A friend of mine has had good luck using a reptile thermostat to hold heat in his homemade incubator. However, he also uses 4-100W light bulbs as the 'heat element'. It holds heat very well, but personally I'd rather not have lights flicking on and off all the time. Plus, with them doing away with the incandescent light bulbs, I'd have to figure something else out soon enough. I was wondering if I could use a reptile heat cable similar to this as the heating element? Would those put off enough heat? I'd have a fan, so the heat would be circulated. Or would a small heat lamp (100-150W) work? I've thought about using the ceramic heat 'bulbs' since they don't put off light.
