs fail to function.

The combination of 90 and 120-degree lenses maximize the light coverage

by creating strong light penetration.

Moreover, Roleadro 1000W LED grow lights include upgraded aluminum cooling heat sinks and advanced high-speed quiet fans that are useful for easy heat dissipation.

This is for indoor growers who want lights that have a less light loss, the lowest working temperature, and longer lifespan.

The model can provide much needed light to a 2x2 space during flowering and a 3x3 indoor grow space during vegetative state. It's actually perfect for beginners or those who only want a small grow.

Again, not all spectrum lights are perfect.

The main drawback of this model is that the lights are not water resistant while the blue lights are not good for your health.

Still, Roleadro 1000W LED grow lights are one of the most affordable full spectrum lights on the market.

It even comes with a double power cord used for power and daisy chain. As a result, two or more 1000W LED grow lights can be connected together with the standard included power cord.

Best For Indoor Plants: Apollo Horticulture GL60LED 180W LED Grow Light

This innovation from Apollo Horticulture comes with an easy to install LED grow lights, which emit considerably less heat and do not require ballasts.

As a result, Apollo Horticulture LEDs can be placed closer to the plant canopy, which is significant for healthy plant growth.

From what I've observed, Apollo Horticulture LED grow lights use just a fraction of the electricity than other types of grow lights.

Yet, they radiate minimal heat at about three-foot radius, which should not scorch your plants. The lights are also designed to withstand grow room temperatures of up to 131 degrees Fahrenheit.

This full spectrum light for indoor plant growth also comes with a stainless steel hanging kit, which is protected against corrosive effects arising from the moisture generated by the plant’s transpiration process.

Moreover, the hanging kit enables the lights to function in a wide humidity range of 0-95%.

What I especially love about this low power grow light is that it can cover a five square feet area of plants at the vegetative stage and serve a four square feet area of flowering plants. The LED view angle can also be adjusted up to 120 degrees.

Be prepared to face the setback that the lights are very bright compared to others, which means it has the tendency to impact plant growth indirectly.

Unfortunately, there is no proper sink for heat escape since there's no separate duct.

Still, Apollo Horticulture LED grow lights are suitable for all phases of plant growth and flowering.

The lights boast a lifespan of 50,000 hours

and a two-year warranty, giving grow tents, H2O systems, greenhouses, and hydroponic systems the best full spectrum lights they need.

In addition, Apollo Horticulture's lights do not give dangerous UV rays because of the different light spectra that are ideal for plant growth: 460nm, 610nm, 630nm, and 730nm.

Note that ultraviolet light is lower on the spectrum, 10-400nm.

Generally, products made by Apollo Horticulture remain cool even when operating continuously, which is helpful for small grow rooms capable of accommodating only one grow light.

Full Spectrum Lighting FAQ

Do I need full spectrum lights?

Full spectrum grow lighting is as close to natural sunlight as you can get without growing your plant outdoors.

What Type Of Grow Lights Should I Purchase?

There are several types of grow lights, so you are wondering what kind to buy.

The type you choose will depend on what you're developing and the amount of grow room space.

You can select from fluorescent light, LED lights, and HID lights (high-pressure sodium and metal halide). However, full spectrum LED lighting is considered the top-of-the-line choice.

WHY FULL SPECTRUM LIGHT

Is full spectrum lighting worth it? 

Yes, full spectrum lighting is initially expensive. However, the amount of money you save on energy consumption and bulb replacement is substantial.

Also, your plants will thank you.

Undoubtedly, plants grow better under full spectrum lighting.

From seedling to harvest, your plants will flourish.

Can you have a smaller grow room with full spectrum lighting?

Yes, full spectrum lighting requires far less space than other forms of grow lights because they produce extraordinarily little heat.

The reduced heat emissions mean plants can safely be placed close to the light source without worrying about the foliage sustaining damage.

Can you control the wavelength of the LEDs?

Yes, you can run LED lighting in your indoor grow space 24 hours per day. Most of the time, I adjust the red wavelength on most full spectrum lights to maximize the plant’s growth rate.

LED lighting allows indoor growers to harvest multiple plants in one season that are auto-flowering to maximize harvest. Thus, flowering times can be altered to gain optimum production.

I normally turn off specific wavelengths with most full spectrum lights to modify the light to my plant’s stage and needs. In many ways, LED lights are healthier than even sunlight for your indoor plants.

Are plants grown under full spectrum lights healthier?

Yes, plants grown under full spectrum lights are healthier because they produce more UV rays and less heat or IR rays

generated by other light sources.Other light sources often cause plants to burn and dry up.

You'll also need to use more water and energy to keep the plants growing.

However, with LED grow lights the harmful wavelengths are extremely limited so your plants will need less water and power to grow. LED lights help to create healthier plants than other types of grow lights.

Are LED lights environmentally friendly?

Yes, LED lights are very ecologically friendly. The lights are 100 percent recyclable. Also, unlike HID lights, they do not contain mercury or other toxic substances.

If you want to be sure that your LED lights are environmentally friendly, then always make sure you purchase lights that are certified by RoHS.

Can LED lights cause you to go blind?

Unfortunately, LED lights do produce a certain blueness which can cause blindness in some individuals.

If you're sensitive to the blue light of LED lights, then you should wear grow room glasses that offer UV protection when working your grow room.

Is it true that full spectrum lights cannot be used in high heat?

LED grow lights do not function well in elevated temperatures. The increased warmth causes the diodes to fail, and the quality of light starts to fail.

I suggest installing a fan system to keep the full spectrum lights cool if your indoor grow space becomes too hot.

Do LEDs lose their colors as they age?

Yes, some LED diodes do change color as they age. Aging LEDs can start to produce altered colors. Failing colors is a widespread problem with cheaper LED chips.

You shouldn’t encounter any problems if you buy quality full spectrum lights for indoor plant growth.  

Full spectrum lighting is the revolutionary future of all indoor gardening. The advantages of the lights far outweigh the negatives.

If you seek robust vegetative growth and an ample harvest, then you should invest in the best full spectrum lights for indoor plant growth.
