WINGER® WEPRB3-S1 Power LED Star royal blue (450nm) 3W - 35lm

Product description

These deep royal blue LEDs on a Star-PCB are particularly favorable for plant breeding by their wavelength of about 450nm. Studies show that plant growth is most effective at deep red light (650nm~660nm) and royal blue light (440nm~450nm). Photosynthesis is most effectively activated or increased at about 650nm ~ 660nm. The combination with deep red light stimulates the flower and leaf growth. This royal-blue LED with its correct range of wavelength is therefore much better suitable for the plant lighting as standard blue LEDs with 470nm. The royal-blue light of 450nm is near the chlorophyll(b) peak sensitive point of the plants and is important for leaf growth. It is essential for healthy plant growth. We do recommend a combination with 650nm LEDs and a 700mA constant current driver as power source. Ensure sufficient heatsink for the LED.
