I have read that running halogen lamps on reduced voltage will shorten
their life, the argument being that their life depends on a cycle of
tungsten sublimation and redeposition which requires a certain
temperature to work. However, it seems to me that at lower
temperatures where it doesn't work (so well) it is not needed, i.e.,
tungsten/halogens should have the same kind of life/voltage graph as
ordinary vacuum tungstens.

Can someone who knows confirm or deny this?
