ZL LED Linear Light

LED Linear light for Cow Barn

ZLC LED linear light is designed for Barn and have positive effects on the health, fertility, welfare and productivity of dairy cattle - NO blue light . No UV , Uniform lighting performance with IP65 , Corrosion free . D-mark approve .

With our smart control system -programmable dimming and timing,They offer several advanced features that address the complex needs of today’s modern farming facilities and can both be easily programmed with the accessible display. Setting up the different lighting lever at different time to help the Cows and Cattle waking up with rising sun and end each day with a sunset 

New research brings this statement to light: Proper parlor and dairy facility lighting may play a role in herd performance and an operation’s bottom line. Research from the University of Minnesota shows cows and heifers require adequate light levels on a consistent basis.    The light helps them generate appropriate hormonal responses for optimal growth, milk production and routine movement. Adequate lighting has also proven to increase feed intake when ideal lighting is positioned properly.

There are minimum light levels required for both general inspection and welfare, respectively. Enhanced lighting levels may be required for stimulation of milk yield for the cows or for more visually demanding tasks for the stock men. In such cases, higher lighting levels may have to be provided in some areas for a specific time.Evidence shows that milk output and feed intake of lactating cows is highest with light periods of 16-18 hours per day and with a lighting level of at least 160-200 lux.Long day length would appear to alter the secretion of a number of hormones. Such hormonal shifts are not unique to cows and drive the commonly observed changes in reproductive activity in other species, too. Long days reduce the duration of elevated melatonin and produce higher secretion of the hormone insulin-like growth factor-I (IGF-I). Higher IGF-I is thought to increase milk yield.

On average, it is expected that cows on long days will produce an average of two litres more than control animals on natural photoperiod.

It is important to balance extended daylight with periods of darkness. However, light levels should be maintained around 30 lux to provide the cows with sufficient light to move around the building and exhibit normal behaviour with confidence
