This new spectrum of light 630nm maintains sleep cycles for nocturnal animals such as mice and rats.

Red light for nocturnal animals.

Using red light for night vision is less effective for people with red green color blindness due to their insensitivity to red light. Nocturnal animals are likely to be especially affected but how they respond to artificial light is still largely unknown. Research facilities commonly use rodents for study and therefore must address the issue of proper lighting for these nocturnal animals. Red led lighting is ideal for animal research laboratories.

The most important consequence of this for viewing nocturnal animals is that red light does not harm their night vision and they continue to function normally when illuminated with red light. With red light you are able to watch and photograph nocturnal animals behaving naturally. Need quotation to verify many animals have a tissue layer called the tapetum lucidum in the back of the eye that reflects light back through the retina increasing the amount of light available for it to. Night time light pollution is rapidly increasing across the world.

The photo below of a nesting powerful owl was a 1 3 second exposure at f6 3 and iso 6400 illuminated with the headlamp shown above. Red light led is the traditional go to light color for most seasoned hunters. I observed this nest for many years using red. However the green light led is gaining popularity especially for hunting feral hogs and for good reason.
