>-Utilizes Violet, Blue, and Green bands to promote Vegetative Growth>-Utilizes Red band to promote flowering and budding>Specifications:>Watts Used: 40>Incandescent Equiv.: N/A>Size: 47.25" x 6" x 2.75">Color Temp: Grow Light>Warranty: 5 Year Limited>The chart indicated the 2 primary color bands this fixture utilizes>-Studies have shown that through photosynthesis, plants utilize primarily 429nm, 469nm, 642nm and 667nm.>-Range 400-520nm includes violet, blue and green bands. Peak absorption by chlorophyll occurs and a strong influence on photosynthesis (promotes vegetative growth).>-Range 610-720nm is the red band where large amounts of absorption by chlorophyll occurs, and the most significant influence on photosynthesis (promotes flowering and budding). The ratio of red (660nm) to far red (730nm) in sunlight is about 1.2:1.>Are you going to place all 4 of them in parallel?Yup. I have 8 other 4' LED lights on two other shelves for seedlings. I may buy up to 6 of these and intermingle them with the rest until I need to overwinter adult plants next winter. It is the setup you see in
