How LED lighting makes happy cows - case study

  1. 1. How LED lighting makes happy cows And even happier dairy farmers
  2. 2. Happy Cows Dialight •Body text2
  3. 3. Happy Cows Dialight •Body text This is the Donker dairy farm in the Netherlands – a state-of-the-art family owned business. Its home to 170 cows producing over 1.3 million litres of milk annually.3
  4. 4. Happy Cows Dialight •Body text Have you spotted the bovine waterbeds? That’s not the only innovation. The Donkers had a good reason for looking at a new lighting solution to replace their high pressure sodium lights.4
  5. 5. Happy Cows Dialight In 2003 a report found that cows produce more milk if the barn lighting is improved to a certain level … 16 hours daily at 150-200 lux followed by 8 hours darkness. But adding more light could be expensive with electricity costs rising. And high pressure sodium fittings need frequent maintenance.5
  6. 6. Happy Cows Dialight The solution Instead of high pressure sodium high bays drawing 480W, the Donkers installed Dialights 150W LED high bays. Each carries a 5-year continuous performance warranty, so there’s no more maintenance expense and hassle.6
  7. 7. Happy Cows Dialight The result No more yellowish glow. Instead the light is more like daylight (217 lux shown here) And theres no light spill to the surrounding neighbourhood (a sensitive issue in Holland).7
  8. 8. Happy Cows Dialight Even better Unlike high pressure sodium lights which take several minutes to come on, LEDs have instant-on ability. That means you can turn them off and on as needed.8
  9. 9. Happy Cows Dialight Even better Unlike high pressure sodium lights which take several minutes to come on, LEDs have instant-on ability. That means you can turn them off and on as needed. And more … they can be dimmed from 150W to just 30W to supplement natural light.9
  10. 10. Happy Cows Dialight •Visibility is now better •Energy costs and CO2 emissions are down by as much as 90% when using dimming, 70% at other times •Barn workers can now see colours properly to identify animals by their ear tags and spot injuries or other animal welfare issues10
  11. 11. Happy Cows Dialight •Smaller and cooler running than HPS fittings, the LEDs collect less dust and dirt •They emit no UV, so attract fewer insects •Milk production went up almost immediately by 5% •With the combination of the waterbeds and the lighting, its anticipated to go up by as much as 15% •The farm has drastically cut operational expenses, improved production and created happy, healthy, productive dairy cows.11
  12. 12. Happy Cows Dialight Installation snapshot •1,900 sqm facility •24 x 400W HPS replaced by 24 x 150W LED high bays •70% energy saved on full power •90% energy saved by dimming •No light spill •Reduced CO2 emissions •5-year warranty = no maintenance •Improved light quality •Increased productivity12
