This led grow bulb has low power consumption, high luminous efficiency, and long
service life. These growing lamps emit the wavelength of light which can be fully absorbed
by the plant's photosynthesis; no energy waste like fluorescent lights etc. 630 and 460nm are
respectively 2 peaks of growth spectrum for maximum chlorophyll A and B production.
Sources rich in red light are more efficient and beneficial for photosynthesis, best for
blooming and fruit. Chlorophyll and Carotenoid need blue much, good for photosynthesis, best for promoting the leaf.
