Red animal lamp – improving animal welfare through red LED lighting in animal farming: poultry, cows, pigs and horses

Red light for animals It is one of the most frequently studied spectral ranges in agricultural lighting. In recent years, it has gained enormous popularity due to its positive impact on animal welfare, productivity, and health. It is particularly effective in poultry houses, barns, pigsties, and stables, where – with a properly selected LED installation – it can significantly improve breeding conditions and reduce farming costs.

We explain why red light works, what biological mechanisms it triggers, and how to use it safely in practice.

How does red light affect animals?

In the red light spectrum (approx. 620–700 nm) there is energy that:

• stimulates the visual receptor more gently in many species of farm animals,
• does not cause light stress,
• makes orientation easier in the dark,
• influences circadian rhythms by affecting melatonin and cortisol,
• supports tissue regeneration and soothes stress reactions.

In many species, red light also works calmingly, limiting aggression and enabling safe maintenance activities (e.g. feeding at night, checking the animals).

Red LED lighting in poultry farming

Avian physiology studies show that red light reduces the excitability of chickens and broilers because their retinas are less responsive to wavelengths above 620 nm. In practice, this means:

• less risk of cannibalism and feather pecking,
• calmer behavior during feeding and inspections,
• stress reduction and better tissue regeneration.

This is especially important in mobile poultry houses and large farms.

Red light allows the keeper to work at night without disrupting the birds' cycle. Birds see red light less clearly, allowing them to remain in "night mode" while humans have good visibility.

It is important to use flicker-free lamps and ensuring high uniformity – key parameters for our lighting systems.

Red LED lamp in cattle farming

Cows are very sensitive to light disturbances, which is why some people even use daytime lighting or intensity sensors to ensure adequate levels even on cloudy days. Red light, however, has a completely different role. It's used at night and doesn't interfere with melatonin secretion, which:

• improves regeneration,
• stabilizes feed intake and its absorption,
• has a beneficial effect on tissue regeneration and the quality of rest.

Scientists have shown that cows cannot perceive red light, but red light increases contrast at night. This helps cattle avoid collisions with other cattle and equipment, thus avoiding injury.

Red light in pig farming

In pigs, red light reduces hyperactivity associated with stress, anxiety, and aggression. It is used in applications such as:

• maternity wards,
• nurseries,
• fattening farms,
• treatment rooms.

However, red light is most often used during and after insemination. Red light has a significant impact on hormone production and sperm acceptance. Using red lighting at night reduces the risk of fighting, especially in mixed groups or during the weaning period.

Red LED lamp: safe night-time control of sows

Breeders emphasize that red light allows:

• litter control,
• checking feed and water,
• performing minor procedures,

without stimulating sows and piglets, which reduces the incidence of crushing and sudden, stressful reactions of animals.

Red light in horse breeding

Horses have a specific vision – they see well in dim light, and perceive red light as exceptionally mild.

Red night lighting:

• doesn't wake up the horses,
• reduces symptoms of stress (kicking, spinning, nighttime neighing),
• makes it easier for the staff to check standing, feeding and health checks.

Red light therapy for horses

Red light is also used in equine physiotherapy – it aids muscle regeneration and improves microcirculation. Many breeders use red lamps to stimulate faster regeneration – mitochondria initiate optimal energy production, which is used for collagen production, improves circulation, and regenerates damaged tissue. Its properties related to wound healing, rehabilitation, and recovery after intense physical exertion, such as competition, are particularly valuable.

How to choose the right LED systems for animal husbandry?

Regardless of the animal species:

• red light cannot be too intense,
• uniformity of lighting is key,
• lamps must be flicker-free and ready for many years of operation.

Summary – The impact of red light on well-being

• less stress for animals,
• calmer nighttime behavior,
• safer operation,
• more stable circadian rhythm,
• the ability to work at night without stimulating the herd,
• improvement of hormonal balance,
• improved regeneration, quality of rest – better immunity, feed absorption and egg and milk production,
• fewer injuries and production losses.

Red light for animals is one of the most effective tools for improving animal well-being and organizing work in livestock facilities.

Combined with simple, durable, flicker-free LED lamps with high light uniformity, it is the most practical solution for the modern farmer.
