LED plant grow lights use light-emitting diodes (LEDs) as a light source, extracted to simulate the sunlight spectrum required for plant growth, using light instead of sunlight to create plant growth and development, which helps to shorten the growth cycle of the plant. The light source consists mainly of red and blue light sources. The light bands to which plants are most sensitive are used. The wavelength of red light is 630nm and 640-660nm, and the wavelength of blue light is 450-460nm and 460-470nm.According to the research, the light source of this band can make the best photosynthesis of the plant, so that the plant can get the best growth condition.
The user groups of LED plant lights are mainly individual users, research institutes, greenhouses, and three-dimensional forms. Users who like plants use fill light to fill light for plants at home; research institutes mainly use it for experiments, and greenhouses and three-dimensional farms mainly use it to shorten the growth cycle of crops, control flowering, and cultivate economic crops. With the legalisation of marijuana in some parts of Europe and the United States, more and more users are starting to use LED plant lights to grow marijuana. With the help of LED plant grow lights, marijuana yields and quality have improved dramatically.Thump's LED plant lights, mobile grow racks, and vertical air solutions enable indoor cultivators to maximise growing area and increase yields through advanced vertical farming techniques.
LED lights last for thousands of hours and have better energy efficiency. This makes them an excellent choice for home and commercial use. Each common LED light has its own unique spectrum, and different LED lights have different spectra.It's just your luck that LED lights will cover a portion of your plant's growing needs.Because the colour temperature, spectrum, and illuminance are all uncertain, LED lights are not suitable for plant fill light.
The first one is brightness, according to the plant species, for example, shade-tolerant plants and light-loving plants need different intensities; the second one is spectrum, the plants absorb different wavelengths of light differently, and different wavelengths of light affect the plants differently. In short, blue light near 450 nm has an effect on the synthesis of proteins and organic acids, germination, and photosynthesis. red light near 660 nm has an effect on the formation of carbohydrates, e.g., the flowering of flowering plants.
Plants have a different sensitivity to the spectrum than the human eye. The most sensitive spectrum for the human eye is 555 nm, between yellow and green. It is less sensitive to blue and red light. On the other hand, plants are most sensitive to red light and less sensitive to green light, but the difference in sensitivity is not as great as the human eye. The most sensitive region of the spectrum for plants is 400-700 nm. This region of the spectrum is often referred to as the active energy region for photosynthesis. About 45% of the sun's energy is located in this part of the spectrum.

If an artificial light source is used to supplement the amount of light, the spectral distribution of the light source should be close to this range. The energy of photons emitted by a light source varies with wavelength. For example, 400 nm (blue light) has 1.75 times the energy of 700 nm (red light). But for photosynthesis, both wavelengths are equally useful. The excess energy in the blue spectrum that cannot be used for photosynthesis is converted into heat. The rate of photosynthesis in a plant is determined by the number of photons the plant can absorb at 400-700nm, independent of the number of photons emitted in each spectrum.
Light energy is absorbed by chlorophyll and carotene in leaves. Two photosynthetic systems convert glucose and oxygen into energy to fix water and carbon dioxide. This process uses all of the visible light spectrum, so different coloured light sources have almost the same effect on photosynthesis. Some researchers believe that the red part of the orange colour has the greatest photosynthetic capacity. However, this does not mean that plants should be cultivated under this monochromatic light source. For the development of plant form and leaf colour, plants should receive a balanced variety of light sources. Blue light sources (400-500nm) are important for plant differentiation and stomatal regulation. If there is not enough blue light and an excessive proportion of far-red light, stems will overgrow and tend to cause yellowing of the leaves. The ratio of red spectrum (655-665nm) energy to far-red spectrum (725-735nm) energy is between 1.0 and 1.2, which is positive for plant development. But each plant has a different sensitivity to these spectral ratios.
Plant growth, from photosynthesis to nutrient production, requires exposure to different wavelengths of the spectrum at each stage, i.e., the full spectrum of sunlight, and the spectrum of an LED plant light meets the needs of plant growth because it is customised specifically for plants.
LED lamps do not have such a rich spectrum, because it is not designed for plants to supplement the light, LED lamps are more used with people's life lighting, with the progress of LED technology, a variety of LED lamps gradually replace the traditional lamps appear in people's lives, compared with traditional lamps, LED lamps light source emits better, less in energy consumption, the lamp itself does not have any harmful substances and Pollution materials, the use of safe and environmentally friendly, low heat generated when working, the use of the term is the traditional lamps and lanterns of multiple times and other advantages.
Now all products are progressing and innovating, each product has its own functional advantages, just like LED lights and LED plant lights. The difference between them is that they are used in different scene environments, one is only used in plant cultivation, one is used in people's lives, and they have different functions, if you are a grower, you can choose LED plant lights, if you are a home or commercial lighting you can choose LED lights, it will bring different surprises.
