Are you sure the large high-voltage globes you used in theater work have
the same charactistics as the miniature low voltage ones being talked
about here?

One reason I ask is that our local home goods/hardware store sells low
voltage halogen kits with dimmers.  Are they selling a product that
damages itself, or is something different about them?  I have no idea
whether they are or not, does anyone out there know?  One thing I was
able to see from the packaging is that the dimmer goes between the mains
and the transformer.
