use lamps:

At about 1/10 of their rated voltage.
At about 1/4 of their rated current.
At about 2/5 of their rated hot resistance.

These rules of thumb are just that -- circumstances may require moving up or down the lamp curve depending on other factors, like not being able to find a suitable lamp, which is indeed getting harder and harder.
