Using LED technology to promote plant photosynthesis, the control performance of light quality, light quantity, and light period is far better than other artificial light sources. LED is not only efficient in electrical energy utilization but also unmatched by other light sources in controlling the absorption spectrum of plant photosynthesis In visible light, substances produced under red light make plants grow taller, while substances produced under blue light promote the accumulation of proteins and non-carbohydrates and increase plant weight Blue light is a necessary complementary light quality to red light for crop cultivation and is necessary for normal crop growth. Blue light inhibits stem elongation, promotes chlorophyll synthesis, promotes nitrogen assimilation and protein synthesis, and promotes the synthesis of oxidizing substances Blue light has many important roles in plant photomorphogenesis, including pore control, stomatal control affecting water relations and CO2 exchange, and stem extension and light orientation Red and blue complement each other. Depending on the ratio of red and blue light, leaves have higher photosynthetic rates, which may be associated with higher nitrogen uptake. The typical blue light response in higher plants is phototropism, which inhibits young stem elongation, stimulates stomatal opening, and regulates gene expression. Normal plant development and yield formation can be achieved with red light as the main light and blue light as a supplement Easy to use and install: no need to worry about dehydration in the sun No need to move in and out, giving plants a comfortable living space Thickened aluminum lamp base: sturdy and durable, fast heat dissipation design, long service life LED spectrum light source: sturdy and durable, fast heat dissipation design, long service life Light effect regulator: the light effect of the lamp can be freely adjusted, and the brightness is easy to use Clip design: clip design, is easy to install and wide range of application Universal hose: light direction can be freely adjusted according to different irradiation angles Specifications: Product name: 5 light head plant growth light LED quantity: 100pcs(65pcs red and 35pcs blue) Material: Aluminum, PVC Plug: USB Input voltage: 5V Input current: 3A Wavelength: (Red: 645-655nm/Blue: 455-465nm) Operating temperature: -20℃-40℃ Life span: 50000 hours Range: 2-3㎡ Lamp to plant suitable distance: 0.98-3.98 feet (30-120cm) Note: 1.
