HATO Light Academy

The right light climate is of essential importance for the performance and well-being of animals. For more than forty years, we have been at the forefront of developments in agricultural lighting.  The HATO Light Academy is unique in its kind. This is where you can learn everything there is to know about the effect of lighting on animal behaviour. Animals are often more sensitive to light than people are. This means that agricultural lighting can stimulate desirable behaviour in animals. Undesirable behaviour can also be controlled by a correct light climate.



The HATO Light Academy consists of several lessons. You can follow these one-by-one so that you, too, can become a specialist in lighting. The lessons are categorised by application type and then divided into phases. At the end of each lesson, you take a test. If you pass, you will receive a genuine "Light Certificate."

It is well known that poultry can see more than humans. This module gives you detailed information on this subject.


There are two type of photoreceptor cells located in the retina of the eye, rods and cones.

  1. Rods are responsible for vision during scotopic conditions (low light conditions)  
  2. Cones are responsible for vision during photopic conditions (well-lit conditions).

Response to stimuli, sensitivity to light and dark adaptation are three properties of cones and rods, see figure 1. Rods have a large, slow response, but high sensitivity to light stimuli. This means rods are so effective they respond to very dim light, they however are less accurate in sensing changes in light conditions than cones.

Cones have a small, fast response, but low sensitivity to light stimuli. Because of this cones perceive finer detail and are very effective in sensing changes in light conditions. Cones are ineffective in dim light, but allow the perception of colour. Poultry cones differ in properties and number from human cones which causes a difference in colour vision.


Spectral sensitivity

Poultry have four different kind of cones*, humans have three different kind of cones. Apart from the fact that poultry have an additional fourth cone, the cones have a greater spectral sensitivity than those of humans as well, see fig. 2. Because of the difference in spectral sensitivity for the different wavelengths, there is a difference in the perception of light intensity.

Because of this...
