HVAC / Exo Terra / CHE 150 watt question

[Bogertophis]

I could be wrong...so correct me if I am!

I thought you shouldn't even use a CHE in a regular dome and had to run the wire cage type because it can really heat up the inside of the dome and melt the components. Or is that only a concern with the larger sized CHE bulbs?

If you use a dome with a CHE, it MUST be the kind rated for that high heat output- and it WILL have a ceramic fixture inside to hold the bulb, NEVER a plastic one that the bulb screws into. The plastic ones will melt.

For safety, it also helps to use a large dome- not the small ones, & even the medium size ones might be an issue. Safety first, please everyone.
