Product Description

New Blue COB Led 3W To 500W Les17mm High Efficiency COB LED Chip


New Blue COB Led 450nm 1919 COB LED Chip 


HuanYu Dream COB are small in size and are highly efficient LEDs with high wavelength characteristic in the range of 435-500nm (blue light). 


The COBs are highly beneficial for chicken and poultry farming, research indicates that blue or green light plays a role in alleviating stress responses in broilers due to reduction in level of serum IL-1β.

Blue light is also very useful in swimming pools, aquariums and marine lighting. It is also ideal for fish farming as it improves the growth rate and productivity of the fish.
