When the government, and the rest of the idiots ban incandesent bulbs, where will we get replacements?

We who are of the past, still use bulbs to maintain warmth in chick brooders, to keep a water pump and lines from freezing on a dip in temperature below freezing. Toy baking ovens still use them, incubators, antique chandeliers, and lamps, a long list of their use.
