I've replaced many of my day-to-day bulbs with halogens in a regular bulb mount. I love, love, love them. They're more expensive than regular bulbs (maybe $3 a bulb), but they have the advantages of regular incandescent bulbs (instant on, no flickering, can be dimmed) along with a whiter light. Their only real problem is that they seem to be hotter, so you have to be more careful about cheap lamp.
I just hope US laws don't outlaw them.
I have a halogen Artemide Tizio lamp that I purchased in the Eighties (I think they’re still available). The only complaint is the unique fitting that will only except a few halogen bulbs. The upside is when someone calls, I bend the lamp down to keep my toast or pasta warm.
Just ask Lionel Hampton.
OK. You can't ask him, because he's dead. But in 1997 he lost everything he owned in a fire started by a halogen lamp in his apartment.
