Well, it's the boots problem all over again.

A good pair of boots is expensive, but will last for many years.

Cheap boots are more expensive in the long run, because you're lucky to get a year out of them.

You don't have to replace them all at once. Just doing one at a time, starting with the one that's on the most, would work fine.

I'm also doubtful that the average poor person has 50 light bulbs.

If I were a renter, I think I'd take my good bulbs with me when I moved, replacing them with dollar store cheapies.
