There are many different work areas in agricultural facilities with different lighting requirements.
Stables for dairy cows, cattle, pigs, horses etc., equipment halls, hay, straw and grain stores, barns, cooling and storage rooms, common rooms, washing, showering and changing rooms etc.
Traffic zones, parking spaces, entrances and exits, loading and unloading points, vehicle washing areas, silos, etc.
Ammonia - the special challenge
The reliable, efficient and species-appropriate illumination of stables is a particular challenge. LED luminaires for this application not only have to withstand mechanical loads and intensive cleaning processes with high-pressure cleaners, but also chemical loads, especially ammonia.
Depending on the concentration, ambient temperature and exposure time, significant decreases in luminous flux, significantly shortened lifetimes and damage up to total failure are possible. LED and ECG must therefore be reliably protected. Our special LED light fittings for areas contaminated with ammonia take this fully into account. Of course, tested and confirmed by the DLG (German Agricultural Society) test mark.
In addition, SCHUCH supports the InnoLED_4_Livestock research project as an exclusive industrial partner with its innovative LED lights for agriculture and livestock farming and is thus committed to increasing animal welfare.
The research project “InnoLED_4_Livestock - Increase in animal welfare through innovative lighting technology” was launched in 2017 as part of the innovation funding from the Federal Ministry of Food and Agriculture.

- Standard LED damp-proof luminaire of the 163 series
- LED damp-proof luminaire with LEDs of increased ammonia resistance 163 LW
- Gas-tight LED damp-proof luminaire PRIMO LW
Starting in April 2019, the luminaires were installed over a 21-month period in the pig fattening area, where the highest ammonia loads were expected. The installation was carried out in parallel with the existing luminaires in the selected fattening area, using the same switching procedures. Switching the luminaires on and off creates temperature differences in the luminaires so that stable air is drawn into the luminaire housing. The luminaires were removed every 2 months and measured for changes in lighting technology.
The project is now complete and the results have been analysed and published in a final report.
In contrast to many other studies and tests which only look at the ammonia resistance of luminaire materials, this project looked specifically at the effects of ammonia exposure on the photometric performance of luminaires. Only this approach allows a clear statement to be made as to the suitability of the luminaire for use in ammonia polluted environments.
Standard LED luminaires
The results have made it clear that the use of standard luminaires in stable environments with high ammonia concentrations is not advisable. The gases have a strong effect on the LEDs. There was a clear, continuous decrease in luminous flux of around 10-13% and a continuous increase in colour temperature due to progressive corrosion on the LED. The life of the luminaire is significantly reduced and replacement of these luminaires would be necessary to maintain good lighting in the barn.
LED luminaires with increased ammonia resistance (LW versions).
The luminous flux and colour temperature of these luminaires remained almost constant. The changes were within the measurement tolerances.
The SCHUCH damp-proof luminaires in LW versions, which were specially developed for use in livestock farming, are already ideally suited for use in agricultural livestock farming.
Gastight LED lights (PRIMO XR 107..)
No significant changes have been made here. Thanks to the special gas-tight design of the PRIMO XR with its moulded FastConnect, ammonia gases cannot even penetrate the interior of the luminaire. The delicate LEDs are perfectly protected. This makes PRIMO LW the safest solution for use in livestock areas with high ammonia levels.
The results of the research project have impressively confirmed the harmful gas resistance of both the LW luminaires and the PRIMO XR.
Good stable lighting - more yield
Light not only controls the biorhythm of humans but also of animals. Good, species-appropriate barn lighting promotes the well-being and health of the animals and has a positive effect on their performance.
For dairy farming, this means higher milk yields. Because good, uniform lighting without light/dark zones, for example between the barn, paths and milking parlour, increases the daily milk yield, especially in the dark season.
In pig farming, optimal lighting leads to better visual perception of the animals and thus ensures a significantly lower level of stress and aggression. The animals are more balanced, the meat is better and the yields are higher.
Poultry needs light that is as flicker-free as possible. Infinitely dimmable light with a low flicker index is therefore indispensable for species-appropriate poultry farming. It has a calming effect and reduces cannibalism and death rates. Good lighting promotes in addition the hens' willingness to lay eggs and the growth of fattening poultry and thus increases the yield.

In addition to basic requirements such as adequate impact resistance and resistance to harmful gases, lighting in livestock farming must also meet the special housing conditions and requirements for animal welfare. So which light fitting is the right one for which application?

1) According to the animal welfare and livestock keeping regulation, dimmable versions are required.
2) Since light fittings in poultry houses often have to withstand increased cleaning and disinfection requirements, the PRIMO XR LW DIMD is the best choice.
Extreme conditions often prevail such as very high ammonia load, high humidity, higher temperatures (piglet rearing). The additional intensive cleaning processes with high pressure / steam jet cleaners require extremely robust luminaires. If you want to be on the safe side, opt for the absolutely gas-tight, IPX9K-tested PRIMO XR LW or, for mounting heights over 6m, for the DUEVO LW.
- cattle / cows
Their eyes adapt the light much more slowly than the human eye. Large differences in brightness and abrupt changes in light level frighten and unsettle the animals. Therefore, dimmable versions and a high level of uniformity of lighting are advantageous. The ammonia load is rather low and intensive cleaning processes are rare. Our LUXANO LW and DUEVO ER are the right choice.
Horses also react unsettled and startled to abrupt changes in light level. Therefore, the use of dimmable lights is recommended.
According to the Animal Welfare and Farm Animal Husbandry Ordinance, artificial light in poultry must be "flicker-free", as the animals are very sensitive to flickering light. Many LED light fittings are unsuitable for such areas because of their high residual ripple or pulse width modulation (PWM) used for dimming. Quite in contrast, our dimmable LW luminaires have very low residual ripple and are flicker-free! Dimmable lights also allow the use of different lighting programmes to control the dark and twilight phase in the day / night rhythm.
