With the advent of LEDs and their greater range of colour, it has become too easy to add extra lights, to the point we have overshot the mark, something that Dr Daniel Werner is certain of. Following his doctorate, he has been working on the topic of lighting in livestock buildings and its effect on the stock housed inside.
