Light Years

The lighting display at the hardware store made me think. How many more times will I need to buy light bulbs?

Advances in technology have resulted in modern bulbs with a life expectancy of ten or twenty years. If they keep developing new light bulbs with longer and longer lives, at some point the bulbs will be expected to outlast me.

I can currently buy bulbs that will last into my seventies. When those burn out, I will probably be able to buy bulbs that will still shine after I’m 100.
