Heat mat problem

[Mentat]

...I gotta a friend who can lend me a ceramic bulb, but I have read these bulbs are problematic...
Enclosure is 45x45x60 and my frog is a milk frog (with what it supposes: coco fiber and husk fiber, so many natural plants, 80% humidity...)
Black bulbs dont heat too much... do it?

How are ceramic bulbs problematic? According to my experience ceramic heat emmiters work fine. You have to ensure they are the correct wattage for enclosure size and because of their higher watt rating are usually used with either a manual rheostat or automatic thermostat.

Black bulbs heat according to their wattage rating. They just emit little light due to their design. Have a nice weekend !

My mat has never felt hot to the touch, I can be wrong but I have read and was told to be careful with heat lamps as they can dry out the frogs skin.

If it is an exo terra mat it will not produce enough heating. I had serveral once including desert but never got my temperature up. You want to buy an infrared 15W-20W heatmat. In my 45x45x45 vivarium with a 14W heatmat temperature goes up to 27.4 degrees with a thermostat @27 degrees. Make sure to have a thermostat or else you'll fry the frog.

My mat is attached to one side of the vivarium(it was attached by tape to see if it is good enough to heat the terrarium). Make sure to have all the heatmat surface in contact with the glass of the vivarium or you will loose thermal conductivity.
