No need to apologise, its my lack of knowledge. Thanks for helping me understand EL-Ziggy, We sometimes have different names for equipment in the Uk and so different abbreviations, also I am a bit out of date.
That post will help me understand in the future on this site.
I do use under tank heating in the form of heat mats for my tubs in a rack system for ball pythons. heat strips are hard to come by here.
I have used ceramic heat bulbs in the past, but caging them to prevent burns was a pain. Its cold where I live so they tend to have to run well hot.
My incandescent bulb thing is more about pretty lighting for me, but I can only use them with snakes that need a cooler temperature than tropicals.
I do like heat cables. I also use underneath heating in a false floor to boost the temperature for some snakes that need a bit more. combined with some over head heat.
