50W Zoo med repti heat cable is what mine is if I remember rightly.
When it's stretched out the single strand gets about 60°C but when coiled together it's absolutely insane !! Needless to say a thermostat is needed lol
But if I'm not mistaken when a heat Mat malfunctions it turns all the way on and burns your snake but when heat cable doesn't it just turns off. . Don't quote me on that tho !
