Question: Why does the ONCE lighting for broiler light have a red and a blue light output? Our products are designed the way poultry visualize light to maximize their growth potential. This is why color matters.

Question: Why is red light significant for layers? Red light stimulates the production of neuropeptides in the hypothalamus, which is known to regulate reproduction in laying hens. Dimming to red in the evening will also increase the circadian experience of the laying hen, which will reduce stress.

Question: What does the Dim-to-Red recipe do? The Dim-to-Red light recipe creates contrast in the intensity and spectrum throughout a cage-free system and prevents potential floor eggs.

Why is blue light significant for broilers? Blue light has many benefits for broiler performance and welfare. Studies demonstrated blue light can positively impact muscle growth and bird welfare while reducing FCR.”

Question: What impacts does lighting have on animals? Light impacts all living organisms. But natural daylight is ever-changing. No matter what the season, or time of day. For animals, that has a real impact on their hormonal processes and behavior.
