This lighting control allows you to switch the artificial stable lighting on or off, on a timer and regardless of existing daylight, or even achieve a constant light level (e.g. min. 200 lux) through automatic dimming. This means it ensures ideal lighting conditions throughout the day and year while minimising electricity consumption. Comfort for animals and humans!

LED technology in the stable pays off

LEDs operate at a high level of effectiveness and are extremely efficient. Their luminous efficacy is thus especially high.

The investment costs for new equipment or a conversion are currently still normally higher when compared to conventional lighting technology; however these costs will pay for themselves over a short amount of time due to the considerable savings in operating costs.

More milk through more light

Lighting duration, lighting intensity and light colour all have a major impact on lactation, fertility and the well-being of animals. In dairy cattle farming, lighting management, therefore, is extremely important.

Scientific studies have shown that daily milk production can be increased 5-15 % on average during long daylight phases with 16 hours of light and 8 hours of darkness. However, this requires a uniform lighting strength of 150-200 lux.

High switching capacity

On – Off – On – Off … Contrary to energy-saving and fluorescent lamps, the robust light emitting diode is practically impervious to frequent switching on/off. Thus they are also well-suited for switch intensive operation on motion detectors.

Immediate full light output

Energy-saving and discharge lamps require a "warm-up time" of almost a minute to reach full brightness. With LEDs, this scenario is a thing of the past because they offer immediate 100 % light output when turned on.

Full light output even at low temperatures

LEDs also operate extremely efficiently at low temperatures and are, therefore, ideal for use in outside areas or in unheated buildings. For example, while an LED tube continues to emit its full light output at an ambient temperature of 0 °C, a typical fluorescent tube, which is designed for ambient temperatures of 20 °C, only emits 40-60 % of its max. value.

Does not attract insects

Insect eyes contrary to human eyes are especially sensitive to ultraviolet radiation (UV). While the mercury vapour high pressure lamps frequently used in the past acted like a vacuum cleaner sucking up millions of insects due to its high share of UV, the light emitted by LEDs are very insect-friendly – it contains practically no UV radiation.

No additional heat input

The light emitted by an LED remains cool – compare that to thermal radiators such halogen or incandescent light bulb lamps for which a large portion of the energy is output in infrared radiation and thus in heat. The electronics of LEDs due in fact produce heat; however, this is not emitted in the direction of the object being illuminated.

Natural colour perception

In dairy cattle farming, a high and natural colour rendering is required for the colour differentiation between blood, urine and milk, especially in treatment areas, sick stalls and calving bays.

The quality of the colour rendering is expressed in terms of the Ra value. The maximum possible value is 100. A Ra value of > 75 is recommended. Contrary to LEDs, sodium vapour lamps, for example, have a very poor colour rendering (Ra 20-50).

Environmentally-friendly and safe operation

Due to its high energy efficiency, the CO2 pollution is correspondingly low. Operation is completely safe and disposal can be made via community collection centres because LED lights do not contain any mercury. Naturally, all of our products meet the requirements of Guideline 2002/95/EC regarding limiting the use of certain hazardous substances in electric and electronic devices (RoHS).
