Yeah, I read about that for burning they skins, but I think this is only by UV ? If I heat it with pad/mat it will be dark in the terrarium. Yes, Grif help me a lot. Thanks all
PS: Quote from care sheet
"a low UVB tube is generally a welcome addition to the terrarium. Not only will it allow you to view your Horned Frog better, but it will also help your Horned Frog to convert some of it’s food intake into vitamin D3. If no UVB can be provided then it is more important to ensure that your Horned Frog’s food is dusted with vitamin D3 regularly.
The exception to the UVB bulb are albino Horned Frogs. UVB should not be used in terrariums housing albino varieties. UV lighting will burn your albino Horned Frogs skin and will eventually cause blindness."
