1. What is a full spectrum LED

The full spectrum refers to the spectrum curve that includes ultraviolet, visible, and infrared light in the spectrum, and the ratio of red, green, and blue in the visible part is similar to that of sunlight, and the color rendering index Ra is close to 100.

the wavelength of full spectrum LED

The spectrum of sunlight can be called the full spectrum. The color temperature changes with the four seasons and the time of morning and evening.

Therefore, the spectrum of the full-spectrum lamp should change the color temperature successively with the change of time, and simulate the natural light environment to be more in line with the natural growth laws of organisms.

The continuous spectrum of solar radiation at noon on a sunny day, with a color temperature of 5000K, is divided into two parts: visible light and invisible light.

The wavelength of visible light is 400-760 nm, and it is divided into 7 colors: red, orange, yellow, green, cyan, blue, and purple, and it is concentrated as white light;

There are two types of invisible light, infrared with a wavelength greater than 760nm and ultraviolet light with a wavelength of 290-400nm.

the wavelength of sunlight spectrum

The blue light spectrum in ordinary LEDs is relatively high, lacking violet light, cyan light, short-wave green light, and long-wave red light. At present, full-spectrum LEDs are realized by chips and phosphors. Phosphors with wavelengths in the recessed region are used to complement the spectrum.

The color rendering ability of a light source to an object is called color rendering. The color rendering index of sunlight is defined as 100. The closer the color rendering index (Ra) value is to 100, the better the color rendering.

15 sample colors are used to evaluate the color rendering of the light source. The special color rendering R9 is an indicator of the reproduction quality of the vivid red color of the LED. The higher values of Ra and R9 are the performance of high-quality LEDs.

different RA values

Compared with ordinary LEDs, full-spectrum LEDs have a more continuous spectrum and wider color gamut; the color rendering index Ra is greatly improved, closer to 100; the special color rendering index R9 can be as high as 90 or more.

2. What is a full spectrum grow light LED

The full-spectrum LED grow light is a lighting source developed by simulating the solar spectrum, which is conducive to plant growth. 

Visible light in the spectrum ranges from 380NM blue light to 780NM red light. The proportion is reasonable, and the light wave curve imitates the shape of the solar spectrum. 

The light color is like the sunlight color at 10 am, with strong color rendering, small color temperature drift, high luminous efficiency and large luminous flux.

purple LED and blue LED

Full-spectrum grow lights refer to white light grow lights, and white light contains all spectrums.

White LED grow lights offer a full spectrum and can mimic natural light, giving plants a balanced spectrum of red, blue, and green.

While the spectrum used varies, white LED grow lights are designed to emit a similar amount of red and blue light, with the added green light appearing as white.


Depending on the type of plant being cultivated, the stage of cultivation (such as germination/vegetative or flowering/fruiting), and the photoperiod required by the plant, a specific range of the spectrum, luminous efficiency, and color temperature are desirable for specific plants and time periods.


Incandescent lamps, although the spectrum is unevenly distributed, the spectrum is relatively comprehensive.

Under the condition of illuminance, it still has a certain effect on the growth of plants, but the light efficiency is too low, the energy consumption is large, and the service life is short.

different light bulbs

Sodium lamps, energy-saving lamps, have large curve changes and uneven spectral distribution.

The red and blue ratio of LED plant lights has certain advantages, but the spectrum cannot be compared with sunlight, and the cost is high. The light color is purple and the brightness is low.

3. Features of Full Spectrum Grow Lights:

The full-spectrum plant light bulb is developed according to the wavelength range of sunlight required for plant growth and the required illuminance.

The rational use of this light can not only reproduce and grow under conditions that are not suitable for plant growth but also accelerate crops. It can improve breeding and shorten the growth cycle of crops, and avoid the occurrence of diseases, insect pests, and deformed fruits.

  1. Full-spectrum grow light is an artificial light source with full-spectrum, and the resulting light beam is most suitable for plant growth (chlorophyll, anthocyanin, carotene)
  2. With the floodlight effect of special floodlights, the illuminating light effect is evenly distributed, and the light efficiency is twice that of other sodium lamps of the same wattage and seven times that of incandescent lamps.

4.The effect of spectral range on plants

The light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation.

The wavelength of 400-420nm helps to form anthocyanins and resist the elongation of branches and leaves.

The wavelength of 450-460nm can thicken stems and leaves, accelerate plant development, and regulate stomatal opening.

The wavelength of 550nm promotes the growth of oxygen and helps tissues better store nutrients.

The wavelength of 580nm can promote the growth of roots and early germination.

The wavelength of 650-660nm promotes the overall growth of plants, especially in the flowering and fruiting periods, increasing the growth rate (20 days earlier for flowering and 30 days for earlier harvest), and also increases the number of fruits by 25% to 35%, and reduces deformed fruits. incidence rate.

The absorption rate at 720~1000nm is low, which stimulates cell extension and affects flowering and seed germination.

5.Which one is better for grow light? Full spectrum or red and blue light

Plant lights can replace sunlight to supplement light for plants to promote plant growth. They can be used when planting vegetables, fruits, and flowers. They can not only promote the growth of seedlings, but also promote flowering and fruiting, increase production, and advance the market.

There are many types of plant lights, and the spectrum includes full spectrum and red and blue light spectrum.

Is the grow light better with a full spectrum or red and blue light spectrum?

After research on the absorption and utilization of sunlight by plant growth, it is found that the absorption and utilization of red and blue light in sunlight by plants is the largest.

Red light can promote the flowering and fruiting of plants, and blue light can promote the growth of stems and leaves of plants, so in the later research on plant lights, people developed plant lights with a red and blue spectrum.

This kind of light has the best effect on the growth of plants and has a better effect on crops and flowers that need to ensure color. Moreover, the red and blue light can be matched according to the needs to obtain the most suitable spectrum for plant growth.

There are only two spectrums of red light and blue light in the red and blue grow light, while the full-spectrum grow light simulates sunlight. The spectrum is the same as that of sunlight, and the light emitted is white light.

Both of them have the effect of supplementing light to promote plant growth, but different crops should pay attention to choosing the most suitable one when choosing the spectrum.

For flowering and fruiting, crops and flowers that need to be colored, it is best to use red and blue grow lights, which can color, promote flowering, and increase yield.

For leafy crops, full-spectrum grow lights can be used.

If you grow plants at home, it is best to choose a full-spectrum light bulbs for home, because the red and blue light of the grow light is pink, and people will feel dizzy, nauseated, and uncomfortable if they are in this environment for a long time.

6. The Benefits of Full Spectrum COB LED Grow Lights

Full Spectrum COB LED Grow Lights are engineered to provide the full spectrum of visible light that plants need for biological processes. Your plants need different wavelengths of light throughout their growth cycle because each color spectrum targets a different growth and developmental function for a plant.

Blue light promotes root development and stout growth.

Red light promotes germination and high yield during flowering.


Even a green light can make a difference. While plants absorb only trace amounts of green light for photosynthesis, chlorophyll reflects green light, allowing it to penetrate deeper into the canopy as light bounces from the top of one leaf to the underside of another.


LED COB full-spectrum grow lights are tailored to meet your exact plant needs. No overuse of chromatograms and no exclusion of necessary wavelengths.

The main limitation of COB LEDs is that they are fixed spectrum. It is not possible to change the spectral combination as with traditional SMD LEDs. The spectrum of COB LEDs is formulated by mixing a custom phosphor blend used as a coating on COB LEDs.

The spectrum can be slightly altered by changing the phosphor mix. Traditional SMD LEDs can be mixed to achieve specific light spectra and altered by raising or dimming different colors.

7. Full spectrum lights for birds

We all know that the grow light is used to help vegetables and fruits in the greenhouse. The grow light is made according to the sun, which can effectively help plants grow and bear fruit.

Birdhouses require partial shading and cannot expose birds to direct sunlight for long periods of time. But that doesn’t mean birds don’t need sunlight, just like the vast majority of organisms, parrots need sunlight to survive and thrive.

The synthesis of vitamins in animals, the growth of the body, the reproduction of hormones in the body, and the chemical reactions of the brain are all affected by light.

It is worth mentioning that there is a big gap between indoor artificial lighting and natural light (sunlight), and the former cannot meet the needs of the body’s growth.

The light from ordinary incandescent lamps has almost no UV light and lacks green light. The spectrum of light emitted by fluorescent lights is more comprehensive but still different from sunlight.

Just as a long-term lack of certain foods can cause vitamin deficiencies, a long-term lack of natural light exposure will negatively affect every bodily function of parrots, resulting in physical and psychological diseases.

When raising parrots indoors, it is often necessary to place the parrot near the window so that it can receive direct sunlight.

Note that window glass blocks 99% of UV rays, so remember to keep the windows open when letting your parrot get some sunlight.B

When you can’t get your parrot to sunbathe regularly, you can choose a professional full-spectrum light bulb.

The artificial full-spectrum light source has the same seven colors as sunlight, which are the familiar red, orange, yellow, green, blue, indigo and violet, while the general artificial light has only three colors orange, green, and indigo.

As a supplemental light, the light can be enhanced at any time of the day. An effective lighting time can be extended in the winter months.

Tropical fish farming, aquatic weed farming, and reptile farming often require the use of this full-spectrum light source.

7.1 What are the benefits of full spectrum lights for birds?

Most birds are colorblind when there is no light. This is why most birds are diurnal because they have excellent vision when there is sunlight.

If you are keeping a bird in captivity, it is advisable to ensure that their new environment mimics their environment in the wild in some way, including exposure to light, you can place their cage in a place where there is still sunlight, or if that is not possible, you may want to invest in full-spectrum lighting so they can see vibrant colors allowing them to do different things that keep them busy, like playing, eating, and flying.

Here are other benefits of full spectrum light.

  1.  In terms of physiology, full-spectrum light is a source of vitamin D3, and proper absorption of vitamin D3 can be an important factor in having strong and healthy bones.

With insufficient full-spectrum light, your bird may be stressed, and fatigued, and its immune system suffers.

  2. When your birds get enough light, they can absorb nutrients like vitamin D, vitamin A, vitamin E, and calcium.

If your bird is unable to absorb these different kinds of nutrients, it will gradually get sick.

  3. Allowing birds to bask in the sun can help them avoid behavioral problems such as excessive squeaking, plucking their own feathers, and biting. Your bird will also become energetic.

The lack of full-spectrum light can also affect their overall physical development.

  4. Even if your bird is placed near a window, it may still not provide enough light needs. So using full spectrum light is a great addition for birds.

   5. Birds have good eyesight as long as they are in a well-lit environment.

If you keep your bird indoors, using full-spectrum light, your bird can process visual information just as well as its visual function in the wild.

If your bird can see clearly, then you can be sure that it will live happily.

  6. Using full spectrum light is also a great equipment to ensure that your bird’s life will last no matter the seasons change.

7.2 How to Use Full Spectrum Lights for Birds

  1. It is important to have a lighting schedule that is more like a photoperiod. There will be no change in birds’ hormonal function when using daylight mode, which will be a crucial factor to consider if you are breeding.
  2. Make sure only to use full spectrum light that is suitable for birds. Grow light is not a good choice for birds.
  3. You need to hang the lamp above the birdcage, so the full spectrum light will shine into the birdcage without adding heat.

           But you need to make sure all parts of the cage are under the light.

  1. If the full spectrum light is on, make sure to observe the temperature around the cage. If the temperature in the cage is gradually increasing, you will need to move the LED grow light bulbsslightly away from it.


No matter which style of full-spectrum bulb you choose, you’ll want to place the light source very close to the bird—about 60-90 centimeters from the cage. So that parrot can get the most help in this artificial full spectrum light source.

When you purchase a light, make sure that it is a full-spectrum bulb, some bulbs may not contain the full spectrum.

Supplementing parrots with full-spectrum lighting time can stimulate mating and reproduction in some parrots, in addition to ensuring the parrots are healthy.

birds under full spectrum light

During wintertime, there are only 10 hours of light a day. During this time, African parrots that breed in the winter begin to mate and enter the nest to lay their eggs, while the remaining species rest.

When spring comes, you can gradually extend the daily light time to 14-15 hours. Increased daylight hours can boost the reproduction of Amazon parrots and some other species.

When you keep your parrot indoors, no matter the season, provide no less than 10 hours of full-spectrum lighting per day, but no more than 16 hours, otherwise the parrot’s health will be endangered.

7.3 How to choose the correct index light fixture for birds

Full-spectrum fluorescent bulbs are measured by their color temperature, color rendering index(CRI), and brightness. Color temperature, or chromaticity, is the whiteness of light emitted, measured in degrees Kelvin.

If the value tends to be higher, the color is more white, but if the value of color temperature is lower, it tends to be yellowish.

The ideal color temperature for a full-spectrum bulb is around 5250 K, so choose one that is the same or has the closest color temperature. For the color rendering index, if it is for birds, the most suitable value is around 100, but 98 and above are good.

For brightness measured in lumens, 5.0 is fine for birds.

8. Full spectrum for human

Only ionizing radiation will cause harm to the human body, and the visible light emitted by the full-spectrum LED grow light belongs to non-ionizing radiation, which will not cause harm to the human body.

Led plant growth lights are the same as general indoor lighting, except that they are specifically aimed at people and do not illuminate plants.

If the light shines on people 24 hours a day, people can’t sleep. Or the brightness is too strong, always facing people’s eyes. That would be uncomfortable. There is no harm in normal use.


The full-spectrum plant light is a lighting source developed by simulating the solar spectrum that is conducive to plant growth. The visible light in the spectrum ranges from 380NM blue light to 780NM red light in a reasonable proportion, and the light wave curve imitates the shape of the solar spectrum. The best daylight color, strong color rendering, small color temperature drift, high luminous efficiency, and large luminous flux.

8.1 The role of the full spectrum:

1. Effects on human health

Modern people stay indoors for a long time and cannot get the health benefits from the sun.

The meaning of the full spectrum is to reproduce sunlight and bring back to us the benefits of natural light acting on human physiology, psychology, and the human body.

different light wavelength

2. The effect on color

When the object is illuminated by a light source with a discontinuous and incomplete spectrum, the color will be distorted to varying degrees.

The rich spectrum of full-spectrum light can reproduce the true color of objects, provide vivid lighting, relieve the visual fatigue of human eyes, and improve the comfort of the user’s light environment.

3. Effects on the human body’s work and rest

According to the law of the human body clock, the human brain usually starts to secrete melatonin at 9 or 10 pm.

Blue light has an inhibitory effect on melatonin produced by the pineal gland of the human brain, and long-term exposure to high blue light may even cause sleep disorders.

The full spectrum can reduce this occurrence, but every “no blue light” lamp has this effect.


Summary: The benefits of the full spectrum are high color rendering and no blue light effects.

When purchasing lamps, instead of paying attention to whether they are “full spectrum”, it is better to pay more attention to the actual light effect. The lamps that truly achieve high color rendering and no blue light effect are the lamps worthy of our purchase.

9. Application scenarios of full spectrum light bulbs

1. Indoor professional lighting

2. Plant lighting

3. Medical lighting

4. High-end furniture lighting

5. Healthy lighting

According to industry statistics, the current proportion of full-spectrum LEDs in the LED market is only about 2%. Compared with ordinary LEDs, the cost of full-spectrum LEDs is slightly higher. Due to price constraints, there is greater resistance to promotion.

Industry insiders predict: “With the continuous improvement of full-spectrum technology, some users will realize the importance of full-spectrum light quality, and its market share will grow rapidly. The transition from high color rendering LEDs to full spectrum LEDs.”

10. The difference between full spectrum LED and ordinary LED

The principle of luminescence is fundamentally different.

Full-spectrum LED: purple chip + blue-green-red phosphor, more short-wave blue light, high energy

Ordinary LED: blue chip + yellow-red phosphor, relatively little short-wave blue light, and sharp peaks in the blue-to-green band


Blue light refers to light with a wavelength of 400-500 nm, and short-wave blue light is light with relatively high energy with a wavelength between 400 nm and 450 nm.

Blue light in this wavelength will increase the number of toxins in the macular area of the eye, which can induce blindness and seriously threaten the health of our eyes.

The colorful colors of this world can be seen by people, thanks to sunlight. Sunlight is a kind of polychromatic light. It reflects monochromatic light on objects of different colors, showing what we see. color.

The “full spectrum” in lighting fixtures refers to the light emitted by the fixture, whose spectrum is close to the solar spectrum, especially in the visible light part, the proportion of various wavelength components is similar to that of sunlight, and the color rendering index of the light is close to that of sunlight. color rendering index.

11. How to Choose the Best Full Spectrum Light Bulbs

1. Color rendering index

CRI measures the color rendering ability of light and compares it with natural light. You need a light source with a high CRI as this will be the best fit and more realistic to give you more realistic colors.

The full spectrum index analyzes the troughs and peaks provided by the SPD.

It will give you the light’s score average. When buying a full spectrum lamp, you need a lamp with a more uniform wavelength and color distribution, so try to choose a lamp with a lower score.

Your ideal bulb would have a score of 2.0 or lower, as this represents the full spectrum of true blue.

2. Determine Approximate Lumens

Lumens are a measure of the light emitted by a light source. This measurement is often used in conjunction with wattage to determine the luminous efficiency of the lamp.

The more lumens provided by the lamp, the brighter the light source. Full spectrum lamps range from 2000 to 10000 lumens. You will need to find a full spectrum light that provides maximum lumens and is energy efficient. Use energy-efficient full-spectrum lights to brighten your home or office without using excess energy.

3. Check energy efficiency

There are two main types of commercial energy-saving light bulbs. LEDs and CFLs will provide higher energy efficiency than traditional incandescent bulbs.

You can determine the efficiency of a light bulb by comparing the amount of light it produces with the energy it consumes.

4. Different types of full spectrum lights

There are a wide variety of lamps that provide full spectrum lighting. Use a desk lamp with natural light on your desk, which will reduce glare while you work and provide true color. There are also floor lamps with full spectrum bulbs that also bring natural light into your room.

Full Spectrum Light Therapy has various types of settings to provide natural light therapy to improve health. You can also purchase full-spectrum LED grow lights for indoor plants.

Next time you start shopping for lamp beads, please consult us, we can provide you with different options to meet your needs.

5. Expectations of full spectrum prices

A full-spectrum lamp can be about four to ten times more expensive than a comparable lamp without full-spectrum capability.

The higher price is it is characteristic because these lamp beads will bring you benefits that other lamp beads do not have.

LED Full spectrum lights will provide better sight lines, improve your health to increase your productivity, and provide better visibility that no other light can provide.

6. Different styles are available

Full spectrum lamps are available in many different models.

Being able to adjust where the light shines is great for those with poor eyesight. And as you age, your eyes change the way you see things. Enhance your vision and eliminate glare with full-spectrum LED light bulbs that emit light correctly, bringing you great convenience and benefits.
