Würth Elektronik offers horticulture LEDs with different wavelengths. The most important wavelengths are 450 nm, 660 nm, and 730 nm. However, to optimize the spectrum, additional wavelengths are needed for different quality parameters of the plant. This slide indicates all suitable wavelengths for horticulture. All the high-power LEDs feature the same size and are mostly used in greenhouse lighting systems where the distance between luminaire and plants is high.
