Are there any lights on the market that create a light spectrum that's not visible by frogs, that's visible by humans, and creates very little heat?

Since getting my White's- every morning when I wake up- I find little foot prints across the glass in the condensation. The leaves draped across the branches in the terrarium are always laying on the ground too.... My White's are pretty active, but I never get to see them. They sleep in their river rock rock cave that I created for them during the day, and run around during night. I want to disturb them as little as possible so once their light goes off I leave it off.
