Light plays an important role in a horse’s natural biological rhythms, influencing seasonal changes in coat growth, reproductive activity, and daily patterns. For horses kept in stalls or managed under artificial lighting, daylight exposure may differ from what they would experience outdoors.

Equilume offers light management solutions designed to help horse owners manage these seasonal and daily rhythms. From breeding-specific light masks to rechargeable options for performance horses and automated stable lighting, the right system depends on your horse’s needs and management routine.

Continue reading to learn how light management works and compare the Equilume products available at FarmVet to determine which option best fits your horse.

How Does Light Affect Horses?

Horses respond to changes in daylight throughout the year. As days become longer or shorter, light exposure influences the body’s circadian rhythms. This is part of what regulate daily biological processes and circannual rhythms associated with seasonal changes.

For breeding horses, carefully managed light exposure can help advance the onset of the breeding season. For performance horses, light management can help support coat management and maintain more consistent lighting routines throughout the year.

Typical artificial lighting varies in intensity, spectrum, and duration. Therefore, simply keeping barn lights on longer may not provide the same controlled exposure as a system designed for equine light management.

That’s where Equilume steps in. Equilume’s light masks and stable lighting systems deliver targeted light exposure according to specific schedules. These options allow horse owners to manage light exposure without relying solely on natural day length.

Which Equilume Light Mask Is Right for Your Horse?

The Belfield Light Mask, Curragh Light Mask, and Pro Light Mask all use targeted blue light technology. But, they differ in their intended applications, power systems, and reusability.

Equilume Belfield Light Mask: Seasonal Breeding Support

The Equilume Belfield Light Mask is best suited for seasonal use. It is a great option for breeding programs working to advance the onset of the breeding season.

By extending perceived day length, the Belfield helps manage seasonal reproductive activity in mares and stallions. In mares, light management can help bring forward reproductive cycling, while stallions may show increased libido and fertility.

The Belfield delivers a programmed period of blue light and is intended for one season of use. Its light cup has a limited lifespan and is not replaceable for reuse in a subsequent season.

Best for: Breeders looking for a dedicated, seasonal light mask to support their breeding management program.

Equilume Curragh Light Mask: A Reusable Breeding Option

The Equilume Curragh Light Mask is another option for breeding programs that want to manage seasonal light exposure. Like the Belfield, it is designed to help advance the breeding season through scheduled blue light exposure.

The key difference is its replaceable light cup. Rather than replacing the entire mask when the cup wears out, owners can purchase a replacement Curragh Cup and continue using the existing headpiece.

This design makes the Curragh a practical option for breeders who plan to use light management across multiple breeding seasons.

Best for: Breeders who want a light mask designed for continued use across seasons with a replaceable light cup.

Equilume Pro Light Mask: Rechargeable Light Management

The Equilume Pro Light Mask is designed for horses whose light exposure needs to be managed beyond a traditional breeding-season schedule. Its rechargeable light cup delivers a longer daily period of blue light. This makes it a great option for performance horses and horses whose routines involve travel, limited turnout, or poorly lit stabling.

The Pro Light Mask is programmed to provide up to 15 hours of daily light exposure. Its rechargeable cup is designed for regular use and charge lasts approximately up to 7 days.

For horses that travel frequently to competitions, changes in barn lighting and daily routines can make consistent light management more challenging. A portable mask offers an alternative to installing a dedicated lighting system at each location.

Best for: Performance horses, frequent travelers, and horses whose daily light exposure needs to be managed throughout the year.

Equilume Stable Light V3: A Lighting Solution for the Barn

For horse owners looking to manage lighting within a stall or stable, the Equilume Stable Light V3 provides a simpler approach.

The system delivers blue-enriched white light during the day and soft red light at night. It has programmed transitions intended to mimic changes in natural light. Its lighting schedule is adjustable to accommodate seasonal day-length changes.

The daytime program provides support for fertility, appetite, condition, and performance, while the red-light setting allows visibility for routine nighttime checks without relying on bright white lighting. This can help reduce unnecessary exposure to white light during the night.

Unlike a light mask, which travels with the horse, the Stable Light V3 is installed in the stall itself. It may be a useful option for owners managing lighting for horses that spend substantial time indoors or for facilities looking to establish a consistent lighting routine.

Best for: Horse owners and facilities looking for an automated, in-stall lighting solution that can be programmed and adjusted throughout the year.

Choosing the Right Equilume Product

The best option depends on how you manage your horse, your goals, and whether you need a portable or installed lighting solution.

  • Belfield Light Mask: A seasonal option for breeding programs that do not need a reusable light cup.
  • Curragh Light Mask: A breeding mask with a replaceable cup for use across multiple seasons.
  • Pro Light Mask: A rechargeable option for longer daily light exposure and performance-oriented management.
  • Stable Light V3: An installed lighting system for programmed light exposure within the barn.

Before starting a light management program, consider your horse’s breeding status, current turnout and stabling routine, and the time of year to determine the best approach.

Light management is one part of a broader horse care program. Nutrition, turnout, exercise, veterinary care, and overall management remain important considerations for supporting your horse’s health and performance.
