660nm vs. 680nm LEDs: What Are the Differences and Applications?
Both 660nm and 680nm LEDs belong to the deep-red spectrum and are widely used in horticultural lighting and plant research. However, they have slightly different spectral characteristics and application focuses.
660nm LEDs for Plant Growth
660nm is one of the most commonly used wavelengths in LED grow lights. It is strongly absorbed by chlorophyll and plays an important role in photosynthesis. It is widely used in indoor farming, greenhouse lighting, vertical farming and supplemental plant lighting.
680nm LEDs for Specialized Plant Lighting
680nm light is close to the red absorption region associated with Photosystem II (PSII), an important part of the photosynthetic process. It is useful for studying plant photosynthesis and optimizing the spectral distribution of horticultural lighting systems.
Which Wavelength Should You Choose?
660nm is a popular choice for general plant growth applications, while 680nm can be considered for specialized lighting designs and spectral optimization.
Both wavelengths can contribute to photosynthesis. The best choice depends on plant species, light intensity, growing conditions and the overall LED spectrum.
For professional horticultural lighting, combining different red wavelengths with blue and white LEDs can help create a more balanced lighting solution.
