Fun with Words! #1

I have decided to start a little segment on the blog, and it is called (points up) Fun with Words! IT goes like this:

1. I give you a German word, including the DIRECT translation
2. You attempt to guess what it actually is (points down to the comments) 
3. Only rule is no German-Enlish Dictionaries, Google Translate, etc.... (I want it to be fun for everyone)
4. If you are fairly fluent in German and know exactly what it is, please try not to ruin the game.

And the first word is:

Glühbirne

Glüh= Glow     Birne= Pear
