2. Little Sun

3. Rare earth lamps

Four and three primary colors

LED lights are commonly used for plant lighting. These lights are very energy-saving and can provide normal light sources for plants. They are also low-cost, long-lasting, and take up little space. However, they are not suitable for irradiating small plants in a small area at close range. Small suns are also used, which can fully imitate sunlight, but are very energy-consuming. Rare earth lamps can also be used, which emit light very uniformly and have strong spectral continuity, but consume a lot of energy and have a short lifespan. You can also use three-primary color lamps, which are cheap, but consume a lot of energy and have unreasonable spectral distribution.

1. LED light

LED light is currently the most commonly used plant fill light. It has many advantages, is relatively power-saving, and has low cost. It has a long lifespan and takes up little space. The light waves it emits contain the red and blue light required for plant photosynthesis, which can meet the needs of plants for light. It has a wide range of applications. In addition to being used at home, it can also be used in greenhouses and plant factories. used in. LED lights also have shortcomings. Its full-spectrum lamp beads are not evenly distributed. If plants are irradiated in a small area at close range, the spectral distribution will not be balanced enough for small plants.

2. Little Sun

The small sun has strong illumination ability and can fully imitate sunlight and provide plants with sufficient sunlight. However, for some plants, the light is too strong and consumes a lot of electricity.

3. Rare earth lamp

The main component of rare earth lamps is copper and selenium powder, which can produce a specific spectrum and provide light energy for plants. Rare earth lamps emit light uniformly and have strong spectral continuity, but they also have disadvantages. They consume more energy and have a short lifespan.

Four and three primary colors

The advantage of the three-primary color lamp is that it is relatively cheap and not expensive. The disadvantages are also obvious. It consumes a lot of energy, has unreasonable spectral distribution, and is not suitable for long-term use.
