Brief introduction: Light is an essential energy source for plant growth, which regulates photosynthesis, growth and development, morphogenesis and material metabolism.Now, in the greenhouse, greenhouse planting, artificial climate chamber, make up for the lack of sunlight light source is usually used in the fluorescent lamp, high-pressure sodium lamp and incandescent lamp, the light source spectral energy distribution is designed according to the demand of the human eye to light, and needed for plant growth spectrum and human eye needs are not the same.LED (semiconductor light-emitting diode) plant growth light source, can be regulated more room, can be customized according to the different growth stages of different plants, plants to customize light intensity.It also has the advantages of low power consumption, high light intensity, long service life, cold light source (red and blue), even light quality, less heat production and so on. Main parameters: The range of light intensity: 0--2000 mol/m2 oris 400-700 nm spectrum Three LCD display, DC12V, 7AH rechargeable lithium battery Light source volume: 75 * 35 * 30mm, Luminous area: 50 * 20 * 30mm Weight: 1kg (with battery)
