- 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?
