In the visible light spectrum, the wavelength of red light ranges from about 620nm to 750nm. Compared to 660nm bright deep red light, 730nm far red light is closer to the boundary of infrared light. In 730nm strip with SMD 2835, 3528, 5050 as the 730nm LED light source, the 730 nm light shows a red color and is directly visible. Due to the human eye's low sensitivity to long wavelengths, the visible red illumination range of 730 nm red light is smaller compared to the common 620-630 nm red light, which is concentrated near the strip.
Red light at 730 nm wavelength can be absorbed by plants and plays an important role in plant growth. Far red 730nm led grow light penetrates deep into the plant canopy and effectively promotes the plant's shade avoidance response, allowing the plant to elongate its stems while regulating the flowering cycle. Supplementing plants with 730nm far-red light rays also enhance photosynthesis and increase plant biomass, which in turn enhances plant resilience and helps plants to grow better under various environmental conditions, especially beneficial for ornamental flowers.
We offer a wide range of protection levels and light densities of hyper red 730 nm led strips to suit different environments and needs of plant growth rooms. View our products today.
