No this was not a vivarium

This thread tight and well. 220 v. 15 W it is certainly suitable for a vivarium, but in my case, it's to protect an engine from cold and humidity; when it is not started. 7w per meter is a little small for that. Otherwise, it's very correct equipment. Preferred 50 W to resist against frost, although the wire is a little long. We must surround the engine and the manufacturer of this thread do not recommend touching son, complicating the motor entourage is small and not very accessible (boat)
