Light Mask

The Equilume Light Mask is an individual headpiece for horses that provides timed, low-level blue light to a single eye to effectively deliver all the benefits associated with long summer days. Scientifically validated and veterinary evaluated, mobile blue light therapy affords owners the benefits of ease of management, and horses the freedom of natural behavior and improved health and well-being.

The Equilume Light Mask permits efficient light management whether horses are indoors, outdoors or on the road, and it ensures early reproductive success and maintenance of coat condition and summer vigor for competition animals. Our new models (Curragh & Cashel) allow you to detach the cup for replacement or recharging when needed, permitting reuse of the headpiece for multiple seasons.
