I recorded this video in my labs at the University of Leeds. We have a special lighting lab where we can adjust the spectral properties of the lighting in the room. I started the video and had the lighting automatically cycle through some colours. After a short while it became irritating so I had to pause brlefly and set it to one colour.

We use this lab to carry out various studies into the effects of lighting.

Here’s the video.

Here are some of our fairly recent papers.
