I recently had a 3-way light bulb blow out, and when I tried to unscrew the bulb--it broke. To my surprise, the filament was still working, providing light. However, my husband was upset saying I should have alerted him because a fire could have started from the exposed filament. Is this really possible?

Answer

Light bulbs work by heating the filament white-hot; so hot (as in the thousands of degrees) that it glows brightly with very white light.

If that bare, 2,000 or 3,000-degree filament comes into contact with something flammable (a curtain, perhaps, or your shirt) an instant fire is almost inevitable.
