Best Answer
Argon does not power light bulbs, electricity does. It protects the filament. Normal air would quickly cause the filament to burn away. Argon does not do this as it is chemically inert. Old lightbulbs contained a vacuum, but it was later found that having an inert gas such as argon present could help dissipate heat better, thus allowing the filament to last longer.
