“I recently got a leopard gecko placed in a wooden terrarium. For heating, I opted for a ceramic lamp. However, I am noticing a problem. Above the warm den directly under the lamp if I set it to 30-32°C degrees in the den the temperature at ground level remains around 26-27. To bring the temperature in the den to at least 28°C above the den I get to 40°C. How would you advise me to optimize?”

The key thing to remember here is that animals will hide away in holes, burrows and crevices to rest, sometimes hunt, avoid predators, escape extremes in weather and cool down.
