The primary function of lamps is to provide illumination. Whether it's a common household lighting fixture or a decorative lamp, their purpose is to emit light. Even fill lights serve the purpose of providing illumination. While LED lights used in homes are primarily used for lighting or decoration, plant lights have an additional and crucial role as supplementary light sources. So, what sets these two types of lights apart?
Growers purchase plant lights to provide plants with sufficient light when natural sunlight is limited due to cloudy or rainy weather. The development of plant lights is centered around replicating the sunlight absorption process during photosynthesis. The spectrum, power, and intensity of plant lights are designed to meet the specific growth requirements of plants.
Extensive research has revealed that most plants absorb and utilize red and blue light from sunlight most effectively. As a result, many plant lights incorporate the red and blue light spectrum, focusing on specific wavelengths that have a significant impact on plant growth, such as 450-470nm for blue light and approximately 660nm for red light. These wavelengths have been proven to be highly beneficial for promoting various aspects of plant growth, including the development of stems and leaves, flowering, and fruiting. While some household LED lights may also emit red and blue light, their wavelength range typically falls outside this effective range, rendering them ineffective for plant lighting purposes.
Therefore, the key difference between plant lights used for supplemental lighting and LED lights intended for household use lies in their respective spectrums and the specific wavelengths of light they emit. This disparity in light quality and wavelength results in distinct effects on plants. Household LED lights lack any supplementary light effect on plants and are not suitable for supporting plant growth.
