Full spectrum lights include red, blue, green, yellow and other wavelengths. While growing the plants, these lights support the plants with Infrared and Ultraviolet lights. With less heat and more efficiency, the full spectrum grow lights ensure no harm to the plants.

I know you must be thinking why I mentioned it is a full spectrum light. Since they are featuring 380 to 800nm to let the plant breathe, live and grow, this product is worthy of purchasing for a healthy growth of plants.

The red light features 660nm and the blue one is 460nm. As I know, the blooming stage requires more exposure to light, the LEOTER provides red, blue and full spectrum of light to get the best result.

Besides, if you have blue, red and warm white spectrum of light, combinedly, they will work like fuel for the plant’s growth. However, these lights are not for 24 hours service and you must turn the lights off after a while.

Oh! What a pain!

But wait!

For your comfort, they have upgraded their features and set an auto timer to turn on/off the lights. Let’s check the timer option for each lights:

I think you have heard of many accidents that have occurred due to the light’s reflector. With Phlizon, you won’t get the chance of accidents because it has featured no reflector in grow lights.


A reflector is a device that lets the light reflect and spread the light on plants. The reflector accumulates heat from the lights. Sometimes, accidentes might occur for the reflector being destroyed

The reflector is not resistant to heat and it starts to melt at 80 degrees. Also, short circuits might occur that will cause problems as they are prone to melting and fire. So, Phlizon didn’t take risks for the users for the sake of beauty.

If you compare the grow lights with MH or HPS lamps, the LED lights are more efficient than those. You might have some clues but let me give you some more.

These lights are more energy efficient and keep the amount of bill less than other lights. Moreover, the light spectrum is comprehensive which allows the grow lights to replace 100 watt HPS/MH bulbs.

What else?

Well, you will see the lights have a double switch system. A double switch system plays a vital role in both veg and flowering phases. For the veg stage, you can turn on the blue and white LED lights.

In the blooming stage, the red and white lights will work efficiently because the requirement of the plant’s blooming stage is red and white light spectrums. And the seedling or young vegetative growth requirement will be satisfied by Veg switch.

What a great deal!

Oh! I forgot to mention the important feature – spectrum. These lights have featured full spectrum to promote the plant’s growth faster than before. For the beginner, this light is popular in the market because this brand solves literally every problem of gardening.

In the full spectrum feature, it has included both IR and UV lights. Do you have any idea why they are useful?

What are LED grow lights?

LED stands for light emitting diodes. By using LED chips, the LED lights help to grow the plants in full swing. Mimicking the sunlight, these grow lights help the plants from veg stage to flowering stage.

Also, the plant’s growth continues in a healthy process that supports to produce less buds and more crops. The traditional lights are less compatible than LED grow lights.

How LED grow lights works

In the LED grow lights, two types of semiconductor are added to the process. The semiconductors have positive and negative charge. Positive charge is named as holes and the negative one is called electrons.

The process needs recombination of both of the semiconductors and it only starts to work when the users provide proper voltage. Electric current lets the electron flow. During the collision, the holes generate energy which is photon.

Benefits of LED Grow Light

LED grow lights have unique features to improve productivity. The lights have accepted the newest technology and minimized the cost. They have other benefits and they are –

  • Economic

LED grow lights are more economical than HPS ones. By utilizing more than 50% energy, the lights will be supporting the users to save electricity bills.

  • Enhanced Durability

The LED will offer 50,000 to 80,000 hours which is more than enough. Compared to other types of light, the durability is far better and no tension of changing the bulbs annually.

  • Consumes Less Space

Since HPS lights generate heat which burns the plants, they need to hang at a safe distance from plants. On the other hand, LED lights are safe and you can place the lights closer compared to HPS lights.

LED Watt Requirement Per Square Foot

To be honest with my audience, wattage doesn’t determine the coverage area and efficiency of a LED. Because it depends on several factors –

  • Area size
  • Number of the plants


While setting up the area size, gardeners ask about a question – how to measure the area size for indoor gardens. Basically, it has two steps-

  • Dimension of canopy
  • Grow space size

The most common question from the gardeners is – what is the appropriate wattage for 4×8 grow tents. Stay with us to know about the calculation.

Flowering Stage

For example, you have a 4×8 ft garden where the width and height are 4ft and 8ft respectively. So, the area size is (4ft x 8ft)= 32 square foot. With a 50W per square foot LED light, you have to figure out the total wattage.

Multiply the area size with the light watt: (32 x 50)W = 1600W.

Vegetative Stage

In the vegetative stage, half of the flowering stage wattage is needed. So, the vegetative stage needs output of (1600 ÷ 2) = 800W for per square foot.

Based on the number of plants you have in the garden, the requirement changes. Have a look at the table –


After checking the chart and the rule of thumb, you will get the idea even if you are a beginner. You can start your gardening but it is always wise to discuss with the professionals. And the types of plants you want to grow in your garden is another factor to consider.

Full Spectrum Light Wavelength

Full spectrum wavelength lights must have a CRI which is more than 95 along with 6500k color temperature. If you find such lights in the market, you can purchase them to fulfil the requirement of full spectrum lights.

In grow lights, you will find different spectrum lights in the market. But not all of them feature full spectrum wavelength whereas these are the most efficient lights for plants. Their spectrum is close to the sunlight’s wavelength which is considered as the best for plants.

Full spectrum expresses the energy spectrum and it is compared to the sunlight. To be honest with the audience, without having the spectrometer, the determination of exact spectral is not possible.

What’s PAR and Why It’s Important

PAR is an acronym and the full form of PAR is Photosynthetically Active Radiation. The amount of light a plant can utilize or use is known as PAR.

As you know, the light includes the waves and photos in the visible light. By absorbing plants to use photosynthesis, plants need to have particular photons and wavelengths. 

If you think about the difference between the growing area and a canopy, PAR doesn’t refer to the absorption of all wavelengths the LED light provides. It’s the measurement of usable lights the plants take from a full spectrum light.

The importance of PAR is clear to the gardeners. Basically, the more this PAR measurement is, the more your plants will flourish. And the amount of light encourages the plants to grow naturally and in a healthy manner.

If you calibrate the lights and approach for its fine-tuning, the plants will provide you with the best results. But different stages of light require a unique type of wavelength. This process is known as OpticPAR and it includes the optimum result of customized PAR to get the best from plants.

What’s PPFD and Why It’s Important

The PPFD is the acronym for Photosynthetic Photon Flux Density and it refers to the measurement of light density in a certain area.

If you ask what is the best PPFD for plants, in general the answer will be – between 200 to 400 PPFD in the veg stage. For the flowering stage, the PPFD is 600 to 900. This range helps the plants in flowering, fruiting and budding phases.

About its importance, you know how important it is for plants to have sufficient growth lights. If you provide double PPFD, the growth rate reaches up to 85% which is fantastic. But don’t try to push the plants too much because it might hamper their physical mechanisms.

When the gardener is supplying a proper amount of PPFD, the CO2 of plants will be increasing. However, not all the lights need a huge amount of CO2 production. And so the standard range of PPFD is 600-900.

How to Hang Grow Lights

The  grow lights hanging requires many factors to consider. Your garden size, number of plants, benches, irrigation system – everything is included and it’s called uniformity.

If the lights are falling on the floor and you are paying bills for it, this will be a waste. So, plan before you buy tons of lights for a small garden.

The installation process requires a professional electrician. You have to pay them a significant amount and the amount is not rigid. It depends on the work.

Coverage Area Calculation:


Output of the fixture ÷ Light intensity = Coverage area [measured in m2]

For example, the grow light is 1500 µmol/s ÷ 800 μmol·m−2·s−1 = 1.88 m2. This is an example for my audience to understand it well. So, calculate according to the light’s features.

The hanging distance has little to no effect on the growing process. But it’s a common question asked by the beginners and here I tried to explain it.

Based on the plant’s requirements, you have to set the distance. Since no extreme heat generation is absent in LED lights, you can place the lights near to the plants.

Grow Light Vs Sunlight

Sunlight is always the best option because of the wide range spectrum. But the grow lights include proper light intensity and the photoperiod can be adjusted.

Sunlight has full spectrum wavelength which helps the life cycle of plants. However, some problems are there with sunlight.

  • The plants don’t get the full spectrum because of the window
  • Light intensity gets filtered with a number of factors
  • In the winter season, the lights will be more drafty for cold breeze though the sunlight is presence
  • Sunlight is not positioned as your wish
  • Sunlight might not be the perfect option for the shade-loving plants

On the other hand, you have the option to customize the grow lights.

  • Change the intensity and switch on the dimming option
  • No extra heat generation
  • Proper system to spread the heat using heat sink
  • Allow proper exposure to the light

LED Vs HPS Grow Lights

Among many manufacturers, the HPS lights are standardized. HPS lights feature raw energy which helps the plants to have a healthy and accelerated flowering phase. Though they have fantastic features, drawback of HPS lights is they consume massive amounts of electricity and generate extreme heat.

Also, the HPS lights require changes every 12-18 months based on the operation cost. The extra heat generation increases difficulties of plant’s growth.

If you look at the LED grow lights, you will see they are more flexible to use. These lights provide no excessive heat to hamper the growth of plants. You don’t have to change the lights once in a year because they feature long-time support.

The only problem it features is the initial costing. To be fair, these lights cost more than the other types of grow lights.

LED Vs HID Grow Lights

HID grow lights are unique in their own ways and they help the gardeners to provide expected results. These lights are economical than most of the grow lights. So, you can save money and get the best results within a budget.

High penetration of HID grow lights helps the plants to get more healthy. Also, the yielding of HID lights are better than LED lights. But they tend to produce heat which causes harm to the grow lights.

LED grow lights are expensive but the durability of these lights are 50,000 to 80,000 hours. It differs from one brand to another.

Additionally, you are not getting an excessive amount of heat like HID lights. If you are planning for a small garden, choosing the LED grow light will be one of the best decisions.

LED Vs Fluorescent Grow Lights

Fluorescent grow lights are cost efficient and they have featured many advantages. These lights are close to natural sunlight because they can support the vegetative stage of plant growth.

You will find some of your friends are super enthusiastic about starting hydroponic gardening but they lack money. For them, fluorescent grow lights will provide immense support because of cost effectiveness.

Also, the sizes, shapes, wattages and a wide range of wavelengths are the factors to consider the fluorescent lights as the best option. Previously, the gardeners complained about these lights and the authority did listen to the users.

And so, they have T5 HO fluorescent grow lights to help the growing plant in a healthy manner. The lights are perfect for the whole life cycle of a plant. No extra fixtures, sockets needed to fix the lights.

On the other hand, LED grow lights are expensive at the beginning. Eventually, their service will let you feel these lights are all the plants need. From germination to flowering, all the stages are supported by the LED full spectrum lights.

What Color Light Is Best For Plant Growth

Red, blue lights feature the best wavelength for plant growth. The best plant growth happens in the shelter of full spectrum lights.

White and green lights are less important but not unnecessary. Keeping the wavelengths in LED grow lights will increase the efficiency.

Best Kelvin for Flowering Growth

Flowering or fruiting growth requires 2700 kelvin and this is the best Kelvin for flowering. Though lights are of wide range wavelengths, not all of it is useful for the plants.

This range is perfect as it provides warmth, wavelength to the plants. And plants grow under such temperature properly.

Can Any LED Light Be Used As A Grow Light

Yes but the LED lights have to provide enough photons and warmth. LED lights that are in the market don’t provide proper lighting and so, the customized LED lights are available for plants.

Full Spectrum LED Vs Red and Blue

The full spectrum lights provide a comfortable zone to the plants to help the growth. In this process, the lights are more white and they produce a lesser amount of photons than the red and blue ones.

Because the full spectrum LED lights use the blue light and convert it into white one with a wide range of spectrum. In these lights, the phosphor converts the blue lights into white lights and let some photons come out from the LED lights.

On the other hand, the red and blue lights produce more photons for the plants. These lights are perfect for those gardens where the sunlight is available. For example, the greenhouse is perfect for having red and blue lights.

Remember one thing! Don’t try to enlighten the garden with only red or blue lights. The red light supports the photosynthesis. If you lighten up the red lights, then you will get elongated stems.

So, you need to have the combination of blue and red lights as the blue lights keep the size of plants in shape.

Purple Grow Light Vs White Light

Purple grow light is the combination of red, blue LEDs. These lights are beneficial for the plants in many aspects-

  • Promotes photosynthesis
  • Helps in flowering stage
  • Keeps the plant healthy

Red lights are helpful for photosynthesis but their effect can elongate the plants unnecessarily. To compensate for the situation, the blue lights are there. Blue lights keep the plants smaller in size and boosts the plant’s physical activities.

However, the white lights have green, blue and red wavelengths. These white lights convert blue lights into white lights with the help of phosphor. As a result, the lights provide less photons than purple lights.

Note: No white wavelengths are present practically.

LED Grow Light Distance From Plants

To be specific, the LED grow lights should be placed 18-30 inches above from the plants. This distance depends on a few factors like the type of plants, photoperiod, the coverage and wattage of lights.

Know the plants properly to get the best results. Also, try to take help from the experienced fellows you have.
