Modern management methods mean that horses can spend a large proportion of the twenty four hour period in their stable with no exposure to daylight and many are disrupted by illumination at night. This system negatively impacts the horse’s circadian rhythm (body clock) and can result in lack of appetite and poor performance, impaired growth and diminished immune response. 


DairyLight, the sister company to HorseLight, has had over a decade of success in the dairy and beef industry. HorseLight has now been introduced to provide the equine industry with biologically effective light.



Paragraph Introduction about the benefits of HorseLight to leisure horses.

Better daytime alertness,  improved rest and sleep patterns

Extends summer coat and body condition, encouraging the body to convert feed to muscle mass, meaning less feed required

Owners report “happier” horses that are stabled, commenting that they appear more relaxed and with noticeably fewer stable vices such as box walking, cribbing, weaving etc
Reduced bacterial pathogens and fungal load leading to improved respiratory function and reduced cases of highly contagious fungal health threats

Many performance horses spend more time in their stable than they do outside, perhaps even more during the summer due to competing and training. There are also many occasions when turnout just isn’t an option due to illness, injury or lack of space.

By installing HorseLight you can be assured that your horse will gain from the huge range of health benefits that this unique light offers.

Improved food conversion leading to increased condition and muscle mass.
Owners have reported having to feed less hard feed as the uptake in nutrients is significantly higher than that of horses stabled without HorseLight.  A saving on feed bills

Improved Vitamin D production in the skin. Horses get their much-needed vitamin D which is essential for calcium absorption through their skin. Stabled horses during the summer miss out on this vital sunshine ingredient which can lead to tying up, skin and coat conditions and many other health implications

Summer coat extending well into late autumn and a less dense winter coat, meaning less clipping is needed

Owners in all disciplines report an increase in athletic performance, improved growth rates in young horses and much faster recovery times

The summer is the season where performance is optimized, infections are lower and alertness maximized. In humans, animals and plants alike it represents the seasons growth, prosperity and wellbeing.

By extending the summer season at each end by using light and controlling melatonin secretion, the peak performance period can be extended.

Horse Race

Maintain summer condition

Enables breeders to forward cycling in mares and ready stallions


Improved exercise response

Can reduce gestation length and promote higher birth weights


Improved food conversion to muscle mass

It has long been acknowledged that the introduction of light into the breeding cycle of mares in the winter months would bring them into season earlier.


Horses are known as “long-day breeders” this means that their normal cyclic activity is primarily activated by an increase in the length of daylight in early spring. With technology now enabling us to select specific light spectrums and intensty and at different times of the year, we can optimise biological performance.

Mares come into season earlier with stronger signals, have a more reliable ovulation pattern and results show a higher first-time conception 

Competition mares who are embryo transfer candidates will benefit from an earlier breeding season. 

Stallions display an earlier reproductive capacity 

Can help with producing earlier foals which is desirable in some disciplines (racing) and improves their growth rate

Stimulates early renewal of the reproductive cycle after foaling

The red night light acts as an observation light during foaling
