NEW FOR 2017!!  Now in stock The New Curragh replaceable battery light mask!  

Customers have been asking for a mask with a replaceable battery.  The new design allows the light cup to be replaced the following seasons without having to purchase a new mask. Equilume now has 3 mask to fit your every need.

UPDATE:  I have my personal mares cycling at 70 days on January 19th!! I have them on 3 mares as a test.  2 mares were in heat at 70 days.  To early for breeding so we will catch them the next cycle.

3-1/2017  All 3 mares have been bred, 2 in foal, flushed 1, 3rd mare bred and will check this week.  21yrs old!  the mares that didn't wear mask still have not started cycling.

Now that everyone has the light mask in use for early mare breeding, here are a few tips to insure you get that early cycle you planned for:

Make sure to clean the light source about once of week.  It seems to get a film build up on it.  You don't even have to remove the mask on most horses.  I have found that just rubbing it with your fingers will remove the film. 

Check at night, before 11pm, and make sure all your lights are working at least once a week. Sometimes when things are to easy we seem to forget about them.   Good Luck!

Horse - Equilume Light Mask for horses comes to the USA !!

The Equilume™ Light Mask provides low level blue light to a single eye, it is on an automatic timer and powered to last an entire breeding season..

The Mask contains a light sensor such that the blue light will only stay on for 30 sec once activated until environmental light levels drop at dusk. When low light is detected the blue light will come on for the remainder of the 7 hour active period. If initially activated at 4:00 pm on the first day of light therapy the light mask will automatically switch off at 11:00 pm every night.

The long-life battery has been customized for horses and all-weather conditions. lt will provide precision blue light therapy for one entire season (5 months).

A rechargeable mask is in production and we are hoping to have it available very soon!   Click here to Purchase

Mares cycle early with the Equilume Light Mask:

Horses are seasonal breeders, their natural breeding season occurs during the light- filled summer months.

However, the universal birthday for many horse breeds is Jan 1st (Northern Hemisphere) or Aug 1st (Southern Hemisphere).

These industry wide crucial dates create a demand for early foals, in order to produce mature yearlings and precocious two year old horses.

Changes in the length of daylight is the primary regulator of reproductive activity in the horse. The hormone melatonin is produced during the hours of darkness and acts as the decoder of day length for seasonal breeding animals such as the horse. The time of year is directly translated through this relationship; as the days lengthen in Spring, melatonin production decreases signalling the approach of the breeding season.

Mares foaling during an artificially imposed early breeding season often experience:

  • Longer gestation lengths
  • Lower foal birth weights
  • Post-foaling reproductive problems

Late foaling mares represent economic loss to the breeder by reducing the number of foals a mare can produce in consecutive years. Mares that foal outside of the natural breeding season (e.g. Thoroughbreds) have longer gestation lengths by an average of 10 days. However, 20% of Thoroughbred mares experience annual gestation lengths that exceed 355 days.

Light is the primary influencer of gestation length. Light therapy for 90 days prior to foaling has been scientifically shown to increase average foal birth weights and prevent prolonged gestation.


Field Trial 2012 - Pregnant mares

  • 15 pregnant mares with a history of long gestation lengths were divided into two groups.
  • One group was fitted with prototype Equilume™ Light Masks on Dec 1st


The Equilume™ Light Mask reduced the average gestation length of pregnant mares by 11 days (Walsh et al, 2012. MSc AgrSc Thesis, UCD)

Field Trial 2013

  • A group of 30 mixed breed pregnant mares due to foal Feb - March were selected
  • 15 of the mares were fitted with Equilume light masks on Dec 1st


The average birth weight of foals born to the group of mares wearing the Equilume Light Mask was significantly greater by 8.4 lb

Providing longer day-length for 90 days beginning on Nov 15th (NH)/Jun 15th (SH) acts to reduce the production of the hormone melatonin and stimulates the mare's reproductive system to activate earlier in the year. To achieve this, many breeders stable horses indoors under extended barn lighting and incur substantial costs associated with bedding, lighting and labor.

Field Trial 2012 – Maiden/Barren mares

  • 26 non-pregnant mares were fitted with prototype Equilume Light Masks and maintained outdoors at pasture from Dec 1st
  • 16 mares were maintained indoors under standard stable lighting
  • 20 mares were outdoors at pasture without light (control).


Over 90% of the mares in the group who were maintained at pasture wearing Equilume Light Masks and the group maintained indoors under stable lights were reproductively active on Feb 10th. Equilume is as effective as standard stable lighting at advancing the breeding season in mares. These results were published as a paper in the Equine Veterinary Journal (Murphy et al, 2013).

It is suggested that the mask be activated on November 15th, but no later than Dec.1st to achieve February breeding.

Horse - Equilume Light Mask for horses comes to the USA !!


 Last season, I really put the Equilume Light Mask to the test. I used it on mares that for years would’nt cycle until April or May. With the EquilumeTM Light Mask the mares were cycling by the end of January. Staying outside with the mask is positive for the horse, for their life, for mares cycling, for their hair coat. I look forward to using the mask again this season. I am sold!

The very best device I have seen in 25years of reproductive practice, second only to the introduction of the ultrasound. It will get them bred early.

Debbie and I used Equilume Light Masks on four barren mares and one maiden mare last season at Jackson Purchase Farm. I was a little reluctant to part with proven ways, but I am happy to say that the masks worked great. All of the mares had breedable follicles and had gone through transition by the February 14th. Four of the mares conceived on the first cover while one was more challenging. In the winter of 2014 we had zero issues with the mares being outside 24/7, often in sub-zero temperatures. Besides the fact that the mares all cycled as I hoped, I am still married, spent less on van and vet charges and had healthier mares. Like extended turnout for any class of horse, daily observation, occasional adjusting of masks and adjustment of feed and hay is necessary. For me the economics were good and the mares simply did better outside. I am a believer!"

Does the administration of light to one eye effect the health of that eye?
No, thorough health checks and optical examinations were conducted by qualified veterinarians before and after the two years of trials with Light Mask prototypes. The light intensity used is 5 times lower than normal stable lighting and 100 times lower intensity than daylight on a sunny day.The light is not a bright light but more like a glow. There are holes placed in the eye piece so the horse still has vision from that side.

Are the eyes bothered/damaged at all by the light being so close. If not, why? Thank you. Karen
