IF YOU WERE A LIZARD..

If you were a lizard and I put you in an arena, do you want a central strong light or 4 separate weaker lights? Why?
  1. Central light means sitting under it for less time for thermoregulation
  2. With a central light the heat is dispersed with an epicentre and gets cooler towards the edges.
  3. Four lights means more movement to get the right temperature
  4. With the Four light the lizard could have a lower thermal tolerance because there is less direct heat.
