1、 LED light

LED lamp is the most commonly used plant fill light lamp at present. It has many advantages, relatively power-saving, low cost, long service life and small space. The light wave emitted contains the red and blue light required by plant photosynthesis, which can meet the needs of plants for light. It has a wide range of applications. It can also be used in greenhouses and plant factories in addition to families. LED lamp also has disadvantages. Its full spectrum lamp beads are not evenly distributed. If you irradiate plants in a small area at close range, the spectral distribution is not balanced for small plants

2、 Little sun

The small sun has strong illumination ability, which can fully imitate the sunlight and supplement sufficient sunlight to plants. However, for some plants, the illumination is too strong and very electricity consuming

3、 Rare earth lamp

The main component of rare earth lamp is copper selenium powder, which can cause specific spectrum and provide light energy for plants. Rare earth lamps have uniform luminescence and strong spectral continuity, but they also have disadvantages, such as high energy consumption and short service life

4、 Trichromatic

The advantages of three primary color lamps are relatively cheap, inexpensive, obvious disadvantages, large energy consumption, unreasonable spectral distribution and unsuitable for long-term use
