If you'd been paying attention, you'd have seen that his most-recent
remark (above), though correct /out of context/, has nothing to do with
the issue at hand.

** What "issue" is that ??

There are actually two issues.

One... A halogen lamp has to run at or above the temperature at which the
tungsten is redeposited on the filament more rapidly than it evaporates.
This temperature is presumably well-above the temperature of a conventional
incandescent lamp. It's reasonable to assume that reducing the filament
voltage some unstated amount

The title of this thread is "Running at half the voltage."
