  1. They make too much UVB
  2. They lower humidity to zero
  3. They can burn the lizard ✔

Why: A reptile may stay on a hot surface without moving away soon enough. Use protected, regulated heat that creates a gradient instead.

Huh, didn't know that: The same guide says never to put a heat source, like a heat rock or mat, in direct contact with a lizard.
