Cattle production can be improved by optimising the welfare needs of the animal while minimising running costs. Lighting intensity and spectral quality play a significant role in controlling cattle’s reproductive cycle and its overall growth and performance. The cost of production can be reduced through installation of a well-designed and efficient LED lighting system.

BioLumen’s AgriRay lighting range provides a tailored and economical solution to delivering real welfare benefits with reduced running costs in difficult operating conditions. High ammonia and humidity alongside variable temperatures are features of most animal production systems and this has presented real challenges to traditional lighting systems, such as fluorescents, when used with indoor and outdoor rearing enclosures.

The absence of any adequate control on the intensity and quality of light delivered by current animal lighting technologies, coupled with the ongoing costs of bulb replacement, means farmers are trapped in a cycle of inefficient energy use, with no biological dividend and therefore no improvement in production. Upgrade to AgriRay LEDs and make your lighting work for you, now, and in the future.

Cattle and Light

Cattle have a wide field of vision and they have well developed but un-pigmented eyes with a blue reflecting tapetum that improves vision in low light but causes poor sensitivity to colour variations in short to medium wavelengths, even in good light conditions. There is much better discrimination between short/medium wavelengths and long (orange/red) wavelengths. This probably reflects a common higher vertebrate arousal response to red colours recognizing the survival value of a vigorous response to the colour of blood. Cattle also have poor depth perception, which is why they are reluctant to enter dark or shaded areas. Cattle tend to move towards light, but are sensitive to harsh contrasts of light and dark within housing facilities.

Most current lighting applications in dairy barns are dated, inefficient and offer inconsistent levels of illumination, resulting in wasted energy and sub-optimal welfare of the livestock. Incandescent and high-intensity discharge lamps, the only option for dairy farmers for decades, were energy inefficient and had a short lifespan, while their lack of control could never fully meet industry needs. Fluorescent tubes and halogen, the most widely used form of lighting in dairy farms, are more energy efficient, cheaper and longer lasting, but, nonetheless, still waste much of their energy on heat production. Fluorescents are difficult to operate at low temperatures and expensive to control in terms of dimming. There is also the potential of harm from mercury amalgam used in the manufacture of fluorescent lamps. If damaged in situ there is a risk of mercury contamination on animal feed and bedding.

Why Choose AgriRay LED Lighting?

The potential financial and production benefits of Light emitting Diode (LED) lighting are still widely ignored in dairy farming

AgriRay LED Lighting is efficient in delivering light where it is needed and is easily and cost-effectively controlled. Large decreases in energy input in dairy facilities can be expected, potentially saving up to 70% of electricity used for lighting over five years.The long life of AgriRay LED emitters – up to 50,000 hours – helps producers save on the maintenance costs of replacing fluorescent tubes, as recommended, every 8-12000 hours (to avoid the impact of degradation of the phosphors on output and spectral quality).

Uniquely, AgriRay LED lighting produces the correct light intensity to ensure good milk flow. AgriRay can provide a range of optical lenses in a single lighting fixture, greatly minimising dark areas and resulting in calmer cattle that can be moved more easily than fearful ones.

AgriRay LED fixtures contain no mercury and therefore there is no risk of contamination.

For the first time AgriRay LED lighting offers complete control over the delivery of the appropriate light intensity and spectral quality, at all times of the day and for all stages of dairy production. The AgriRay lighting range has been developed with a unique understanding of how the right lighting choices can improve the well-being and productivity of your livestock.
