HVAC / Exo Terra / CHE 150 watt question

[Armiyana]

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.

You are correct in part. The dome must have the holes near the base to be used with a CHE. That said I never trusted it and only used the wire version.

I mostly remember it being an issue with the smaller domes, even with the ceramic fixture. But that was when I worked retail so who knows what CHE they dropped in there.
It probably was the older style though without the hole in the base. I remember them as having that solid sleek look.

I haven't used bulbs myself because I have nocturnals who love belly heat and nosey cats who love to knock things off cagetops. lol.
Good to know for the future!
