Arena lighting quality affects both the safety and welfare of horses working in indoor and lit outdoor facilities during winter months.
Arena lighting is a welfare consideration that intersects with safety — a horse that spooks due to shadows or lighting changes creates risk for riders and horses alike. The horse's visual system differs from ours: they have a wider field of view and better low-light sensitivity, but their ability to adjust rapidly between bright and dark is more limited. Arena lighting that creates a hot centre and dark corners creates exactly the conditions for spooking and anxiety. Well-designed, even lighting with appropriate colour temperature that avoids harsh glare and deep shadows creates a welfare-positive work environment for horses and reduces rider safety risk simultaneously.
