How do I find old light bulbs?

For years I have searched for the old ceramic rings that you place on a lightbulb and put scents onto it. The heat from the light bulb always warmed enough to transfer the scent. I bought two and now I find out that they do not work well with the new cooler light bulbs. Any suggestions of finding old light bulbs that get a bit warm? I do not like to use plug ins for they do not seem to work very long.Thank you.
