Title: Vintage Ceramic heat bulb
Post by: vintageglow on February 28, 2009, 05:06:56 pm

This may not be the place to find out about a heat bulb, please let me know if you can direct me to help. Thanks
I purchased a ceramic cone shaped bulb with a coil filament that wraps around the outside. Does anyone know what this type of bulb was used for ???? vintage heat lamp maybe ??

Yes - these are resistance coils used in vintage electric radiant heaters.  I doubt they have much interest among bulb collectors but they may be useful to those who collect old electric heaters.  This page contains pictures of some old heaters that use these resistance coils:

I remember my 2nd grade teacher bringing in a home-built food dehydrator into class with one of those heaters on the bottom...

If it happens to have a left-hand thread -- i.e., it can't screw into a regular light socket -- then it was made by GE.  They must have made them that way to prevent people from screwing them into lamps or ceiling fixtures  :-)

Hmmm, that's odd...  It's either made for industrial applications for the people down under.  (like the toilet water swirling backwards)
