The Challenge: Longer Nights, Lower Yields
One of A large and capable farm in the United States farms is located in South Dakota and houses 5,000 dairy cows. shorter winter daylight hours meant more than just chilly mornings. Like many Midwest farms, they struggled with seasonal drops in milk production—a problem costing them $150,000+ annually in lost revenue. Traditional lighting solutions were energy-hungry, and worker safety in dim barns was another concern.
The Solution: USONIC Red-White Night Simulator
In 2023, A large and capable farm in the United States installed USONIC NIGHT SIMULATOR FIXTURE , designed to mimic natural daylight cycles with red (660nm) and white LED spectrums. The lights automatically adjusted intensity and color temperature overnight, aligning with cows’ natural melatonin and prolactin rhythms—key hormones for milk synthesis.
The Results: Hard Numbers, Real Impact
Red-white alternating cow light 33% Increase in Milk Yield
In less than a year, the yield of the cows increased from 18% to 33%, and our farm grew by 6 million dollars!
High-intensity cow lighting 60% Lower Energy Costs
By replacing the 400W metal halide lamp with an 80W LED panel, the monthly electricity consumption can be reduced enough to buy a lot of nutritional needles for the little cow.
Fewer Worker Injuries
Consistent, glare-free lighting reduced tripping hazards during night shifts.
Workers reported better visibility for feeding and health checks.
Why It Worked: The Science Behind the Light
Red Light at Night: Stimulates prolactin without disrupting sleep
Precision Timing: Cow light timer for milk production16-hour “day” (white) + 8-hour “night” (red) cycle optimized cow circadian clocks.
ULC-Certified Durability: Withstood South Dakota’s -30°F winters and humid summers.
Actual case feedback from the farmer
The ROI was obvious. We recovered the Farm animal growth lights upgrade cost in under 11months through milk gains and energy savings. Plus, the cows are calmer—fewer stampedes during night checks.
Could Your Farm Benefit?
With South Dakota’s Agricultural Improvement Grants covering up to 25% of energy-efficient upgrades, A large and capable farm in the United States success story isn’t unique. Calculate your potential savings:
Milk yield: Expect 33% gains in low-light seasons.
Labor: Fewer injuries = lower insurance premiums.
Energy: LED savings offset utility inflation.
