What Matters Most in Cattle Barn LED Lighting?

Independent studies on cattle barn lighting show that proper illumination in cattle shed must be tailored to the type of cattle itself and barn conditions. The following factors are essential to improving cattle health, fertility, and milk yield:

Proper LED Lighting Solution for Cattle Barns

Cattle require a minimum light intensity of 150 lux.

A lighting schedule of 16 hours of light at no less than 150 lux, followed by 8 hours of darkness, has proven effective in enhancing production and welfare.

Light exposure directly influences melatonin, the “sleep hormone.” Bright light suppresses melatonin, keeping cows more alert and active, while darkness restores hormonal balance. In short, longer light periods promote healthier, more productive dairy cattle.

Correct Light Intensity and Duration

Proper light intensity and duration are closely linked to the health, fertility, and productivity of dairy cattle.

Balanced illumination helps regulate hormone levels, which can increase milk yield by up to 15%.

Uniform lighting across the barn improves visibility and makes heat detection (oestrus) easier.

Consistent lighting conditions also shorten calving intervals and help identify health issues earlier.

In summary, the right lighting conditions ensure that cattle remain active, fertile, and healthy.

Guide to Optimizing Cattle Barn LED Lighting

Use this quick checklist to fine-tune your barn lighting for optimal cattle performance:

Photoperiod: Maintain 16 hours of light and 8 hours of darkness daily.

Light Spectrum: Choose white-spectrum LED lighting to mimic natural daylight and encourage daytime activity.

Uniform Intensity: Arrange fixtures evenly to avoid dark spots that may stress the herd.

Regular Maintenance: Clean lamps every few months and replace dim or damaged units to maintain consistent brightness.

Avoid Blue Light Exposure

Excessive blue light can cause stress and nervous behavior in cattle, negatively affecting their health and milk production.

Avoiding blue light leads to:

1. Improved feed intake

2. Reduced stress levels

3. Enhanced growth and productivity


An optimized cattle barn lighting system with proper light intensity, duration, and spectrum can dramatically improve dairy performance: boosting milk yield, fertility, and overall welfare, while ensuring healthier, calmer herds.

Livestock lights T21

The T21 Series LED Barn Light is engineered for livestock farms, food processing facilities, and other environments that demand high-pressure cleaning—such as car washes and agricultural barns.

Featuring special ceramic LED technology, durable PC housing, and a fully waterproof structure, the T21 light delivers exceptional resistance to hydrogen sulfide, ammonia, and other corrosive gases. Its ceramic LED design provides over four times higher resistance to hydrogen sulfide–induced light decay compared to conventional LEDs.

Built for high-temperature and high-humidity environments—including mushroom cultivation rooms and areas with heavy dust, smoke, or moisture—the T21 Series also functions effectively as a standard tri-proof LED light fixture, ensuring long-term reliability and stable illumination in the toughest conditions.
