White LED bulbs are highly efficient and have a leading position in low-power markets such as flashlights, solar garden lights and pedestrian lights, bicycle lights, and more. Monochrome LED lights are commonly used to create traffic lights and holiday lights.
In 2010, LED lights became a hot topic in horticulture and agriculture. NASA pioneered the use of LED lights in space, followed by home and commercial indoor gardening. These planted special lamps are specially designed, and their light waves are just the wavelength of chlorophyll absorption, which promotes the growth and reduces the light waves that the plants do not absorb, resulting in waste. In the visible spectrum, photosynthesis only needs red and blue, so these lamps are designed in both colors. Compared with similar products, these LED lamps can provide the same brightness, no ballast, and much less heat than gas discharge lamps. It is suitable for indoor planting. Less heat can reduce evapotranspiration, thus reducing the number of irrigation. For this reason, when using these planting lights, plants should not be over-supplied.
