Do Ceramic Heat Emmiters glow??

[pga7602]

Can someone tell me if Ceramic Heat Emitters are suppose to glow. I've never used these before and thought I would try it. I bought two Exo-Terra 100w Ceramic Heat Emitters and have installed them in exactly the same type of fixture. Tonight, I noticed that one glows a dim red/orange at the bottom of the bulb and the other one does not. They seem to be emitting same amount of heat.

So which one is faulty? Thanks in advance.

No. They do not glow at all. Something is not right somewhere, unless they are making some sort of new style that I have not seen yet. Can you post a pic?

Sorry, I can't get the camera to read the red color.. One is def glowing and the other is just black. I guess I'll go return the glowing one.

the mystery continues... Now they are both not glowing and both are still emitting heat. Is there a thermastat in these things that kicks in turbo mode when it gets too cold? Let me know.

Definitely return the glowing one. These are not supposed to glow only emit heat.

Ok, mystery solved.. the one that had glowed killed itself. It no longer gives out heat... MADE IN CHINA... SCARY....

According to their website, their ceramic heat emitters do now emit any light.

WHat is the differnce in the heat emitters and a reg heat bulb? I've wondered this for a while now as I read post suggesting that people shoud switch however I don't know the difference what are the pros and cons? Think you can help or would I be better looking/starting a new thread?

Both give off heat. The ceramic heat emitters are useful for a night time situation when you do not want light. Perhaps the animal will not rest as well with an illuminator in their enclosure. Or if the enclosure is in a bedroom where it needs to be dark at night.
