LED Full Spectrum Light vs LED Target Spectrum Light


With the development of LED lamp technology, people are increasingly dissatisfied with the convenience brought by the current LED lamp and have higher requirements for it. The full-spectrum light is closer to sunlight. The target spectrum light should be more efficient and energy-saving. The full spectrum light and the target spectrum light will play different roles in different directions.

A summary of the full spectrum lamp

Full spectrum refers to the sunlight spectrum or close to the sunlight spectrum. The full spectrum not only protects visible light but also includes ultraviolet and infrared. The color rendering energy of the light source to the object is called the color rendering index of light, the color rendering index of natural light (Ra) is 100, and the Ra of the full spectrum is close to 100. The sunlight spectrum and color temperature change with the seasons and the time of day and night. And the color temperature and spectrum of the full-spectrum lamp also change with the changes in the seasons. The artificial full-spectrum light source will be close to sunlight in all aspects. Only in this way can it be more in line with the law of biological growth.

5000 years ago, people’s living habits and laws were determined by sunlight, working at sunrise, and resting at sunset. With the development of technology and industry, people invented incandescent lamps, fluorescent lamps, and new LED lamps. With the advancement of materials and technology, people’s pursuit of light sources is becoming more and more diversified. And with more and more demand for sunlight, artificial light is closer and closer to sunlight. The long full-spectrum range of LED light sources has made it a key research target for full-spectrum artificial light sources. LED full-spectrum lamps have also become a hot spot in the industry.

Advantages of LED full spectrum lights

LED full-spectrum lights have many unique advantages. All of its advantages come from full spectrum and close to sunlight. These two points can derive many other advantages. Let’s briefly list them below.

  1. The color rendering of the full-spectrum light source is better, closer to 100. Based on the research of different LED specificity R9 (reproduction quality index of vivid colors) and Ra value, the full-spectrum LED spectrum is more continuous than the ordinary LED spectrum. The color gamut distribution is also better, and the Ra and R9 scores are also higher.
  2. The full-spectrum light source is close to the sunlight source, which is more suitable for plants to supplement light. The growth of plants not only requires blue light with a wavelength of about 460 and red light with a wavelength of about 660 but also requires ultraviolet light. Especially for berry plants, ultraviolet light can effectively promote the synthesis of sugar. Plants have evolved for hundreds of millions of years. As a result, their various physiological states are more adapted to sunlight. Different spectrums of sunlight have different effects on plants, and full-spectrum LED growth lights can even promote plant growth.
  3. Full spectrum light source is very important for animal growth. Under full-spectrum light, the spirit of the animal will be better, the coat color will be brighter, and the vitality will increase. The full-spectrum light source can also promote blood circulation, improve immunity, and promote the absorption of calcium by the animal.
  4. The full spectrum is beneficial to human health, and different spectrums have different effects. Short-wave ultraviolet rays help the body’s vitamin synthesis, calcium absorption, promote growth, and strong bones. 592nm spectrum: match with the peak light absorption of blood vessels to improve blood circulation. 650nm spectrum: match the light absorption peak of cell mitochondria, enhance cell function, promote metabolism, etc.

Main uses of LED full spectrum lights

  1. LED full-spectrum lights can be used as street lights, indoor and outdoor household lights, and other light sources. The Ra and R9 of the full-spectrum lamp are better, with good color rendering and spectral continuity. It is the preferred light source in life. The color of the objects under full-spectrum light that is close to sunlight is more natural. Moreover, some of the light emitted by the full-spectrum lamp is beneficial to the human body. With high efficiency and low energy consumption, LED full-spectrum lamps are great for household light sources and street lamps.

  1. LED full-spectrum light can be used for indoor planting. The full-spectrum lamp has a full range of wavelengths, almost containing all kinds of shades needed for plant growth. Under the illumination of full-spectrum lamps, plants can thrive indoors.

  1. LED full-spectrum lights can be used as lighting sources for indoor animal breeding. The light emitted by the full-spectrum lamp can simulate the living environment of animals under the sun. In this way, animals will not grow deformed due to lack of light. At the same time, the ultraviolet light emitted by the full-spectrum lamp has the function of sterilization, making the growth of animals less affected by bacteria.

Overview of LED target spectrum light

The target spectrum lamp refers to a lamp whose emitted spectrum is close to the previously required spectrum. The spectrum of the lamp is generally simple, consisting of a single or a limited number of spectra. With the development of social science and technology, people have new requirements for efficiency and energy consumption. The spectrum of the target spectrum lamp is closer to the required spectrum. This will greatly improve the utilization of light and reduce energy consumption.

Advantages of LED target spectrum

  1. The LED target spectrum light will be more efficient. Since the target spectrum lamp is designed to complete the target, the light emitted is for higher efficiency.
  2. The LED target spectrum light will be more energy-saving. The utilization rate of light emitted by the target spectrum lamp is higher. It can achieve the maximum effect with the minimum light intensity, and realize the goal with the minimum energy consumption.

Main uses of LED target spectrum light

1. Indoor plant light

Using LED target spectrum lights as plant growth lights, the spectrum produced is more conducive to the photosynthesis of plants. The target spectrum light has high efficiency despite low light intensity. And it generates less heat, which is more energy-saving and environmentally friendly. At the same time, the plants can grow better due to the generation of less heat. Reasonable use of different target spectrum lights will speed up the growth of plants and accelerate the growth cycle of plants. And the growth of plants will not be affected by the season, morning and evening, and can harvest in a shorter time.

2. Landscape plant lights

The LED target spectrum light has a relatively simple spectrum and beautiful colors. It can serve as a night light for ornamental plants to illuminate the dark environment and enhance appreciation.


LED full-spectrum lamps have been studied for many years. Although the spectrum is complete, they are still far away from sunlight, especially infrared and ultraviolet light. The spectrum of infrared light and ultraviolet light beads is difficult to form a continuous spectrum with other spectrums, and the cost is very high. Although the full-spectrum LED light has a complete spectrum, not all the spectrum is effective. So there will inevitably be some waste of resources.

LED target spectrum lights also have different problems. Although scientists have found luminescent materials that can produce specific light, some colored lights are still difficult to produce. And the production efficiency is not high, and the cost is relatively high. In fact, the demand for light for plant and animal growth is complex. It’s not just one or two kinds of light that can solve the problem well. Only a few plants can grow healthily under the target spectrum such as red and green light. The light needed for animal growth is more complicated.

Nowadays, most LED lights are still full-spectrum LED lights, but with the breakthrough of related research on plant growth, more and more target spectrum lights will appear in the varieties of plant growth lights. This is due to the fact that people are constantly pursuing higher efficiency and less energy consumption. For the purpose of plant cultivation, the use of spectrum lights will increase. MOKOLight’s research on LED has been at the forefront of science and technology and has its own unique views on the production and manufacturing of LED. The MOKOLight full spectrum light and target spectrum light are advanced and the technology is developed.
