If you are like me, your drop cord light bulb will break with minimal provocation. After replacing two bulbs in a week due to broken filaments, I decided to try a screw-in flourescent bulb. I am pleased to report that the bulb works great! An additional benefit is that it doesn't get hot enough to burn your skin if you brush against it. They cost around $5 each. Mine just survived a fall from the work bench with no damage.
