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 plants photosynthesis; no energy waste like fluorescent lights etc. 630 and 460nm are respectively 2 peaks of growth spectrum for maximum chlorophyII A and B production. Sources rich in red light are more efficient and beneficial for photosynthesis, best for blooming and fruit .The Chlorophyll and Carotenoid need blue much, good for the photosynthesis, best for promoting the leaf.This lamp is waterproof ,IP65.
